Flat-Bottom Stand-Up Bag, Vertical Form, Fill, And Seal System And Methodology

For Utilizing The Same

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional application no.

62/134,877, filed on March 18, 2015. The entire contents of the aforementioned application are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

[0002] This disclosure relates to a flat-bottom stand-up bag, a vertical form, fill, and seal (VFFS) system and a methodology for utilizing the same.

BACKGROUND

[0003] Flat-bottom stand-up bags typically contain deposited materials such as, for example, foodstuff (e.g., cereal, chips, popcorn, candy, nuts, or the like). Known flat- bottom stand-up bags include several design deficiencies that may result in, for example, an undesirable entrapment of the deposited material between folds of the material defining the bag, which may contribute to an imbalance of the bag. Such imbalances of the bag may result in the bag not being arranged in an upright orientation, thereby requiring an external structure such as a box or other fixture to ensure that the bag remains properly orientated on a display shelf. Without support from such an external structure, the bag may be susceptible to tipping over which, in turn, prevents a consumer from easily identifying the contents of the bag. While such external structures adequately support a bag on a display shelf, such structures add to the overall cost and complexity associated with packaging and displaying foodstuff.

SUMMARY

[0004] A vertical form fill and seal system is provided and includes a spindle that rotatably supports an elongated sheet of material defined by a plurality of material segments, whereby each of the plurality of material segments includes a first aperture and a second aperture formed through the sheet of material. The system additionally includes a forming tube sized for drawing a left edge and a right edge of the elongated sheet of material together in an overlapping configuration to form the elongated sheet of material into a substantially tube shape and a sealer sized for sealing the left edge and the right

I edge of the elongated sheet of material to one another to form a longitudinal seal. A gusseting mechanism is also provided and is sized for forming a gusseted tuck in each of a left sidewall panel portion of the substantially tube-shaped elongated sheet of material and a right sidewall panel portion of the substantially tube-shaped elongated sheet of material. A sealing mechanism folds and seals a first segment of the plurality of material segments at the first aperture and at the second aperture to provide an end wall of the first segment with a substantially flat, rectangular-shaped footprint.

[0005] In one configuration, the system additionally includes a cutting mechanism that severs the first segment from a second segment located downstream from the first segment. The cutting mechanism severs the first segment at an opposite end of the first segment than the end wall following formation of the end wall to sever the first segment from a third segment located upstream from the first segment.

[0006] In one configuration, the cutting mechanism and the sealing mechanism form an integrated machine. The integrated machine may include a substantially "K" shape.

[0007] In one configuration, the cutting mechanism and the sealing mechanism cooperate to provide a sealed edge at the end wall that has a pair of legs extending from a cross member that joins the pair of legs. The legs extend from the cross member at an obtuse angle and away from one another.

[0008] In one configuration, the cutting mechanism and the sealing mechanism cooperate to provide a sealed edge at the end wall that has a substantially "U" shape.

[0009] In one configuration, the first aperture and the second aperture include a substantially triangular shape, whereby the triangular shape has a base that is substantially coplanar with an outer edge of the first segment. Additionally or alternatively, the first aperture is formed through the left sidewall portion and the second aperture is formed through the right sidewall portion.

[0010] In one configuration, the first aperture includes an edge that is substantially coplanar with an outer edge of the first segment.

[0011] In another configuration, a vertical form fill and seal (VFFS) system is provided and includes a support rod that rotatably supports an elongated sheet of material defined by a plurality of material segments and a forming tube sized for drawing a left edge and a right edge of the elongated sheet of material together in an overlapping configuration to form the elongated sheet of material into a substantially tube shape. The VFFS also includes a sealer sized for sealing the left edge and the right edge of the elongated sheet of material to one another and a gusseting mechanism sized for forming a gusseted tuck in each of a left sidewall panel portion of the substantially tube-shaped elongated sheet of material and a right sidewall panel portion of the substantially tube- shaped elongated sheet of material. A cutting mechanism removes a first portion and a second portion of a first segment of the plurality of material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall of the first segment with a substantially flat, rectangular-shaped footprint.

[0012] In one configuration, the cutting mechanism severs the first segment from a second segment located downstream from the first segment following formation of the end wall of the first segment. The cutting mechanism severs the first segment at an opposite end of the first segment than the end wall following formation of the end wall to sever the first segment from a third segment located upstream from the first segment.

[0013] In one configuration, the cutting mechanism is disposed upstream from the forming tube. In another configuration, the cutting mechanism is disposed downstream from the forming tube. Regardless of the location of the cutting mechanism, the first portion and the second portion may include a substantially triangular shape.

[0014] In one configuration, the cutting mechanism and the sealing mechanism form an integrated machine. The integrated machine may include a substantially "K" shape.

[0015] In one configuration, the cutting mechanism and the sealing mechanism cooperate to provide a sealed edge at the end wall that has a pair of legs extending from a cross member that joins the pair of legs, the legs extending from the cross member at an obtuse angle and away from one another. The cutting mechanism and the sealing mechanism may cooperate to provide a sealed edge at the end wall that has a substantially "U" shape.

[0016] In another configuration, a method is provided and includes rotatably supporting an elongated sheet of material defined by a plurality of material segments, drawing a left edge and a right edge of the elongated sheet of material together in an overlapping configuration around a forming tube to form the elongated sheet of material into a substantially tube shape, and sealing the left edge and the right edge of the elongated sheet of material to one another. The method also includes forming a gusseted tuck in each of a left sidewall panel portion of the substantially tube-shaped elongated sheet of material and a right sidewall panel portion of the substantially tube-shaped elongated sheet of material and removing by a cutting mechanism a first portion and a second portion of a first segment of the plurality of material segments in order to form a first cut and a second cut in the first segment. A sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall of the first segment with a substantially flat, rectangular-shaped footprint.

[0017] In one configuration, the method may additionally include severing by the cutting mechanism the first segment from a second segment located downstream from the first segment following formation of the end wall of the at first segment. The method may also include severing by the cutting mechanism the first segment at an opposite end of the first segment than the end wall following formation of the end wall to sever the first segment from a third segment located upstream from the first segment.

[0018] In one configuration, removing the first portion and the second portion includes removing the first portion and the second portion upstream from the forming tube. In another configuration, removing the first portion and the second portion includes removing the first portion and the second portion downstream from the forming tube.

[0019] In one configuration, removing the first portion and the second portion includes removing a substantially triangular shaped piece of material from the sheet of material.

[0020] In one configuration, the folding and sealing provides a sealed edge at the end wall that has a pair of legs extending from a cross member that joins the pair of legs. Providing the sealed edge having the pair of legs and the cross member includes extending the legs from the cross member at an obtuse angle and away from one another.

[0021] In one configuration, the folding and sealing provides a sealed edge at the end wall that has a substantially "U" shape.

[0022] In another configuration, a bag is provided and includes a front sidewall panel portion having a first end including a first cross member extending between and connecting a first edge and a second edge to provide the first end with a substantially "U" shape. The bag also includes a rear sidewall panel portion having a second end including a second cross member extending between and connecting a third edge and a fourth edge to provide the second end with a substantially "U" shape, whereby the second cross member is attached to the first cross member to create a first sealed joint between the front sidewall panel portion and the rear sidewall panel portion. A right sidewall panel portion extends between and connects the front sidewall panel portion and the rear sidewall panel portion at the first edge and the third edge to create a second sealed joint at a junction of the right sidewall panel portion and the first edge and a third sealed joint at a junction of the right sidewall panel portion and the third edge. A left sidewall panel portion extends between and connects the front sidewall panel portion and the rear sidewall panel portion at the second edge and the fourth edge to create a fourth sealed joint at a junction of the left sidewall panel portion and the second edge and a fifth sealed joint at a junction of the left sidewall panel portion and the fourth edge.

[0023] In one configuration, the front sidewall panel portion is folded at a location along a length of the first edge and the second edge to cause the first cross member to oppose a surface of the front sidewall panel portion. The first edge and the second edge may be deformed at the fold to maintain the folded nature of the first edge and the second edge. In one configuration, the first edge and the second edge receive the application of at least one of heat and pressure at the fold to maintain the folded nature of the first edge and the second edge.

[0024] In one configuration, the first edge and the second edge extend from the first cross member at an obtuse angle and in opposite directions from one another. Similarly, the third edge and the fourth edge also extend from the second cross member at an obtuse angle and in opposite directions from one another. In another configuration, the third edge and the fourth edge extend from the second cross member at an obtuse angle and in opposite directions from one another independent from the configuration of the first edge and the second edge.

[0025] In one configuration, the second sealed joint and the third sealed joint terminate at the first sealed joint. Similarly, the fourth sealed joint and the fifth sealed joint terminate at the first sealed joint. In so doing, the first sealed joint cooperates with the second sealed joint and the fourth sealed joint to provide the first end with a continuous, sealed joint extending along the first edge, the second edge, and the first cross member. Likewise, the first sealed joint cooperates with the third sealed joint and the fifth sealed joint to provide the second end with a continuous, sealed joint extending along the third edge, the fourth edge, and the second cross member.

DETAILED DESCRIPTION

[0075] A flat-bottom stand-up bag may be formed from an elongated sheet of material that is interfaced with a vertical form, fill, and seal (VFFS) system. The VFFS system may be utilized, for example, in the food production industry for depositing foodstuff (e.g., cereal, chips, popcorn, candy, nuts, or the like) into the flat-bottom stand-up bag. The VFFS system includes a finishing station that forms a lower end of the flat-bottom stand-up bag and may include at least one of, for example: (1) a gusseting mechanism for forming gussets along opposing sides of the flat-bottom stand-up bag; (2) a cutting mechanism that removes portions of material from the elongated sheet of material that forms the flat-bottom stand-up bag; and (3) a sealing mechanism that shapes and seals the lower end of the flat-bottom stand-up bag and an upper end of a subsequent flat-bottom stand-up bag.

[0076] Referring to FIG. 1A, in some implementations, a VFFS system 10 includes a plurality of connected components/stations 12-26. The plurality of connected

components/stations 12-26 include, for example: a support rod or spindle 12; a plurality of tensioners 14; a sheet guide 16; a vertically-arranged forming tube 18; a product delivery cylinder 20; a pair of spaced-apart drive belts 22; a vertical sealer 24; and a finishing station 26. The VFFS system 10 is shown in simplified form and does not illustrate, for example, one or more of: a supporting structure and an enclosure.

Therefore, even in the absence of illustrating the supporting structure and the enclosure, the above described plurality of connected components/stations 12-26 of the VFFS system 10 may be said to be connected to one another due to the fact that the above- described components 12-26 of the VFFS system 10 are connected to one or more of the not-illustrated supporting structure and the enclosure. Alternatively, the plurality of connected components/stations 12-26 of the VFFS system 10 may be said to be connected together, or are in communication with one another upon interfacing an elongated sheet of material S with the plurality of interconnected components/stations 12-26 of the VFFS system 10. The elongated sheet of material S may be, for example, a packaging film, such as: polypropylene; polyester; paper; polyolefin extrusions; adhesive laminates; and other such materials; or from layered combinations of the above. If the deposited material is foodstuff, the elongated sheet of material S may include an innermost metalized layer that assists in the retention of, for example, flavor of the foodstuff.

[0077] As seen in FIG. 1A, the elongated sheet of material S is initially arranged in the form of a wound roll that is rotatably supported on the support rod 12. The wound roll of the elongated sheet of material S is reeled off of the support rod 12 and subsequently interfaced with the remaining plurality of connected components/stations 12-26 of the VFFS system 10. As will be described, the VFFS system 10 spatially and physically manipulates the elongated sheet of material S from a first orientation in the form of a substantially planar sheet (as seen, for example, when the elongated sheet of material S is located about the plurality of tensioners 14) to a final orientation in the form of a three- dimensional end product defining a flat-bottom stand-up bag, B.

[0078] As seen in, for example, FIGS. 6, 7, and 8A-8D, the flat-bottom stand-up bag B is defined by an enclosed end wall EW having a substantially flat, rectangular-shaped footprint. The substantially flat, rectangular-shaped footprint assists in maintaining the flat-bottom stand-up bag B in an upright orientation, and, therefore inhibits the flat- bottom stand-up bag B from tipping over once the flat-bottom stand-up bag B is located upon a display shelf, for example. Further, the substantially flat, rectangular-shaped footprint also contributes to the formation of the flat-bottom stand-up bag B. In addition, the substantially flat, rectangular-shaped footprint also contributes to having a spatial geometry that inhibits an undesirable entrapment of the deposited material (e.g., foodstuff) between folds of material defining the flat-bottom stand-up bag B near the enclosed end wall EW of the flat-bottom stand-up bag, B. By preventing the entrapment of the deposited material between folds of material defining the flat-bottom stand-up bag B near the enclosed end wall, the flat-bottom stand-up bag B is further inhibited from tipping over once the flat-bottom stand-up bag B is located upon a display shelf or other flat surface.

[0079] Referring to FIG. 2, an exemplary elongated sheet of material S includes a plurality of segments Sp defined by, for example, a first segment Si a second segment S 2 a third segment S3 and an "n th " segment S n (where n is an integer greater or equal to 1 (n> 1) ). Although four segments (i.e., the first segment S| the second segment S 2 the third segment S3 and the "η Λ " segment S„) are shown and described at FIG.2, the elongated sheet of material S is exemplary and not limited to any particular number of segments. Portions of an exemplary segment of the plurality of segments Sp is described at FIG. 3.

[0080] As shown in FIG. 3, all of the material defining each segment Si//S 2 //S3//S n is utilized for forming the flat-bottom stand-up bag B except for a first substantially triangular cut section DCi (see also, e.g., FIG. 5B) and a second substantially triangular cut section DC 2 (see also, e.g., FIG. 5B). As shown in FIG. 5B, the first substantially triangular cut section DC| , and the second substantially triangular cut section DC 2 , are removed from each segment S|//S 2 //S3//S n during the manufacture of the flat-bottom stand-up bag B by the VFFS system 10.

[0081] With reference to FIG. 3, after forming the first substantially triangular cut section DCi and the second substantially triangular cut section DC 2 each segment Si//S 2 //S 3 //S n is defined by a length L and a width W. The width W is bound by a left edge EL and a right edge E . The length L is bound by a top edge Ετ and a bottom edge E B . As a result of the formation of the first cut section DQ and the second cut section DC 2 the bottom edge EB is defined by a left bottom edge portion EBL a middle bottom edge portion EB and a right bottom edge portion EBR.

[0082] The length L includes a first length segment LI a second length segment L2 and a third length segment L3. The first length segment LI is bound by the top edge E T and a first horizontal dashed line Hi that extends across the width, W. The second length segment L2 is bound by the first horizontal dashed line Hi and a second horizontal dashed line H 2 that extends across the width W. The third length segment L3 is bound by the second horizontal dashed line H 2 and the bottom edge EB. [0083] The first length segment LI defines a length of a plurality of sidewall panel portions SP of the flat-bottom stand-up bag B. A plurality of vertical dashed lines are shown extending across the length L in order to distinguish the plurality of sidewall panel portions SP of the flat-bottom stand-up bag B from one another. The plurality of sidewall panel portions SP may include, for example: a front sidewall panel portion SPF; a left sidewall panel portion SPL; a right sidewall panel portion SPR; a first half of a back sidewall panel portion SPBI; and a second half of the back sidewall panel portion SPB 2 .

[0084] The second length segment L2 generally defines a length of a plurality of bottom panel portions BP of the flat-bottom stand-up bag B. The plurality of dashed lines extending across the length L distinguishes the plurality of bottom panel portions BP of the flat-bottom stand-up bag B from one another. The plurality of bottom panel portions BP of the flat-bottom stand-up bag B may include, for example: a front bottom panel portion BPp; a left bottom panel portion BPL; a right bottom panel portion BPR; a first half of a back bottom panel portion BPBI; and a second half of the back bottom panel portion BP B2 .

[0085] The third length segment L3 generally defines a length of a plurality of horizontally sealable lip portions LH of the flat-bottom stand-up bag B. The plurality of horizontally sealable lip portions LH of the flat-bottom stand-up bag B include: a front horizontally sealable lip portion LHF; a first half of a back horizontally sealable lip portion LI½; and a second half of the back horizontally sealable lip portion L¾ 2 .

[0086] All of the length L and a first portion Wi of the width W extending from the left edge E L forms a first half a vertically-sealable lip portion LVi . All of the length L and a second portion W 2 of the width W extending from the right edge ER forms a second half of the vertically sealable lip portion LV 2 .

[0087] Referring back to FIG. 1A, an exemplary method (see also, e.g., 100 at FIG. 20) for utilizing the VFFS system 10 is described. In some implementations, the steps 101-106 of the method 100 are sequentially carried out in a successive order.

[0088] An elongated sheet of material S is rotatably supported at 101 on the support rod 12 and is arranged about the plurality of tensioners 14 in order to keep the elongated sheet of material S taught as the elongated sheet of material S is guided through the VFFS system 10. The plurality of tensioners 14 may be defined by at least, for example, a leading tensioner 14i and a trailing tensioner 14 7 . In some instances, the plurality of tensioners 14 may also include a plurality of intermediate tensioners 14 2 -146 arranged between the leading tensioner 14| and the trailing tensioner 14 7 . The elongated sheet of material S is passed from the trailing tensioner 14 7 for subsequent guiding over the sheet guide 16 and toward the vertically arranged forming tube 18 and the product delivery cylinder 20. As shown, there are seven tensioners 14|.14 7 , however, any number of tensioners 14|.14 7 may be used.

[0089] The sheet guide 16 directs the elongated sheet of material S into the vertically arranged forming tube 18 that is arranged around the product delivery cylinder 20. Once the elongated sheet of material S is directed into the vertically-arranged forming tube 18, the vertically-arranged forming tube 18 draws the left edge EL and the right edge ER of the elongated sheet of material S together in an overlapping configuration at 102 while also reconfiguring the spatial geometry of the elongated sheet of material S from a substantially planar shape (as seen, e.g., about the plurality of tensioners 14) to a substantially cylindrical or tube shape about the vertically-arranged forming tube 18. The pair of spaced-apart drive belts 22 is arranged in direct contact with the substantially cylindrical or tube-shaped elongated sheet of material S for advancing the substantially cylindrical or tube-shaped elongated sheet of material S along the vertically arranged forming tube 18 and away from a material depositing opening 28 of the product delivery cylinder 20.

[0090] As the substantially cylindrical or tube-shaped elongated sheet of material S is pulled downwardly by the pair of spaced-apart drive belts 22, the overlapping configuration of the left edge EL and the right edge ER of the elongated sheet of material S results in at least a portion of the first half of the vertically-sealable lip portion, LV|, to be arranged in an overlapped orientation with respect to at least a portion of the second half of the vertically-sealable lip portion LV 2 . Once the first half of the vertically sealable lip portion LV| is overlapped with the second half of the vertically sealable lip portion LV 2 the first half of the vertically sealable lip portion LVi is joined to the second half of the vertically sealable lip portion LV 2 by the vertical sealer 24 at 103.

[0091] After the first half of the vertically-sealable lip portion LVi is joined to the second half of the vertically-sealable lip portion LV 2 by the vertical sealer 24, the substantially cylindrical or tube-shaped elongated sheet of material S is advanced away from the vertical sealer 24 by the pair of spaced-apart drive belts 22 and toward the finishing station 26. Referring to FIGS. I B and 1C, the finishing station 26 may include one or more mechanisms 26a, 26b, and 26c for further spatially and physically manipulating the substantially cylindrical or tube-shaped elongated sheet of material S that will ultimately provide the substantially flat, rectangular-shaped footprint of the flat- bottom stand-up bag B. Some or all of the one or more mechanisms may be connected to one or more actuators A. The one or more actuators A may cause the one or more mechanisms 26a, 26b, 26c to be spatially manipulated relative to the sheet of material S in order to form the flat-bottom stand-up bag B. The one or more actuators A may be connected to a computing resource C. The computing resource C may send one or more periodic actuating signals to the one or more actuators A for causing movement of or actuating the one or more actuators A.

[0092] Referring to FIGS. 1 B and 4A-4C, in some implementations, the finishing station 26 includes a gusseting mechanism 26a defined by a first stationary gusseting rail 26ai and a second stationary gusseting rail 26a . The first stationary gusseting rail 26ai is spaced apart from the second stationary gusseting rail 26a 2 by a distance D thereby forming a gap G therebetween.

[0093] With reference to FIGS.1 B, 4A, and 4B, the drive belts 22 (shown in FIG. 1 A) advance the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the substantially cylindrical or tube-shaped elongated sheet of material S is drawn through the gap G between the first stationary gusseting rail 26ai and the second stationary gusseting rail 26a 2 . With reference to FIGS. 4B-4C, a spacing between the left sidewall panel portion SPL and the right sidewall panel portion SPR of the substantially cylindrical or tube-shaped elongated sheet of material S is defined by a geometry that is greater than the distance D between the first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 . Accordingly, the pair of stationary gusseting rails 26ai, 26a 2 cooperate to shape each of the left sidewall panel portion SPL of the substantially cylindrical or tube-shaped elongated sheet of material S and the right sidewall panel portion SPR of the substantially cylindrical or tube-shaped elongated sheet of material S to include a gusseted tuck T at 104 as the drive belts 22 advance the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[0094] Referring to FIG. 1C, in some instances, the gusseting mechanism 26a may alternatively include a first gusseting disk 26ai and a second gusseting disk 26a 2 that are spaced apart by a distance D, thereby forming a gap G therebetween. In some examples, the gusseting disks 26ai, 26a 2 may be spatially fixed in place. In other examples, each gusseting disk 26ai, 26a 2 may be permitted to rotate about an axis A-A (FIG. 9C) extending through an axial center of each gusseting disk 26ai, 26a 2 . The gusseting disks 26ai, 26a 2 may function in a substantially similar manner as described above with respect to the first stationary gusseting rail 26ai and the second stationary gusseting rail 26a 2 . If the gusseting disks 26ai, 26a 2 are permitted to rotate about respective axes A- A, the gusseting disks 26ai, 26a 2 may passively rotate about the respective axes A-A as the spaced-apart drive belts 22 advance the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[0095] Referring to FIGS. 5A and 5B, in some implementations, the finishing station 26 further includes a cutting mechanism 26b. As seen in FIGS. I B and 1C, the cutting mechanism 26b may include one or a pair of cutters 26b i, 26b 2 . The cutter or pair of cutters 26bi, 26b 2 may include, but is/are not limited to knives, scissors, punchers, die- cutters, shears, lasers, or the like. After the substantially cylindrical or tube-shaped elongated sheet of material S has been shaped to form the gusset tucks T as described above, the pair of spaced-apart drive belts 22 advances the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S interfaces with the cutting mechanism 26b. The cutting mechanism 26b removes the first portion DCi' and the second portion DC 2 ' of the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S in order to provide the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S with a first cut DC| and a second cut DC 2 at 105.

[0096] Referring to FIG. 6, the finishing station 26 further includes a sealing mechanism 26c. As seen in FIGS. IB and 1C, the sealing mechanism 26c may include a "K-shaped" sealing mechanism. The "K-shaped" sealing mechanism 26c provides the bag B with a sealed edge at the end wall (EW) that has a substantially "U" shape. In one configuration, the "U" shape includes two pairs of legs extending from a single cross member (i.e., sealed lip portion (LH)) that joins the legs. The legs extend from the cross member on both sides of the bag B such that a pair of legs are associated with the front bottom panel portion BP F and a pair of legs are associated with the back bottom panel portion BPBI and the back bottom panel portion BP B2 . Specifically, a first leg is formed at a sealed junction of the front bottom panel portion BPF and the left bottom panel portion BP L and a second leg is formed at a sealed junction of the front bottom panel portion BPF and the right bottom panel portion BPR. Similarly, a third leg is formed at a sealed junction of the back bottom panel portion BP B i and the left bottom panel portion BP L and a fourth leg is formed at a sealed junction of the back bottom panel portion BPB 2 and the right bottom panel portion BPR. [0097] Each of the legs terminate and are attached to the cross member (i.e., the sealed lip portion (LH)). Accordingly, when viewing the bag B from the from front sidewall panel portion SP F , the first leg, the second leg, and the cross member cooperate to provide a sealed edge having a substantially "U" shape. Similarly, when the bag B is viewed from the back sidewall panel portions SP B i, SP B2 , the third leg, the fourth leg, and the cross member cooperate to provide a sealed edge having a substantially "U" shape. In this configuration, the legs extend from the cross member at an obtuse angle and in a direction away from one another. The shape of the sealed edge is generally dictated by the " " shape of the sealing mechanism 26c, as shown in FIG. 9B.

[0098] Once the bag B is fully formed, the cross member is folded toward the front bottom panel portion BP F and is held in place by crimping the first leg and the second leg, as shown in FIG. 6. The crimp formed in the first leg and the second leg may be formed by folding the first leg and the second leg such that the cross member is brought into close proximity to the front bottom panel portion BP F . Once the cross member is in the desired position relative to the front bottom panel portion BP F , the first leg and the second leg may be locally deformed at the area of the fold via heat and/or pressure to maintain the folded nature of the first leg and the second leg. Folding the first leg and the second leg in this fashion provides the bag B with a substantially flat end wall (EW). While the first leg and the second leg are described as being folded, the third leg and the fourth leg could alternatively be folded such that the cross member is brought toward the back bottom panel portion BPBI and the back bottom panel portion BPB 2 .

[0099] After the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S has been shaped to include the first cut DC| and the second cutDC 2 , as described above, the pair of spaced-apart drive belts 22 advances the cut, gusseted, substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the cut, gusseted, substantially cylindrical or tube-shaped elongated sheet of material S interfaces with the sealing mechanism 26c. As seen in FIG. 6, the sealing mechanism 26c may spatially manipulate and seal the cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S at 106 by: (1 ) folding the bottom edge E B (see, e.g., FIG. 5B) of the cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S such that the front horizontally- sealable lip portion LH F overlaps with both of the first half of the back horizontal ly- sealable lip portion LHBI and the second half of the back horizontally-sealable lip portion LHB 2 ; and then (2) sealing the front horizontally-sealable lip portion LH F to both of the first half of the back horizontally-sealable lip portion LHBI and the second half of the back horizontally-sealable lip portion LHB 2 to thereby seal the plurality of horizontally- sealable lip portions LH and form the enclosed end wall EW.

[00100] Referring to FIG. 7, once the sealing mechanism 26c of the finishing station 26 folds and seals the cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S to form the enclosed end wall EW as described above, the VFFS system 10 is then subsequently actuated for passing foodstuff F (e.g., cereal, chips, popcorn, candy, nuts or the like) through the material depositing opening 28 of the product delivery cylinder 20 and then through the vertically-arranged forming tube 18 for subsequent arrival in a cavity formed by the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S. The enclosed end wall EW prevents the foodstuff F from escaping out of the cavity of the sealed, folded, cut, gusseted, substantially cylindrical, or tube-shaped elongated sheet of material S while the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S is still interfaced with the VFFS system 10.

[00101] Referring to FIGS. 1 A and 8A-8D, the pair of spaced-apart drive belts 22 may then advance the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) through the finishing station 26 such that the enclosed end wall EW of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is moved past the sealing mechanism 26c. Movement of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein), may cease once the top edge Ετ (as seen in, e.g., FIG. 8A) of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is arranged proximate the sealing mechanism 26c. Then, the sealing mechanism 26c may be actuated again for simultaneously sealing the top edge Ετ of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) while also simultaneously forming an enclosed end wall EW of the next segment of the plurality of segments SP reeled from the elongated sheet of material S. When the top edge Ετ of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein), is sealed as described above, a cutter may sever the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein), along the top edge ET to thereby provide the flat bottom stand-up bag B with the foodstuff F provided therein. The cutter may be incorporated into the sealer 26c such that the sealer 26c substantially simultaneously seals the top edge Ej of the bag B and severs the bag B from the adjacent bag being formed from the sheet of material S by the VFFS system 10.

[00102] Referring to FIG. 9A, an exemplary method (see also, e.g., 200 at FIG. 21) for utilizing a VFFS system 10' is described. In some implementations, the steps 201-206 of the method are sequentially carried out in successive order.

[00103] An elongated sheet of material S is rotatably supported on the support rod 12 at 201 and is arranged about the plurality of tensioners 14 in order to keep the elongated sheet of material S taught as the elongated sheet of material S is guided through the VFFS system 10'. The plurality of tensioners 14 may be defined by at least, for example, a leading tensioner 14] and a trailing tensioner 14 7 . In some instances, the plurality of tensioners 14 may also include a plurality of intermediate tensioners 14 2 -146 arranged between the leading tensioner 14j and the trailing tensioner 14 7 . The elongated sheet of material S is passed from the trailing tensioner 14 7 for subsequent guiding over the sheet guide 16 and toward the vertically arranged forming tube 18 and the product delivery cylinder 20.

[00104] The sheet guide 16 directs the elongated sheet of material S into the vertically arranged forming tube 18 that is arranged around the product delivery cylinder 20. Once the elongated sheet of material S is directed into the vertically-arranged forming tube 18, the vertically-arranged forming tube 18 draws the left edge EL and the right edge E R of the elongated sheet of material S together in an overlapping configuration while also reconfiguring the spatial geometry of the elongated sheet of material S from a substantially planar shape (as seen, e.g., about the plurality of tensioners 14) to a substantially cylindrical or tube shape about the vertically-arranged forming tube 18 at 203. The pair of spaced-apart drive belts 22 is arranged in direct contact with the substantially cylindrical or tube-shaped elongated sheet of material S for advancing the substantially cylindrical or tube-shaped elongated sheet of material S along the vertically arranged forming tube 18 and away from a material depositing opening 28 of the product delivery cylinder 20.

[00105] As the substantially cylindrical or tube-shaped elongated sheet of material S is pulled downwardly by the pair of spaced-apart drive belts 22, the overlapping configuration of the left edge E L and the right edge E R of the elongated sheet of material S results in at least a portion of the first half of the vertically-sealable lip portion LVi being arranged in an overlapped orientation with respect to at least a portion of the second half of the vertically-sealable lip portion LV 2 . Once the first half of the vertically sealable lip portion LV| is overlapped with the second half of the vertically sealable lip portion LV 2 , the first half of the vertically sealable Hp portion LV] is joined to the second half of the vertically sealable lip portion LV 2 by the vertical sealer 24 at 204.

[00106] After the first half of the vertically-sealable lip portion LVi is joined to the second half of the vertically-sealable lip portion LV 2 by the vertical sealer 24, the substantially cylindrical or tube-shaped elongated sheet of material S is advanced away from the vertical sealer 24 by the pair of spaced-apart drive belts 22 and toward the finishing station 26. Referring to FIGS. 9B-9C and 9D-9E, the finishing station 26 may include one or more mechanisms 26a, 26b, and 26c for further spatially and physically manipulating the substantially cylindrical or tube-shaped elongated sheet of material S that will ultimately provide the substantially flat, rectangular-shaped footprint of the flat- bottom stand-up bag B. Some or all of the one or more mechanisms may be connected to one or more actuators A. The one or more actuators A may cause the one or more mechanisms 26a, 26b, 26c to be spatially manipulated relative to the sheet of material S in order to form the flat-bottom stand-up bag B. The one or more actuators A may be connected to a computing resource C. The computing resource C may send one or more periodic actuating signals to the one or more actuators A for causing movement of or actuating the one or more actuators A.

[00107] Unlike the VFFS system 10 described above at FIG. 1 A, the VFSS system 10' is subtly different in that the finishing station 26 does not include the cutting mechanism 26b arranged proximate to the gusseting mechanism 26a and the sealing mechanism 26c. Rather, the cutting mechanism 26b (as seen, e.g., at FIG. 9B or 9C) of the VFFS system 10' provides the first cut DCi and the second cutDC 2 in the elongated sheet of material S at 202 after the elongated sheet of material S is reeled off of the support rod 12 and before the elongated sheet of material S is guided over the sheet guide 16 and toward the vertically-arranged forming tube 18 and the product delivery cylinder 20 for shaping the elongated sheet of material S into a tube shape. As a result, the elongated sheet of material S is formed to include the first cut DCi and the second cut DC 2 by the cutting mechanism 26b when the elongated sheet of material S in the form of a substantially planar sheet (as seen, for example, when the elongated sheet of material S is located about the plurality of tensioners 14) and not when the elongated sheet of material S has been formed into a substantially tube shape and gusseted as described above with respect to the VFFS system 10 of FIG. 1 A. As seen in FIGS. 9B and 9C, the cutting mechanism 26b may include one or a pair of punchers or die-cutters. Alternatively, the cutting mechanism 26b may include, but is/are not limited to knives, scissors, shears, lasers, or the like.

[00108] Referring to FIGS. l OA-l OC, in some implementations, the finishing station 26 includes a gusseting mechanism 26a defined by a first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 defining a pair of stationary gusseting rails 26a. The first stationary gusseting rail 26ai is spaced apart from the second stationary gusseting rail 26a 2 by a distance D thereby forming a gap G therebetween.

[00109] With reference to FIGS. 9B, 1 OA, and 10B, the pair of spaced-apart drive belts 22 advances the cut, substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the cut, substantially cylindrical or tube-shaped elongated sheet of material S is drawn through the gap G between the first stationary gusseting rail 26ai and the second stationary gusseting rail 26a 2 . With reference to FIGS. 10B- IOC, because a spacing between the left sidewall panel portion SPL and the right sidewall panel portion SPR of the cut, substantially cylindrical or tube-shaped elongated sheet of material S is defined by a geometry that is greater than the distance D between the first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 , the pair of stationary gusseting rails 26ai, 26a 2 shapes each of the left sidewall panel portion SPL of the cut, substantially cylindrical or tube-shaped elongated sheet of material S and the right sidewall panel portion SPR of the cut, substantially cylindrical or tube-shaped elongated sheet of material S to include a gusseted tuck T at 205 as the pair of spaced- apart drive belts 22 advances the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[00110] Referring to FIG. 9C, in some instances, the gusseting mechanism 26a may alternatively include a first gusseting disk 26ai and a second gusseting disk 26a 2 that are spaced apart by a distance D thereby forming a gap G therebetween. In some examples, the gusseting disks 26ai, 26a 2 may be spatially fixed in place. In other examples, each gusseting disk 26ai, 26a 2 may be permitted to rotate about an axis A-A extending through an axial center of each gusseting disk 26ai, 26a 2 . The gusseting disks 26ai, 26a 2 may function in a substantially similar manner as described above at FIGS. lOA-lOC with respect to the first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 . If the gusseting disks 26ai, 26a 2 are permitted to rotate about the axis A-A, the gusseting disks 26ai, 26a 2 may passively rotate about the axis A-A as the spaced-apart drive belts 22 advance the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[00111] Referring to FIG. 1 1, the finishing station 26 further includes a sealing mechanism 26c. As seen in FIGS. 9B and 9C, the sealing mechanism 26c may include a " -shaped" sealing mechanism.

[00112] After the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S has been shaped as described above, the drive belts 22 advance the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S is interfaced with the sealing mechanism 26c. The sealing mechanism 26c may spatially manipulate and seal the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S at 206 in a manner by: (1) folding the bottom edge EB of the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S such that the front horizontally-sealable lip portion LHF overlaps with both of the first half of the back horizontally-sealable lip portion LHBI and the second half of the back horizontally-sealable lip portion LHB 2 and then (2) sealing the front horizontally-sealable lip portion LHF to both of the first half of the back horizontally-sealable lip portion LHBI and the second half of the back horizontally-sealable lip portion LH B2 to thereby seal the plurality of horizontally-sealable lip portions LH and form the enclosed end wall EW.

[00113] Referring to FIG. 12, once the sealing mechanism 26c of the finishing station 26 folds and seals the gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S to form the enclosed end wall EW as described above, the VFFS system 10' is then subsequently actuated for passing foodstuff F (e.g., cereal, chips, popcorn, candy, nuts or the like) through the material depositing opening 28 of the product delivery cylinder 20 and then through the vertically-arranged forming tube 18 for subsequent arrival in a cavity formed by the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S. The enclosed end wall EW prevents the foodstuff F from escaping out of the cavity of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S while the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S is still interfaced with the VFFS system 10'.

[00114] Referring to FIGS. 9A, 13 A, and 13D, the pair of spaced-apart drive belts 22 may then advance the sealed, folded, gusseted and cut substantially cylindrical or tube- shaped elongated sheet of material S (including the foodstuff F deposited therein) through the finishing station 26 such that the enclosed end wall EW of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is moved past the sealing mechanism 26c. Movement of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) may cease once the top edge ET of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is arranged proximate the sealing mechanism 26c. Then, the sealing mechanism 26c may be actuated again for simultaneously sealing the top edge Εχ of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) while also simultaneously forming an enclosed end wall EW of the next segment of the plurality of segments Sp reeled from the elongated sheet of material S. When the top edge Εχ of the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is sealed as described above, the sealing mechanism 26c may also include a cutter that severs the sealed, folded, gusseted and cut substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein), along the top edge Εχ to thereby provide the flat bottom stand-up bag B with the foodstuff F provided therein.

[00115] Referring to FIG. 9D, another exemplary implementation of the VFFS system 10' including a gusseting mechanism 26a defined by a first stationary gusseting rail 26aj and a second stationary gusseting rail 26a 2 defining a pair of stationary gusseting rails 26a is described. The VFFS system 10' of FIG. 9D is substantially similar to the VFFS system 10' of FIG. 9B with the exception that the VFFS system 10' of FIG. 9D does not include a cutting mechanism (i.e., the finishing station 26 of the VFFS system 10' of FIG. 9D only includes the gusseting mechanism 26a and the sealing mechanism 26c). Because the VFFS system 10' of FIG. 9D does not include a cutting mechanism, the sheet of material S that is interfaced with the VFFS system 10' may be pre-cut in a manner to include at least one first cut DCi and at least one second cut DC 2 . As shown in FIG. 9C, the pre-cuts DCi, DC 2 formed in the sheet of material S may include a substantially triangular shape.

[00116] Referring to FIG. 9E, another exemplary implementation of the VFFS system 10' including a gusseting mechanism 26a defined by a first gusseting disk 26ai and a second gusseting disk 26a 2 defining a pair of gusseting disk 26a is described. The VFFS system 10' of FIG. 9D is substantially similar to the VFFS system 10' of FIG. 9B with the exception that the VFFS system 10' of FIG. 9D does not include a cutting mechanism (i.e., the finishing station 26 of the VFFS system 10' of FIG. 9D only includes the gusseting mechanism 26a and the sealing mechanism 26c). Because the VFFS system 10' of FIG. 9D does not include a cutting mechanism, the sheet of material S that is interfaced with the VFFS system 10' may be pre-cut in a manner to include at least one first cut DC] and at least one second cut DC 2 .

[00117] Referring to FIG. 14A, an exemplary method (see also, e.g., 300 at FIG. 22) for utilizing a VFFS system 10" is described. In some implementations, the steps 301- 305 of the method 300 are sequentially carried out in successive order.

[00118] An elongated sheet of material S is rotatably supported on the support rod 12 at 301 and is arranged about the plurality of tensioners 14 in order to keep the elongated sheet of material S taught as the elongated sheet of material S is guided through the VFFS system 10". The plurality of tensioners 14 may be defined by at least, for example, a leading tensioner 14| and a trailing tensioner 14 7 . In some instances, the plurality of tensioners 14 may also include a plurality of intermediate tensioners 14 2 -14e arranged between the leading tensioner 14| and the trailing tensioner 14 7 . The elongated sheet of material S is passed from the trailing tensioner 14 for subsequent guiding over the sheet guide 16 and toward the vertically arranged forming tube 18 and the product delivery cylinder 20.

[00119] The sheet guide 16 directs the elongated sheet of material S into the vertically arranged forming tube 18 that is arranged around the product delivery cylinder 20. Once the elongated sheet of material S is directed into the vertically-arranged forming tube 18, the vertically-arranged forming tube 18 draws the left edge EL and the right edge ER of the elongated sheet of material S together in an overlapping configuration while also reconfiguring the spatial geometry of the elongated sheet of material S from a

substantially planar shape (as seen, e.g., about the plurality of tensioners 14) to a substantially cylindrical or tube shape about the vertically-arranged forming tube 18 at 302. The pair of spaced-apart drive belts 22 is arranged in direct contact with the substantially cylindrical or tube-shaped elongated sheet of material S for advancing the substantially cylindrical or tube-shaped elongated sheet of material S along the vertically arranged forming tube 18 and away from a material depositing opening 28 of the product delivery cylinder 20. [00120] As the substantially cylindrical or tube-shaped elongated sheet of material S is pulled downwardly by the pair of spaced-apart drive belts 22, the overlapping configuration of the left edge EL and the right edge E R of the elongated sheet of material S results in at least a portion of the first half of the vertical ly-sealable lip portion LVi being arranged in an overlapped orientation with respect to at least a portion of the second half of the vertical ly-sealable lip portion LV 2 . Once the first half of the vertically sealable lip portion LVi is overlapped with the second half of the vertically sealable lip portion LV 2 the first half of the vertically sealable lip portion LVi is joined to the second half of the vertically sealable lip portion LV 2 by the vertical sealer 24 at 303.

[00121] After the first half of the vertically-sealable lip portion LVi is joined to the second half of the vertically-sealable lip portion LV 2 by the vertical sealer 24, the substantially cylindrical or tube-shaped elongated sheet of material S is advanced away from the vertical sealer 24 by the pair of spaced-apart drive belts 22 and toward the finishing station 26. Referring to FIGS. 14B and 14C, the finishing station 26 may include one or more mechanisms 26a, 26b, and 26c for further spatially and physically manipulating the substantially cylindrical or tube-shaped elongated sheet of material S that will ultimately provide the substantially flat, rectangular-shaped footprint of the flat- bottom stand-up bag B. Some or all of the one or more mechanisms may be connected to one or more actuators A. The one or more actuators A may cause the one or more mechanisms 26a, 26b, 26c to be spatially manipulated relative to the sheet of material S in order to form the flat-bottom stand-up bag B. The one or more actuators A may be connected to a computing resource C. The computing resource C may send one or more periodic actuating signals to the one or more actuators A for causing movement of or actuating the one or more actuators A.

[00122] Referring to FIGS. 14B and 15A-15C, in some implementations, the finishing station 26 includes a gusseting mechanism 26a defined by a first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 defining a pair of stationary gusseting rails 26a. The first stationary gusseting rail 26ai is spaced apart from the second stationary gusseting rail 26a 2 by a distance D, thereby forming a gap G therebetween.

[00123] With reference to FIGS. 14B, 15A, and 15B, the pair of spaced-apart drive belts 22 advances the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the substantially cylindrical or tube-shaped elongated sheet of material S is drawn through the gap G between the first stationary gusseting rail 26ai and the second stationary gusseting rail 26a 2 . With reference to FIGS. 15B-15C, because a spacing between the left sidewall panel portion SPL and the right sidewall panel portion SPR of the substantially cylindrical or tube-shaped elongated sheet of material S is defined by a geometry that is greater than the distance D between the first stationary gusseting rail 26& \ and a second stationary gusseting rail 26a 2 , the pair of stationary gusseting rails 26ai, 26a 2 shapes each of the left sidewall panel portion SPL of the substantially cylindrical or tube-shaped elongated sheet of material S and the right sidewall panel portion SPR of the substantially cylindrical or tube-shaped elongated sheet of material S to include a gusseted tuck T at 304 as the pair of spaced-apart drive belts 22 advances the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[00124] Referring to FIG. 14C, in some instances, the gusseting mechanism 26a may alternatively include a first gusseting disk 26ai and a second gusseting disk 26a 2 that are spaced apart by a distance D, thereby forming a gap G therebetween. In some examples, the gusseting disks 26ai, 26a 2 may be spatially fixed in place. In other examples, each gusseting disk 26ai, 26a 2 may be permitted to rotate about an axis A-A extending through an axial center of each gusseting disk 26ai, 26a 2 . The gusseting disks 26ai, 26a 2 may function in a substantially similar manner as described above with respect to the first stationary gusseting rail 26ai and a second stationary gusseting rail 26a 2 (FIGS. 15A- 15C). If the gusseting disks 26ai, 26a 2 are permitted to rotate about the axis A-A, the gusseting disks 26ai, 26a 2 may passively rotate about the axis A-A as the spaced-apart drive belts 22 advance the substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26.

[00125] Referring to FIGS. 16A and 1 B, in some implementations, the finishing station 26 further includes an integrated cutting and sealing mechanism 26b+26c. After the substantially cylindrical or tube-shaped elongated sheet of material S has been shaped to form the gusset tucks T as described above, the pair of spaced-apart drive belts 22 advances the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S through the finishing station 26 such that the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S is interfaced with the integrated cutting and sealing mechanism 26b+26c. The integrated cutting and sealing mechanism 26b+26c simultaneously removes a first portion DCV and a second portion DC 2 ' of the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S in order to form the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S to include a first cut DCi and a second cut DC 2 (as seen in FIGS. 16A-16B) while also sealing the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (as seen in FIG. 17) at 305.

[00126] The cutting component of the cutting and sealing mechanism 26b+26C may include, but is not limited to: one or more knives, one or more scissors, one or more punchers, one or more die-cutters, one or more shears, one or more lasers, or the like. As seen in FIGS. 14B and 14C, the cutting and sealing mechanism 26b+26c may include a " -shaped" sealing mechanism. Functionally, the sealing portion of the integrated cutting and sealing mechanism 26b+26c may spatially manipulate and seal the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S at 305 in a manner by: (1) folding the bottom edge EB (see, e.g., FIG. 16B) of the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S such that the front horizontal Iy- sealable lip portion LHF overlaps with both of the first half of the back horizontaily- sealable lip portion LHBI and the second half of the back horizontaily-sealable lip portion LHB 2 ; and then (2) sealing the front horizontaily-sealable lip portion LHF to both of the first half of the back horizontaily-sealable lip portion LHBI and the second half of the back horizontaily-sealable lip portion L¾ 2 to thereby seal the plurality of horizontaily- sealable lip portions LH and form the enclosed end wall EW.

[00127] Referring to FIG. 18, once the integrated cutting and sealing mechanism 26b+ 26c of the finishing station 26 simultaneously cuts, folds and seals 305 the gusseted, substantially cylindrical or tube-shaped elongated sheet of material S to form the enclosed end wall EW as described above, the VFFS system 10" is then subsequently actuated for passing foodstuff F (e.g., cereal, chips, popcorn, candy, nuts or the like) through the material depositing opening 28 of the product delivery cylinder 20 and then through the vertically-arranged forming tube 18 for subsequent arrival in a cavity formed by the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S. The enclosed end wall EW prevents the foodstuff F from escaping out of the cavity of the sealed, folded, cut, gusseted, substantially cylindrical, or tube-shaped elongated sheet of material S while the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S is still interfaced with the VFFS system 10".

[00128] Referring to FIGS. 14A and 19A-19D, the pair of spaced-apart drive belts 22 may then advance the sealed, folded, cut and gusseted, substantially cylindrical or tube- shaped elongated sheet of material S (including the foodstuff F deposited therein), through the finishing station 26 such that the enclosed end wall EW of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is moved past the integrated cutting and sealing mechanism 26b+26c. Movement of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein), may cease once the top edge Ετ of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is arranged proximate the integrated cutting and sealing mechanism 26b+26c. Then, the integrated cutting and sealing mechanism 26b+26c may be actuated again for simultaneously sealing the top edge Εχ of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) while also simultaneously forming an enclosed end wall EW of the next segment of the plurality of segments Sp reeled from the elongated sheet of material S. When the top edge Ej of the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) is sealed as described above, a cutter of the integrated cutting and sealing mechanism 26b+26c severs the sealed, folded, cut and gusseted, substantially cylindrical or tube-shaped elongated sheet of material S (including the foodstuff F deposited therein) along the top edge Ετ to thereby provide the flat bottom stand-up bag B with the foodstuff F provided therein.

[00129] A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other implementations are within the scope of the following claims. For example, the actions recited in the claims can be performed in a different order and still achieve desirable results.
