BACKGROUND

[0002] The present invention relates generally to a method of reducing label waste. The method is accomplished, in part, by using a portable, stand-alone cutting apparatus or a printer accessory cutting apparatus for cutting media, such as printed on media, to create on demand "kiss cut" or "die cut" like labels. Traditional methods of creating a pressure sensitive label matrix primarily involved either a die cutting or an etching or stenciling process with a blade or a laser. For example, die cutting is typically performed with either a flatbed or rotary mechanism, and involves the process of using a die to shear webs of low-strength material, such as pressure-sensitive label material.

Historically, die cutting began as a process of cutting leather for the shoe industry in the mid-19th century, but evolved over time and is now sophisticated enough to cut through just a single layer of a laminate, thereby making the process applicable to the production of labels, stamps, stickers, etc. When only the top layer of a laminate is to be cut, the die cutting operation is typically performed in a straight line and is known as "kiss cutting" because the cutting process does not disturb or cut through the laminate or label backing.

[0003] Unfortunately, there are a number of limitations associated with producing labels, such as pressure sensitive labels, via die cutting. For example, dies can be expensive to manufacture and maintain and require that the operator stock dies of various shapes, sizes and configurations to satisfy customer demand. For example, if a customer requires a label having unique shape, size or

configuration, the die operator may have to manufacture or purchase a special die to produce the labels to satisfy that particular customer, which can be both time consuming and expensive.

[0004] Further, printers used to create tags or labels typically employ a supply of tag stock that needs to be cut into individual units once printing is complete. A single roll of tag or supply stock can be sectioned into a large number of individual tags. Therefore, if in the middle of a production run with a particular die, a different size or shape of label is desired, production must be interrupted so that the die can be replaced with the desired die, which results in downtime and unwanted expense.

[0005] Additionally, the tag or supply stock used for many of these labels is constructed from plastic, vinyl, or FID supply material that is more difficult to cut than paper, and can lead to the creation of waste if the supply material is not cleanly cut by the cutting apparatus. Oftentimes, a cutting apparatus will be included with and attached to the printer so that the printing and cutting operations can be handled by a single device. While printers with integrated cutting devices give users the ability to print and cut in a single operation with one device, if either the printer or the cutting device breaks down or malfunctions, the entire integrated device may become unusable and result in significant production downtime and unwanted expense. Therefore, users sometimes prefer to have a separate, stand-alone cutting device that can be positioned downstream of a printer.

[0006] Additionally, other existing cutters used with printers to cut these types of materials suffer from other deficiencies or limitations. For example, circuit cutters are designed for cutting paper and cannot effectively cut plastic or other heavy duty stock. Stencil cutters designed for cutting vinyl stencils are similar to a single pen plotter, but with a stencil cutter holder, and an adjustable blade. Blades may have different cutter angles. However, testing with printer stock has shown that steeper profiles, such as an approximately 60 degree angle, catch the edge of the stock and jam the carriage of the printer or cutting device, which can lead to unnecessary label waste. Medium profiles, such as an approximately 45 degree angle, move over the edge of the stock, but bounce causing a perf cut for a short distance, which can also lead to unnecessary label waste and/or damage to the device. Lower profiles, such as an approximately 25 degree angle, move over the edge of the label stock, but the leading edge is not perfect which is most likely caused by cutter bounce from riding over the leading edge of the label stock. Additionally, edge damage tends to be an issue as this type of cutter moves into the stock if it is not positioned flat on the anvil.

[0007] While flatter blade angles generally ride more easily over the leading edge, any damage to the edge of the supply roll may still lead to jamming of the printer or cutting device and result in unnecessary label waste. Additionally, these types of cutters tend to wear quickly, which results in imperfect cuts to the stock over time and additional label waste, not to mention frequent downtime while the cutter is being repaired (e.g., sharpened) or replaced. Adhesive can also build up on the cutter blade or flow into the recently made cut, thereby exacerbating the problem. And, if the media being cut is not held under some tension, jamming of the printer or other device may occur. Blades with flatter cutting angles and the anvils that they cut against are also prone to early wear and failure. There are also limitations on speed that the cutter can travel without bouncing. Furthermore, it is unclear whether rotating this type of cutter 180° to turn and make a return cut will have an adverse impact on the overall life of the cutter, printer or other device, and/or the cut quality, which can also result in unnecessary label waste.

[0008] Consequently, there exists a long felt need in the art for a method of reducing label waste that utilizes a stand-alone or printer attached cutter device that can cut heavy or plastic tag stock cleanly and efficiently without jamming, and without excessive adhesive build-up on the cutter.

Additionally, there is a need for a stand-alone or printer attached cutter device that can create a cutting operation to simulate die cutting by cutting only the top layer or sheet of a laminate to enable a user to order and stock one base roll and generate, on demand, multiple labels of varying shapes, sizes and configurations therefrom.

[0009] The present invention discloses a method of reducing label waste that employs a unique stand-alone or printer attached cutting apparatus capable of cutting tag stock or base roll material made from plastic, vinyl, or FID supply material, in addition to normal and/or light weight tag or paper stock materials. The method of the present invention also discloses the use of a unique stand-alone or printer attached cutting apparatus capable of performing "kiss cuts" and other cuts resembling die cuts, without the disadvantages typically associated with the use of die cutters. In addition, the method of the present invention discloses unique user features to configure and maintain the cutting device and its various components to further reduce label and other waste in a safe and efficient manner.

[0010] The cutting apparatus used in the methods of the present invention may be a standalone device positioned downstream of a printer, such as those printers presently manufactured and sold by Avery Dennison ^® Corporation of Pasadena, California including the ADTP1 and ADTP2 tag cutting printers, or may be integrated with said printers, or may be used as a mobile device so that it can be moved to various different locations to work with an industrial printer or other combination.

SUMMARY

[0011] The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later. [0012] The subject matter disclosed and claimed herein, in one aspect thereof, comprises a method of reducing label waste that employs a stand-alone or printer attached cutting apparatus to cut or "kiss cut" media, such as printed on media. The cutting apparatus employed by the method of the present invention preferably comprises a housing, a cutter assembly, a carriage assembly, a drive element and a motor for powering the drive element.

[0013] In accordance with one embodiment, the method comprises the steps of: (a) providing a printer and a label material with an adhesive thereon; (b) providing a micro-processor for commanding said printer and configuring at least one cut of the label material; (c) providing a cutter apparatus; (d) implementing a first cut of the label material based on instructions received from the micro-processor; (e) advancing the label material; (f) implementing a second cut of the label material based on instructions received from the micro-processor; (g) further advancing the label material; and (h) dispensing a label from the label material.

[0014] In accordance with one embodiment, the cutter assembly, carriage assembly, drive element and motor are positioned at least partially within the housing. The housing may also comprise one or more electrical connections and/or data connections so that the cutter apparatus can take commands (via hardline or wireless) from the computer that is driving the printer, or the printer itself, as well as an entry port for receiving the stock material to be cut from, for example, a printer or other stock handling apparatus, and an exit port for discharging the cut stock media. In a further preferred embodiment of the present invention, the housing may also comprise a basket, positioned adjacent to and slightly beneath the exit port to catch and store the cut stock media until the user is ready to retrieve the same thereby preventing the same from becoming lost or damaged, which would also result in unnecessary label waste.

[0015] In one embodiment, the carriage assembly comprises a base element, a guide shaft, and a screw shaft, and the base element comprises a strike plate or anvil. The screw shaft moves the cutter assembly back and forth along the guide shaft, and across the media or stock being cut (i.e., cuts in both a forward and a backward direction). The cutter assembly further comprises a pressure adjusting element for adjusting the amount of force or pressure that the cutting element applies to the media or stock being cut. The cutting element may comprise a first bevel and a second bevel to better facilitate cutting in both back and forth directions as the cutter assembly moves back and forth across the stock media, and is also capable of making angled cuts or perpendicular cuts across the web, all while reducing the amount of label waste. [0016] In an alternative embodiment, the method may employ a carriage assembly that comprises a base element, a guide shaft, and a screw shaft, and the base element comprises a strike plate or anvil. The screw shaft moves the cutter assembly back and forth along the guide shaft, and across the media or stock being cut (i.e., cuts in both a forward and a backward direction). The cutter assembly further comprises a cutter carriage and an easily interchangeable cutter cartridge, wherein said cutter cartridge comprises a cut depth adjustment knob, a detent component, an eccentric pinion shaft, a bearer roller and a cutting element. The cutting element may comprise a first bevel and a second bevel to better facilitate cutting in both back and forth directions as the cutter assembly moves back and forth across the stock media, and is also capable of making angled cuts and perpendicular cuts across the web.

[0017] In one embodiment, the cutting force of the cutter assembly is not adjustable, but is of a fixed load as assembled, based on the amount of force to cut through the most severe or hardiest of allowable media. The cut depth is controlled by the diametric difference of an adjacent bearer roller to the cutter wheel, and can be further adjusted by the operator for additional control by means of a rotatable eccentric pinion shaft shared by both a bearer roller and the cutter wheel. If the device is attached to or incorporated into a printer, the cutting apparatus may also be configured to conform to the printer ribbon path to remain as close as possible to the print head.

[0018] In one embodiment of the present invention, the cutter mechanism and attaching covers may be configured to have a wide angled exit throat to facilitate the delamination and removal of newly cut labels or other materials from the liner carrier web. Additionally, the worm screw shaft may be positioned closer to the cutting wheel to oppose cutter forces to minimize long term wear, which could also result in unnecessary label waste. Further, the cutter carrier may be comprised of a Teflon- filled copolymer or similar material to reduce friction and wear on the device.

[0019] In another embodiment, the cutter wheel and depth controlling components are housed within a cartridge assembly that is easily installed and removed without the use of external tools, thereby decreasing overall downtime for the cutting apparatus and resulting in cost savings for the operator. Further, said components may be retained in position by the same component that apply the cutting pressure to the cutting wheel.

[0020] In one embodiment, additional cut depth may be controlled by rotating the common eccentric shaft that supports the cutter wheel and the bearer roller up to 90° in either a clockwise or a counter-clockwise direction. More specifically, the eccentric shaft is held in an indexed position by means of a detent component that is actuated by the same component that applies cutting pressure to the cutter cartridge and the cutter wheel.

[0021] In one embodiment of the present invention, cutting pressure may be attained by use of a single extension spring which rotates a pressure hub component about the worm screw shaft to result in direct line force downward onto the cutter cartridge and, ultimately, the cutter wheel. In another embodiment, the cutting anvil or plate, which is expected to be a wear item, may be screwed onto a mounting surface and configured symmetrically so as to be able to be reoriented 180° and/or flipped over. In this manner, the cutting anvil or plate could have up to four separate useful lives before having to be replaced, thereby resulting in cost savings to the operator and less downtime for the cutting apparatus.

[0022] To the accomplishment of the foregoing and related ends, certain illustrative aspects of the disclosed innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.

DETAILED DESCRIPTION

[0059] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.

[0060] The present invention discloses a method for reducing label waste that employs a standalone or printer attached apparatus that can quickly and cleanly cut or "kiss cut" a web of media stock 20, such as the face sheet of a paper laminate, vinyl or RFID stock material, in both a back and forth direction without damaging the cutting blade or the stock material, thereby reducing the amount of label waste typically associated with prior art cutting devices. Specifically, the cutting apparatus used in the method of the present invention can make "die cut" like cuts on stock 20 without suffering from the same structural and operational limitations of traditional die cutting devices.

[0061] Referring initially to the drawings, FIGS. 1-3 illustrate a stand-alone cutting apparatus

100 for use in accordance with the method of the present invention, though it is contemplated that a printer with an integrated cutting apparatus could also be used. The cutting apparatus 100 is used to cleanly and efficiently cut a supply stock 20 such as, but not limited to, paper, cardboard, laminated materials, plastic, vinyl, RFID supply, and the like, or any other material known to one of ordinary skill in the art that may accept printing, thereby resulting in a reduction of the label waste typically associated with prior art cutting devices. The supply stock 20 may be a heavy-weight, normal or light-weight stock material. [0062] As illustrated in FIGS. 1-3, the cutting apparatus 100 used with the method of the present invention is preferably a stand-alone device that can be positioned downstream of a printer to cut printed on supply stock 20 supplied by the printer. Nonetheless, it is contemplated that cutting apparatus 100 may also be integrated with a new or used printer device or adaptable as an accessory for connection to an outlet port of an existing table top, portable, or other type of ink jet, thermal, laser printer such as those currently manufactured and sold by Avery Dennison ^® Corporation of Pasadena, California, or used in wireless communication with said printer.

[0063] Cutting apparatus 100 is preferably comprised of a housing 101, a carriage assembly 102 and a repositionable cutter assembly 116 that is permitted to travel along a shaft, such as a screw shaft 114, as explained more fully below. Housing 101 may be generally cube-like in shape and is preferably comprised of a front panel 1010, a back panel 1012, opposing side panels 1014, a top 1016 and a bottom 1017, though other geometrical shapes are also contemplated without affecting the overall scope of the present invention. Although dimensions of the housing 101 (i.e., length, width, and height) are important design parameters, housing 101 may be any shape or size that ensures optimal performance during use and that minimizes space and/or footprint requirements.

[0064] Housing 101 may further comprise one or more electrical connections 1018 and/or hardline or wireless data connections 1019 so that cutting apparatus 100 can receive power from a power source such as an electrical outlet or battery pack (not shown) and send/receive commands from the computer or other device that is driving the printer, or the printer itself. Alternatively, cutter apparatus 100 may further comprise a computer microprocessor, memory and other well-known components to function as an independent stand-alone device, as generally illustrated in FIG. 11.

[0065] Back panel 1012 is preferably comprised of an opening or entry port 1013 for receiving the supply stock 20 to be cut by cutting apparatus 100, and may further comprise electrical connection 1018 and/or data connections 1019. Similarly, front panel 1010 is preferably comprised of an opening or exit port 1015 for discharging the cut supply stock 20 to the operator. Front panel 1010 may also comprise a basket or tray 103 positioned adjacent to and below exit port 1015 to receive the processed or cut supply stock 20 as it is discharged from cutting apparatus 100 via exit port 1015, and store the same for the user (not shown) to prevent the same from becoming damaged or lost, either of which would result in unnecessary label waste. Top 1016 may further comprise a user interface 105 that is in communication with the above described computer microprocessor to allow a user to command cutting apparatus 100 as a stand-alone device and without the assistance of a printer, as would be understood by one of ordinary skill in the art. Notwithstanding, it is also contemplated that said entry and exit ports 1013, 1015, respectively, user interface 105, electrical connections 1018, data connections 1019 and basket/tray 103 could be located elsewhere on housing 101 without affecting the overall concept of the present invention.

[0066] As illustrated in FIG. 4, the carriage assembly 102 preferably comprises a cutter bracket or base element 104 and a pair of side brackets 110 extending upwardly from said base element 104 for mounting to the respective interior side panels 1014 of housing 101. More specifically, each of the pair of side brackets 110 is attachable to a corresponding one of the side panels 1014 by any means commonly known in the art such as fasteners, tabs, etc.

[0067] As illustrated in FIGS. 4 and 9, the cutter bracket or base element 104 preferably cooperates with a mounting frame 106 and a strike plate 108, which functions as an anvil for a cutting element 134. The mounting frame 106 and the strike plate 108 may be integrated into a single unit, or the strike plate 108 may be separate and detachable for replacement due to wear or as otherwise needed. The base element 104 may be manufactured from aluminum, mild steel, or any other suitably hard material. The only potential limitation is that the material used to construct the base element 104 or, if applicable, strike plate 108 is preferably softer than the material used to construct the cutting element 134, to minimize wear and tear on cutting element 134. If the strike plate element 108 is detachable, the mounting frame 106 and a strike plate 108 may be manufactured from different materials to decrease cost. Ideally the strike plate 108 is positioned substantially adjacent to both the entry port 1013 and exit port 1015 so that as supply stock 20 is received by cutting apparatus 100 through entry port 1013 it automatically passes over strike plate 108 where it is sectioned into individual labels or tags by cutting element 134 that are then discharged from cutting apparatus 100 through exit port 1015 and fall into basket 103, where they may be stored until retrieved by the operator.

[0068] As illustrated in FIGS. 3, 4, 8 and 10, carriage assembly 102 further comprises a guide shaft 112 and a worm or screw shaft 114. The guide shaft 112 is a shaft such as, but not limited to, a high pitch linear shaft, capable of moving the cutter assembly 116 across the supply stock 20 in either direction (i.e., forwards or backwards) at production speeds. The guide shaft 112 spans the cutting apparatus 100 between sides of the cutter assembly cover and the pair of side brackets 110, and is located above strike plate 108 but below screw shaft 114.

[0069] Screw shaft 114 is typically a threaded rod such as, but not limited to, an acme thread, or any similar threaded rod capable of functioning as a worm screw. In one embodiment, screw shaft 114 may be a McMaster-Carr Ultra-Smooth Threaded Rod 6350K16 with a 3/8 ^th inch-5 thread, with a 5:1 speed ratio and a one inch travel/turn. Another embodiment may employ a 3/8-12 acme thread requiring twelve revolutions per inch of travel. The screw shaft 114 also spans the cutting apparatus 100 between the pair of side brackets 110 and is located above both the guide shaft 112 and the strike plate 108. One end of the screw shaft 114 may penetrate one of the pair of side brackets 110 so that it can engage a drive element 146 as illustrated in FIG. 3 and described infra.

[0070] As illustrated in FIGS. 5A and 8, cutter assembly 116 comprises cutting element 134, a guide element 118, a cutter holder 124, and a pressure adjusting element 130. The guide element 118 comprises a continuous guide shaft hole or opening 120 for receiving and engaging the guide shaft 112, and a continuous screw shaft hole or opening 122 located above the guide shaft hole/opening 120 for receiving and engaging screw shaft 114. The pressure adjusting element 130 may be a separate component, or may alternatively be integrated into a top of the guide element 118. The pressure adjusting element 130 comprises a plurality of adjusters 132 such as, but not limited to, screws, pins, rod and/or spring components, or any similar type of adjusting element known to one of ordinary skill in the art. The plurality of adjusters 132 enable the cutter holder 124 to be repositioned relative to pressure adjusting element 130 to adjust the distance therebetween. For example, in FIG. 5A, an operator may increase or decrease the distance by turning fastener 117 in a clockwise or

counterclockwise direction, respectively. Generally, the shorter the distance between cutter holder 124 and pressure adjusting element 130, the greater the pressure or force the cutting element 134 exerts on the supply stock 20 and the strike plate or anvil 108.

[0071] Cutter holder 124 comprises a guard portion 126 for retaining cutting element 134 and an axle 128 for rotatably holding cutting element 134 in place. The cutter holder 124 may be manufactured from any durable material, such as metal or plastic, and may be manufactured additively, by injection molding, or any other suitable manufacturing technique. Additionally, the cutter holder 124 may be detached from cutter assembly 116 so that a user can replace the entire cutter holder assembly (including cutting element 134) when, for example, cutting element 134 becomes dull or damaged, all without risk of injury. Alternatively, the cutting element 134 may be removed by itself for individual replacement or repair (e.g., sharpening), as desired.

[0072] As illustrated in FIGS. 5B, 6, and 7A-C, the cutting element 134 is typically a wheel knife that is retained by the cutter holder 124. The cutting element 134 may comprise a shaft hole 136, an inner lip 138, and a blade portion 140. The blade portion 140 may be inset within the guard portion 126 of the cutter holder 124 to protect both the operator and the sharp edge from being damaged. Cutting element 134 is easily replaceable, and may be manufactured from tool steel, carbide compounds, or any similar material known to one of ordinary skill in the art for use in cutting implements. When cutting the supply stock 20, the cutting element 134 presses against the stationary strike plate 108 of the carriage assembly 102 to completely sever the supply stock 20. Alternatively, pressure adjusting element 130 may be adjusted or manipulated so that cutting element 134 does not cut through the entire thickness of supply stock 20 (also known as a "kiss cut"), as may be desired by a user.

[0073] As best illustrated in FIG. 7C, blade portion 140 of cutting element 134 preferably comprises a first bevel 142. An angle of the first bevel 142 may vary based on the material and/or thickness of the supply stock 20 to be cut, and an operator can select an appropriate angle of bevel to administer the proper force necessary to cut the supply stock 20 cleanly and efficiently. While almost any angle may be used, most preferred embodiments of the present invention will employ bevel angles ranging from approximately 25 to approximately 60 degrees depending on the particular application.

[0074] As best shown in FIGS. 7A-B, blade portion 140 may further comprise a second bevel 144 with a similar angle to first bevel 142 to increase cutting efficiency when cutting in both back and forth directions. Additionally, the second bevel 144 may create a smaller contact point which reduces adhesive displacement on the stock supply 20 and improves blade life by keeping the blade portion 140 substantially free of adhesive buildup that may otherwise result from repeated contact with supply stock 20, and result in the dulling of blade 140.

[0075] Experimentation shows that supply stock 20 cut quality is generally equal in both cutting directions when using a carbide cutting element 134 with a pressure of approximately 5.4 Ib./in, or a tool steel cutting element 134 with a pressure of approximately 4.2 Ib./in. Testing with a 60 degree inclusive double bevel wheel knife also demonstrates that cutting spring force is approximately equal to 3.3 Ib./in; force for a 25 degree single bevel carbide wheel knife is approximately equal to 5.4 Ib./in; and force for a 25 degree single bevel tool steel 110895 is approximately equal to 5.4 Ib./in. Nonetheless, other pressures and bevel angles are also contemplated without affecting the overall concept of the present invention.

[0076] As best shown in FIG. 3, cutting apparatus 100 may further comprise a drive

element 146 and a motor 147 for operating drive element 146. Drive element 146 may be a belt, pulley, shaft, and the like, or any element capable of rotating screw shaft 114. Motor 147 is typically a stepper motor controlled by associated firmware, carriage sensor support, an independent PC board, and power support as generally illustrated in FIG. 11. Additional control may be exerted with fixed pressure settings, "C" type sensors or micro switches instead of mechanical switches, a lower turn bar, and a media tensioner. [0077] In a preferred embodiment of the present invention, motor 147 requirements and operating parameters for the screw driven concept may comprise one or more of the following: (i) a maximum peak torque to drive shaft at 5.8 Ib./in load in the cutter wheel is approximately equal to 12.3 oz./in; (ii) a minimum peak torque to drive shaft at 4.2 Ib./in load in the cutter wheel is

approximately equal to 8.75 oz./in; (iii) the full travel distance for a four inch wide media is

approximately 4.5 inches including ramp up and ramp down; (iv) 10T timing pulley on a threaded shaft; (v) 20T timing pulley on motor; (vi) cutter travel time on a test bed is approximately equal to a three second cycle with a two second cut time with a twelve revolution to one inch travel; and (vii) changing the wheel knife profile to a double bevel reduces cutter load force. Notwithstanding, the forgoing parameters are presented for illustrative purposes only and should not be construed as limitations as the cutting apparatus 100 of the present invention is contemplated to also operate in accordance with various other parameters.

[0078] As previously discussed, the cutting apparatus 100 of the present invention is used to cut or "kiss cut" supply stock 20. As illustrated in FIG. 12A, supply stock 20 may comprise a web or roll of the tag or label stock material that may be printed upon by a printer, and then cut by the cutting apparatus 100 into individual tags or labels. Additionally, supply stock 20 could be fed in a roll to roll matrix with an external liner take-up containing the cut label matrix. As illustrated in FIGS. 12A and 12B, the supply stock 20 may be cut into a portion 22 of the supply stock 20, such as a label. The cutting apparatus 100 may be designed to employ variable cuts on demand so that the portion of the supply stock 22 may vary in size and/or shape as desired. Further, the stand alone cutting apparatus 100 of the present invention may be used to make "kiss cuts", meaning that only the top layer of a label stock 20, such as a pressure sensitive label stock, may be cut, while the backing remains intact.

[0079] More specifically and as shown in FIG. 12B, supply stock 20 may comprise a top or face element 24, an adhesive element 26, and a liner element 28. The face element 24 may be manufactured from a thermal direct or thermal transfer paper, or any other suitable label material. The adhesive element 26 may be manufactured from a true cut adhesive designed not to flow into the area of a cut and is positioned or sandwiched between said face element 24 and liner element 28. The liner element 28 may be manufactured from a backer material such as, but not limited to, BG30, BG25, PET12, or the like. As illustrated in FIG. 13, and explained more fully below, the cutting apparatus 100 may be configured to cut the supply stock 20 to a depth that does not completely penetrate the supply stock 20. More specifically, pressure adjusting element 130 of cutting apparatus 100 may be configured to cut through face element 24 and adhesive element 26, but not into or through backing paper or liner element 28.

[0080] The continued description below relates to an alternative embodiment of the cutter assembly. Except as otherwise noted, the alternative embodiment of the cutter assembly of the present invention utilizes similar drive components except that the cutting pressure applied by said cutter assembly to supply stock 20 is not adjustable but rather is a fixed load as assembled, and the cutting depth is controlled by the diametric differences of the cutter wheel/blade and an adjacent bearer roller, as well as additional cutting depth controls that are adjustable by an operator.

[0081] Other differences between cutter assembly 116 and the alternative embodiment of the cutter assembly 424 are described more fully below and in FIGS. 14-29. While a number of said FIGS, depict alternative cutter assembly 424 as part of a printer, such as for example an ADTP1 or ADTP2 printer presently manufactured and sold by Avery Dennison Corporation of Pasadena, California, it should be appreciated that said FIGS, are for illustrative purposes only, and that alternative cutter assembly 424 may be used with cutting apparatus 100 as a stand-alone device and enclosed in housing 101, as described above with respect to cutter assembly 116.

[0082] More specifically, the cutting apparatus 100 comprises a carriage assembly 102. As in previous embodiments, the carriage assembly 102 comprises a base element 104, a guide shaft 112, and a screw shaft 114. The base element 104 comprises a mounting surface 106, such as a frame, and a strike plate 108. In the prior embodiments described above, the guide shaft 112 was positioned below the screw shaft 114, and downstream of a supply path of the supply stock 20. Additionally, in previous embodiments, the screw shaft 114 was positioned above the guide shaft 112, and was offset from the applied cutting forces of cutting apparatus 100.

[0083] However, in the alternative embodiment of the present invention, the locations of the guide shaft 112 and the screw shaft 114 are reversed so that the screw shaft 114 is positioned below the guide shaft 112. In this lower position, screw shaft 114 is closer and more normal (i.e., at an approximate right angle) to opposing cutting forces as practical, which minimizes cantilevered loads and reduces the potential for long term wear on the various moving components, while still permitting an operator easy and open access to cutting apparatus 100 to remove the cut or "kiss cut" labels. Further, in this particular embodiment, the upper guide shaft 112 is now positioned further away from screw shaft 114 to reduce the rotational load on the sliding guide features. Additionally, the cutting anvil or strike plate 108, which is typically considered a wear item, may be screwed or otherwise attached into position on the mounting surface 106 and configured symmetrically so as to be able to be reoriented 180° and/or flipped over. In this manner, the cutting anvil or strike plate 108 could have up to four separate useful lives before having to be replaced, thereby resulting in cost savings to the user and less downtime for the device and its operator.

[0084] Having described the general differences between other components of cutting apparatus 100 necessary to function with alternative cutter assembly 424, the actual cutter assembly will now be described in greater detail. FIGS. 14-18 all illustrate portions of cutter assembly 424 in the home position, and ready to receive cutting instructions and begin a cutting process. More specifically, FIG. 14 is an enlarged perspective view of a portion of cutter assembly 424, partially obstructed by a protective cover, and FIG. 15 illustrates an enlarged perspective side cross-sectional view of the cutter assembly 424. FIG. 16 illustrates a perspective rear view of cutter assembly 424 with the protective cover removed, and FIGS. 16-18 show a wide-angled exit opening of cutting apparatus 100 and cutter assembly 424, allowing for easy removal of a cut label from a supply stock 20. This also allows an operator easy access to install or load the supply stock 20 into cutting apparatus 100.

[0085] Cutter assembly 424 comprises a cutter carrier 426 and a removable cutter cartridge

438, each of which is described more fully below. Additionally, in this particular embodiment of the present invention and as best shown in FIGS. 16-18, the cutting apparatus 100 further comprises a cartridge release actuator 416 (also indicated by 412) comprising a cartridge release tab 418 and an actuator tab 420. The cartridge release actuator 416 (also indicated by 412) is preferably positioned on the "home" side of cutting apparatus 100 and outboard of cutter assembly 424, which is preferably located on the end of screw shaft 114 opposite that of drive element 146. Cartridge release actuator 416 (412) allows an operator to release and remove cutter cartridge 438 as an entire unit from the cutter carrier 426 of cutter assembly 424 without the need for external tools. More specifically, the operator actuates or presses the cartridge release tab 418 in a backward or counter-clockwise direction which, in turn, permits the cutter cartridge 438 to engage or disengage with the cutter assembly 424. In this manner, cutter assembly 424 can easily be repaired or replaced with minimal effort, risk of injury and/or downtime. As best illustrated in FIG. 18, cutting apparatus 100 may further comprise an optical interrupt sensor 422 and optical interrupt blades or ribs (not shown) on the cutter carrier 426 to allow appropriate sensing for motor control at the end of a cutting process.

[0086] The cutter carrier 426 is preferably manufactured from a low friction material, such as, but not limited to, a Teflon filled copolymer to reduce friction and wear of sliding contact surfaces in cooperation with the upper guide shaft 112. As illustrated in FIGS. 22 and 23, the cutter carrier 426 is positioned on an end of guide shaft 112, preferably opposite the side of drive element 146 and comprises a guide shaft hole or opening 428 for accepting and retaining guide shaft 112. The cutter carrier 426 further comprises a worm shaft hole or opening 430 and a worm screw nut 432. The worm shaft hole or opening 430 rotatably accepts the screw shaft 114, which is retained by the worm screw nut 432, as best shown in FIG. 15. The guide shaft opening 428 in this embodiment is located above the worm shaft opening 430. The cutter carrier 426 further comprises a cutter cartridge holder 434 for releasibly retaining the cutter cartridge 438. The cutter cartridge holder 434 may comprise a plurality of attachment points 436 such as diametric posts or hooks for cradling or supporting cutter cartridge 438.

[0087] Fig. 15 illustrates a cross-section of the cutting apparatus 100, and shows how a spring load is attained and applied to cutter cartridge 438. More specifically, cutting apparatus 100 further comprises a pressure hub 466 and a pressure adjusting element 472. The pressure adjusting element 472 is typically a single spring, such as a compression spring, as described supra. The single spring embodiment of the present invention frees up valuable space required for other component of the cutting apparatus 100 and is less complex to assemble and maintain. Additionally, the use of single spring 472 permits the guide shaft 112 and the screw shaft 114 to be repositioned in relation to the applied resistive forces, thereby avoiding cantilevered loading and decreasing wear on related moving components of cutting apparatus 100.

[0088] Cutting pressure is applied via the single extension spring 472 outboard of the guide shaft 112 and the screw shaft 114. As illustrated in FIG. 25, the pressure adjusting element/spring 472 is positioned between and attached to a cutter carrier attachment point 474 and a pressure hub attachment point 476, which is attached to or a part of pressure hub 466. The pressure hub 466 is rotatable about the end of screw shaft 114, and is retained by worm screw nut 432. Pressure hub 466 comprises a pressure exerting portion 468 and an actuator tab element 470. More specifically, the tension in extension spring 472 and the rotatable connection of pressure hub 466 about screw shaft 114 results in a downward force or pressure being applied by pressure exerting portion 468 onto a detent component 446 of cutter cartridge 438. This design results in a continuous, direct, in-line pressure being applied to cutting blade 462 of the cutter cartridge 438, while maintaining a compact, simple assembly. All load bearing components are in close proximity to each other and are configured to reduce long term wear, which could result in downtime and lost productivity.

[0089] FIGS. 16 and 17 illustrate the cutting apparatus 100 without covers, which includes a motor 147 and belt drive 146 arrangement for rotating screw shaft 114 in a manner similar to that which is described supra. Also specifically illustrated is how a counter-clockwise rotation of the cartridge release actuator 416, from a first position shown in FIG. 19 to a second position in FIG. 20, causes engagement with actuator tab element 470 on the rotatable cut pressure hub 466, which, in turn causes extension spring 472 to elongate. As spring 472 elongates and pressure hub 466 rotates about screw shaft 114 in a counter-clockwise direction, pressure exerting portion 468 disengages from detent component 446 of cutter cartridge 438 to keep it engaged with attachment points 436. With pressure no longer being applied to detent component 446 of cutter cartridge 438, cutter cartridge 438 can easily be removed and re-installed from the cutter carrier 426.

[0090] FIG. 19 illustrates pressure exerting portion 468 engaging, and applying pressure to, detent component 446 of cutter cartridge 438, thereby causing cutter cartridge 438 to be retained in said plurality of attachment points 436 of cutter carrier 426. FIG. 20 illustrates pressure exerting portion 468 disengaged from, and no longer applying pressure to, detent component 446 of cutter cartridge 438, thereby permitting cutter cartridge 438 to be removed from said plurality of attachment points 436 and cutter carrier 426.

[0091] FIG. 21 illustrates a perspective front view of the cutter assembly 424 with the release actuator 416 removed and the cutter cartridge 438 in an engaged position in the cutter carrier 426. FIG. 22 illustrates a perspective front view of the cutter assembly with the pressure hub 466 fully rotated, thereby releasing pressure on the cutter cartridge 438. With said pressure removed, cutter cartridge 438 is shown slid to a top of the retaining slots or the attachment points 436 of the cutter cartridge holder 434 as would be the case during installation or removal of the cutter cartridge 438.

[0092] FIG. 23 illustrates a perspective front view of the cutter assembly 424 with the release actuator 416 removed and the pressure hub rotated into the disengaged position, thereby allowing the cutter cartridge 438 to be displaced from the cutter carrier 426. It should be apparent that the four diametric posts of the cutter cartridge 438 align and engage with the four matching slots of the cutter cartridge holder 434 in the cutter carrier 426.

[0093] FIGS. 24 and 25 illustrate, among other things, an enlarged cross-sectional view of the cutter cartridge 438 and its various components. More specifically, cutter cartridge 438 comprises a housing 440, a pair of spaced apart grips or handles 442, a cut depth adjustment knob 444, detent component 446, a pinion shaft 448, a bearer roller 456, a plurality of bearings 458, a plurality of spacers 460, and a cutting blade 462.

[0094] Housing 440 is used to support the various components of cutter cartridge 438 and, as best illustrated in FIG. 23, one of said pair of grips 442 is positioned on each side of housing 440 to allow an operator to easily and securely handle cutter cartridge 438, for example, when installing and/or removing the same from cutter carrier 426. As best shown in FIGS. 19-23, rotatable cut depth adjustment knob 444 has a plurality of grooves or notches positioned around at least a portion of its circumference for engaging a pointed portion of detent component 446, and an indicator appearing on its face to permit the operator to adjust and keep track of the amount of its rotation, which represents depth of cut. More specifically, the slidably retained detent component 446 engages with a select one of said plurality of grooves of the cut depth adjustment knob 444 to retain the cut depth adjustment knob 444 in a specific and desired rotationally indexed position and, as described supra, the detent component 446 is held down in position by the pressure applied by the rotatable pressure hub 466 via pressure exerting portion 468. FIGS. 24-25 also illustrate how cut pressure is applied to the housing 440 and ultimately to the cutting blade 462 and the bearer roller 456, as well as applying pressure to retain the pointed end of the detent component 446 into indexed cooperation with a select groove in the cut depth adjusting knob 444.

[0095] Cut depth adjusting knob 444 may be rotated up to 90° in either a clockwise or counterclockwise direction. Rotation of cut depth adjusting knob 444, in turn, causes the eccentric pinion shaft 448 to rotate within housing 440. As best shown in FIGS. 24-25, eccentric pinion shaft 448 directly supports plurality of bearings 458 and plurality of spacers 460, and indirectly supports bearer roller 456 and cutting blade 462, as described more fully below.

[0096] FIG. 26 further illustrates eccentric pinion shaft 448, which comprises a pair of housing supports 450 positioned at the ends of eccentric pinion shaft 448, a bearer roller support 452 positioned adjacent to one of said housing supports 450, and a cutter wheel support 454 positioned adjacent to the opposite housing support 450. Further, a spacer or ridge R may be integrally formed in and extend outwardly from and around the circumference of eccentric pinion shaft 448, as shown in FIGS. 24-26, between said bearer roller support 452 and said cutter wheel support 454. Importantly, the pair of housing supports 450 and the bearer roller support 452 are concentrically aligned, but neither the housing supports nor the bearer roller support 452 are concentrically aligned with the cutter wheel support 454. Stated differently, the centerline of cutter wheel support 454 is eccentric or offset from the other sections of the eccentric pinion shaft 448, as explained more fully below.

[0097] As discussed supra and best illustrated in FIG. 24, at least one of said plurality of bearings 458 is positioned along eccentric pinion shaft 448 on each side of ridge R and over top of each of bearer roller support 452 and cutter wheel support 454. Further, at least one of said plurality of spacers 460 is also positioned along eccentric pinion shaft 448 adjacent to the outboard side of each of bearings 458, and immediately adjacent to each of said bearer roller support 452 and cutter wheel support 454. Cutter wheel or blade 462 may be any cutter known in the art, but is preferably similar to cutting element 134, as described supra. Cutter wheel 462 is positioned along eccentric pinion shaft 448 over top of bearing 458 which is, in turn, over top of cutter wheel support 454. Similarly, bearer roller 456 is positioned along eccentric pinion shaft 448 over top of bearing 458 which is, in turn, over top of bearer roller support 452. Additionally, bearer roller 456 is typically slightly smaller in diameter than cutting wheel 462, which nominally controls a fixed depth of cut. Additionally, because cutting wheel 462 is rotatably mounted on a bearing 458 that is, in turn, mounted on eccentric section of the pinion shaft 448, when pinion shaft 448 is rotated, cutting wheel 462 will be slightly higher (or lower) than the bearer roller 456, which provides an extended range of cutting depth adjustment to account for other variations in the supply stock thickness, stiffness, or other manufacturing variables.

[0098] FIG. 27 illustrates an end view of the eccentric pinion shaft 448 as viewed from the bearer roller support 452 side, and illustrates the offset relationship of a center 457 of the bearer roller 456 and the bearer roller support 452 versus a center 464 of the cutting wheel 462 and the cutter wheel support 454. It should be apparent to one of ordinary skill in the art that as eccentric pinion shaft 448 is rotated up to 90 degrees in either a clockwise or counterclockwise direction (by an operator turning or rotating cut depth adjusting knob 444) about the bearer roller center 457, the center 464 of the cutting blade 462 becomes vertically higher or lower than the center 457 of the bearer roller 452, as also illustrated in FIGS. 28-29. When held in a locked position by the cut depth adjustment knob 444 and the spring loaded detent component 446, this vertically higher or lower positional displacement of the cutting wheel center 464 can further adjust the depth of a cut of the cutting blade 462, which is being controlled by the adjacent bearer roller 456.

[0099] FIG. 28 illustrates the same relationship of offset centers 457 and 464 as described supra, but as viewed from the cutting blade 462 side of the eccentric pinion shaft 448. Further, FIG. 29 illustrates an enlarged end view of the offset centers 457 and 464 of the cutter wheel support 454 of the eccentric pinion shaft 448 and the bearer roller support 452 of the eccentric pinion shaft 448. It should be apparent that when rotating the eccentric pinion shaft 448 approximately between +90 degrees or - 90 degrees from the nominal position, the center of the cutter wheel support sections 454 becomes higher or lower than the bearer roller support section 452 of the eccentric pinion shaft 448, which will result in slightly deeper or shallower cutting of the supply stock 20.

[00100] As opposed to cutter assembly 116 discussed supra in which cut depth is controlled solely by the amount of cutting pressure applied which differs depending on stock thickness, stiffness, density, and blade wear, the cutting force of cutter assembly 424 is constant and not adjustable. Stated differently, the amount of force required to cut into the worst case or hardiest supply stock 20 is designed into the cutter assembly 424, and the nominal cut depth is controlled by the diameter differential of the cutting blade 462 and the bearer roller 456 of a slightly smaller diameter than the cutting blade 462 and runs adjacent to the cutting blade 462. Both the bearer roller 456 and the cutting blade 462 rotate on the eccentric pinion shaft 448, but the cutter wheel support section 454 is on an eccentric or offset center from the bearer roller support 452. This allows for further cut depth adjustment (plus or minus) by manually rotating the cut depth adjuster which, in turn, rotates the eccentric pinion shaft 448 such that the offset center of the cutting blade 462 becomes higher or lower than the controlling bearer roller 456. The rotatable pinion shaft 448 is indexed and retained in adjusted positions by an externally knurled or grooved knob (not shown) which is pressed into an end of the pinion shaft 448 and cooperates with the detent component 446 that is slidably retained within the cutter cartridge housing 440 and held in position by the same pressure hub 466 that applies the cutting pressure to the entire cutter assembly 424.

[00101] In summary, the cutter assembly 424 offers many distinct advantages including, without limitation, the following: (i) the cutter mechanism and attaching covers may be configured to have a wide angled exit throat to facilitate the delamination and removal of newly cut labels or other materials from the liner carrier web; (ii) the cutter wheel and depth controlling components are housed within a cartridge assembly that is easily installed and removed without the use of external tools, thereby decreasing downtime for the device and resulting in cost savings for the user; (iii) the cutter wheel and depth controlling components may be retained in position by the same component that apply the cutting pressure; (iv) cutting pressure may be attained by use of a single extension spring which rotates a pressure hub component about the worm screw shaft to result in direct line force downward onto the cutter cartridge; and (v) additional cut depth may be controlled by rotating the common eccentric shaft that supports the cutter wheel and the bearer roller.

[00102] Having described the various embodiments of the cutter apparatus, a method of using the cutter apparatus in the method of the present invention will now be described. Referring initially to the drawings, FIG. 30 is a flow chart of one embodiment of the method of reducing label waste of the present invention. More specifically, a printer and a label material are provided at step 200. The printer may be any printer known in the art capable of printing on supply stock, such as those printers presently manufactured and sold by Avery Dennison Corporation of Pasadena, California. Likewise, the label material may be any type of supply stock including, without limitation, those stock made from plastic, vinyl, or RFID supply material, in addition to normal and/or light weight tag stock materials, all of which are also presently manufactured and sold by Avery Dennison Corporation of Pasadena, California. [00103] At step 210, a computer micro-processor is provided for commanding said printer and configuring or laying out at least one cut of the label material. The computer microprocessor can be part of the printer, or, if a stand-alone cutting apparatus is being used, part of said stand-alone cutting apparatus, wholly independent of said printer or in communication with said printer.

[00104] At step 220, cutting apparatus 100 is provided and is used to implement a first cut of the label material based on instructions received from the above referenced microprocessor at step 230. As described above, during the first cut, cutting element 134 (or cutter wheel 462 in the alternative embodiment of the cutting apparatus) presses against the supply stock materials 20 positioned on stationary strike plate 108 of the carriage assembly 102 to completely sever the supply stock 20 into individual labels of a desired size, shape and configuration. Alternatively, pressure adjusting element 130 (or depth of cut adjustment knob 444 in the alternative embodiment of the cutting apparatus) may be adjusted or manipulated by an operator so that cutting element 134 (or cutter wheel 462 in the alternative embodiment of the cutting apparatus) does not cut through the entire thickness of supply stock 20 (i.e., a "kiss cut"), as may be desired by an operator.

[00105] Once the first cut has been completed, the label material or supply stock 20 is advanced through cutting apparatus 100 at step 240 so that a second cut may be implemented at step 250 based upon instructions received from the micro-processor. Similar to the first cut, during the second cut, the cutting element 134 (or cutter wheel 462 in the alternative embodiment of the cutting apparatus) presses against the previously cut supply stock 20 positioned on stationary strike plate 108 of the carriage assembly 102 to completely sever the supply stock 20. Alternatively, pressure adjusting element 130 (or depth of cut adjustment knob 444 in the alternative embodiment of the cutting apparatus) may be adjusted or manipulated by an operator so that cutting element 134 (or cutter wheel 462 in the alternative embodiment of the cutting apparatus) does not cut through the entire thickness of supply stock 20. Because cutting apparatus 100 is capable of making variable cuts, it is possible to vary the second cut from the first cut.

[00106] Following the completion of the second cut, the label material or supply stock 20 is again advanced through cutting apparatus 100 at step 260, and a cut label may be dispensed from the materials and cutting apparatus 100 at step 270. As described above, the unique configuration of cutting apparatus 100 and its various components, described supra, results in a reduction of label waste in comparison to prior art cutting devices.

[00107] FIG. 31 is a flow chart of an alternative and more streamlined embodiment of the method of reducing label waste of the present invention. More specifically, a label material or supply stock 20 with an adhesive thereon is provided at step 300. The label material may be any type of supply stock including, without limitation, those stock made from plastic, vinyl, or FID supply material, in addition to normal and/or light weight tag stock materials, all of which are presently manufactured and sold by Avery Dennison Corporation of Pasadena, California.

[00108] A cutter apparatus 100 is provided at step 310 and is comprised of carriage

assembly 102 and cutter assembly 116 (or cutter assembly 424 in the alternative embodiment). As mentioned above, cutter apparatus 100 can be a stand-alone device or mounted onto an existing printer as an accessory. At step 320, cutter assembly 116 implements a first cut of the label material. During said first cut, cutting element 134 of cutter assembly 116 (or cutter wheel 462 of cutter assembly 424 in the alternative embodiment of the cutting apparatus) presses against the supply stock 20 as it is positioned over stationary strike plate 108 of the carriage assembly 102 to completely sever the supply stock 20. Alternatively, pressure adjusting element 130 (or depth of cut adjustment knob 444 in the alternative embodiment of the cutting apparatus) may be adjusted or manipulated by an operator so that cutting element 134 (or cutter wheel 462 of cutter assembly 424 in the alternative embodiment of the cutting apparatus) does not cut through the entire thickness of the label material/supply stock 20. Following the first cut, the label material is advanced at step 330 without a substantial buildup of adhesive on cutting element 134 (or cutter wheel 462 in the alternative embodiment).

[00109] At step 340, cutter assembly 100 implements a second cut of the label material. Similar to the first cut, during the second cut, cutting element 134 of cutter assembly 116 (or cutter wheel 462 in the alternative embodiment) again presses against the stationary strike plate 108 of the carriage assembly 102 to completely sever the supply stock 20. Alternatively, pressure adjusting element 130 may be adjusted or manipulated so that cutting element 134 (or cutter wheel 462 in the alternative embodiment) does not cut through the entire thickness of the label material/supply stock 20. Following the second cut, a label may be dispensed from the label material at step 350 without a substantial buildup of adhesive on cutting element 134 (or cutter wheel 462 in the alternative embodiment).

[00110] FIG. 32 illustrates an alternative cut process flow chart, as controlled by a

microprocessor, in accordance with the disclosed architecture. More specifically, the process of cutting supply stock 20 using cutting apparatus 100 begins at 3310 when a cut command is received by a controller board at 3320. At 3330, the process determines if the knife or cutter is in the home position using sensors. The sensors may be mounted on the adjustable guide to control the cut width or, alternatively, the cut width can be controlled by the microprocessor. If the cutter is not in the home position, an error is detected at 3360 and the cut process terminates at 3375. [00111] If, on the other hand, it is determined that the cutter is in the home position at 3335, then the cutter may be driven inward at 3340 or outward at 3350 and, during the entire process, a busy signal is monitored by the microprocessor until the cutter is returned to the home position at 3365. If the cutter does not return to the home position as expected or the busy signal is removed before the home sensor is engaged, an error is detected at 3360 and the cut process terminates at 3375. If, on the other hand, the cutter is returned home at 3365 and the motor signal is low, the process was successfully completed and, at 3370, a cut count is incremented and the process exits at 3375.

[00112] What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term "includes" is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term "comprising" as "comprising" is interpreted when employed as a transitional word in a claim.
