Detailed Description

Figure 1 is a schematic drawing of an embodiment of an apparatus 1 for manufacturing an aerosol-generating consumable from a sheet of aerosol-generating material 2 according to a first embodiment. The manufacturing apparatus 1 includes cutting apparatus 3 for cutting the sheet of aerosol-generating material 2, prior to conveyance of the sheet of aerosol-generating material 2 into a consumable forming unit 4 of the manufacturing apparatus 1. In each embodiment of the invention, the sheet of aerosol-generating material 2 is a tobacco material, for example, a reconstituted tobacco material that is formed into a continuous web or sheet. However, it should be recognised that the aerosol-generating material 2 may alternatively be a non-tobacco based material.

The manufacturing apparatus 1 comprises a feeding apparatus 5 which mounts a spool or bobbin 7 of aerosol-generating material. The feeding apparatus 5 is configured to supply the sheet 2 of aerosol-generating material as a continuous sheet along a conveyance path 6. The sheet 2 maybe fed along the conveyance path 6 by any suitable mechanism, for example, a drive belt or a plurality of rollers (not shown), at least one of which is driven.

The consumable forming unit 4 of the manufacturing apparatus 1 is configured to receive the sheet 2 of aerosol-generating material as it is conveyed along the conveyance path 6. The consumable forming unit 4 is configured to form the sheet 2 into a consumable 8. In the present example, the consumable forming unit 4 is configured to gather or otherwise form the sheet 2 of aerosol-generating material into an elongate, continuous rod in rod-forming unit 9, and to wrap the continuous rod in wrapping materal in a wrapping unit 10 before subsequently cutting the elongate wrapped rod in a rod cutter 11, into discrete rod sections 8, each of which may form an individual consumable 8, as shown in Figure 1.

In some consumables, the sheet 2 is in the form of strips or strands that extend in a longitudinal direction along the length of the consumable 8 and in a direction that extends along the conveyance path 6 during manufacture. To enable this construction, it is known to cut the sheet 2 into a plurality of longitudinal strips or strands, which may be in the order of imm wide, using a cutting cylinder incorporating cutting blades which act on the sheet 2 and cut it prior to entry of the cut sheet into the consumable forming unit 4 that gathers and forms the strips into a rod and which wraps the rod in a wrapping material.

A problem with the aforementioned cutting technique is that a substantial amount of tobacco dust is produced. The dust coats or sticks to both the strands and the apparatus. Often, this problem is mitigated by providing a dust extraction system to either vaccum, or blow, the dust off the strands and the apparatus. However, this adds additional complexity to the apparatus and some dust will still remain. The dust may also be blown into the local area surrounding the apparatus. Another concern is that cutting blades provide a less than precise cut and, due to a lack of uniformity in the thickness of the sheet, can result in the snapping of individual strands. To alleviate or substantially overcome the aforementioned problems, the sheet 2 is cut into strips using a laser generator 3, which can provide a more precise and much cleaner cut, thereby avoiding or minimising dust. The likelihood of individual strands snapping or breaking is also prevented or reduced, as the strands maintain a greater tensile strength when cut by a laser emitted by a laser generator 3.

In an embodiment, the laser generator 3 is positioned above the aerosol-generating sheet 2 between the feeding apparatus 5 and the consumable forming unit 4 such that a laser emitted by the laser generator 3 will cut the sheet 2 of aerosol-generating material as it is conveyed along the conveyance path 6 and before it reaches the consumable forming unit 4. The laser generator 3 may be positioned so that the sheet 2 is cut into strands immediately after it is unwound from the bobbin 7 mounted on the feeding apparatus 5. Alternatively, the sheet 2 may be cut further downstream, i.e. just prior to entry into the consumable forming unit 4. A suitable laser generator is manufactured by Micro Laser Tech® 2 x 400W, model MLS-G 2-800 or MPS- M 4 - 800. .

The sheet 2 is cut into strands on-line, i.e. as the sheet 2 is unwound from the bobbin 7 and fed into the consumable forming unit 4 of a consumable manufacturing apparatus 1. However, it will be appreciated that the sheet 2 could also be pre-cut, i.e. the cuts in the sheet 2 could be formed as an integral part of the sheet manufacturing process. In this case, the manufactured sheet 2 is cut immediately after manufacture and before it is wound onto a bobbin 7 which is then subsequently mounted to the feeding unit 5 of the apparatus 1 for manufacturing the consumable. The sheet 2 is therefore wound onto the bobbin 7 in its cut form and the cutting apparatus comprising a laser generator 3 according to an embodiment of the invention can be located between the sheet manufacturing apparatus 1 and apparatus that winds the sheet onto a bobbin 7.

The sheet 2 may also be cut in an independent process on a dedicated cutting machine.

For example, an uncut sheet 2, which has been wound onto a spool 7 following manufacture, may subsequently be mounted to a cutting machine which unwinds the sheet from the spool 7, cuts it using a laser generator, before winding the cut sheet 2 back onto another spool 7. The laser generator 3 for cutting the sheet 2 may be mounted so that a laser generator cuts that portion of the sheet 2 which is between the two spools 7.

It will also be understood that, in an alternate embodiment, the feeding apparatus 5 can supply individual sheets of aerosol-generating material 2 along the conveyance path 6, with the laser generator 3 positioned so as to make cuts in each sheet, rather than in a continuous length of aerosol-generating material unwound from a bobbin 7.

The rod-forming unit 9 of the consumable forming unit 4 is configured to gather the sheet 2 of aerosol-generating material cut by the laser generator 3 and form them into a rod-like shape, which may have a generally circular shaped cross-section, although other cross-sectional shapes are envisaged. The rod-forming unit 9 may comprise a funnel or cone (not shown) that is configured to gather the strips together such that the strips exit the funnel or cone as a rod.

The wrapping unit 10 is downstream of the rod-forming unit 9, and is configured to wrap the gathered strips of aerosol-generating material in a wrapper. The wrapping unit may comprise a garniture (not shown) that is configured to receive the rod of gathered strips and wrap the strips in the wrapper. The wrapper may be fed as a continuous web through the garniture on a garniture belt (not shown) that is configured to wrap around the rod of strips as the belt, wrapper and strips pass through a narrowing cone or tongue of the garniture. The wrapper may then be secured in position using adhesive that is applied or pre-applied to an edge of the wrapper. The consumable forming apparatus 4 also comprises a rod cutter 11 located downstream of the wrapping unit 10. The rod cutter 11 is configured to cut the continuous wrapped rod into discrete rods 8 of aerosol-generating material. The discrete rods 8 produced by the rod cutter 11 may be single-length or double-length rods, or longer.

The laser generator 3 can have an array of laser generating heads mounted in a fixed position to simultaneously cut the sheet 2 into a plurality of strips as the sheet 2 is conveyed along the conveyance path 6 such that the strips extend in a direction along the conveyance path 6. However, one or more of the laser generating heads maybe movable so as to scan across the sheet 2. It is envisaged that the sheet 2 will continue to move along the conveyance path 6. However, it is also possible for the sheet 2 to move intermittently so that it is held stationary whilst being cut by the laser generator 3.

The apparatus 1 may include a control unit 12 operable to control activation of the laser generator 3. In some embodiments, such as that shown in Figure 1, the control unit 12 may control the laser generator 3 such that the laser generator 3 remains active in order to cut the sheet 2 continuously as the sheet 2 moves along the conveyance path 6. Figure 4A illustrates a plan view of a portion of a sheet 2 of aerosol-generating material which has been cut into a series of continuous, longitudinally extending parallel strips 13 by the laser generator 3 of Figure 1. In the drawing of Figure 3A, six cuts 14 have been made in the sheet to form five strips 13. However, it will be understood that the sheet 2 may be cut into any number of strips 13, and that it may be cut into strips 13 across the full width of the sheet 2. In a modified embodiment, the control unit 12 may be omitted altogether and the laser generator 3 maybe manually controlled, i.e. via an on/off switch, or it may operate in conjunction with operation of the feeding unit 5.

In an alternate embodiment, and as shown in the plan view of a portion of a sheet of aerosol-generating material 2 of Figure 4B, the control unit 12 may continuously activate and deactivate the laser generator 3 of Figure 1 as the sheet 2 continues to travel along the conveyance path 6, such that the sheet 2 is cut intermittently to form discrete cut sections 15 spaced from each other in a direction extending along the conveyance path 6. In Figure 4B, each discrete cut section 15 comprises four spaced, parallel, cuts 16 to form three strips 17. As with Figure 4A, each discrete cut section 15 may comprise any number of cuts 16 adjacent to each other and extending across the width of the sheet 2. A sheet 2 provided with discrete cut sections 15, such as those shown in Figure 4B, may be preferred if the sheet 2 is to be cut prior to it being wound onto a bobbin 7, as the intermittent cut sections 15 provide additional strength and maintain the overall integrity of the sheet 2 and make it easier to unwind when the bobbin 7 is mounted on the consumable manufacturing apparatus 1. If the sheet is pre- cut with discrete cut sections 15, the laser generator 3 may also be used to cut a registration mark 18 in the sheet 2 between or adjacent to the discrete cut sections 15, as shown in the plan view showing a portion of a sheet of aerosol-generating material 2 of Figure 4C. When the sheet 2 is subsequently unwound and fed along the conveyance path 6 into the consumable forming unit 4, additional cuts may be made in the web to form continuous longitudinal strips 13, so the sheet 2 appears as it does in Figure 4A. These additional cuts may be made using a laser generator 3 or, by a conventional cutting blade. Although the use of a conventional cutting blade will result in some dust being generated, the extent of the cuts that need to be made will be much shorter than the any cuts made to a previously uncut sheet, and so the amount of dust will be substantially reduced. Operation of the laser generator 3, or a conventional cutting blade, may be controlled in response to a signal received from a scanner 19 (see Figure 2) located upstream of the cutter and which reads the registration mark 18 on the sheet 2 and operates the cutter 3 to complete the cuts between the discrete cut sections 15.

The registration mark 18 may be a pattern or image that can be read by the scanner 19 on the manufacturing apparatus 1, and which is capable of sending a signal to control the cutter 3 to complete any cuts between the discrete cut sections 15 of the sheet 2 before the sheet 2 enters the consumable forming unit 4. The registration mark 18 may be formed using the laser 3 at reduced intensity so as not to penetrate all the way through the sheet 2, and/or used intermittently so as to form a series of perforations in the sheet 2.

In the illustrated embodiment of Figure 4C, the registration mark 18 is located between the discrete cut sections 15 and comprises a series of interlocking triangles, but the registration mark 18 can be formed from any individual shape or combination of shapes. The registration mark 18 can also be positioned elsewhere, i.e. adjacent to the discrete cut sections 15 or offset to one side of the region between the discrete cut sections 15.

As the sheet 2 travels along the conveyance path 6, the scanner 19 reads or recognises the registration mark 18 and sends a signal to the control unit 12 which then activates and deactivates a cutter, whether that be a laser generator 3 or a conventional cutting unit, to complete the cuts between the discrete cut sections 15 to form a plurality of continuous longitudinally extending strips, as shown in Figure 3A, before said strips enter the consumable forming unit 4.

In another embodiment, the discrete cut sections 15 and registration mark 18 may be cut into the sheet 2 using the laser generator 3, as shown in Figure 3, and there maybe no further cutting of the sheet 2 between the discrete cut sections 15 prior to entry of the sheet 2 into the rod forming unit 9. In this embodiment, the control unit 12 may instead be configured to control the rod cutter 11 that cuts the rod into discrete rods sections 8, in dependence on the signal received from the scanner 19 that reads the registration mark 18. In particular, the rod cutter 11 maybe controlled so that the rod is cut into discrete rod sections 8 so that a discrete cut section 15 extending from one end of each discrete rod section 8, and which forms a distal end of the consumable, i.e. the end of the consumable, opposite to a mouth end, which is inserted into an aerosolgenerating device 20 (see Figure 5) for heating the aerosol-generating material of the consumable during use. If the aerosol-generating sheet 2 is pre-cut with the discrete cut sections 15 and the registration mark 18, then the laser generator 3 may be omitted altogether from the embodiment shown in Figure 3. The scanner 19 then recognises the registration mark 19 and the control unit 12 controls the rod cutter 11 as described in the previous paragraph.

If the aerosol-generating device 20 (see Figure 5) into which the consumable 8 is inserted has a heating element 21 in the form of a pin or blade that is inserted into the distal end 22 of the consumable 8, the discrete cut section 15 extending from that end of the consumable 8 may facilitate the insertion of the heating element 21. The discrete cut section 15 may be the same length as the heating element 21 which is to be inserted to it. Alternatively, each discrete cut section 15 may be shorter or longer than the length of the heating element 21.

In the above embodiments, the scanner 19 may be arranged perpendicular to the conveyance path 4 or at an angle to the conveyance path 4 above the sheet of aerosolgenerating material 2. The scanner 19 may comprise a camera. Any suitable model of camera can be used, for example, the Keyence (TM) CA-HL02MX camera. A camera is configured to image the sheet 2 of aerosol-generating material as it passes along the conveyance path 4 and to detect the presence of a registration mark 18.

With further reference to Figure 5, the aerosol-generating device 20 is a noncombustible aerosol-generating device 20. An aerosol-generating system comprises a consumable 8 according to embodiments of the invention together with the aerosolgenerating device 20. As represented by the dashed lines in Figure 5, the aerosol- generating material 2 gathered into a rod and wrapped in wrapping material 23 has a discrete cut section 15 extending from the end of the consumable 8 that is inserted into the aerosol-generating device 20, such that the heater element 21 within the device 20 is received in the aerosol-generating material formed by the discrete cut section 15.

Referring now to Figure 6, a flowchart to illustrate a method 25 of manufacturing a consumable 8 for an aerosol-provision device 20 is illustrated. The method 25 comprises feeding a sheet of aerosol-generating material 2 along a conveyance path (step Si); cutting the sheet of aerosol-generating material 2 using a laser emitted by a laser generator 3 as the aerosol-generating sheet 2 is conveyed along the conveyance path (step S2), and forming the cut sheet 2 into a consumable 8 in a consumable forming unit 4 (step S3).

The step (step S2) of cutting the sheet of aerosol-generating material 2 using a laser generator 3 may comprise cutting it to form discrete cut sections 15 spaced from each other in a direction extending along the conveyance path 6, and so that each discrete cut section 15 comprises a plurality of parallel, elongate strips of aerosol-generating material 2.

The step of forming the cut sheet into a consumable 8 in a consumable forming unit 4 (step S3) may comprise forming the sheet 2 into a rod, wrapping the rod with a wrapping material and cutting the rod into discrete cut rods with a rod cutter 11.

The step of forming the cut sheet into a consumable 8 in the consumable forming unit 4 (step S3) may also comprise cutting the rod into discrete rods 8 using the rod cutter 11 such that a discrete cut section 15 extends from an end of each rod.

In some embodiments, the flavour comprises flavour components of cucumber, blueberry, citrus fruits and/or redberry. In some embodiments, the flavour comprises eugenol. In some embodiments, the flavour comprises flavour components extracted from tobacco. In some embodiments, the flavour comprises flavour components extracted from cannabis.

In some embodiments, the flavour may comprise a sensate, which is intended to achieve a somatosensorial sensation which are usually chemically induced and perceived by the stimulation of the fifth cranial nerve (trigeminal nerve), in addition to or in place of aroma or taste nerves, and these may include agents providing heating, cooling, tingling, numbing effect. A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucolyptol, WS-3. Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, contain an active substance and/ or flavourants. In some embodiments, the aerosol-generating material may comprise an “amorphous solid”, which may alternatively be referred to as a “monolithic solid” (i.e. non-fibrous). In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosol-generating material may for example comprise from about 50wt%, 6owt% or 70wt% of amorphous solid, to about 90wt%, 95wt% or ioowt% of amorphous solid. The aerosol-generating material 2 may be a laminate of 2 or more layers. One layer may be a gel layer and can include or be formed from a substance or flavourant such as menthol. The laminate may be formed as part of the bandcast process such that the laminate is wound onto a bobbin.

The aerosol-generating material may comprise one or more active substances and/or flavours, one or more aerosol-former materials, and optionally one or more other functional material. The aerosol-former material may comprise one or more constituents capable of forming an aerosol. In some embodiments, the aerosol-former material may comprise one or more of glycerine, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

The one or more other functional materials may comprise one or more of pH regulators, colouring agents, preservatives, binders, fillers, stabilizers, and/or antioxidants.

A consumable is an article comprising or consisting of aerosol-generating material, part or all of which is intended to be consumed during use by a user. A consumable may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generation area, a housing, a wrapper, a mouthpiece, a filter and/ or an aerosol-modifying agent. A consumable may also comprise an aerosol generator, such as a heater, that emits heat to cause the aerosol-generating material to generate aerosol in use. The heater may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor.

A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor maybe both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavour, acidity or another characteristic of the aerosol. The aerosolmodifying agent may be provided in an aerosol-modifying agent release component that is operable to selectively release the aerosol-modifying agent

The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.
