Definitions
- the present invention relates to a process for producing heat-not-burn device consumables comprising aerosol-generating material rod segments, and to heat-not-burn device consumables.
- tobacco leaves are shredded into short fine strips, also referred to as cut rag tobacco.
- the shredded tobacco is then dispersed over a continuous web of cigarette paper.
- a machine also known as a cigarette maker, folds the paper around the shredded tobacco to form a continuous rod.
- the rod is cut into segments of desired length.
- a filter is added to each tobacco rod segment to produce the cigarette.
- Smoking articles such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternatives to these articles by creating products that release compounds from tobacco or other materials without combusting. Examples of such products are so-called “heat not burn” products or tobacco heating devices or products or aerosol-generating devices or products, which release compounds by heating, but not burning, material, such as tobacco.
- EP 0 246 107 A2 discloses rods manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands.
- the strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod.
- the continuous rod is severed at regular intervals to provide a plurality of rods of the desired length.
- the resulting rods have a plurality of substantially longitudinally extending strands provided from the shredded sheet-like material.
- the rods are useful as cigarette rods or in the manufacture of cigarette filter elements.
- GB 1 234 786 A discloses a tobacco rod for a smoking product that incorporates a tobacco filler in the form of a bundle of longitudinally extending filaments of reconstituted tobacco surrounded by a tubular wrapper, each filament extending from end to end of the tobacco rod substantially parallel to the other filaments.
- the rod may be manufactured by guiding a bundle of reconstituted tobacco filaments to a garniture from which the loose bundle emerges as a tight cylindrical bundle. This bundle marries up with a web of cigarette paper from which a continuous rod is produced in a rod making device. The rod is cut into sections by a guillotine.
- US 5 025 814 A discloses filter rods for cigarette manufacture that include a plurality of strands of a reconstituted tobacco material.
- the tobacco material includes a sizing agent having a hydrophobic character.
- a rod having a circumference of about 24 mm can have about 320 strands of a sheet-like material cut at about 32 cuts per inch. The strands extend along the longitude of the rod.
- the filter elements provided from the rods provide a useful mouthpiece for cigarettes and also impart a unique tobacco taste.
- a process of producing heat-not-burn device consumables wherein the heat-not-burn device consumables comprise aerosol-generating material rod segments, comprising: cutting a sheet of aerosol-generating material longitudinally to produce a plurality of aerosol-generating material strands; gathering the strands together to form an aerosol-generating material rod in which each of the plurality of aerosol-generating material strands is substantially non-coiled; and cutting the aerosol-generating material rod into segments to produce said aerosol-generating material rod segments.

- the process may comprise: selecting a mass per unit length for the aerosol-generating material rod segments; determining, based on a mass per unit area of the sheet of aerosol-generating material, and based on the selected mass per unit length for the aerosol-generating material rod segments, a bobbin width; and slitting the mother reel to produce a bobbin having the determined bobbin width.
- the process may comprise: selecting a strand number and/or a strand width for the aerosol-generating material rod segments; and determining, based on the selected strand number and/or strand width, a cut number and/or a cut spacing; and the cutting the sheet of aerosol-generating material may comprise cutting the sheet of aerosol-generating material with the determined cut number and/or cut spacing.
- the process may comprise: feeding the sheet of aerosol-generating material in a sheet feed direction; and the cutting the sheet of aerosol-generating material may comprises cutting the sheet of aerosol-generating material substantially parallel to the sheet feed direction.
- the gathering may comprise: gathering each of the strands towards an axis that lies in a plane, the plane including the feed direction and being perpendicular to a plane defined by the plurality of strands before they are gathered.
- the gathering may comprise: gathering each of the strands towards an axis that lies centrally of the plurality of strands.
- the gathering may comprise: gathering each of the strands substantially transversely to form the rod.
- the gathering may comprise: feeding the strands through a funnel to gather the strands.
- the process may comprise, before said cutting the sheet of aerosol-generating material: feeding the sheet of aerosol-generating material through the funnel to form an aerosol-generating material rod of non-cut tobacco sheet.
- Each of the plurality of strands may have a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm.
- the process may comprise: wrapping the aerosol-generating material rod in a wrapping material.
- the wrapping material may be or comprise one or both of paper and aluminium foil.

- the heat-not-burn device consumable may be a consumable for an aerosol-generating device.
- the first cutter 106 is arranged to cut a tobacco sheet 104 longitudinally to produce a plurality of tobacco strands 112.
- the gatherer 114 is arranged to gather the strands 112 together to form a tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially non-coiled.
- the second cutter 124 is arranged to cut the tobacco rod 120 into segments to produce tobacco rod segments 126.
- the gatherer 114 being arranged to gather the strands 112 together to form a tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially non-coiled allows for the production of a number of tobacco rod segments 126 into which a blade type heater of an aerosol generating device may be readily inserted (see e.g. Figures 5a and 5b ), in use, and which facilitates transport of volatile materials therethrough thereby reducing losses of volatile materials when the tobacco rod segment 126 is heated.
- the first cutter 106 is arranged to cut the tobacco sheet 104.
- the tobacco sheet 104 may be a sheet or web of reconstituted tobacco.
- Reconstituted tobacco sheets may be produced, for example, by a paper making process, band casting or extrusion.
- the reconstituted tobacco sheet may be paper reconstituted tobacco.
- Paper reconstituted tobacco refers to tobacco material formed by a process in which tobacco feedstock is extracted with a solvent to afford an extract of solubles and a residue comprising fibrous material, and then the extract (usually after concentration, and optionally after further processing) is recombined with fibrous material from the residue (usually after refining of the fibrous material, and optionally with the addition of a portion of non-tobacco fibres) by deposition of the extract onto the fibrous material.
- the process of recombination resembles the process for making paper.
- the feedstock may comprise or consist of one or more of tobacco strips, tobacco stems, and/or whole leaf tobacco. Scraps, fines and winnowings may alternatively or additionally be employed in the feedstock. It will be appreciated that reconstituted tobacco sheet 104 formed by any process may be used.
- the reconstituted tobacco sheet 104 is malleable.
- the tobacco sheet 104 may be provided from a bobbin 102 of tobacco sheet 104.
- the bobbin 102 comprises a spindle 102a around which continuous tobacco sheet 104 is wound.
- the bobbin 102 is arranged to rotate to feed the tobacco sheet 104 from the bobbin 102 to the first cutter 106 along a sheet feed direction (arrow A).
- the apparatus 100 may be arranged to drive the bobbin 102 to rotate.
- the bobbin 102 may be free to rotate, and the tobacco sheet 104 being pulled from the bobbin 102 by a downstream component of the apparatus, for example a roller or drive belt (not shown in Figure 1 ) may cause the bobbin to rotate.
- the tobacco sheet 104 may comprise glycerol.
- the reconstituted tobacco sheet 104 may be impregnated or otherwise formed with glycerol.
- the glycerol When heated, the glycerol may be volatilised to form an aerosol, which may enhance user experience of an aerosol-generating device, or any suitable "heat not burn" device, with which the tobacco rod segment 126 may be used.
- the tobacco sheet 104 is of known dimensions.
- the width and thickness of the tobacco sheet 104 fed from the bobbin 102 may be constant and known.
- the tobacco sheet 104 may be of a given and constant mass per unit length. This may ensure that the tobacco rod segments 126 produced are of consistent weight per unit length. Using a tobacco sheet 104 of known (and constant) dimensions therefore allows weight control of the resulting tobacco rod segments 126 without the need for weighing systems for weighing the tobacco rod 120 or tobacco rod segments 126.
- the first cutter 106 is arranged to cut the tobacco sheet 104 longitudinally to produce a plurality of tobacco strands 112.
- the tobacco strands 112 produced are elongate.
- the first cutter 106 comprises a cutter array 106a.
- the cutter array 106a comprises a plurality of circular discs 108 arranged along an axle 110.
- the discs 108 each have sharpened edges.
- the axle 110 is arranged substantially perpendicularly to the sheet feed direction (arrow A), and each disc 108 is arranged such that the cutting edge of the disc 108 runs substantially parallel to the sheet feed direction (arrow A).
- Each disc 108 is arranged to cut the tobacco sheet 104 longitudinally i.e. to cut the tobacco sheet 104 along its length, as the tobacco sheet 104 is fed through the first cutter 106.
- the cutter array 106a may cut the tobacco sheet 104 against a support surface (not shown) arranged on an opposite side of the tobacco sheet 104 to the cutter array 106a.
- the plurality of discs 108 act to cut the tobacco sheet 104 into a plurality of substantially parallel elongate tobacco strands 112.
- the number of tobacco strands 112 produced depends on the number of cutting discs 108 the cutter array 106a comprises. For example, a cutter array 106a comprising eight cutting discs 108 will produce a total of nine tobacco strands. In general, a cutter array 106a comprising n cutting discs 108 will produce n+1 tobacco strands 112.
- the strand width of the tobacco strands 112 depends on the spacing between consecutive ones of the cutting discs 108.
- the discs 108 are equally spaced along the length of the axle 110, and along the width of the tobacco sheet 104, so that each of the elongate tobacco strands 112 is of substantially equal width. This arrangement may help to ensure consistency of the tobacco rod segments 126 produced.
- the cutter array 106a may be arranged such that each of the plurality of elongate tobacco strands 112 has a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm. This would correspond, for example, to the cutting discs 108 being spaced apart by substantially 0.25 mm to 3 mm, or substantially 0.5 mm to 1.5 mm, respectively.
- the first cutter 106 may be adjustable so as to adjust the number and/or width of the strands 112 into which the tobacco sheet 104 is cut.
- the cutting discs 108 may be adjustable on the axle 110 to adjust the number of discs 108 on the axle and/or to adjust the spacing between each disc 108 along the axle 110.
- the cutter array 106a may be replaceable by another cutter array 106a having a different number of discs 108 and/or different spacing between the discs 108. This allows flexibility in the number and/or width of the strands 112 in the tobacco rod segments 126 produced, and hence flexibility in the characteristics of those tobacco rod segments 126.
- the gatherer 114 is arranged to gather the plurality of tobacco strands 112 together to form a tobacco rod 120.
- the gatherer 114 is a funnel 114.
- the funnel 114 comprises a funnel portion 116 and a stem portion 118.
- the funnel portion 116 and the stem portion 118 are circular in cross-section, and are coaxial.
- the funnel 114 is symmetric about its axis.
- the funnel portion 116 narrows from a relatively wide mouth 116a to the relatively narrow stem portion 118.
- the tobacco strands 112 travel through the funnel 114 from the funnel portion 116 to the stem portion 118.
- the narrowing diameter of the funnel portion 116 gathers the strands 112 together to form the tobacco rod 120.
- the funnel 114 is aligned with and positioned centrally of the plurality of tobacco strands 112.
- the funnel 114 therefore gathers each of the strands 112 substantially transversely to form the rod 120.
- the funnel 114 gathers each of the strands 112 towards an axis that lies centrally of the plurality of strands 112.
- the funnel 114 being aligned with the tobacco strands 112 in this way may allow the strands 112 to be gathered evenly and centrally of the funnel 114.
- the funnel 114 is aligned with and positioned centrally of the tobacco sheet 104. Specifically, the axis towards which the strands 112 are gathered by the funnel 114 lies in a first plane, the first plane including the feed direction (arrow A) and being perpendicular to a second plane defined by the plurality of strands 112 before they are gathered. This alignment may help ensure an even tension across the plurality of strands 112 as they are gathered by the funnel 114.
- the funnel 114 applies substantially transverse forces to the strands 112 as they pass through the funnel 114, which transverse forces are directed substantially centrally of the plurality of strands 112.
- the tobacco strands 112 are not coiled as they are gathered, i.e. remain substantially non-coiled as they are gathered (i.e. during the gathering), i.e. as they pass through the funnel 114.
- the tobacco strands 112 are not twisted, spiralled, rolled or intertwined relative to one another as they are gathered, for example they do not form a twisted or spiralled or helical structure or shape as they are gathered.
- the funnel 114 therefore gathers the strands 112 together to form the tobacco rod 120 in which each of the plurality of tobacco strands 112 are substantially non-coiled.
- the tobacco strands 112 remain substantially parallel to one another as they are gathered, i.e. as they pass through the funnel 114.
- the funnel 114 therefore gathers the strands 112 together to form the tobacco rod 120 in which the plurality of tobacco strands 112 are substantially parallel to one another.
- the tobacco strands 112 are not substantially bent, corrugated, crimped or deformed or the like as they are gathered, and remain substantially straight as they are gathered, i.e. as they pass through the funnel 114.
- the funnel 114 therefore gathers the strands 112 together to form the tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially straight.
- the apparatus 100 comprises a wrapper 122 arranged to wrap the tobacco rod 120 in a wrapping material 128.
- the wrapper 122 may be, for example, the same as or similar to the wrapper 222 described below with reference to Figure 2 .
- the wrapper 122 wraps a continuous sheet of wrapping material 128 around a circumference of the continuous tobacco rod 120, and applies adhesive to the wrapping material 128 to seal the wrapping material 128 in place around the rod 120.
- the wrapping material may be or comprise, for example, one or both of paper and aluminium foil.
- the wrapping material may be a laminate of aluminium foil and paper. This laminate may help prevent ignition of the tobacco rod segment 126, which may be useful for example where the tobacco rod segment 126 is for use as a consumable in a "heat not burn" device, or a tobacco heating product device, or an aerosol-generating device.
- the outer diameter of the tobacco rod 120 once wrapped may depend, for example, on the mass per unit length of the tobacco sheet 104 used, the thickness and width of the tobacco sheet 104 used, the level of compression in the garniture during rod forming, and/or for example properties of the wrapper 122 and/or wrapping material 128 used.
- the outer diameter of the wrapped tobacco rod 120 may be constant during a given operational cycle of the apparatus 100.
- the outer diameter may be substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm, for example.

- the second cutter 124 cuts through the tobacco rod 120 transversely, so as to produce lengths of tobacco rod 120 (i.e. the tobacco rod segments 126.
- the second cutter 124 may comprise, for example, a blade (not shown) whose cutting surface (not shown) is arranged perpendicularly to the length of the tobacco rod 120, and is controllable to slice through the tobacco rod 120.
- the tobacco sheet 104, tobacco strands 112, and tobacco 120 rod may progress through the apparatus 100 at a constant rate.
- the second cutter 124 may be arranged to cut through the continuous tobacco rod 120 at regular intervals of time, thereby to produce tobacco rod segments 126 of equal length.
- the tobacco rod segments 126 may have, for example, a length in the range of 12 mm to 60 mm.
- the tobacco rod segments 126 may be 12 mm in length, or may be 42 mm in length, or may be 60 mm in length. Other lengths may be obtained, for example, by changing the interval between consecutive cuts.
- the first cutter 106 cuts the tobacco sheet 104 longitudinally to produce the plurality of tobacco strands 112.
- the gatherer 114 gathers the strands 112 together to form the tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially non-coiled, for example substantially straight.
- the second cutter 124 cuts the tobacco rod 120 into segments to produce the tobacco rod segments 126.
- the apparatus 100 thereby produces tobacco rod segments 126 each comprising a tobacco rod 130 formed of a plurality of longitudinal strands of tobacco (not shown), i.e. strands of tobacco extending along a direction of the length of the tobacco rod 130, wherein each of the plurality of longitudinal strands (not shown) are substantially non-coiled.
- the first cutter 106 may be adjustable to either cut the tobacco sheet 104 into a plurality of stands 112, or to not cut the tobacco sheet 104 at all. In use, when the apparatus 100 is first used for a given tobacco sheet 104, the first cutter 106 may be adjusted so as to not cut the tobacco sheet 104 into the plurality of strands 112. The non-cut tobacco sheet 104 may then be fed through the funnel 114 to form a tobacco rod (not shown) of non-cut tobacco sheet 104, and the resulting rod (not shown) of non-cut tobacco sheet 104 may be fed through the wrapper 122 and the second cutter 124 to form segments (not shown) of the rod (not shown) of non-cut tobacco sheet 104.
- the first cutter 106 may be adjusted to cut the tobacco sheet 104 into a plurality of strands 112 as described above, thereby to produce tobacco rod segments 126 each comprising a tobacco rod 130 formed of a plurality of strands of tobacco 112 wherein each of the plurality of strands 112 are substantially non-coiled.
- the few segments (not shown) of the rod (not shown) of non-cut tobacco sheet 104 produced before the tobacco rod segments 126 comprising a plurality of strands of tobacco 112 are produced may be discarded. This may allow for simpler and more consistent setup of the apparatus 100 on installation or replacement of tobacco sheet 104, for example a bobbin 102 of tobacco sheet 104.
- FIG. 2 there is illustrated schematically an apparatus 200, not within the scope of the appended claims, for producing tobacco rod segments 226 according to another example.

- the apparatus 200 comprises a tensioning arrangement 205 comprising a plurality (in this example four) tension rollers 205a, 205b, 205c, 205d.
- the tobacco sheet 104 is fed from the bobbin 202 over the tension rollers 205a, 205b, 205c, 205d, before being fed to the first cutter 206 in a sheet feed direction (arrow A). This may help ensure that the tobacco sheet 204 has sufficient tension, for example longitudinal tension, to be cut effectively by the first cutter 206. This may also help to smooth out the tobacco sheet 104, for example to remove any creases that may be in the tobacco sheet 104.
- the first cutter 206 comprises two cutting arrays 206a, 206b arranged to contact opposite major surfaces of the tobacco sheet 204.
- Each cutting array 206a, 206b may be the same or similar to the cutting array 106a described above with reference to Figure 1 .
- the cutting arrays 206a, 206b are arranged to press towards one another against the tobacco sheet, thereby to cut the tobacco sheet 204 longitudinally into a plurality of tobacco strands 112 (the plurality of tobacco strands 112 are distributed along a plane running into the page of Figure 2 ).
- the cutting arrays 206a, 206b may be offset from one another in a direction perpendicular to the feed direction of the tobacco sheet (i.e. offset in a direction running into the page of Figure 2 ).
- the gatherer 214 comprises a funnel 214 comprising a funnel portion 216 and a stem portion 218.
- the axis of the funnel 114 lies centrally of the plurality of tobacco strands 112 and lies in the plane along which the plurality of tobacco strands is distributed.
- the plurality of tobacco strands 112 are gathered together as they travel through funnel 214, to form a tobacco rod 220.
- the apparatus 200 comprises a wrapper 222 arranged to wrap the tobacco rod 220 in a wrapping material 228.
- the wrapper 222 may be or comprise for example, a rod maker as known in the art, for example a KDF (kinetic fluxion media) filter rod maker to control the orientation and tension wrapping material 228.
- KDF kinetic fluxion media
- the wrapper 222 comprises a drive belt 246, a wrapper material bobbin 252, a garniture 240, an adhesive section 242, and a heater section 244.
- the drive belt 246 is a continuous strip of flexible material looped around and supported by two rollers 248a, 248b.
- the drive belt 246 is held taut between the rollers 248a, 248b so as to define a generally flat upper drive belt surface 246a.
- the rollers 248a, 248b are arranged to rotate about their respective axes, so that the drive belt surface 246a may translate between the two rollers 248a, 248b.
- One or both of the rollers 248a, 248b is driven to rotate (clockwise in the sense of Figure 2 ) about its axis, so as to cause the upper drive belt surface 246a to translate (from left to right in the sense of Figure 2 ).
- the wrapping material bobbin 252 supplies a continuous sheet or web of wrapping material 228 to the upper drive belt surface 246a.
- the wrapping material 228 may be fed onto the upper drive belt surface 246a by the friction of the moving upper drive belt surface 246a against the sheet of wrapping material 228. Accordingly, the sheet of wrapping material 228 travels on top of the upper drive belt surface 246a (from left to right in the sense of Figure 2 ).
- the tobacco rod 220 is fed onto the sheet of wrapping material 228 on the upper drive belt surface 246a. Friction between the moving wrapping material 228 and the tobacco rod 220 may at least in part cause the tobacco rod 220 to be fed onto the wrapping material 228 and so to move with the wrapping material 228.
- the tobacco rod 220 may be fed onto the moving wrapping material 228 by other means, such as one or more feed rollers or the like. In either case, the tobacco rod 220 is fed onto the wrapping material 228 so that the tobacco rod 220 moves with (i.e. at the same rate as) the wrapping material 228, which in turn moves with (i.e. at the same rate as) the upper drive belt surface 246a.
- the garniture 240 folds the wrapping material 228 around the tobacco rod 220 as they move through the garniture 240.
- the garniture 240 wraps the wrapping material 228 around the circumference of the tobacco rod 220.
- the garniture wraps the wrapping material 228 around the tobacco rod 220 over slightly more than the circumference of the tobacco rod 120 so that there is a portion where the wrapping material 228 overlaps with itself (not shown).
- the adhesive section 242 applies adhesive to the wrapping material 228 so as to secure the wrapping material 228 in place around the tobacco rod 220. Specifically, the adhesive section 242 applies adhesive to the portion where the wrapping material 228 overlaps with itself, so as to secure the wrapping material 228 to itself around the tobacco rod 220.
- the heater section 244 heats the tobacco rod 220 so as to assist the drying and/or curing of the adhesive. This helps to ensure the adhesive is sufficiently dry/cured before the tobacco rod is cut into tobacco rod segments 226.
- the second cutter 224 is arranged to cut the tobacco rod 220 into segments to produce the tobacco rod segments 226.
- the second cutter 224 may be the same or similar to the second cutter 124 described above with reference to Figure 1 .
- the first cutter 206 cuts the tobacco sheet 204 longitudinally to produce the plurality of tobacco strands 212.
- the gatherer 214 gathers the strands 212 together to form the tobacco rod 220 in which each of the plurality of tobacco strands 212 is substantially non-coiled.
- the second cutter 224 cuts the tobacco rod 220 into segments to produce the tobacco rod segments 226.
- the apparatus 200 thereby produces tobacco rod segments 226 each comprising a tobacco rod 230 formed of a plurality of longitudinal strands of tobacco (not shown), i.e. strands of tobacco extending along a direction of the length of the tobacco rod 230, wherein each of the plurality of longitudinal strands (not shown) are substantially non-coiled, for example substantially straight.
- the first cutter 206 of the apparatus 200 of Figure 2 may be adjustable to either cut the tobacco sheet 104 into a plurality of longitudinal stands 112, or to not cut the tobacco sheet 104 at all. As described above, this may allow for simpler and more consistent setup of the apparatus 200 on installation or replacement of tobacco sheet 204, for example a bobbin 202 of tobacco sheet 204.
- the tobacco sheet 104, 204 is provided from a bobbin 102, 202 of tobacco sheet 104, 204.
- a bobbin 302a of tobacco sheet 304 which may for example used as the bobbin 102, 202 as described above with reference to Figures 1 and 2 , may be provided from a mother reel 370 of tobacco sheet 304.
- the mother reel 370 may be slit transversely (see dashed line 372) to produce the bobbin 302a of tobacco sheet 304.
- the mother reel 307 may be slit so as to produce a bobbin 302a having a certain width W.
- This provides that the tobacco sheet 304 of the bobbin 302a has a certain mass per unit length, and hence that the tobacco rod segments (not shown in Figure 3 ) produced have a certain mass per unit length. Accordingly, at the beginning of a manufacturing process, a desired mass per unit length of the tobacco rod segments (not shown in Figure 3 ) may be selected. A bobbin width W may then be determined based on the selected mass per unit length for the tobacco rod segment (not shown), and based on the known mass per unit area of the tobacco sheet 304 of the mother reel 370.
- the mass per unit area (also referred to as grammage) of the tobacco sheet 304 may be 100 g/m 2 .
- the mother reel 370 may then be slit to produce a bobbin 302a having the determined bobbin width W.
- the bobbin 302a may then be used, for example in the apparatus 100, 200 described above with reference to Figures 1 and 2 , to produce tobacco rod segments (not shown in Figure 3 ) having the desired mass per unit length.
- the mother reel 370 may be slit a number of times to produce bobbins 302b, 302c, 302d, 302e as desired, for example with the same or different bobbin widths W. This may allow convenient and inexpensive control over the mass per unit length of the tobacco rod segments (not shown in Figure 3 ) produced.
- Figure 4 illustrates schematically a flow diagram of a process of producing tobacco rod segments 126, 226 according to an example.
- the process may be performed using the apparatus 100, 200 described above with reference to Figures 1 and 2 , respectively.

- This may comprise providing a mother reel 307 of tobacco sheet 104, 204, 304, and slitting the mother reel to produce the bobbin 102, 202, 302a.
- This in itself may comprise selecting a mass per unit length for the tobacco rod segments 126, 226, determining, based on a mass per unit area of the tobacco sheet 104, 204, 304, and based on the selected mass per unit length for the tobacco rod segments, a bobbin width W, and slitting the mother reel 307 to produce a bobbin 102, 202, 302a having the determined bobbin width W.
- the process may comprise, prior to step S402, feeding the tobacco sheet 104, 204, in a sheet feed direction A.
- the cutting the tobacco sheet 104, 204, 304 in S402 may then comprise cutting the tobacco sheet 104, 204, 304 substantially parallel to the sheet feed direction A.
- Step S402 may comprise cutting the tobacco sheet 104, 204 with a determined cut number and/or cut spacing.
- the cut number and/or cut spacing may be determined by selecting a strand 112, 212 number and/or a strand 112, 212 width for the tobacco rod segments 126, 226, and determining, based on the selected strand number and/or strand width, the cut number and/or a cut spacing.
- Each of the plurality of strands may have a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm.
- step S404 the process comprises gathering the strands 112, 212 together to form a tobacco rod 112, 212 in which each of the plurality of tobacco strands 112, 212 is substantially non-coiled.
- Step S404 may comprise gathering the strands 112, 212 together to form the tobacco rod 120, 220 in which the plurality of tobacco strands 112, 212 are substantially parallel to one another and/or are each substantially straight.
- Step S204 may comprise gathering each of the elongate strands 112, 212 substantially transversely, towards an axis that lies centrally of the plurality of strands 112, 212, to form the rod 120.
- Step S204 may comprise feeding the strands 112, 212 through a funnel 114, 214 to gather the strands 112, 212.
- the process may comprise, before said cutting the tobacco sheet 104, 204 in step S402 is applied, feeding the tobacco sheet 104, 204 through the funnel 114, 214 to form a tobacco rod (not shown) of non-cut tobacco sheet 114, 214.
- step S406 the process comprises cutting the tobacco rod 120 (of tobacco strands 112, 212) into segments to produce said tobacco rod segments 126, 226.
- the process may comprise, prior to step S406, wrapping the tobacco rod 120, 220 in a wrapping material 128, 228.
- the wrapping material 128, 228 may be or comprise one or both of paper and aluminium foil.
- the wrapping material 128, 228 may be a laminate of paper and aluminium foil.
- the tobacco rod segments 126, 226 (being wrapped) may each have an outer diameter substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm.
- the tobacco rod segments 126, 226 may be consumables for an aerosol generating device.
- Figure 5a illustrates schematically a tobacco rod segment 526 according to an example being placed on a blade heater 580 of an aerosol-generating device (not shown). Specifically, Figure 5a illustrates the tobacco rod segment 526 before being installed over the blade heater 580, and Figure 5b illustrates the tobacco rod segment 526 after it has been installed over the blade heater 580.
- the tobacco rod segment 526 may be, for example, the same or similar to the tobacco rod segment 126, 226 described above with reference to Figures 1 and 2 , respectively.
- the tobacco rod segment 526 may be produced, for example, by the apparatus 100, 200 described above with respect to Figures 1 and 2 , respectively and/or by the process described above with respect to Figure 4 .
- the tobacco rod segment 526 comprises a tobacco rod 530 formed of a plurality of longitudinal strands 512 of tobacco, i.e. a plurality of strands 512 of tobacco extending in a direction of a length of the tobacco rod 530, wherein each of the plurality of longitudinal strands 512 are substantially non-coiled.
- the plurality of strands 512 are substantially parallel to one another, substantially straight, and each extend along substantially the entire length of the tobacco rod segment 526.
- the tobacco rod segment 526 comprises a wrapping material 528 wrapped around the tobacco rod 530.
- the blade heater 580 can take the form of an elongate cuboid that is significantly thinner than it is wide or long.
- the width of the blade heater 580 is less than the outer diameter of the tobacco rod segment 526.
- the blade heater 538 may comprise a resistive heater (not shown) powered by a battery (not shown) of a hand-held aerosol generating device (not shown) and which is controllable by a user to heat up.
- the blade heater 580 may have a pointed end (not shown) so as to facilitate insertion of the blade heater into the tobacco rod segment 526.
- the blade heater 580 may be inserted into the tobacco rod segment 526 (arrow B in Figure 5a ), or equally the tobacco rod segment 526 may be pushed over the blade heater 580, so that the blade heater 580 extends longitudinally into the tobacco rod segment 526 (as shown in Figure 5b ).
- the plurality of longitudinal strands 512 of the tobacco rod segment 526 being substantially non-coiled allow the blade heater 580 to be easily inserted into the tobacco rod segment 526. This is because the non-coiled longitudinal strands 512 present relatively little resistance to longitudinal insertion of the blade heater 580. This may provide for convenient installation or replacement of the tobacco rod segment 528 onto the blade heater 580, which tobacco rod segment 526 may be a consumable of the overall aerosol generating device (not shown). This may reduce damage to the tobacco rod segment 526 on insertion of the blade heater 580, and allow for more consistent and correct placement of the tobacco rod segment 526 relative to the blade heater 580.
- a hypothetical tobacco rod segment comprising longitudinal strands that are coiled, for example arranged in a helical structure: in this case insertion of the blade heater would be restricted by strands crossing the insertion path, and the blade heater may deform and compress portions of the tobacco, which may lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and may result in an increased risk of damaging the hypothetical tobacco rod segment.
- the plurality of longitudinal strands 512 of the tobacco rod segment 526 being parallel to one another and/or straight similarly allows the blade heater 580 to be easily inserted into the tobacco rod segment 526.
- the axis of insertion of the blade heater 580 is parallel to the axis of each of the longitudinal strands 512, and only a small surface area of tobacco is presented to the leading edge of the blade heater 580 as it is inserted.
- this may provide for convenient installation or replacement of the tobacco rod segment 526 and/or reduce damage to the tobacco rod segment 526, and/or provide for more consistent and correct placement of the tobacco rod segment 526 relative to the blade heater 580.
- a hypothetical tobacco rod segment comprising randomly oriented shreds of cut rag tobacco, or comprising crimped or corrugated sheets of tobacco: in this case insertion of a blade heater may deform and compress portions of the cut rag tobacco or edges of the crimped or corrugated sheets of tobacco, which may lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and may result in an increased risk of damaging the hypothetical tobacco rod segment.
- the blade heater 580 may be controlled to heat up (for example via resistive heating internal of the blade heater 580), and thereby to heat, but not burn, the tobacco strands 512. This may release constituents, for example volatile constituents, from the tobacco strands 512.
- the tobacco strands 512 may comprise glycerol, which may be volatilised when heated by the blade heater 580 to form an aerosol.
- the plurality of substantially non-coiled longitudinal strands 512 of the tobacco rod segment 526 establish a corresponding plurality of substantially non-coiled longitudinal pathways 513 through the tobacco rod segment 526, in between the plurality of longitudinal strands 512.
- These pathways 513 facilitate the transport of volatile materials released from the tobacco strands 512 on heating (for example volatile constituents of the tobacco itself or volatilised glycerol or both) through the tobacco rod segment 526. This may reduce the losses of such materials as they pass through the tobacco rod segment 526, for example the relatively short and uninterrupted pathways 513 may reduce occurrences of condensation of the volatile materials back onto portions of the tobacco rod segment 526.
- a hypothetical tobacco rod segment comprising randomly oriented shreds of cut rag tobacco (such as in standard cigarettes), in which the path length for volatilised materials to exit the hypothetical tobacco rod is relatively long.
- a hypothetical tobacco rod segment comprising a plurality of coiled longitudinal strands, in which the path length for volatilised materials to exit the hypothetical tobacco rod is also relatively long.
- the wrapping material 528 may, for example, be or comprise one or both of paper and aluminium foil, for example a laminate of paper and aluminium foil.
- the laminate of paper and aluminium foil may be useful to prevent the tobacco rod segment 526 from being ignited by the blade heater 580.
- Each of the plurality of strands 512 may have a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm.
- the tobacco rod segment 526 may have an outer diameter substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm. This may allow the use of a relatively large blade heater 580, hence increasing the heating surface area of the blade heater 580, hence increasing the rate at which the tobacco may be heated and/or the amount of tobacco that may be heated by the blade heater 580.
- the tobacco sheet 104, 204, 304 is described as being a sheet of reconstituted tobacco, this need not necessarily be the case, and in other examples, the tobacco sheet 104, 204, 304 may be made of other materials.

- the gatherer may be any suitable means for gathering the strands 112, 212 together to form a tobacco rod 120, 220 in which each of the plurality of tobacco strands 112, 212 is substantially non-coiled.
- the apparatus 100, 200 comprises a wrapper 122, 222 arranged to wrap the tobacco rod 120, 220 in a wrapping material 128, 228, before the tobacco rod is cut by the second cutter 124 into segments 126, 226 to produce the tobacco rod segments 126, 226, this need not necessarily be the case and in other examples the apparatus 100, 200 may not comprise a wrapper 122, 222, and the (non-wrapped) tobacco rod 120, 220 may be cut by the second cutter 124, 224 into segments 126, 226 to produce the tobacco rod segments 126, 226. In this example, the tobacco rod segments 126, 226 produced need not necessarily comprise wrapping material 128, 228.
- Figures 1 and 2 illustrate schematically examples of an apparatus for producing tobacco rod segments 126, 226 according to an example, and that in other examples, the apparatus 100, 200 may include additional (or fewer) components, for example one or more feed rollers for feeding the tobacco sheet 104 204 and/or plurality of strands 112, 212, one or more tension rollers for tensioning the tobacco sheet 104 204 and/or plurality of strands 112, 212, and/or one or more drive belts for conveying the tobacco sheet 104, 204 and/or the plurality of strands 112, 212 and/or the tobacco rod 120, 220 and/or the segments of tobacco rod 120, 220.
- additional (or fewer) components for example one or more feed rollers for feeding the tobacco sheet 104 204 and/or plurality of strands 112, 212, one or more tension rollers for tensioning the tobacco sheet 104 204 and/or plurality of strands 112, 212, and/or one or more drive belts for conveying the tobacco sheet 104,
- the tobacco strands 112, 212 are described as being straight and parallel to one another, this need not necessarily be the case, and in other examples the tobacco strands 112, 212 may not be substantially straight and/or may not be substantially parallel to one another.

Description
- The present invention relates to a process for producing heat-not-burn device consumables comprising aerosol-generating material rod segments, and to heat-not-burn device consumables.
- In a known process of manufacturing cigarettes, tobacco leaves are shredded into short fine strips, also referred to as cut rag tobacco. The shredded tobacco is then dispersed over a continuous web of cigarette paper. A machine, also known as a cigarette maker, folds the paper around the shredded tobacco to form a continuous rod. The rod is cut into segments of desired length. A filter is added to each tobacco rod segment to produce the cigarette.
- Smoking articles such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternatives to these articles by creating products that release compounds from tobacco or other materials without combusting. Examples of such products are so-called "heat not burn" products or tobacco heating devices or products or aerosol-generating devices or products, which release compounds by heating, but not burning, material, such as tobacco.

Figures 5a and 5b illustrate schematically insertion of a blade heater into a tobacco rod segment, according to an example. - Referring to
Figure 1 , in broad overview, anexample apparatus 100, not within the scope of the appended claims, for producingtobacco rod segments 126 comprises a first cutter 106, agatherer 114, and asecond cutter 124. The first cutter 106 is arranged to cut atobacco sheet 104 longitudinally to produce a plurality oftobacco strands 112. Thegatherer 114 is arranged to gather thestrands 112 together to form atobacco rod 120 in which each of the plurality oftobacco strands 112 is substantially non-coiled. Thesecond cutter 124 is arranged to cut thetobacco rod 120 into segments to producetobacco rod segments 126. - As is explained in more detail below, the
gatherer 114 being arranged to gather thestrands 112 together to form atobacco rod 120 in which each of the plurality oftobacco strands 112 is substantially non-coiled allows for the production of a number oftobacco rod segments 126 into which a blade type heater of an aerosol generating device may be readily inserted (see e.g.Figures 5a and 5b ), in use, and which facilitates transport of volatile materials therethrough thereby reducing losses of volatile materials when thetobacco rod segment 126 is heated. - Returning to
Figure 1 , the first cutter 106 is arranged to cut thetobacco sheet 104. - The
tobacco sheet 104 may be a sheet or web of reconstituted tobacco. Reconstituted tobacco sheets may be produced, for example, by a paper making process, band casting or extrusion. For example, the reconstituted tobacco sheet may be paper reconstituted tobacco. Paper reconstituted tobacco refers to tobacco material formed by a process in which tobacco feedstock is extracted with a solvent to afford an extract of solubles and a residue comprising fibrous material, and then the extract (usually after concentration, and optionally after further processing) is recombined with fibrous material from the residue (usually after refining of the fibrous material, and optionally with the addition of a portion of non-tobacco fibres) by deposition of the extract onto the fibrous material. The process of recombination resembles the process for making paper. The feedstock may comprise or consist of one or more of tobacco strips, tobacco stems, and/or whole leaf tobacco. Scraps, fines and winnowings may alternatively or additionally be employed in the feedstock. It will be appreciated thatreconstituted tobacco sheet 104 formed by any process may be used. t - The reconstituted
tobacco sheet 104 is malleable. - The
tobacco sheet 104 may be provided from abobbin 102 oftobacco sheet 104. Thebobbin 102 comprises aspindle 102a around whichcontinuous tobacco sheet 104 is wound. Thebobbin 102 is arranged to rotate to feed thetobacco sheet 104 from thebobbin 102 to the first cutter 106 along a sheet feed direction (arrow A). In some examples, theapparatus 100 may be arranged to drive thebobbin 102 to rotate. In other examples, thebobbin 102 may be free to rotate, and thetobacco sheet 104 being pulled from thebobbin 102 by a downstream component of the apparatus, for example a roller or drive belt (not shown inFigure 1 ) may cause the bobbin to rotate. - The
tobacco sheet 104 may comprise glycerol. For example, the reconstitutedtobacco sheet 104 may be impregnated or otherwise formed with glycerol. When heated, the glycerol may be volatilised to form an aerosol, which may enhance user experience of an aerosol-generating device, or any suitable "heat not burn" device, with which thetobacco rod segment 126 may be used. - The
tobacco sheet 104 is of known dimensions. For example, the width and thickness of thetobacco sheet 104 fed from thebobbin 102 may be constant and known. For example, thetobacco sheet 104 may be of a given and constant mass per unit length. This may ensure that thetobacco rod segments 126 produced are of consistent weight per unit length. Using atobacco sheet 104 of known (and constant) dimensions therefore allows weight control of the resultingtobacco rod segments 126 without the need for weighing systems for weighing thetobacco rod 120 ortobacco rod segments 126. - The first cutter 106 is arranged to cut the
tobacco sheet 104 longitudinally to produce a plurality oftobacco strands 112. Thetobacco strands 112 produced are elongate. The first cutter 106 comprises a cutter array 106a. The cutter array 106a comprises a plurality ofcircular discs 108 arranged along anaxle 110. Thediscs 108 each have sharpened edges. Theaxle 110 is arranged substantially perpendicularly to the sheet feed direction (arrow A), and eachdisc 108 is arranged such that the cutting edge of thedisc 108 runs substantially parallel to the sheet feed direction (arrow A). Eachdisc 108 is arranged to cut thetobacco sheet 104 longitudinally i.e. to cut thetobacco sheet 104 along its length, as thetobacco sheet 104 is fed through the first cutter 106. For example, the cutter array 106a may cut thetobacco sheet 104 against a support surface (not shown) arranged on an opposite side of thetobacco sheet 104 to the cutter array 106a. The plurality ofdiscs 108 act to cut thetobacco sheet 104 into a plurality of substantially parallelelongate tobacco strands 112. - The number of
tobacco strands 112 produced depends on the number of cuttingdiscs 108 the cutter array 106a comprises. For example, a cutter array 106a comprising eight cuttingdiscs 108 will produce a total of nine tobacco strands. In general, a cutter array 106a comprisingn cutting discs 108 will produce n+1tobacco strands 112. - The strand width of the
tobacco strands 112 depends on the spacing between consecutive ones of the cuttingdiscs 108. Thediscs 108 are equally spaced along the length of theaxle 110, and along the width of thetobacco sheet 104, so that each of theelongate tobacco strands 112 is of substantially equal width. This arrangement may help to ensure consistency of thetobacco rod segments 126 produced. The cutter array 106a may be arranged such that each of the plurality ofelongate tobacco strands 112 has a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm. This would correspond, for example, to the cuttingdiscs 108 being spaced apart by substantially 0.25 mm to 3 mm, or substantially 0.5 mm to 1.5 mm, respectively. - The first cutter 106 may be adjustable so as to adjust the number and/or width of the
strands 112 into which thetobacco sheet 104 is cut. For example, the cuttingdiscs 108 may be adjustable on theaxle 110 to adjust the number ofdiscs 108 on the axle and/or to adjust the spacing between eachdisc 108 along theaxle 110. As another example, the cutter array 106a may be replaceable by another cutter array 106a having a different number ofdiscs 108 and/or different spacing between thediscs 108. This allows flexibility in the number and/or width of thestrands 112 in thetobacco rod segments 126 produced, and hence flexibility in the characteristics of thosetobacco rod segments 126. - The
gatherer 114 is arranged to gather the plurality oftobacco strands 112 together to form atobacco rod 120. Thegatherer 114 is afunnel 114. Thefunnel 114 comprises afunnel portion 116 and astem portion 118. Thefunnel portion 116 and thestem portion 118 are circular in cross-section, and are coaxial. Thefunnel 114 is symmetric about its axis. Thefunnel portion 116 narrows from a relativelywide mouth 116a to the relativelynarrow stem portion 118. Thetobacco strands 112 travel through thefunnel 114 from thefunnel portion 116 to thestem portion 118. As thetobacco strands 112 travel through thefunnel 114, the narrowing diameter of thefunnel portion 116 gathers thestrands 112 together to form thetobacco rod 120. - The
funnel 114 is aligned with and positioned centrally of the plurality oftobacco strands 112. Thefunnel 114 therefore gathers each of thestrands 112 substantially transversely to form therod 120. Specifically, thefunnel 114 gathers each of thestrands 112 towards an axis that lies centrally of the plurality ofstrands 112. Thefunnel 114 being aligned with thetobacco strands 112 in this way may allow thestrands 112 to be gathered evenly and centrally of thefunnel 114. - The
funnel 114 is aligned with and positioned centrally of thetobacco sheet 104. Specifically, the axis towards which thestrands 112 are gathered by thefunnel 114 lies in a first plane, the first plane including the feed direction (arrow A) and being perpendicular to a second plane defined by the plurality ofstrands 112 before they are gathered. This alignment may help ensure an even tension across the plurality ofstrands 112 as they are gathered by thefunnel 114. - The
funnel 114 applies substantially transverse forces to thestrands 112 as they pass through thefunnel 114, which transverse forces are directed substantially centrally of the plurality ofstrands 112. Thetobacco strands 112 are not coiled as they are gathered, i.e. remain substantially non-coiled as they are gathered (i.e. during the gathering), i.e. as they pass through thefunnel 114. For example, thetobacco strands 112 are not twisted, spiralled, rolled or intertwined relative to one another as they are gathered, for example they do not form a twisted or spiralled or helical structure or shape as they are gathered. Thefunnel 114 therefore gathers thestrands 112 together to form thetobacco rod 120 in which each of the plurality oftobacco strands 112 are substantially non-coiled. Thetobacco strands 112 remain substantially parallel to one another as they are gathered, i.e. as they pass through thefunnel 114. Thefunnel 114 therefore gathers thestrands 112 together to form thetobacco rod 120 in which the plurality oftobacco strands 112 are substantially parallel to one another. Thetobacco strands 112 are not substantially bent, corrugated, crimped or deformed or the like as they are gathered, and remain substantially straight as they are gathered, i.e. as they pass through thefunnel 114. Thefunnel 114 therefore gathers thestrands 112 together to form thetobacco rod 120 in which each of the plurality oftobacco strands 112 is substantially straight. - The
apparatus 100 comprises awrapper 122 arranged to wrap thetobacco rod 120 in awrapping material 128. Thewrapper 122 may be, for example, the same as or similar to the wrapper 222 described below with reference toFigure 2 . In brief, thewrapper 122 wraps a continuous sheet of wrappingmaterial 128 around a circumference of thecontinuous tobacco rod 120, and applies adhesive to thewrapping material 128 to seal thewrapping material 128 in place around therod 120. The wrapping material may be or comprise, for example, one or both of paper and aluminium foil. For example, the wrapping material may be a laminate of aluminium foil and paper. This laminate may help prevent ignition of thetobacco rod segment 126, which may be useful for example where thetobacco rod segment 126 is for use as a consumable in a "heat not burn" device, or a tobacco heating product device, or an aerosol-generating device. - The outer diameter of the
tobacco rod 120 once wrapped may depend, for example, on the mass per unit length of thetobacco sheet 104 used, the thickness and width of thetobacco sheet 104 used, the level of compression in the garniture during rod forming, and/or for example properties of thewrapper 122 and/or wrappingmaterial 128 used. The outer diameter of the wrappedtobacco rod 120 may be constant during a given operational cycle of theapparatus 100. The outer diameter may be substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm, for example. - The
second cutter 124 is arranged to cut the tobacco rod 120 (for example after it has been wrapped in wrappingmaterial 128 by the wrapper 122) intosegments 126 to produce thetobacco rod segments 126. Thesecond cutter 124 cuts through thetobacco rod 120 transversely, so as to produce lengths of tobacco rod 120 (i.e. thetobacco rod segments 126. Thesecond cutter 124 may comprise, for example, a blade (not shown) whose cutting surface (not shown) is arranged perpendicularly to the length of thetobacco rod 120, and is controllable to slice through thetobacco rod 120. Thetobacco sheet 104,tobacco strands 112, andtobacco 120 rod may progress through theapparatus 100 at a constant rate. Thesecond cutter 124 may be arranged to cut through thecontinuous tobacco rod 120 at regular intervals of time, thereby to producetobacco rod segments 126 of equal length. Thetobacco rod segments 126 may have, for example, a length in the range of 12 mm to 60 mm. For example, thetobacco rod segments 126 may be 12 mm in length, or may be 42 mm in length, or may be 60 mm in length. Other lengths may be obtained, for example, by changing the interval between consecutive cuts. - In use, the first cutter 106 cuts the
tobacco sheet 104 longitudinally to produce the plurality oftobacco strands 112. Thegatherer 114 gathers thestrands 112 together to form thetobacco rod 120 in which each of the plurality oftobacco strands 112 is substantially non-coiled, for example substantially straight. Thesecond cutter 124 cuts thetobacco rod 120 into segments to produce thetobacco rod segments 126. - The
apparatus 100 thereby producestobacco rod segments 126 each comprising atobacco rod 130 formed of a plurality of longitudinal strands of tobacco (not shown), i.e. strands of tobacco extending along a direction of the length of thetobacco rod 130, wherein each of the plurality of longitudinal strands (not shown) are substantially non-coiled. - The first cutter 106 may be adjustable to either cut the
tobacco sheet 104 into a plurality ofstands 112, or to not cut thetobacco sheet 104 at all. In use, when theapparatus 100 is first used for a giventobacco sheet 104, the first cutter 106 may be adjusted so as to not cut thetobacco sheet 104 into the plurality ofstrands 112. Thenon-cut tobacco sheet 104 may then be fed through thefunnel 114 to form a tobacco rod (not shown) ofnon-cut tobacco sheet 104, and the resulting rod (not shown) ofnon-cut tobacco sheet 104 may be fed through thewrapper 122 and thesecond cutter 124 to form segments (not shown) of the rod (not shown) ofnon-cut tobacco sheet 104. Once the formation of the rod (not shown) ofnon-cut tobacco sheet 104 is stable, for example, once a few segments (not shown) of the rod (not shown) ofnon-cut tobacco sheet 104 have been produced, the first cutter 106 may be adjusted to cut thetobacco sheet 104 into a plurality ofstrands 112 as described above, thereby to producetobacco rod segments 126 each comprising atobacco rod 130 formed of a plurality of strands oftobacco 112 wherein each of the plurality ofstrands 112 are substantially non-coiled. The few segments (not shown) of the rod (not shown) ofnon-cut tobacco sheet 104 produced before thetobacco rod segments 126 comprising a plurality of strands oftobacco 112 are produced, may be discarded. This may allow for simpler and more consistent setup of theapparatus 100 on installation or replacement oftobacco sheet 104, for example abobbin 102 oftobacco sheet 104. - Referring now to
Figure 2 , there is illustrated schematically anapparatus 200, not within the scope of the appended claims, for producingtobacco rod segments 226 according to another example. Components of theapparatus 200 illustrated inFigure 2 that are the same or similar to the components already described with reference toFigure 1 will not be described again in detail, but are given the same reference signs to as inFigure 1 except increased by 100. - The
apparatus 200 comprises afirst cutter 206, agatherer 214, and asecond cutter 224. Thefirst cutter 206 is arranged to cut atobacco sheet 204 longitudinally to produce a plurality oftobacco strands 212. Thegatherer 214 is arranged to gather thestrands 212 together to form atobacco rod 220 in which each of the plurality oftobacco strands 212 is substantially non-coiled, for example substantially straight. Thesecond cutter 224 is arranged to cut thetobacco rod 220 intosegments 226 to produce thetobacco rod segments 226. - The
apparatus 200 comprises abobbin 202 oftobacco sheet 204. Thetobacco sheet 204 is fed towards thefirst cutter 226 from thebobbin 202 oftobacco sheet 204. - The
apparatus 200 comprises atensioning arrangement 205 comprising a plurality (in this example four)tension rollers tobacco sheet 104 is fed from thebobbin 202 over thetension rollers first cutter 206 in a sheet feed direction (arrow A). This may help ensure that thetobacco sheet 204 has sufficient tension, for example longitudinal tension, to be cut effectively by thefirst cutter 206. This may also help to smooth out thetobacco sheet 104, for example to remove any creases that may be in thetobacco sheet 104. - The
first cutter 206 comprises two cuttingarrays tobacco sheet 204. Each cuttingarray Figure 1 . The cuttingarrays tobacco sheet 204 longitudinally into a plurality of tobacco strands 112 (the plurality oftobacco strands 112 are distributed along a plane running into the page ofFigure 2 ). For example, the cuttingarrays Figure 2 ). - The
gatherer 214 comprises afunnel 214 comprising afunnel portion 216 and astem portion 218. The axis of thefunnel 114 lies centrally of the plurality oftobacco strands 112 and lies in the plane along which the plurality of tobacco strands is distributed. The plurality oftobacco strands 112 are gathered together as they travel throughfunnel 214, to form atobacco rod 220. - The
apparatus 200 comprises a wrapper 222 arranged to wrap thetobacco rod 220 in awrapping material 228. The wrapper 222 may be or comprise for example, a rod maker as known in the art, for example a KDF (kinetic fluxion media) filter rod maker to control the orientation andtension wrapping material 228. - The wrapper 222 comprises a
drive belt 246, awrapper material bobbin 252, agarniture 240, anadhesive section 242, and aheater section 244. - The
drive belt 246 is a continuous strip of flexible material looped around and supported by tworollers drive belt 246 is held taut between therollers drive belt surface 246a. Therollers drive belt surface 246a may translate between the tworollers rollers Figure 2 ) about its axis, so as to cause the upperdrive belt surface 246a to translate (from left to right in the sense ofFigure 2 ). - The wrapping
material bobbin 252 supplies a continuous sheet or web of wrappingmaterial 228 to the upperdrive belt surface 246a. The wrappingmaterial 228 may be fed onto the upperdrive belt surface 246a by the friction of the moving upperdrive belt surface 246a against the sheet of wrappingmaterial 228. Accordingly, the sheet of wrappingmaterial 228 travels on top of the upperdrive belt surface 246a (from left to right in the sense ofFigure 2 ). Thetobacco rod 220 is fed onto the sheet of wrappingmaterial 228 on the upperdrive belt surface 246a. Friction between the movingwrapping material 228 and thetobacco rod 220 may at least in part cause thetobacco rod 220 to be fed onto the wrappingmaterial 228 and so to move with the wrappingmaterial 228. Alternatively or additionally, thetobacco rod 220 may be fed onto the movingwrapping material 228 by other means, such as one or more feed rollers or the like. In either case, thetobacco rod 220 is fed onto the wrappingmaterial 228 so that thetobacco rod 220 moves with (i.e. at the same rate as) thewrapping material 228, which in turn moves with (i.e. at the same rate as) the upperdrive belt surface 246a. - The
garniture 240, as is known per se, folds the wrappingmaterial 228 around thetobacco rod 220 as they move through thegarniture 240. Thegarniture 240 wraps the wrappingmaterial 228 around the circumference of thetobacco rod 220. The garniture wraps the wrappingmaterial 228 around thetobacco rod 220 over slightly more than the circumference of thetobacco rod 120 so that there is a portion where the wrappingmaterial 228 overlaps with itself (not shown). - The
adhesive section 242 applies adhesive to thewrapping material 228 so as to secure thewrapping material 228 in place around thetobacco rod 220. Specifically, theadhesive section 242 applies adhesive to the portion where the wrappingmaterial 228 overlaps with itself, so as to secure thewrapping material 228 to itself around thetobacco rod 220. - The
heater section 244 heats thetobacco rod 220 so as to assist the drying and/or curing of the adhesive. This helps to ensure the adhesive is sufficiently dry/cured before the tobacco rod is cut intotobacco rod segments 226. - The
second cutter 224 is arranged to cut thetobacco rod 220 into segments to produce thetobacco rod segments 226. Thesecond cutter 224 may be the same or similar to thesecond cutter 124 described above with reference toFigure 1 . - In use, the
first cutter 206 cuts thetobacco sheet 204 longitudinally to produce the plurality oftobacco strands 212. Thegatherer 214 gathers thestrands 212 together to form thetobacco rod 220 in which each of the plurality oftobacco strands 212 is substantially non-coiled. Thesecond cutter 224 cuts thetobacco rod 220 into segments to produce thetobacco rod segments 226. - The
apparatus 200 thereby producestobacco rod segments 226 each comprising a tobacco rod 230 formed of a plurality of longitudinal strands of tobacco (not shown), i.e. strands of tobacco extending along a direction of the length of the tobacco rod 230, wherein each of the plurality of longitudinal strands (not shown) are substantially non-coiled, for example substantially straight. - Similarly to as described with reference to the
apparatus 100 ofFigure 1 , thefirst cutter 206 of theapparatus 200 ofFigure 2 may be adjustable to either cut thetobacco sheet 104 into a plurality oflongitudinal stands 112, or to not cut thetobacco sheet 104 at all. As described above, this may allow for simpler and more consistent setup of theapparatus 200 on installation or replacement oftobacco sheet 204, for example abobbin 202 oftobacco sheet 204. - As mentioned above, in some examples the
tobacco sheet bobbin tobacco sheet - Referring to
Figure 3 , abobbin 302a oftobacco sheet 304, which may for example used as thebobbin Figures 1 and2 , may be provided from amother reel 370 oftobacco sheet 304. Themother reel 370 may be slit transversely (see dashed line 372) to produce thebobbin 302a oftobacco sheet 304. - The mother reel 307 may be slit so as to produce a
bobbin 302a having a certain width W. This provides that thetobacco sheet 304 of thebobbin 302a has a certain mass per unit length, and hence that the tobacco rod segments (not shown inFigure 3 ) produced have a certain mass per unit length. Accordingly, at the beginning of a manufacturing process, a desired mass per unit length of the tobacco rod segments (not shown inFigure 3 ) may be selected. A bobbin width W may then be determined based on the selected mass per unit length for the tobacco rod segment (not shown), and based on the known mass per unit area of thetobacco sheet 304 of themother reel 370. For example, the mass per unit area (also referred to as grammage) of thetobacco sheet 304 may be 100 g/m2. Themother reel 370 may then be slit to produce abobbin 302a having the determined bobbin width W. Thebobbin 302a may then be used, for example in theapparatus Figures 1 and2 , to produce tobacco rod segments (not shown inFigure 3 ) having the desired mass per unit length. Themother reel 370 may be slit a number of times to producebobbins Figure 3 ) produced. -
Figure 4 illustrates schematically a flow diagram of a process of producingtobacco rod segments apparatus Figures 1 and2 , respectively. Reference signs used inFigures 1 and2 are therefore also used in the below as appropriate. - In step S402, the process comprises cutting a
tobacco sheet tobacco strands - The

tobacco strands 112, 212) into segments to produce saidtobacco rod segments - The process may comprise, prior to step S406, wrapping the
tobacco rod wrapping material material material tobacco rod segments 126, 226 (being wrapped) may each have an outer diameter substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm. Thetobacco rod segments -
Figure 5a illustrates schematically atobacco rod segment 526 according to an example being placed on ablade heater 580 of an aerosol-generating device (not shown). Specifically,Figure 5a illustrates thetobacco rod segment 526 before being installed over theblade heater 580, andFigure 5b illustrates thetobacco rod segment 526 after it has been installed over theblade heater 580. - The
tobacco rod segment 526 may be, for example, the same or similar to thetobacco rod segment Figures 1 and2 , respectively. Thetobacco rod segment 526 may be produced, for example, by theapparatus Figures 1 and2 , respectively and/or by the process described above with respect toFigure 4 . - Referring to
Figures 5a and 5b , thetobacco rod segment 526 comprises atobacco rod 530 formed of a plurality oflongitudinal strands 512 of tobacco, i.e. a plurality ofstrands 512 of tobacco extending in a direction of a length of thetobacco rod 530, wherein each of the plurality oflongitudinal strands 512 are substantially non-coiled. The plurality ofstrands 512 are substantially parallel to one another, substantially straight, and each extend along substantially the entire length of thetobacco rod segment 526. Thetobacco rod segment 526 comprises a wrappingmaterial 528 wrapped around thetobacco rod 530. - The
blade heater 580 can take the form of an elongate cuboid that is significantly thinner than it is wide or long. The width of theblade heater 580 is less than the outer diameter of thetobacco rod segment 526. The blade heater 538 may comprise a resistive heater (not shown) powered by a battery (not shown) of a hand-held aerosol generating device (not shown) and which is controllable by a user to heat up. In some examples, theblade heater 580 may have a pointed end (not shown) so as to facilitate insertion of the blade heater into thetobacco rod segment 526. - The
blade heater 580 may be inserted into the tobacco rod segment 526 (arrow B inFigure 5a ), or equally thetobacco rod segment 526 may be pushed over theblade heater 580, so that theblade heater 580 extends longitudinally into the tobacco rod segment 526 (as shown inFigure 5b ). - The plurality of
longitudinal strands 512 of thetobacco rod segment 526 being substantially non-coiled allow theblade heater 580 to be easily inserted into thetobacco rod segment 526. This is because the non-coiledlongitudinal strands 512 present relatively little resistance to longitudinal insertion of theblade heater 580. This may provide for convenient installation or replacement of thetobacco rod segment 528 onto theblade heater 580, whichtobacco rod segment 526 may be a consumable of the overall aerosol generating device (not shown). This may reduce damage to thetobacco rod segment 526 on insertion of theblade heater 580, and allow for more consistent and correct placement of thetobacco rod segment 526 relative to theblade heater 580. This may be contrasted, for example, with a hypothetical tobacco rod segment comprising longitudinal strands that are coiled, for example arranged in a helical structure: in this case insertion of the blade heater would be restricted by strands crossing the insertion path, and the blade heater may deform and compress portions of the tobacco, which may lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and may result in an increased risk of damaging the hypothetical tobacco rod segment. - The plurality of
longitudinal strands 512 of thetobacco rod segment 526 being parallel to one another and/or straight similarly allows theblade heater 580 to be easily inserted into thetobacco rod segment 526. In this case, the axis of insertion of theblade heater 580 is parallel to the axis of each of thelongitudinal strands 512, and only a small surface area of tobacco is presented to the leading edge of theblade heater 580 as it is inserted. Similarly to as mentioned above, this may provide for convenient installation or replacement of thetobacco rod segment 526 and/or reduce damage to thetobacco rod segment 526, and/or provide for more consistent and correct placement of thetobacco rod segment 526 relative to theblade heater 580. This may be contrasted, for example, with a hypothetical tobacco rod segment comprising randomly oriented shreds of cut rag tobacco, or comprising crimped or corrugated sheets of tobacco: in this case insertion of a blade heater may deform and compress portions of the cut rag tobacco or edges of the crimped or corrugated sheets of tobacco, which may lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and may result in an increased risk of damaging the hypothetical tobacco rod segment. - Once the
tobacco rod segment 526 is inserted over theblade heater 580 of the overall aerosol generating device (not shown), theblade heater 580 may be controlled to heat up (for example via resistive heating internal of the blade heater 580), and thereby to heat, but not burn, thetobacco strands 512. This may release constituents, for example volatile constituents, from thetobacco strands 512. As mentioned above, thetobacco strands 512 may comprise glycerol, which may be volatilised when heated by theblade heater 580 to form an aerosol. - The plurality of substantially non-coiled
longitudinal strands 512 of thetobacco rod segment 526 establish a corresponding plurality of substantially non-coiledlongitudinal pathways 513 through thetobacco rod segment 526, in between the plurality oflongitudinal strands 512. Thesepathways 513 facilitate the transport of volatile materials released from thetobacco strands 512 on heating (for example volatile constituents of the tobacco itself or volatilised glycerol or both) through thetobacco rod segment 526. This may reduce the losses of such materials as they pass through thetobacco rod segment 526, for example the relatively short anduninterrupted pathways 513 may reduce occurrences of condensation of the volatile materials back onto portions of thetobacco rod segment 526. This may be contrasted for example, with a hypothetical tobacco rod segment comprising randomly oriented shreds of cut rag tobacco (such as in standard cigarettes), in which the path length for volatilised materials to exit the hypothetical tobacco rod is relatively long. This may also be contrasted with a hypothetical tobacco rod segment comprising a plurality of coiled longitudinal strands, in which the path length for volatilised materials to exit the hypothetical tobacco rod is also relatively long. - As mentioned above, the wrapping
material 528 may, for example, be or comprise one or both of paper and aluminium foil, for example a laminate of paper and aluminium foil. The laminate of paper and aluminium foil may be useful to prevent thetobacco rod segment 526 from being ignited by theblade heater 580. - Each of the plurality of
strands 512 may have a width substantially in the range 0.25 mm to 3 mm, or substantially in the range 0.5 mm to 1.5 mm. Thetobacco rod segment 526 may have an outer diameter substantially in the range 5.4 mm to 7.8 mm, or substantially in the range 6.7 mm to 7.8 mm. This may allow the use of a relativelylarge blade heater 580, hence increasing the heating surface area of theblade heater 580, hence increasing the rate at which the tobacco may be heated and/or the amount of tobacco that may be heated by theblade heater 580. - The above examples are to be understood as illustrative examples of the invention.

For example, the sheet of aerosol-generatingmaterial flavour substrate - It may be noted that, in general, an aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas, where a colloid is a substance in which microscopically dispersed insoluble particles are suspended throughout another substance. On the other hand, a vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that for example the vapour can be condensed to a liquid by increasing its pressure without reducing the temperature. It is to be understood that as used herein the term aerosol includes aerosol and/or vapour.
