DESCRIPTION

Rod segment of aerosol generating material

technical field

The present invention relates to a process for producing non-combustion heating device consumables comprising rod segments of aerosol generating material, and to non-combustion heating device consumables.

Background

In a known cigarette manufacturing process, tobacco leaves are shredded into short, thin strips, also called cut string tobacco. The shredded tobacco is then dispersed onto a continuous sheet of cigarette paper. A machine, also known as a cigarette maker, folds the paper around the shredded tobacco to form a continuous rod. The bar is cut into segments of the 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 items by creating products that release compounds from tobacco or other materials without combustion. Examples of such products are so-called "heat without combustion" products or tobacco heating devices or products or aerosol generating devices or products, which release compounds when heating, but not when burning material, such as tobacco.

EP 0246 107 A2 discloses rods made by chopping strips of sheet-shaped reconstituted tobacco material into a plurality of strings. The yarns are brought together in the form of a bar and circumscribed with a paper wrapper to provide a continuous bar. The continuous bar is cut at regular intervals to provide a plurality of bars of the desired length. The resulting bars have a plurality of substantially longitudinally extending strands provided with the material in the form of shredded sheet. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.

Document ES 1234786 A discloses a tobacco rod for a smoking product that incorporates a tobacco filler in the form of a bundle of longitudinally extending reconstituted tobacco filaments surrounded by a tubular casing, each filament extending from end to end of the tobacco rod substantially parallel to the other filaments. The rod can be made by guiding a bale of reconstituted tobacco strands into a lining from which the loose bale emerges as a tight cylindrical bale. This pack is married to a continuous sheet of cigarette paper from which a continuous stick is produced in a stick making device. The bar is cut into sections with a guillotine.

US 5025814 A discloses filter rods for the manufacture of cigarettes including a plurality of strands of a reconstituted tobacco material. The tobacco material includes a sizing agent having a hydrophobic character. A bar having a circumference of about 24mm may have about 320 strands of sheet-like material cut at about 32 cuts per inch. The threads extend along the length of the bar. The filter elements supplied by the rods provide a useful mouthpiece for cigarettes and also impart a unique tobacco flavor.

Detailed description

Referring to Figure 1, in general description, an exemplary apparatus 100, not falling within the scope of the appended claims, for producing tobacco rod segments 126 comprises a first cutter 106, a picker 114 and a second cutter. 124. The first cutter 106 is arranged to cut a tobacco sheet 104 longitudinally to produce a plurality of tobacco strings 112. Picker 114 is arranged to bundle strands 112 to form a tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially unwound. The second cutter 124 is arranged to cut the tobacco rod 120 into segments to produce tobacco rod segments 126 .

As explained in more detail below, the collector 114 is arranged to join the strands 112 to form a tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially unwound, allowing for the production of several tobacco rod segments 126 into which a blade-type heater of an aerosol generating device (see, for example, Figures 5a and 5b) can be easily inserted, in use, and which facilitates transport of volatile materials through of them, thus reducing the losses of volatile materials when the tobacco rod segment 126 is heated.

Returning to Figure 1, the first cutter 106 is arranged to cut the tobacco sheet 104.

The tobacco wafer 104 may be a reconstituted tobacco wafer or band. The reconstituted tobacco leaves can be produced, for example, by a papermaking, strip casting or extrusion process. For example, the reconstituted tobacco leaf can be paper reconstituted tobacco. Paper-reconstituted tobacco refers to tobacco material formed by a process in which tobacco raw material is extracted with a solvent to produce an extract of solubles and a residue comprising fibrous material, and then the extract (generally after concentration and optionally after further processing) is recombined with material extract of the residue (usually after refining the fibrous material and, optionally, with the addition of a portion of non-tobacco fibers) by depositing the extract onto the fibrous material. The recombination process resembles the paper-making process. The raw material may comprise or consist of one or more tobacco strips, tobacco stems, and/or whole leaf tobacco. Waste, fines and winnowing can be used alternatively or additionally in the raw material. It will be appreciated that the reconstituted tobacco sheet 104 formed by any process can be used. you

The reconstituted tobacco wafer 104 is malleable.

Tobacco sheet 104 may be provided from a reel 102 of tobacco sheet 104. The reel 102 comprises a shaft 102a around which a continuous sheet of tobacco 104 is wound. The reel 102 is arranged to rotate to feed the tobacco sheet 104 from the reel 102 to the first cutter 106 along a sheet-feeding direction (arrow A). In some examples, the apparatus 100 may be arranged to rotate the reel 102. In other examples, the reel 102 is free to rotate, and the tobacco sheet 104, when removed from the reel 102 by a component downstream of the apparatus, by For example, a roller or a drive belt (not shown in figure 1), can cause the coil to rotate.

Tobacco wafer 104 may comprise glycerol. For example, the reconstituted tobacco wafer 104 may be impregnated or otherwise formed with glycerol. When heated, glycerol can volatilize to form an aerosol, which can enhance the user experience of an aerosol generating device, or any suitable "heat without combustion" device, with which the rod segment 126 may be used. tobacco.

The tobacco sheet 104 is of known dimensions. For example, the width and thickness of the tobacco sheet 104 fed from the reel 102 may be constant and known. For example, the tobacco sheet 104 may have a given and constant mass per unit length. This can ensure that the tobacco rod segments 126 produced have a constant weight per unit length. The use of a tobacco sheet 104 of known (and constant) dimensions therefore allows the weight of the resulting tobacco rod segments 126 to be controlled without the need for weighing systems to weigh the tobacco rod 120 or the segments 126 of tobacco bar.

The first cutter 106 is arranged to cut the tobacco sheet 104 longitudinally to produce a plurality of tobacco strings 112. The produced tobacco strands 112 are elongated. The first cutter 106 comprises a set of cutters 106a. The cutter assembly 106a comprises a plurality of circular discs 108 arranged along an axis 110. Each of the discs 108 has sharp edges. The axis 110 is arranged substantially perpendicular to the sheet feed direction (arrow A), and each disc 108 is arranged so 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 lengthwise, that is, to cut the tobacco sheet 104 lengthwise, as the tobacco sheet 104 is fed through the first cutter 106. For example, the set cutter 106a can cut tobacco sheet 104 against a support surface (not shown) disposed on an opposite side of tobacco sheet 104 to cutter assembly 106a. The plurality of discs 108 act to cut the tobacco wafer 104 into a plurality of substantially parallel elongated tobacco strings 112 .

The number of tobacco strands 112 produced depends on the number of cutting discs 108 that the cutter assembly 106a comprises. For example, a cutter assembly 106a comprising eight cutting discs 108 will produce a total of nine tobacco strands. In general, a set of cutters 106a comprising n cutting discs 108 will produce n+1 tobacco strings 112.

The width of the strings of the tobacco strings 112 depends on the spacing between the consecutive lines of the cutting discs 108. The discs 108 are equally spaced along the axis 110 and along the width of the tobacco wafer 104, such that each of the elongated tobacco strings 112 is substantially the same width. This arrangement can help ensure the consistency of the tobacco rod segments 126 produced. Cutter assembly 106a may be arranged so that each of the plurality of elongated tobacco strings 112 has a width substantially in the range of 0.25mm to 3mm, or substantially in the range of 0.5mm to 1.5mm. This would correspond, for example, to the cutting discs 108 being substantially 0.25mm and 3mm apart, or substantially 0.5mm and 1.5mm apart, respectively.

The first cutter 106 may be adjustable to adjust the number and/or width of the strings 112 into which the tobacco sheet 104 is cut. For example, cutting discs 108 may be adjustable on axis 110 to adjust the number of discs 108 on axis y/or to adjust the spacing between each disc 108 along axis 110. As another example, assembly 106a of cutters can be replaced by another set of cutters 106a that has a different number of discs 108 and/or a different spacing between discs 108. This allows flexibility in the number and/or width of the wires 112 on the bar segments 126. tobacco produced and therefore flexibility in the characteristics of those tobacco rod segments 126.

Picker 114 is arranged to bundle the plurality of tobacco strands 112 to form a tobacco rod 120. Manifold 114 is a funnel 114. Funnel 114 comprises a funnel portion 116 and a tube portion 118. stem. Funnel portion 116 and stem portion 118 have a circular cross section and are coaxial. The funnel 114 is symmetrical with respect to its axis. Funnel portion 116 tapers from a relatively wide mouth 116a to relatively narrow stem portion 118. Tobacco strands 112 travel through funnel 114 from funnel portion 116 to stem portion 118. As the tobacco strands 112 travel through the funnel 114, the narrowing diameter of the funnel portion 116 bundles the strands 112 together to form the tobacco rod 120.

The funnel 114 is aligned and positioned in the center of the plurality of tobacco strands 112. Therefore, the funnel 114 gathers each of the wires 112 substantially transversely to form the bar 120. Specifically, the funnel 114 gathers each of the wires 112 toward an axis that is in the center of the plurality of wires. 112. The funnel 114 being aligned with the tobacco strings 112 in this way can allow the strings 112 to be collected evenly and in the center of the funnel 114.

The funnel 114 is aligned and positioned in the center of the tobacco sheet 104. Specifically, the axis towards which the threads 112 are picked up by the funnel 114 lies in a first plane, the first plane including the feeding direction (arrow A) and being perpendicular to a second plane defined by the plurality of threads 112 above. for them to be collected. This alignment can help ensure uniform tension across the plurality of yarns 112 as they come together in 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 to the center of the plurality of strands 112. The tobacco strands 112 do not roll when collected, i.e. , remain substantially uncoiled when collected (ie, during collection), ie, as they pass through funnel 114. For example, tobacco strands 112 do not twist, spiral, coil, or intertwine with one another when put together, for example, they do not form a twisted, spiral, or helical structure or shape when put together. Therefore, the funnel 114 gathers the strands 112 to form the tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially unwound. The tobacco strands 112 remain substantially parallel to one another when they are brought together, that is, when they pass through the funnel 114. The funnel 114 therefore brings the strands 112 together to form the tobacco rod 120 in which the plurality of strands 112 of tobacco are substantially parallel to each other. The tobacco strands 112 do not substantially bend, curl, curl, or deform or the like when they are brought together, and remain substantially straight while they are brought together, that is, when they pass through the funnel 114. Therefore, the funnel 114 gathers the strands together. 112 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 wrapper material 128. Wrap 122 can be, for example, the same or similar to wrap 222 described below with reference to Figure 2. Briefly, wrap 122 wraps a continuous sheet of wrap material 128 around a circumference of the bar. 120 continues and applies adhesive to the wrapping material 128 to seal the wrapping material 128 in place around the rod 120. The wrapping material can be or comprise, for example, one or both of paper and aluminum foil. For example, the wrapping material can be a laminate of paper and aluminum foil. This laminate can help prevent ignition of the tobacco rod segment 126, which can be useful, for example, when the tobacco rod segment 126 is used as a consumable in a "heat without combustion" device, or a device of tobacco heating product, or an aerosol generating device.

The outer diameter of the rolled tobacco rod 120 may depend, for example, on the mass per unit length of the tobacco wafer 104 used, the thickness and width of the tobacco wafer 104 used, the level of compression in the lining during the formation of the bar and/or for example properties of the casing 122 and/or casing material 128 used. The outer diameter of the wrapped tobacco rod 120 may be constant during a given operating cycle of the apparatus 100. The outer diameter may be substantially in the range of 5.4mm to 7.8mm, or substantially in the range of 6.7mm to 7.8mm, For example.

Second cutter 124 is arranged to cut tobacco rod 120 (eg, after wrapper 122 has wrapped it in wrapping material 128) into segments 126 to produce tobacco rod segments 126. The second cutter 124 cuts the tobacco rod 120 transversely, to produce tobacco rod pieces 120 (i.e., the tobacco rod segments 126. The second cutter 124 may comprise, for example, a blade (not shown) whose surface The cutting blade (not shown) is arranged perpendicular to the length of the tobacco rod 120 and is controllable to cut through the tobacco rod 120. The tobacco sheet 104, the tobacco strands 112, and the tobacco rod 120 they can be advanced through the apparatus 100 at a constant speed.The second cutter 124 can be arranged to cut through the continuous tobacco rod 120 at regular intervals of time, thereby producing tobacco rod segments 126 of equal length. Tobacco rod segments 126 may have, for example, a length in the range of 12mm to 60mm For example, the tobacco rod segments 126 may have a length of 12mm, or a length of 42mm, or a 60mm length. Other lengths can 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 of tobacco strings 112. Picker 114 bundles strands 112 to form tobacco rod 120 in which each of the plurality of tobacco strands 112 is substantially unrolled, eg, substantially straight. The second cutter 124 cuts the tobacco rod 120 into segments to produce the tobacco rod segments 126 .

The apparatus 100 thus produces tobacco rod segments 126, each of which comprises a tobacco rod 130 formed by a plurality of longitudinal tobacco threads (not shown), that is, tobacco threads extending along a length direction of the tobacco rod 130, in which each of a plurality of longitudinal strands (not shown) is not substantially coiled.

The first cutter 106 may be adjustable to cut the tobacco sheet 104 on a plurality of holders 112 or not to cut the tobacco sheet 104 at all. In use, when the apparatus 100 is first used for a given tobacco wafer 104, the first cutter 106 can be adjusted so as not to cut the tobacco wafer 104 at the plurality of strands 112. The uncut tobacco wafer 104 can then be fed through funnel 114 to form a tobacco rod (not shown) of wafer 104 uncut tobacco, and the resulting rod (not shown) of wafer 104 uncut tobacco can be fed through wrapper 122 and the second cutter 124 to form segments (not shown) from the stick (not shown) of uncut tobacco sheet 104. Once the formation of the stick (not shown) of uncut tobacco sheet 104 is stable, for example, once some segments (not shown) of the stick (not shown) of uncut tobacco sheet 104 have been produced cutting, the first cutter 106 can be set to cut the tobacco sheet 104 into a plurality of strands 112 as described above, to thereby produce tobacco rod segments 126, each comprising a tobacco rod 130 formed by a plurality of tobacco strands 112 wherein each of the plurality of strands 112 is substantially unwound. The few segments (not shown) of the uncut tobacco sheet 104 rod (not shown) produced before the tobacco rod segments 126 comprising a plurality of tobacco strings 112 are produced, can be discarded. This may allow for a simpler and more consistent configuration of apparatus 100 when installing or replacing tobacco sheet 104, eg, a reel 102 of tobacco sheet 104.

Referring now to Figure 2, an apparatus 200, not falling within the scope of the appended claims, for producing tobacco rod segments 226 according to another example is schematically illustrated. Components of apparatus 200 illustrated in Figure 2 that are the same or similar to components already described with reference to Figure 1 will not be described again in detail, but are assigned the same reference numerals as in Figure 1 except that are increased by 100.

The apparatus 200 comprises a first cutter 206, a picker 214 and a second cutter 224. The first cutter 206 is arranged to cut a tobacco sheet 204 longitudinally to produce a plurality of tobacco strands 212. Picker 214 is arranged to bundle strands 212 to form a tobacco rod 220 in which each of the plurality of tobacco strands 212 is substantially unrolled, eg, substantially straight. The second cutter 224 is arranged to cut the tobacco rod 220 into segments 226 to produce the tobacco rod segments 226.

The apparatus 200 comprises a reel 202 of tobacco sheet 204. The tobacco sheet 204 is fed to the first cutter 226 from the reel 202 of the tobacco sheet 204.

The apparatus 200 comprises a tension arrangement 205 comprising a plurality (in this example, four) tension rollers 205a, 205b, 205c, 205d. Tobacco sheet 104 is fed from coil 202 onto tension rollers 205a, 205b, 205c, 205d, before being fed to the first cutter 206 in the sheet feed direction (arrow A). This can help to ensure that the tobacco sheet 204 has enough tension, eg, longitudinal tension, to be effectively cut by the first cutter 206. This can also help to smooth the tobacco sheet 104, for example, to remove any wrinkles that may be in the tobacco sheet 104.

The first cutter 206 comprises two cutting dies 206a, 206b arranged to contact opposite major surfaces of the tobacco sheet 204. Each cutting die 206a, 206b may be the same or similar to the cutter assembly 106a described above with reference to Figure 1. The cutting dies 206a, 206b are arranged to press against each other against the tobacco leaf to cut the tobacco leaf. tobacco sheet 204 longitudinally into a plurality of tobacco strands 112 (the plurality of tobacco strands 112 are distributed along a plane extending toward the page of Figure 2). For example, the cutting dies 206a, 206b may be offset relative to each other in a direction perpendicular to the tobacco leaf feeding direction (ie, offset in a direction extending toward the page of Fig. 2).

Manifold 214 comprises a funnel 214 comprising a funnel portion 216 and a stem portion 218. The axis of the funnel 114 lies in the center 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 brought together as they travel through the funnel 214 to form a tobacco rod 220.

The apparatus 200 comprises a wrapper 222 arranged to wrap the tobacco rod 220 in a wrapper material 228. Wrapper 222 can be or comprise, for example, a rod maker as known in the art, eg, a KDF (kinetic flow medium) filter rod maker to control orientation and tension of wrapper material 228 .

The wrapper 222 comprises a drive belt 246, a coil 252 of wrapper material, a lining 240, an adhesive section 242, and a heater section 244.

Drive belt 246 is a continuous strip of flexible material wound up and supported by two rollers 248a, 248b. Drive belt 246 is held taut between rollers 248a, 248b 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 can translate between the two rollers 248a, 248b. One or both of the rollers 248a, 248b are actuated to rotate (clockwise in the direction of Figure 2) about their axis, to cause the drive belt upper surface 246a to translate (from left to right). right in the sense of Figure 2).

Wrapping material reel 252 supplies a continuous sheet or web of wrapping material 228 to drive belt top surface 246a. The wrapping material 228 can be fed onto the upper drive belt surface 246a by friction of the moving surface of the upper drive belt 246a against the sheet of wrapping material 228. Accordingly, the sheet of wrapping material 228 is moved over the upper drive belt surface 246a (from left to right in the direction of Figure 2). The tobacco rod 220 is fed onto the sheet of wrapping material 228 on the top surface 246a of the drive belt. Friction between moving wrapping material 228 and tobacco rod 220 may, at least in part, cause tobacco rod 220 to feed over wrapping material 228 and thus move with material 228. wrapper. Alternatively or additionally, the tobacco rod 220 may be fed onto the moving wrapping material 228 by other means, such as one or more feed rolls or the like. In either case, the tobacco rod 220 is fed over the wrapping material 228 such that the tobacco rod 220 moves with (i.e., at the same speed as) the wrapping material 228, which in turn moves. with (ie, at the same speed as) the upper drive belt surface 246a.

Garnish 240, as known per se, folds wrapping material 228 around tobacco rod 220 as they move through garnish 240. Garnish 240 wraps wrapping material 228 around the circumference of the tobacco rod. 220 bar of tobacco. The garnish 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 itself (not shown).

The adhesive section 242 applies adhesive to the wrapping material 228 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 itself, to secure the wrapping material 228 to itself around the tobacco rod 220.

The heater section 244 heats the tobacco rod 220 to assist in the drying and/or curing of the adhesive. This helps to ensure that the adhesive is sufficiently dry/cured before the tobacco rod is cut into the 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.

In use, the first cutter 206 cuts the tobacco sheet 204 longitudinally to produce the plurality of tobacco strings 212. Collector 214 bundles strands 212 to form tobacco rod 220 in which each of the plurality of tobacco strands 212 is substantially unwound. The second cutter 224 cuts the tobacco rod 220 into segments to produce the tobacco rod segments 226.

The apparatus 200 thus produces tobacco rod segments 226, each of which comprises a tobacco rod 230 formed by a plurality of longitudinal tobacco threads (not shown), that is, tobacco threads extending along a length direction of the tobacco rod 230, in which each of the plurality of longitudinal strands (not shown) are substantially uncoiled, eg, substantially straight.

Similar to that described with reference to the apparatus 100 of Figure 1, the first cutter 206 of the apparatus 200 of Figure 2 may be adjustable to cut the tobacco sheet 104 into a plurality of longitudinal supports 112, or not to cut at all. the sheet 104 of tobacco at all. As described above, this may allow for a simpler and more consistent configuration of apparatus 200 upon installation or replacement of tobacco sheet 204, eg, a reel 202 of tobacco sheet 204.

As mentioned above, in some examples, tobacco sheet 104, 204 is provided from a reel 102, 202 of tobacco sheet 104, 204.

Referring to Figure 3, a reel 302a of tobacco sheet 304, which can be used, for example, as reel 102, 202 as described above with reference to Figures 1 and 2, can be provided from a reel 370. main sheet 304 tobacco. Mother reel 370 can be transversely cut (see dashed line 372) to produce coil 302a of tobacco sheet 304.

The main reel 307 can be cut to produce a reel 302a having a certain width W. This provides that the tobacco sheet 304 of the reel 302a has a certain mass per unit length and therefore that the segments of the reel tobacco rod (not shown in Figure 3) produced have a certain mass per unit length. Consequently, at the beginning of a manufacturing process, a desired mass per unit length of the tobacco rod segments (not shown in Figure 3) can be selected. A reel width W can then be determined as a function of the selected mass per unit length for the tobacco rod segment (not shown) and as a function of the known mass per unit area of the tobacco sheet 304 of the reel 370 major. For example, the mass per unit area (also called grammage) of the tobacco sheet 304 may be 100 g/m2. The main spool 370 can be cut to produce a coil 302a having the determined coil width W. The coil 302a can 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. Main spool 370 can be cut multiple times to produce coils 302b, 302c, 302d, 302e as desired, for example, with the same or different coil widths W. This can allow convenient and economical control over mass per unit length. of the tobacco rod segments (not shown in Figure 3) produced.

Figure 4 schematically illustrates a flowchart of a production process of tobacco rod segments 126, 226 according to one example. For example, the process can be carried out using the apparatus 100, 200 described above with reference to Figures 1 and 2, respectively. Therefore, the reference signs used in Figures 1 and 2 are also used below, as appropriate.

In step S402, the process comprises cutting a tobacco sheet 104, 204 longitudinally to produce a plurality of tobacco strings 112, 212.

The tobacco wafer 104, 204 may have a substantially constant mass per unit length, may be a reconstituted tobacco leaf, and/or may comprise glycerol.

The process may comprise, prior to step S402, providing tobacco sheet 104, 204 from a reel 102, 202 of tobacco sheet 104, 204. This may comprise providing a main reel 307 of tobacco sheet 104, 204, 304 and cutting the main reel to produce the coil 102, 202, 302a. This 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 coil width W, and cutting the main spool 307 to produce a coil 102, 202, 302a having the determined coil width W.

The process may comprise, prior to step S402, feeding the tobacco sheet 104, 204, in a sheet feeding direction A. Cutting the tobacco sheet 104, 204, 304 in S402 may then comprise cutting the sheet 104 , 204, 304 of tobacco substantially parallel to the feeding direction of sheet A.

Step S402 may comprise cutting the tobacco sheet 104, 204 with a determined number of cuts and/or a spacing between cuts. The number of cuts and/or the spacing between cuts can be determined by selecting a number of cords 112, 212 and/or a width of cords 112, 212 for the tobacco rod segments 126, 226 and determining, based on the number of selected threads and/or thread width, the cut number and/or a cut gap. Each of the plurality of threads may have a width substantially in the range of 0.25mm to 3mm, or substantially in the range of 0.5mm to 1.5mm.

In step S404, the process comprises bundling the strands 112, 212 to form a tobacco rod 112, 212 in which each of the plurality of tobacco strands 112, 212 is substantially unrolled. Step S404 may comprise bundling the strands 112, 212 to form the tobacco rod 120, 220 in which the plurality of tobacco strands 112, 212 are substantially parallel to each other and/or are each substantially straight. Step S204 may comprise bundling each of the elongated wires 112, 212 substantially transversely, toward an axis that lies at the center of the plurality of wires 112, 212, to form the bar 120. The axis toward which the wires 112, 212 may lie in a plane, the plane including the feed direction A and being perpendicular to a plane defined by the plurality of wires 112, 212 before they are bundled. Step S204 may comprise feeding the yarns 112, 212 through a funnel 114, 214 to collect the yarns 112, 212.

The process may comprise, prior to applying said cut tobacco sheet 104, 204 in step S402, feeding the tobacco sheet 104, 204 through the funnel 114, 214 to form a tobacco rod (not shown) of leaf 114 , 214 Uncut Tobacco.

In step S406, the process comprises cutting the tobacco rod 120 (of the tobacco strings 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. Wrapping material 128, 228 may be or comprise one or both of paper and aluminum foil. For example, the wrapping material 128, 228 may be a laminate of paper and aluminum foil. The tobacco rod segments 126, 226 (when wrapped) may each have an outer diameter substantially in the range of 5.4mm to 7.8mm, or substantially in the range of 6.7mm to 7.8mm. The tobacco rod segments 126, 226 may be consumables for an aerosol generating device.

Figure 5a schematically illustrates a tobacco rod segment 526 according to one example being placed in a blade heater 580 of an aerosol generating device (not shown). Specifically, Figure 5a illustrates tobacco rod segment 526 prior to being installed on blade heater 580, and Figure 5b illustrates tobacco rod segment 526 after it has been installed on blade heater 580.

Tobacco rod segment 526 can be, for example, the same or similar to tobacco rod segment 126, 226 described above with reference to Figures 1 and 2, respectively. Tobacco rod segment 526 can 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.

Referring to Figures 5a and 5b, the tobacco rod segment 526 comprises a tobacco rod 530 formed by a plurality of longitudinal tobacco threads 512, i.e., a plurality of tobacco threads 512 extending in a direction of a length of tobacco rod 530, wherein each of the plurality of longitudinal strands 512 is substantially uncoiled. The plurality of wires 512 are substantially parallel to one another, substantially straight, and each extends 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 may take the form of an elongated parallelepiped 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) from a portable aerosol generating device (not shown) and the heating of which can be controlled by a user. In some examples, blade warmer 580 may have a pointed end (not shown) to facilitate insertion of the blade warmer into tobacco rod segment 526.

The blade heater 580 can be inserted into the tobacco rod segment 526 (arrow B in Figure 5a), or similarly the tobacco rod segment 526 can be pushed over the blade heater 580, so that the blade heater 580 extends longitudinally within tobacco rod segment 526 (as shown in Figure 5b).

The plurality of longitudinal wires 512 of the tobacco rod segment 526 that are not substantially coiled allow the blade heater 580 to be easily inserted into the tobacco rod segment 526. This is because the uncoiled longitudinal wires 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 in the blade heater 580, which tobacco rod segment 526 may be a consumable of the general aerosol generating device (not shown). This can reduce damage to the tobacco rod segment 526 upon inserting the blade heater 580 and allow more consistent and correct placement of the tobacco rod segment 526 relative to the blade heater 580. This can be contrasted, for example, with a hypothetical tobacco rod segment comprising longitudinal wires that are wound, for example arranged in a helical structure: in this case, blade heater insertion would be restricted by wires crossing the path of insertion, and the blade heater can deform and compress portions of the tobacco, which can lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and can result in increased risk of damaging the hypothetical tobacco rod segment .

The plurality of longitudinal wires 512 of the tobacco rod segment 526 that are parallel to each other and/or similarly straight allow the blade heater 580 to be easily inserted into the tobacco rod segment 526. In this case, the insertion axis of the blade heater 580 is parallel to the axis of each of the longitudinal wires 512, and only a small surface area of tobacco is presented to the leading edge of the blade heater 580 when inserted. Similar to the above, this can provide convenient installation or replacement of the tobacco rod segment 526 and/or reduce damage to the tobacco rod segment 526, and/or provide more consistent and correct placement of the segment 526 of tobacco bar in relation to the blade heater 580. This can be contrasted, for example, with a hypothetical tobacco rod segment comprising randomly oriented shredded tobacco strips, or comprising wavy or corrugated tobacco leaves: in this case, inserting a blade heater can deform and compress parts of the chopped tobacco. or curled or wavy edges of the tobacco sheets, which can lead to relatively difficult and inconsistent placement of the hypothetical tobacco rod segment, and can result in an increased risk of damaging the hypothetical tobacco rod segment.

Once the tobacco rod segment 526 is inserted onto the blade heater 580 of the general aerosol generating device (not shown), the blade heater 580 can be controlled to heat up (for example, through the internal resistive heating of the blade heater 580) and thereby heating, but not burning, the tobacco strands 512. This can release components, eg, volatile components, from the tobacco strands 512. As mentioned above, the tobacco strands 512 may comprise glycerol, which may volatilize when heated with the blade heater 580 to form an aerosol.

The plurality of substantially unwound longitudinal wires 512 of the tobacco rod segment 526 establish a corresponding plurality of substantially unwound longitudinal paths 513 through the tobacco rod segment 526, between the plurality of longitudinal wires 512. These pathways 513 facilitate the transport of volatile materials released from the tobacco strands 512 upon heating (eg, volatile components of the tobacco itself or volatilized glycerol or both) through the tobacco rod segment 526 . This can reduce losses of such materials as they pass through the tobacco rod segment 526. For example, the relatively short and uninterrupted pathways 513 can reduce condensation of volatile materials back into parts of the tobacco rod segment 526. tobacco. This can be contrasted, for example, with a hypothetical tobacco rod segment comprising randomly oriented shreds of shredded tobacco (as in standard cigarettes), where the length of the path for volatilized materials to exit the tobacco rod hypothetical is relatively long. This can also be contrasted with a hypothetical tobacco rod segment comprising a plurality of coiled longitudinal wires, where the path length for the volatilized 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 aluminum foil, eg, a paper and aluminum foil laminate. The laminate of paper and aluminum foil can be useful in preventing the tobacco rod segment 526 from being ignited by the blade heater 580 .

Each of the plurality of wires 512 may have a width substantially in the range of 0.25mm to 3mm, or substantially in the range of 0.5mm to 1.5mm. Tobacco rod segment 526 may have an outer diameter substantially in the range of 5.4mm to 7.8mm, or substantially in the range of 6.7mm to 7.8mm. This may allow the use of a relatively large blade heater 580, which increases the heating surface area of the blade heater 580 and therefore increases the rate at which the tobacco can be heated and/or the amount of tobacco that can be heated with the blade heater 580.

The above examples are to be understood as illustrative examples of the invention.

For example, although in the above examples tobacco wafer 104, 204, 304 is described as a reconstituted tobacco leaf, this need not necessarily be the case, and in other examples tobacco wafer 104, 204, 304 It can be made of other materials.

Although in the above examples the manifold 114, 214 was described as a funnel 114, 214 having a circular cross section, this need not necessarily be the case, and in other examples the manifold 114, 214 may take different shapes. For example, the manifold 114, 214 can be or comprise a so-called refill jet (not shown) arranged to feed and collect the plurality of wires 112, 212 using air pressure. As another example, the funnel 114, 214 need not be circular in cross section and may, for example, have another cross section such as rectangular or square. In fact, the collector can be any suitable means to bundle the strands 112, 212 to form a tobacco rod 120, 220 in which each of the plurality of tobacco strands 112, 212 is substantially unwound.

Although in the above examples the apparatus 100, 200 comprises a wrapper 122, 222 arranged to wrap the tobacco rod 120, 220 in a wrapper 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 tobacco rod 120, 220 Tobacco (unwrapped) can be cut by the second cutter 124, 224 into segments 126, 226 to produce the tobacco rod segments 126, 226. In this example, the produced tobacco rod segments 126, 226 need not comprise wrapping material 128, 228.

It will be appreciated that Figures 1 and 2 schematically illustrate examples of apparatus for producing tobacco rod segments 126, 226 in accordance with one 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 a plurality of strings 112, 212, one or more tension rollers for tensioning the tobacco sheet 104, 204 and/or a plurality of strings 112, 212 and/or one or more drive belts for transporting the tobacco sheet 104, 204 and/or the plurality of strings 112, 212 and/or the tobacco rod 120, 220 and/or the rod segments 120, 220 tobacco.

Although in the above examples 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 not be substantially parallel to each other. For example, the tobacco strands 112, 212 may be processed to comprise a longitudinal wave or undulation or zigzag shape or the like, or indeed the tobacco sheet 104 may inherently comprise a longitudinal wave or undulation or zigzag shape or similar or be processed to have such a shape or configuration. In fact, the tobacco rod segment 126, 226 can comprise any tobacco rod 130, 530, formed by a plurality of longitudinal tobacco threads 112, 212, in which each of the plurality of longitudinal threads 112, 212 is substantially uncoiled.

Although in the above examples the tobacco rod segments 126, 226, 526 are described as being produced by the apparatus 100, 200 and/or by the process as described with reference to Figure 3, this need not necessarily be the case. and in other examples any suitable method or apparatus for producing a tobacco rod segment 126, 226, 526 comprising a tobacco rod 130, 530 formed from a plurality of longitudinal tobacco strands 112, 212, 512 each of which of the plurality of longitudinal wires 112, 212, 512 are not substantially wound, they can be used.

Although in some of the above examples the tobacco rod segments 126, 226, 526 are described as a consumable for a "heat without combustion" device or the like comprising a blade heater 580, this need not necessarily be the In this case, and in other examples, the tobacco rod segments 126, 226, 526 may be used in other devices and/or for other purposes. For example, the tobacco rod segments 126, 226, 526 can be a consumable of any aerosol generating device, eg, tobacco heating products or devices that do not necessarily comprise a blade heater 580.

Although in the above examples the tobacco sheet 102, 204, 304 is described as or comprising tobacco, for example reconstituted tobacco, this need not necessarily be the case and in other examples the sheet 104, 204, 304 may be or comprise a sheet of any aerosol generating material. The aerosol generating material may be a material which, when heated, for example, by the heater blades 580 of a general aerosol generating device, produces an aerosol. For example, the sheet of aerosol generating material 104, 204, 304 may be or comprise a flavor substrate. The flavor substrate 104, 204, 304 may comprise flavor, such as tobacco flavor or other flavor and/or may comprise glycerol or other additives or enhancers alternatively or in addition to glycerol. The flavor substrate, with or without glycerol or other additives, can be heated to produce an aerosol.

It should 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 in another substance. On the other hand, a vapor is a substance in the gas phase at a temperature below its critical temperature, which means that, for example, vapor can condense 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 vapor.

It will be appreciated that in some examples, the aerosol generating material rod segments 126, 226, 526 may be made from a sheet of aerosol generating material 102, 204, 304 as described above for a tobacco sheet 102, 204 , 304 reconstituted for example by cutting the sheet of aerosol-generating material 102, 204, 304 longitudinally to produce a plurality of strands 112, 212, 512 of aerosol-generating material; bundling the wires 112, 212, 512 to form a rod 130, 530 of aerosol-generating material in which each of the plurality of wires 112, 212, 512 of aerosol-generating material is substantially uncoiled; and cutting the aerosol generating material rod 130, 530 into segments 126, 226, 526 to produce the aerosol generating material rod segments 126, 226, 526.
