A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucolyptol, WS-3.
Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, be in the form of a solid, liquid or gel which may or may not contain an active substance and/or flavourants. In some embodiments, the aerosol-generating material may comprise an "amorphous solid", which may alternatively be referred to as a "monolithic solid" (i.e. non-fibrous). In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosol-generating material may for example comprise from about 50wt%, 6ow1% or 70wt%
of amorphous solid, to about 90wt%, 95wt% or mowt% of amorphous solid.
In some embodiments, the amorphous solid comprises: 1-60 wt% of a gelling agent;
0.1-50 wt% of an aerosol-former agent; and 0.1-80 wt% of a flavour; wherein these weights are calculated on a dry weight basis.

- 13 -In some further embodiments, the amorphous solid comprises: 1-50 wt% of a gelling agent; 0.1-50 wt% of an aerosol-former agent; and 30-60 wt% of a flavour;
wherein these weights are calculated on a dry weight basis.
In some further embodiments, the amorphous solid comprises: aerosol-former material in an amount of from about 40 to 80 wt% of the amorphous solid; gelling agent and optional filler (i.e. in some examples filler is present in the amorphous solid, in other examples filler is not present in the amorphous solid), wherein the amount of gelling agent and filler taken together is from about 10 to 60 wt% of the amorphous solid (i.e.
/o the gelling agent and filler taken together account for about 10 to 60 wt% of the amorphous solid); and optionally, active substance and/or flavourant in an amount of up to about 20 wt% of the amorphous solid (i.e. the amorphous solid comprises wt% active substance).
/5 The amorphous solid material may be formed from a dried gel. It has been found that using the component proportions discussed above means that as the gel sets, flavour compounds are stabilised within the gel matrix allowing a higher flavour loading to be achieved than in non-gel compositions. The flavour (e.g. menthol) is stabilised at high concentrations and the products have a good shelf life.
In some cases, the amorphous solid may have a thickness of about 0.015 mm to about 1.5 mm. Suitably, the thickness may be in the range of about 0.0 5mm, 0.1 mm or 0.15 mm to about 0.5 mm, 0.3 mm or 1 mm. The inventors have found that a material having a thickness of 0.2111111 is particularly suitable in some embodiments.
The amorphous solid may comprise more than one layer, and the thickness described herein refers to the aggregate thickness of those layers.
If the amorphous solid is too thick, then heating efficiency is compromised.
This adversely affects the power consumption in use. Conversely, if the amorphous solid is too thin, it is difficult to manufacture and handle; a very thin material is harder to cast and may be fragile, compromising aerosol formation in use.
Suitably, the amorphous solid may comprise from about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 Wt%, 25 Wt%, 30 wt% or 35 wt% to about 60 wt%, 55 wt%, 50 wt%, 45 wt%, 40 wt%
or 35 wt% of a gelling agent (all calculated on a dry weight basis). For example, the

- 14 -amorphous solid may comprise 1-60 wt%, 5-60 wt%, 20-60 wt%, 25-55 wt%, 30-50 wt%, 35-45 wt%, 5-45 wt%, 10-40 wt% or 20-35 wt% of a gelling agent.
The amorphous solid may comprise a gelling agent. The gelling agent may comprise one or more compounds selected from cellulosic gelling agents, non-cellulosic gelling agents, guar gum, acacia gum and mixtures thereof.
In some embodiments, the gelling agent comprises a hydrocolloid. In some embodiments, the gelling agent comprises one or more compounds selected from the io group comprising alginates, pectins, starches (and derivatives), celluloses (and derivatives), gums, silica or silicones compounds, clays, polyvinyl alcohol and combinations thereof. For example, in some embodiments, the gelling agent comprises one or more of alginates, pectins, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethylcellulose, pullulan, xanthan gum guar gum, carrageenan, agarose, acacia gum, fumed silica, polydimethylsiloxane (PDMS), sodium silicate, kaolin and polyvinyl alcohol. In some cases, the gelling agent comprises alginate and/or pectin, and may be combined with a setting agent (such as a calcium source) during formation of the amorphous solid. In some cases, the amorphous solid may comprise a calcium-crosslinked alginate and/or a calcium-crosslinked pectin.
The cellulosic gelling agent can be selected from the group consisting of:
hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethylcellulose (CMC), hydroxypropyl methylcellulose (HPMC), methyl cellulose, ethyl cellulose, cellulose acetate (CA), cellulose acetate butyrate (CAB), cellulose acetate propionate (CAP) and combinations thereof.
In some embodiments, the gelling agent comprises (or is) one or more of hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose (HPMC), carboxymethylcellulose, guar gum, or acacia gum.
In some embodiments, the gelling agent comprises (or is) one or more non-cellulosic gelling agents, including, but not limited to, agar, xanthan gum, gum Arabic, guar gum, locust bean gum, pectin, carrageenan, starch, alginate, and combinations thereof. In preferred embodiments, the non-cellulose based gelling agent is alginate or agar.

- 15 -In some embodiments, the amorphous solid comprises alginate and pectin, and the ratio of the alginate to the pectin is from 1:1 to 10:1. The ratio of the alginate to the pectin is typically >1:1, i.e. the alginate is present in an amount greater than the amount of pectin. In examples, the ratio of alginate to pectin is from about 2:1 to 8:1, or about 3:1 to 6:1, or is approximately 4:1.
In some embodiments, the amorphous solid comprises filler in an amount of from 1 to 30 wt% of the amorphous solid, such as 5 to 25 wt%, or 10 to 20 wt%. In examples, the amorphous solid comprises filler in an amount greater than 1 wt%, 5 wt%, or 8 wt% of io the amorphous solid. In examples, the amorphous solid comprises filler in an amount less than 4 ovvt%, 30 wt%, 20 Wt%, 15 Wt%, 12VVt% 10VVt%, 5w1%, or ivvt% of the amorphous solid. In other examples, the amorphous solid does not comprise filler.
In examples, the amorphous solid comprises gelling agent and filler, taken together, in /5 an amount of from about 10 wt%, 20 wt%, 25 wt%, 30 wt%, 35 wt%, 40 wt%, 45 wt%, 50 wt%, 55 wt% or from about 60 wt%. In examples, the amount of gelling agent and filler, taken together, is no more than 85 wt%, 80 wt%, 75 wt%, 70 wt%, 65 wt%, or no more than 60 wt% of the amorphous solid. In examples, the amorphous solid comprises gelling agent and filler, taken together, in an amount of from about 20 to 60 20 wt%, 25 to 55 wt%, 30 to 50 wt%, or 35 to 45 wt% of the amorphous solid.
The filler, if present, may comprise one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulphate, magnesium carbonate, and suitable inorganic sorbents, 25 such as molecular sieves. The filler may comprise one or more organic filler materials such as wood pulp, cellulose and cellulose derivatives. In particular cases, the amorphous solid comprises no calcium carbonate such as chalk.
In some examples which include filler, the filler may be fibrous. For example, the filler 30 may be a fibrous organic filler material such as wood pulp, hemp fibre, cellulose or cellulose derivatives. Without wishing to be bound by theory, it is believed that including fibrous filler in an amorphous solid may increase the tensile strength of the material.
35 In some examples, the amorphous solid does not comprise tobacco fibres.
In particular examples, the amorphous solid does not comprise fibrous material.

- 16 -In some embodiments, the amorphous solid may comprise from about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt% or 10 wt% to about 80 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt% or 2 5w1% of an aerosol former material (all calculated on a dry weight basis). For example, the amorphous solid may comprise 0.5-40 wt%, 3-35 wt% or 25 wt% of an aerosol former material.
The aerosol former material may act as a plasticiser. If the content of the plasticiser is too high, the amorphous solid may absorb water resulting in a material that does not /o create an appropriate consumption experience in use. If the plasticiser content is too low, the amorphous solid may be brittle and easily broken.
In some embodiments, the aerosol former included in the amorphous solid comprises one or more polyhydric alcohols, such as propylene glycol, triethylene glycol, 1 ,3-butanediol and glycerin; esters of polyhydric alcohols, such as glycerol mono-, di- or triacetate; and/or aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.
In some cases, the aerosol former material comprises one or more compound selected from erythritol, propylene glycol, glycerol, triacetin, sorbitol and xylitol.
In some cases, the aerosol former material comprises, consists essentially of or consists of glycerol.

91 mm, e.g. from about 79 mm to about 88 mm), "long" or "super-king"
(typically in the range 91 ¨ 105 mm, e.g. from about 94 mm to about 101 mm) and "ultra-long"
(typically in the range from about no mm to about 121 mm).
They are also named according to the product circumference: "regular" (about

23 ¨ 25 mm), "wide" (greater than 25 mm), "slim" (about 22 - 23 mm), "demi-slim"
(about 19 - 22 mm), "super-slim" (about 16 ¨ 19 mm), and "micro-slim" (less than about 16 mm).

Accordingly, an article in a king-size, super-slim format will, for example, have a length of about 83 mm and a circumference of about 17 mm.

The at least one elongate strip io located on the outer surface of the first material 7 has a width which partially surrounds the first material. Figure 1 shows a cross-sectional view of the article 1 and therefore only shows two elongate strips lo of amorphous solid material 9 partially surrounding /5 the first material 7. However, it will be appreciated that more than two elongate strips lo may partially surround the first material 7. Furthermore, in some embodiments, the plurality of elongate strips lo of amorphous solid material 9 may be distributed such that they at least partially surround the first material 7 but have gaps between adjacent elongate strips 10.
In some embodiments, the second material 8 may disposed within the first material 7, as illustrated in Figure 1. That is, the amorphous solid material 9 may be disposed in the first material 7 such that it extends through the first material 7 and is at least partially surrounded by the first material 7. As shown in Fig. 1, the plurality of elongate strips lo of amorphous solid material 9 may be disposed in the first material 7 such that the elongate strips lo extend through the first material 7 and are at least partially surrounded by the first material 7. This may aid the delivery of the substance to be delivered to a user.

Furthermore, features and components of the alternative article 50 that are the same as the features and components of the above described article 1 will retain the same terminology and reference numerals.
However, the second embodiment of the article 50 differs from the first embodiment of is the article 1 in that the heat displacement collar 3 is omitted and that the component that comprises the amorphous solid material 9 is the filter component 2.
Furthermore, in the second embodiment of the article 50, the first material 7 of the filter component 2 comprises a filtration material.

25 The filter component 2 described above may form the filter component 2 of an article for a non-combustible aerosol delivery system or a combustible delivery system.
It will be appreciated that in other embodiments, the component comprising the amorphous solid material 9 maybe the heat displacement collar component 3.
Referring to Figure 3, a schematic side view of a non-combustible aerosol provision device 100 for generating aerosol from the aerosol generating portion component 4 of an article 1 of Figure 1 is shown. The non-combustible aerosol provision device 100 generates aerosol from an aerosol generating medium/material such as the aerosol material of a consumable no, as described above. In broad outline, the device 100 may be used to heat a replaceable article 110 comprising the aerosol generating medium or

- 33 -filter segment, for instance an article 1, 50 as illustrated in Figure 1 or Figure 2 or described elsewhere herein, to generate an aerosol or other inhalable medium which is inhaled by a user of the device loo. The device loo and replaceable article no together form a system.
The device loo comprises a housing 102 (in the form of an outer cover) which surrounds and houses various components of the device loft The device wo has an opening 104 in one end, through which the article no may be inserted for heating by a heating assembly. In use, the article no may be fully or partially inserted into the io heating assembly where it may be heated by one or more components of the heater assembly.
The device loo may also include a user operable element 112, such as a button or switch, which operates the device loo when pressured. For example, a user may turn on is the device loo by operating the switch 112.
The device loo may also comprises an electrical component, such as a socket/port 114, which can receive a cable to charge a battery of the device loft For example, the socket 114 may be a charging port, such as a USB charging port.
Referring briefly to Figure 4, an amorphous solid material 9 is shown. The amorphous solid material 9 is in the form of a ribbon 120. The ribbon 120 of amorphous solid material 8 is wound into a reel 121 which may be located on a bobbin (not shown) for being fed into an assembly apparatus (not shown), as will be described in more detail hereinafter. The ribbon 120 of amorphous solid material 9 is a mass of amorphous solid material 8 that has not been cut into a plurality of elongate strips.
Referring briefly now to Figure 5, an amorphous solid material 9 is shown which has been cut into a plurality of elongate strips 10. The amorphous solid material 9 may be cut into a plurality of elongate strips 10 by a cutting device (not shown), as will be described in more detail hereinafter. As illustrated in Figure 5, the plurality of elongate strips 10 of amorphous solid material 8 are twisted into a rope 130. The rope 130 of elongate strips 10 of amorphous solid material 9 may have a greater tensile strength than an untwisted plurality of elongate strips 10 or a ribbon 120 of amorphous solid material 9, which may aid in the manufacturing process. The rope 130 of amorphous

- 34 -solid material 9 may be wound onto a bobbin (not shown) and fed directly from the bobbin into the assembly apparatus (not shown).
Referring to Figures 1 to 5, and the above description, it will be understood that the amorphous solid material 9 may be provided in the component 2, 3, 4 in any of the above mentioned forms, i.e. a ribbon, a plurality of elongate strips, or a rope of twisted elongate strips. Where more than one amorphous solid material 9 is present, it will be understood that the amorphous solid materials 9 may be present in more than one form.
Referring briefly to Figure 6, a plurality of elongate strips 10 of amorphous solid material 9 are shown wound onto a bobbin 140. The plurality of elongate strips 10 are wound randomly onto the bobbin 140 after a ribbon has been strip-cut, i.e. cut into elongate strips. The plurality of elongate strips 10 of amorphous solid material 9 may be is unwound from the bobbin 140 and fed directly into an assembly apparatus (not shown) during manufacture of a component.
Referring now to Figure 7, a bobbin 150 is shown with a plurality of elongate strips 10 of amorphous solid material 9 wound onto the bobbin 150. In the present embodiment, the plurality of elongate strips 10 of amorphous solid material 9 are wound spirally onto the bobbin i5o. That is, the plurality of elongate strips 10 of amorphous solid material 9 are wound around the bobbin 150 at an angle to the plane extending perpendicularly to the rotational axis of the bobbin i5o. The plurality of elongate strips 10 of amorphous material 9 are wound from one end of the bobbin to the other end to form a layer 151 of elongate strips 10 on the bobbin 150.
In between each layer 151 of elongate strips 10 of amorphous solid material 9 is a sheet 152. The sheet 152 is configured to prevent elongate strips 10 of amorphous solid material 9 in one layer 151 sticking to elongate strips 10 of amorphous solid material 9 in an adjacent layer. The sheet 152 is sacrificial. That is, the sheet 152 is removed from the amorphous solid material 9 during the manufacturing process. The sheet 152 may be formed from, for example, but not limited to, paper.
Referring now to Figure 8, an exemplary cutting device 160 configured to cut a ribbon 161 of amorphous solid material 9 into a plurality of elongate strips 10 of amorphous solid material 9 is shown. The cutting device 160 comprises at least one rotary cutting

- 35 -knife 162 connected to a rotatable shaft 163. In the present embodiment, the shaft 163 extends substantially horizontally from a frame 164 of the cutting device 160 and the at least one rotary knife extends substantially vertically from the shaft 163.
Preferably, the cutting device 160 comprises a plurality of cutting knives 162. The plurality of cutting knives 162 cut the ribbon 161 of amorphous solid material 9 into a plurality of elongate strips lo of amorphous solid material 9.
The plurality of cutting knives 162 are spaced apart in a direction parallel to the longitudinal axis of the shaft 163. The plurality of cutting knives 163 are spaced apart by /o a distance equal to the desired width of the elongate strips 10.
Preferably, the cutting knives 162 are spaced apart equally so that the width of the plurality of elongate strips lo are equal in order to provide a more consistent delivery of the substance to be delivered.
/5 The cutting device 160 further comprises a supporting member 165 configured to support the weight of the amorphous solid material 8 as it is cut by the rotary knives 162. The supporting member 165 may be a plate extending generally horizontally from the frame 164. The supporting member 165 may be slightly curved to maintain the amorphous solid material 9 under tension during the cutting process.
The support member 165 is located above the rotary shaft 163. The support member 165 comprises at least one aperture or slit 166 configured to allow the at least one rotary knife 162 to extend through the support member 165. The support member 165 may comprise one slit 166 per knife 162.
In some embodiments, the cutting device 160 may comprise additional rollers 167, 168.
The additional rollers 167, 168 may transport the amorphous solid material 9 through the cutting device 160. The additional rollers 167, 168 may also keep the amorphous solid material 9 under tension as it passes through the cutting device 160.
The cutting device 160 may comprise one roller 167 upstream of the cutting knives 162 and one roller 168 downstream of the knives 162.
The cutting device 160 may comprise a spreading mechanism. The spreading mechanism is configured to spread the plurality of elongate strips 10 of amorphous solid material 9. The spreading mechanism spreads the plurality of elongate strips lo before the plurality of elongate strips 10 are incorporated into the first material 7 of the

- 36 -article 1, 50. Advantageously, this reduces bunching of the plurality of elongate strips.
That is, the spreading mechanism reduces the special concentration or grouping of the elongate strips 10 in the first material 7 and helps to keep them spaced apart in the first material 7.
In one example, the spreading mechanism may comprise a roller having a curved surface. That is, a roller may have a curved surface in the form of a concave curve across its length. For example, the surface at the midpoint of the length of the roller may have a smaller radius than the surface at the ends of the length of the roller. The roller which io forms the spreading mechanism may be a roller 168 downstream of the rotary cutting knife 162 in the cutting device 160.
In another embodiment, a roller which forms the spreading mechanism may be provided just upstream of an apparatus for assembling a component of the article 1, 50.
/5 This has the advantage of reducing the amount of time available for the plurality of strips 10 to bunch or entangle before entering the apparatus. In some embodiments, the spreading mechanism may be formed by a device other than a concave roller.
In some embodiments, the cutting device 160 may be provided as a distinct apparatus.
20 The cutting device 160 may be used to cut a ribbon 161 of amorphous sheet material 9 into a plurality of elongate strips 10 of amorphous solid material 9 which is then wound onto a bobbin, as illustrated in Figures 6 and 7. Alternatively, the cutting device 160 may be used to cut a ribbon 161 of amorphous sheet material 9 into a plurality of elongate strips 10 of amorphous solid material 9 online. That is, the plurality of 25 elongate strips 10 of amorphous solid material 9 leaving the cutting device 160 may be transported directly into the component assembly apparatus (not shown).
In some embodiments, the cutting device 160 may be provided as a module that is configured to be attached to an existing component assembly apparatus (not shown). It 30 will be understood that the cutting device 160 shown in Figure 8 is only exemplary and that other cutting devices may be used to cut a ribbon of amorphous solid material into a plurality of elongate strips.
In one embodiment, a ribbon 161 of amorphous solid material 9 may have a width of 18 35 mm. The ribbon 120 is wound on a reel and/or bobbin. The ribbon 120 is then positioned to be fed into a cutting device 160, as shown in Fig. 8. In such an

- 37 -embodiment, the cutting device 160 may comprise seven cutting knives 162. The seven cutting knives 162 are configured to cut the ribbon 161 into eight elongate strips 10. The seven cutting knives 162 are evenly spaced such that the ribbon 161 is cut into eight elongate strips 10 having a width of about 2.25 mm each.
In embodiments where the first material 7 is a reconstituted tobacco material, the reconstituted tobacco material may be drawn through the cutting device 160 together with the ribbon 161 of amorphous solid material 8. Thus, both the first and second materials, 7, 8 could be cut into a plurality of elongate strips at the same time.
In some embodiments, the width of the reconstituted tobacco material sheet may be the same as the width of the ribbon 161 of amorphous solid material 9. In other embodiments, the width of the reconstituted tobacco material sheet may be wider than the width of the ribbon 161 of amorphous solid material 9. In such embodiments, some is cutting knives 162 may cut both the reconstituted tobacco material sheet and the amorphous solid material 9, and some cutting knives may only cut the reconstituted tobacco material sheet.
Referring now to Figure 9, a perspective side view of a part of an assembly apparatus 170 for manufacturing components for an article as described above. The assembly apparatus 170 comprises a first material transporter 171. In the present embodiment, the first material transporter 171 is a cut rag tobacco transporter, although it will be appreciated that in an alternative embodiment, the first material transporter 171 may be a recon tobacco transporter which may transport reconstituted tobacco in the form of sheets or strips. The first material transporter 171 may comprise a conveyor belt. The first material transporter 171 may feed the first material 7 towards a garniture 172 of the apparatus 170. The assembly apparatus 170 further comprises a wrapping material feed 173 comprising rollers 174 which feed wrapping material 175 into the garniture 172. The apparatus 170 further comprises a second material transporter 176 configured to feed the second material into the garniture 172. The apparatus 170 may comprise the cutting device 160 or bobbins 140, 150 described above.
A method of manufacturing an article 1, 50 described above comprises the steps of preparing a first material for formation into a component 2, 3, 4 of an article 1, 50. For example, the first material 7 may be a tobacco material which may be prepared by the usual steps of drying and cutting, etc. The method further comprises the step of

-38 -transporting the first material 7 continuously through an assembly apparatus 170. For example, the first material 7 may be transported towards a garniture along a conveyor belt. The method further comprises the step of adding at least one continuous amorphous solid material 9 to the first material 7.
By adding the amorphous solid material 9 to the first material 7 just before the component is formed, the known steps of shredding the amorphous solid material and adding it to a blending cylinder with the first material 7 can be avoided.
Avoiding the shredding and blending steps for an amorphous solid material 9 is advantageous for io several reasons. Firstly, less of the volatile substances to be delivered contained in the amorphous solid material are lost because the amorphous solid material is subject to less kinetic excitation. Secondly, by controlling the delivery of the amorphous solid material 9 to the first material 7, a more homogeneous component 2, 3, 4 can be produced. The method allows for the variation in the substance to be delivered between individual components 2, 3, 4 to be less than 5%, and in some case less than 3%. In addition, there is less chance of the amorphous solid degrading than in a blending cylinder. Finally, safety concerns regarding combustion of released substances to be delivered in the blending cylinder are avoided.
The disclosed method of forming a component comprising amorphous solid material 9 enables a manufacturer to produce an end product with a higher content of the substance to be delivered. For example, it has been proven that such a method enables a component to be produced comprising three times more of the substance to be delivered, menthol, with the same amount of amorphous solid material 9, than with the known method. Advantageously, this means that either products with higher content of the substance to be delivered can be produced, or the amount of substance to be delivered that is required to produce a product with a given content is reduced due to the reduced losses of the substance to be delivered during the manufacturing process which can reduce manufacturing costs.
In one method, a single amorphous solid material 9 is to be added to the first material 7. Such a method comprises the step of unwinding a ribbon 120 of amorphous solid material 9 from a bobbin and transporting the ribbon 120 directly into the assembly apparatus.

- 39 -In one method, a plurality of elongate strips lo of amorphous solid material 9 are to be added to the first material 7. One such method comprises the step of unwinding a ribbon 120 of amorphous solid material 9 from a bobbin and cutting the ribbon 120 of amorphous solid 9 into a plurality of elongate strips 10. The cutting step may be performed by a cutting device 160 as described above.
The method of forming an article comprising a plurality of elongate strips lo of amorphous solid material 9 may further comprise the step of feeding the plurality of elongate strips lo of amorphous solid material 9 directly from the cutting device 160 io into the assembly apparatus 170. In one method, the plurality of elongate strips lo of amorphous solid material 9 is fed from the cutting device 160 directly into the assembly component 170 immediately before a component forming device, such as a garniture.
Such a method is known as online cutting.
/5 The method of forming an article comprising amorphous solid material 9, in ribbon 120 or elongate strip lo form, may further comprise the steps of transporting the first material 7 and the amorphous solid material 9 through the component forming device, forming an endless component, wrapping the endless component in a wrapper, and cutting the endless component into discrete components.
The step of cutting the endless component releases tension in the amorphous solid material 9 such that the amorphous solid material 9 reduces in length into the ends of the component such that the ends of the amorphous solid material is obscured from view.
Where the first material 7 is cut-rag tobacco, it is envisaged that the plurality of elongate strips lo of amorphous solid material 9 may be incorporated into a component in one of at least two ways.
In the first method, the tobacco is 'air-lifted' onto the conveyor belt 171 and fed into the garniture section 172 where the wrapping material 175 is applied. The plurality of elongate strips 10 are fed into the tobacco rod forming section of a component maker.
That is, the plurality of elongate strips lo are fed into a part of the maker which gathers and forms the tobacco rod. Therefore, the plurality of elongate strips lo are fed in alongside the tobacco material. The position at which each of the plurality of elongate strips 10 meet the tobacco material on the conveyor belt 171 will determine the location

-40 -that each of the plurality of elongate strips 10 are likely to be in in the final rod component.
In the second method, the plurality of elongate strips lo are fed alongside the wrapping material 175 as the wrapping material 175 is fed into the garniture 172.
Therefore, the plurality of elongate strips 10 are incorporated into the final component adjacent to the wrapping material 175. In some embodiments, this method may result in the plurality of elongate strips 10 being located substantially circumferentially in the final component.
Alternatively, where the first material 7 comprises a plurality of elongate strips of tobacco material or filter material, the plurality of elongate strips 10 of amorphous solid material 9 may be added to the first material 7 in the same way that a thread would be added to the first material, i.e. streamed into the filter material or tobacco strips and is positioned within the flow of filter material or tobacco strips.
As previously mentioned, in some embodiments, the first material 7 and the second material 8 are fed from separate bobbins and aligned and combined upstream of the cutting device 160 before simultaneously being cut into a plurality of strips.
It has been found that the positioning of the ribbon 120 on the first material 7 can influence the positioning of the plurality of strips of second material 8 in the final aerosol generating component portion 4.
For example, referring to Figures lo to 11, it can be seen that the placement of the ribbon 120 of second material 8 centrally on the sheet of first material 7 causes the plurality of strips of second material 8 to cluster together in one position.
This cluster of the plurality of strips of second material 8 is generally positioned at a random distance from the centre of the aerosol generating component portion 4.
In another example, referring to Figures 12 to 13, it can be seen that the placement of the ribbon 120 of second material 8 in two sections that are separated by a gap on the sheet of first material causes the plurality of strips of second material 8 to cluster together in two distinct groups. These clusters of the plurality of strips of second material 8 are generally positioned at a random distance from the centre of the aerosol generating component portion 4 and at random angular positions relative to each other.

- 41 -Therefore, by spreading out the second material 8 into a plurality of smaller ribbons 120 on the sheet of first material 7, the cut plurality of strips of second material 8 are more evenly spaced from each other on the sheet of first material 7 and a more uniform .. distribution of the plurality of strips of second material 8 in the first material 7 can be achieved in the final aerosol generating component portion 4, when the portion 4 is formed using the method of simultaneously strip cutting the first and second materials 7, 8. In some embodiments, the plurality of ribbons 120 of second material 8 may be fed from a plurality of bobbins. Alternatively, a single ribbon may be cut into smaller /o ribbons which are positioned relative to the sheet of first material 7 before being fed into the strip cutter 160.
The placement of the second material 8 relative to the first material 7 may be determined using an apparatus 200 similar to the one shown in Figure 14. The /5 apparatus 200 comprises a first bobbin 201 around which the first material 7 is wrapped and a second bobbin 202 around which the second material 8 is wrapped.
The apparatus 200 is configured to perform simultaneous cutting of the first and second materials 7, 8 using a cutting device 160 similar to that already described.
20 In this embodiment, the second bobbin 202 may have at least one degree of freedom, indicated by the arrows in Figure 14. That is, the second bobbin 202 may be able to move parallel to the rotational axis of the bobbin 202 in order to change the position of the second material 8 relative to the first material 7.
25 The apparatus may further comprise at least one rotatable guide drum 203 provided between the second bobbin 202 and the cutting device 160. The at least one guide drum 203 may determine the material path of the second material 8 between the second bobbin 202 and the cutting device 160. The at least one guide drum 203 may have at least one degree of freedom. That is, the at least one guide drum 203 may be able to 30 move parallel to the rotational axis of the guide drum 203 in order to change the position of the second material 8 relative to the first material 7. By moving the second bobbin 202 and the guide drums 203, the position of the strips of second material 8 in the final rod can be varied.
35 When two second bobbins 202 are used with their own respective guide drums 203, the two ribbons 120 of second material 8 can be moved relative to the first material 7 and

-42 -each other. Thus, a gap may be present between the two ribbons of second material 8 when they are aligned with the first material 7.
In an alternative embodiment, shown in Figure 15, the first and second materials 7, 8 may be configured to be cut separately. In such an arrangement, the apparatus may have a first cutting device 301 configured to cut the first material 7 and a second cutting device 302 to cut the second material. Furthermore, the at least one guiding drum 203 may be located after the second cutting device 302 and before the gatherer.
/o In this embodiment, the second bobbin 202 may have at least one degree of freedom.
That is, the second bobbin 202 may be able to move parallel to the rotational axis of the bobbin 202 in order to change the position of the second material 8 relative to the first material 7. In addition, in this embodiment, the second cutting device 302 may have at least one degree of freedom. That is, the cutting disks of the second cutting device 302 /5 may be able to move parallel to the rotational axis of the second cutting device 302 in order to change the width of the individual strips of second material 8.
Furthermore, the at least one guide drum 203 may have at least one degree of freedom.
In the embodiment illustrated in Figure 15, a first guide drum 304 may be able to move 20 parallel to the rotational axis of the guide drum 304 in order to change the position of the strips of the second material 8 relative to the first material 7. In addition, a second guide drum 305 has at least two degrees of freedom. That is, the second guide drum 305 may be able to move parallel to the rotational axis of the guide drum 305 in order to change the position of the strips of the second material 8 relative to the first material 25 7, and in the other direction perpendicular to the width of the first material 7, i.e.
towards and away from the first material 7, to effect the final position in the radial direction within the rod. Thus, a gap may be present between the two adjacent clusters of plurality of strips of second material 8 when they are aligned with the first material 7.
30 Finally, the method may further comprise combining the component with other components to form the article.
In an alternative method of forming an article comprising a plurality of elongate strips of amorphous solid material 9, instead of performing online cutting, the method 35 may comprise the step of winding the plurality of elongate strips 10 of amorphous solid material 9 onto a bobbin, after the cutting step, in preparation for adding the plurality

-43 -of elongate strips 10 of the amorphous solid material 9 to the first material 7 in the assembly apparatus 170. In one method, the winding step may further comprise the step of spirally winding the plurality of elongate strips 10 of amorphous solid material 9 onto a bobbin, after the cutting step, in preparation for adding the plurality of elongate strips 10 of the amorphous solid material 9 to the first material 7 in the assembly apparatus 170. In one method, the spiral winding step may further comprise placing sheets between the layers of elongate strips 10 of amorphous solid material 9.
In an alternative method, a ribbon of amorphous solid material and first material /o simultaneously onto the same bobbin. The ribbon of amorphous solid material and first material may be co-wound. That is, the two materials may be layered on each other.
Therefore, when moving from the centre of the bobbin in a radial direction the layers may alternate.
/5 The method may further comprise the steps of unwinding the ribbon of amorphous solid material and first material from the bobbin simultaneously. When removed from the bobbin the materials will form a two layer ribbon. The ribbon of amorphous solid material and first material may be cut simultaneously. In some embodiments, the first material may be reconstituted tobacco.
In one method, the step of winding the plurality of elongate strips 10 of amorphous solid material 9 may further comprise twisting the plurality of elongate strips 10 of amorphous solid material 10 to form a rope 130 to be fed into the assembly apparatus 170 before winding the plurality of elongate strips 10 onto the bobbin 140, 150.
