Description

The present invention relates to a device and method for applying, with an interval, the linings of the first material onto the web of the second material. In particular, but not only, the present invention relates to a device and method for applying, with an interval of heat-conducting lining, to a web of paper-like material for use in the manufacture of smoking articles.

Throughout the description, it is assumed that the term smoking articles means not only ordinary smoking products in which the base, usually tobacco, is burned, but also other smoking products, such as heated smoking products, in which the base is not burned, but heated and which are based on the formation aerosol from a heated base, and smoking products based on sublimation.

This method and device can be used in a number of other applications. For example, in the manufacture of packaging, some consumer goods may need to be applied at intervals of one packaging material to another packaging material. In the manufacture of smoking articles, it may be necessary to apply, with an interval of one material, to a web of paperlike material, such as tissue paper or tipping paper, for example, to add flavors, such as menthol, or for labeling. One material can be polypropylene.

However, this method and device is particularly useful in the manufacture of heated smoking articles, such as the products described in U.S. Patents δδ 4,714,082, ϋδ 5,819,751 and ϋδ 5,040,551, sublimation-based smoking articles, such as the products described in pending patent application ΑΘ2009 / 022232, and heated cigarettes, such as cigarettes manufactured by K.1. KepopoIk Tobasso Sotrapu under the trademarks Rtet1et® and Yesyrke®.

According to a first aspect of the invention, there is provided a device for applying, with an interval, a lining of a first material onto a web of a second material, comprising means for introducing a web of a first material including clamping means for clamping a web of a first material, the clamping means being provided for moving the web of a first material with constant speed when the web of the first material is introduced; adhesive applicator for applying glue to the canvas of the first material; a cutting device comprising at least one knife for cutting a sized web of first material in order to form a glued overlay of the first material; means for introducing a web of a second material; and a transfer drum for applying glued patches of a first material onto a web of a second material.

The term glue, as used herein, is used to refer to any substance that provides for sticking anything, including adhesives, pastes, cements and other sticky substances.

In one embodiment, in which the device is intended for use in the manufacture of smoking articles, the first material is a heat-conducting material, and the second material is a paper-like material.

Preferably, the glue applicator is adapted to apply, at intervals, the glue areas to the web of the first material. This is preferred since the adhesive does not have to cover the entire web of the first material, so that the adhesive is applied only to some part of each patch of the first material. In addition, it is preferred because the adhesive can not be applied along the lines along which the cutting device will cut the web of the first material. This prevents the cutting device from clogging with glue. The interval between the adhesive areas can be equal to the required size of the lining of the first material. Alternatively, the glue applicator may be configured to apply a continuous stream of glue to the web of the first material.

In the embodiment in which the device is intended for use in the manufacture of smoking articles, the device may further comprise a second adhesive applicator for applying glue to a web of paper-like material for attaching a web of paper-like material with spaced heat-conducting pads to the element in the finished smoking article.

Preferably, the second adhesive applicator is located downstream of the transfer drum. Alternatively, the second adhesive applicator may be located along the front of the transfer drum. Preferably, the second adhesive applicator is adapted to apply the lines of glue to the thermally conductive pads spaced apart on the web of paper-like material. In a variant of the finished smoking article, which includes a combustible heat source, the second adhesive applicator may be configured to apply adhesive lines to heat conducting pads spaced on the web of paper-like material to attach each heat conductive pad to the combustible heat source in the finished smoking article.

Preferably, the clamping means is provided for moving the web of the first material upon its introduction at a speed depending on the length of each patch of the first material and the interval between the linings of the first material on the web of the second material. More preferably, the clamping means are provided for moving the web of the first material, upon its insertion, at a speed depending on the ratio of the length of each heat-conducting strip to the length between the plates.

In the embodiment in which the device is intended for use in the manufacture of smoking articles, the clamping means is preferably provided for moving the web of thermally conductive material when it is introduced at a speed depending on the ratio of the length of each thermal conductor to the interval between the thermal conductive plates on the paper-like material. Even more preferably, the clamping means is provided for moving the web of heat-conducting material when it is introduced at a speed depending on the ratio of the length of each heat-conducting lining to the length of the finished smoking article without a mouthpiece. Thus, the distance between the glued pads of the first material on the web of the second material can be adjusted by the feed speed of the web of second material, which is set by the clamping means.

In an embodiment of the device, the clamping means comprises two movable pressure rollers which are capable of being pressed together in order to control the speed at which the web of the first material is supplied. The device may also comprise an additional movable roller or rollers to eliminate any sagging of the first material in the web.

The device may further comprise a cam for repeated acceleration of the web of the first material downstream of the clamping means. This allows you to unevenly distribute taped lining on the canvas of the second material. Thus, the size and control of the cam can determine the separation of taped linings on the web of the second material. The cam may be a mechanical cam or an electronic cam.

In one embodiment, the device further comprises perforating means for perforating the web of the second material. In the embodiment in which the device is intended for use in the manufacture of smoking articles, the punching means can be configured to perforate the web of the second material in the direction corresponding to the direction along the circumference of the finished smoking article. Alternatively, the perforating means may be configured to perforate the web of the second material in a direction corresponding to the longitudinal direction of the finished smoking article.

In one embodiment, the cutting device is adapted to receive the sized canvas of the first material at a constant speed. In this embodiment, preferably the knife or knives of the cutting device are evenly spaced. Alternatively, the knife or knives of the cutting device may be unevenly spaced. Preferably, the cutting knives move with a certain speed relative to the glued web of the first material, which contributes to the formation of a neat cut.

In an alternative embodiment, the glued web of the first material is made with the possibility of repeated acceleration when the glued web of the first material enters the cutting device. This can be achieved by placing the cutting device in the course after the cam. In this embodiment, preferably the knife or knives are unevenly spaced in accordance with the acceleration of the web of the first material. Alternatively, the knife or knives may be evenly spaced. Preferably, the cutting knives move with a certain speed relative to the glued web of the first material, which contributes to the formation of a neat cut.

In this embodiment, the lining of the first material and lining of the third material can be applied independently on the canvas of the second material. Both types of overlays can have any arrangement and size. The first and third materials may be the same or different. Cloth from the third

- 2 017706 material can be a band, strip or tape. The third material may be a flexible web of material having any suitable width, length and thickness.

According to a first aspect of the invention, there is provided a device for applying, with an interval, linings of a first material onto a web of a second material, this device comprising: means for introducing a web of a first material comprising clamping means for clamping a web of a first material, the clamping means being provided for moving the web from the first material at a constant speed when the web of the first material is introduced; adhesive applicator for applying glue to the canvas of the first material; means for introducing the web of the second material; and cutting and transporting means, made with the ability to take a glued web of the first material, cut the glued web of the first material to form glued linings of the first material and apply the glued linings of the first material to the web of the second material. The device may further comprise a cam located in front of the cutting and transporting means, the cam being adapted to repeatedly accelerate the glued web of the first material when it is fed into the cutting and displacing means, ensuring the formation of two different intervals between the glued linings of the first material on the web from the second material.

A variant of the first object is also proposed, namely, a device for applying, with an interval, thermally conductive patches onto a web of paper-like material for use in the manufacture of smoking articles, this device comprising means for introducing a web of thermally conductive material, including clamping means for clamping the web of thermally conductive material clamping means are made to move a web of heat-conducting material at a constant speed when inserting a web of heat conductor yachting material; glue applicator for applying glue to the canvas - from a heat-conducting material; a cutting device for cutting a glued web of thermally conductive material to form glued linings of thermally conductive material; means for introducing a web of paper-like material and a transfer drum for applying glued linings of thermally conductive material onto a web of paper-like material.

Preferably, the clamping means is provided for moving the web of heat-conducting material when it is inserted at a speed depending on the ratio of the required length of each heat-conducting lining to the distance between the heat-conducting lining on the web of paper-like material. Thus, the distance between the glued patches of thermally conductive material on a web of paper-like material can be adjusted by means of the feed speed of the web of thermally conductive material, which is set by the clamping means.

In one embodiment, the device further comprises perforating means for perforating a web of paper-like material.

Preferably, the step of applying the sized linings of the first material to the web of the second material comprises applying the sized linings of the first material spaced on the web of the second material. Glued lining of the first material can be evenly spaced on the canvas of the second material. Alternatively, taped lining of the first material may be unevenly spaced on the canvas of the second material.

The features of one subject matter may also be applicable to another subject matter.

Below, the invention will be described, by way of example only, with reference to the accompanying drawings.

FIG. 1 shows a smoking article based on sublimation; in fig. 2a, 2b and 2c are the steps performed by the device according to the invention; in fig. 3 is a schematic view of the first embodiment of the device; in fig. 4 is a schematic view of a second embodiment of the device; in fig. 5 is a schematic view of a third embodiment of the device.

As described above, the invention provides an apparatus and method for applying, with an interval of overlays of the first material, to a web of second material. One particularly useful application of the apparatus and method of the invention is the application of thermally conductive pads, such as aluminum foil, onto a web of paper-like material, such as tissue paper or tipping paper, for use in the manufacture of heated smoking articles, such as the products described in US Pat. 4,714,082, 5,819,751 and 5,040,551, smoking products based on sublimation, such as the products described in the pending patent application \ νϋ 2009/022232, and heated cigarettes, such as cigarettes produced by K.1. Kuopoyk Tobasso Sotrupa under the brand names Rgetter® and Yesirke®.

A sublimation smoking article described in ν02009 / 022232 is shown in FIG. 1. The smoking article 101 comprises a combustible heat source 103, a base 105 for generating aerosols, and an extended expansion chamber 107, which is wrapped in an outer paper wrapper 111, and a mouthpiece 109 in a coaxial alignment end-to-end. The combustible heat source 103 is cylindrical and contains a central channel 113 for the air flow, which continues in the longitudinal

- 4 017706 direction through heat source 103. The base 105 for generating the aerosol is located downstream of the combustible heat source 103 and is a cylindrical insert of homogenized tobacco material 115 containing glycerin as a means to form an aerosol and limited to an insert wrapper 117. The heat-conducting element 119, consisting of an outer wrapper of aluminum foil, surrounds and is in contact with the back of the combustible heat source 103 and the adjacent front of the base 105 for generating aerosols. The elongated expansion chamber 107 is located downstream of the base 105 for generating aerosols and is a cylindrical cardboard tube 121 with open ends. The mouthpiece 109 is located along the extended extension chamber 107 and is a cylindrical insert of acetylcellulose tow 123, limited by a wrap 125 for the filter insert. In this embodiment, the outer paper wrapper 111 includes a perforation 127 around its periphery, located directly in front of the heat-conducting element 119. The smoking article 101 is limited to tipping paper 129.

FIG. 1 illustrates one embodiment of a particular sublimation-based smoking article. However, various modifications are possible. For example, if desired, one or more of the following modifications may be made. The heat source may contain additional or spaced channels for the air flow. The basis for generating the aerosol may contain any suitable material. Additional bases may also be provided for generating the aerosol, for example including other tobacco material or flavors. A protective material may be contained between the heat source and the basis for generating the aerosol. Instead of one expansion chamber, two shorter expansion chambers may be provided. Any suitable mouthpiece may be contained or the mouthpiece may be excluded altogether. You can exclude tipping paper. The perforation can be eliminated or can be located next to the heat-conducting element, so that the user can see the aluminum foil through the perforations. Alternatively, the perforation may continue in the longitudinal direction, rather than around the periphery of the smoking article.

The device and method according to the invention can be used in the manufacture of smoking articles in accordance with FIG. 1 for applying aluminum foil to the paper web to form heat-conducting elements 119.

FIG. 2a, 2b and 2c illustrate the steps of one embodiment of the method of the invention for applying aluminum foil to a paper web to form heat-conducting elements 119 on smoking articles, such as the smoking article illustrated in FIG. one.

In accordance with FIG. 2a, glue areas 201 are periodically applied to the web of the first material in the form of an aluminum foil web 203. In this embodiment, the width 501 of the blade 203 corresponds to the circumference of the finished smoking articles. In this embodiment, the frequency of the glue sections 201 corresponds to the required length of each heat-conducting element 119 in the finished smoking article (see FIG. 1). Alternatively, continuous flow of glue may be applied to the aluminum foil web 203.

In accordance with FIG. 2b a sheet of aluminum foil is cut into individual glued patches of the first material in the form of aluminum patches 205, each of which will form a heat-conducting element 119 in the finished smoking article. Each pad 205 includes a taped area 207. In this embodiment, the width 501 of each pad 205 corresponds to the circumference of the finished smoking articles. In this embodiment, the height 503 of each patch 205, which is equal to the periodicity of the adhesive sections, corresponds to the required length of the heat-conducting element 119 in the finished smoking article (see FIG. 1).

In accordance with FIG. 2c, aluminum patches 205 are applied to the paper web 209. FIG. 2c, the glued areas 207 are shown in dashed lines, since the linings are rotated so that each glued area is on the back surface of the aluminum lining 205 to glue it to the paper web 209. In addition, an additional glue line 210 is applied to each aluminum lining 205. This additional line of glue will be used to attach the aluminum lining 205 to the heat source 103. In accordance with FIG. 1, the glue line 210 is preferably located between the front end of the aluminum and the rear end of the heat source, with the possibility of attaching an aluminum lining to the downstream end of the heat source 103. In this embodiment, the width 501 + 505 of the paper web 209 corresponds to the circumference of 501 finished smoking articles plus the allowance 505 for gluing. Perforation lines 211 may also be applied, corresponding to perforations 127 in the finished smoking article (see FIG. 1).

FIG. 2c, the overlays 205 are unevenly spaced on the paper web 209. In fact, there are two different intervals 507 and 509 between the overlays. This arrangement is particularly preferred, as will be described below. It is widely used in the manufacture of smoking articles to form double-length rods of smoking material. Then, these double-length rods are cut into two, a mouthpiece with a double-length filter is inserted into the middle and secured with a mouthpiece paper, and then the whole double-length smoking article is cut to get

- 5 017706 two smoking articles. In this device, each rod of double the length of the smoking material must contain elements in one half, arranged in reverse order with respect to elements in the other half. This is done in such a way that when a mouthpiece with a filter is inserted in the middle, two corresponding smoking articles are obtained. Thus, the aluminum pads 205 on the paper web should have two different spacing, as shown in FIG. 2c. The first interval 507 corresponds to the interval between aluminum lining in a single rod of double length. The second interval 509 corresponds to the interval between the heat-conducting plates on adjacent rods. The intervals between the overlays 205 on the paper web 209 will be further described below.

FIG. 3 is a schematic view of a first embodiment of the device according to the invention. The device 301 comprises a rear flap 303, means for inserting a sheet of aluminum foil in the form of a device 305 for supplying aluminum foil from the coil 307 of feeding aluminum foil, a moving roller 309 for aluminum foil, clamping means in the form of pressure driving rollers 311, fixed rollers 313, glue applicator 315, a cutting device in the form of a drum 317 for cutting overlays, means for inserting a paper web in the form of a paper feeding device 319 and a paper feeding drum 321, a transfer drum in the form of a drum 323 for transferring paper clutches and device 325 security issue. The embodiment illustrated in FIG. 3 also includes a perforating means 327 and an additional adhesive applicator 329. FIG. 3 A thick line is used to image a sheet of aluminum foil, a thin line is used to image a paper sheet and a thin line with spaced thick sections is used to image paper with aluminum foil overlays.

The operation of the device shown in FIG. 3 is as follows. A sheet of aluminum foil is fed from the supply coil 307 to the supply device 305. The aluminum foil web is then fed around the movable roller 309, which, as shown by the arrow, is able to move up and down in order to influence the tension of the web of foil. The aluminum foil web is then fed in the direction of the arrows through the stationary rollers 313 to the pressure rollers 311. The stationary rollers 313 may also be known as freely rotating floating rollers. The pressure rollers 311 drive the web of the first material at a corresponding feed rate, and the movable roller 309 eliminates any sagging in the incoming web. More specifically, two clamping drive rollers can be pressed against each other in order to press, drive and fix the incoming web with the ability to dose the first material at an appropriate speed. The movable roller 309 provides tension in the web by removing any slack. In this embodiment, the rate of supply of the incoming aluminum sheet is determined in accordance with the ratio of the length of the pad to the length of the smoking article without a mouthpiece. This aluminum web feed rate is set by pressure rollers 311 in accordance with this ratio.

After the pressure rollers 311, the glue applicator 315 applies glue areas 201, or glue lines, or a continuous or intermittent stream of glue to the web, as shown in FIG. 2a The adhesive applicator 315 may continuously be in contact with the web as it moves. If glue patches are required, rather than a continuous flow of glue, this can be established, for example, by periodically changing the supply of glue. This can be done electronically.

Then, the glued aluminum foil web is moved to the drum 317 to cut the linings and the drum 323 to transfer the linings. The drum 317 for cutting overlays comprises at least one knife parallel to the axis of the drum for cutting a sheet of aluminum foil substantially perpendicular to its length. When the glued aluminum foil web is moved between the drum 317 to cut the linings and the drum 323 to transfer the linings, the canvas is cut into separate aluminum linings 205, as shown in FIG. 2b. Preferably, suction is applied at the entrance to the drum 323 to transfer the liner and the linings to the drum for transporting the linings. The knife preferably moves along the aluminum foil web when it cuts it, thereby providing a neat cut. In other words, the drum 317 for cutting pads and the drum 323 for transferring the pads preferably move at the same speed in the zone of their contact. The individual linings (taped side out) are moved in a clockwise direction around the drum to transfer linings. Preferably, at the outlet of the drum 323 for transferring the linings, air is blown out, which helps to remove the linings from the drum. Paper is fed to the reel 312 for feeding paper from the paper feeding reel (not shown). When the paper comes into contact with the individual aluminum lining 205 on the drum 323 for transferring the lining, the lining is applied to the paper. The air that is blown out at the exit of the drum 323 for transferring the linings facilitates the application of the linings to the paper. The glue can then be dried using heaters (not shown).

After the overlays have been applied to the paper, the punching means 327 forms a perforation in the paper web (as indicated by the reference numeral 211 in FIG. 2c). This forms a perforation in the goto

- 6 017706 of the smoking article (see reference numeral 127 in FIG. 1). As already mentioned, the perforation may continue along the longitudinal axis of the smoking article, and not around the circumference of the smoking article, in which case the perforation means 327 can be designed accordingly. Perforation may allow the user to remove a portion of the paper overwrap from a heat source. This prevents burning of the outer paper wrapper when the smoking article is lit. Alternatively, the perforation may be applied in a separate unit containing the knife and the opposing drum, located either above or in the direction after the transfer drum 323.

The glue applicator 329 is used to apply an additional line of glue to each patch (see reference numeral 210 in FIG. 2c). The glue line can be used to attach the lining to a heat source in order to hold the elements together and ensure the integrity of the smoking article. If the perforation continues in the longitudinal direction of the smoking article, the user can remove the paper overwrap on top of the heat source by breaking along the perforation from the closest end. A glue line will prevent the removal of all paper outer wrappers. The glue applicator 329 can also be used to apply any adhesive needed for further steps in the manufacturing process. To seal the glue applicator 329, the movable plug comes in contact with the paper, pressing one lining against the glue gun outlet, so that the glue does not dry out.

An additional assembly (not shown) may also be provided for applying printing marks or other marks on the paper web in front of the feed device 319 or in the area of the additional adhesive applicator 329.

FIG. 4 shows a schematic view of a second embodiment of the device according to the invention. Where appropriate, reference numerals are used as in FIG. 3. In addition, as in FIG. 3, a thick line is used to image a sheet of aluminum foil, a thin line is used to image a sheet of paper and a thin line with spaced thick sections is used to image a sheet of paper coated with aluminum foil. The device 301 'includes a rear flap 303, a device 305 for supplying aluminum foil from the coil 307 of feeding aluminum foil, a movable roller 309 for aluminum foil, pressure driving rollers 311, fixed rollers 313, adhesive applicator 315, drum 317 for cutting linings, device 319 for paper feed, paper feed drum 321, lining transfer drum 323, paper dispenser 325, punching means 327 and additional adhesive applicator 329. However, in this embodiment, the device further includes an electronic cooler Choke 401 (schematically shown in Fig. 4).

The operation of the device shown in FIG. 4, is as follows. A sheet of aluminum foil is fed from the supply coil 307 to the supply device 305. Then a sheet of aluminum foil is fed around a rolling roller 309, which is able to move up and down to influence the tension in the sheet of foil. The aluminum foil web is then fed in the direction of the arrows through the stationary rollers 313 to the pressure rollers 311. The pressure roller rollers 311 drive the web of the first material at a corresponding feed rate, and the mobile roller 309 eliminates any slack in the incoming web. After the pressure rollers 311, the aluminum foil web is fed through the cam 401 behind the glue applicator 315, which applies glue sections 201, or glue lines, or a continuous or intermittent glue stream to the fabric, as shown in FIG. 2a

Then, the glued aluminum foil web is moved to the drum 317 to cut the linings and the drum 323 to transfer the linings. When a taped aluminum foil web passes between the drum 317 to cut the linings and the drum 323 to transfer the linings, the canvas is cut into separate aluminum linings 205, as shown in FIG. 2b. In addition, suction can be used at the inlet of the drum 323 for transferring the linings to interlock the web and the linings with the drum. In addition, the drum 323 for the transfer of plates and the drum 317 for cutting, preferably, move with the same speed in the contact zone, which provides a neat cut. The individual linings (taped side out) are moved in a clockwise direction around the drum to transfer linings. In addition, at the outlet of the drum 323 for transporting the linings, air can be blown out, which helps to remove the linings from the drum. The paper is fed into the drum 321 for supplying paper from the reel for feeding paper (not shown). When the paper comes into contact with the individual linings 205 on the drum 323 for transferring the linings, the linings are applied to the paper, as shown in FIG. 2c. After the overlays are applied to the paper, the punching agent 327 may form a perforation in the paper web. The glue applicator 329 may be used to apply an additional line of glue 210 or any glue needed for further steps in the manufacturing process. An additional assembly (not shown) may also be provided for applying printed or other markings to the paper web in front of the feed device 319 or in the area of the additional adhesive applicator 329.

In the embodiment illustrated in FIG. 3, the rate of supply of incoming aluminum

- 7 017706 lottery is determined in accordance with the ratio of the length of the lining to the length of the smoking product without a mouthpiece. The supply speed is set in the pressure rollers 311. In addition, the faster the paper web moves, the faster the linings are applied in order to maintain the same pitch (frequency) of the application. In this case, at a constant speed, the aluminum foil pads will be evenly spaced on the paper (ie, not as shown in Fig. 2c).

However, in order to provide a variable frequency, the speed of the aluminum sheet must be constantly variable. In the embodiment illustrated in FIG. 4, the pressure rollers 311 feed the web at a constant speed, and the electronic cam 401 provides a variable periodicity, similar to that shown in FIG. 2c. With the help of the cam 401, the tension in the web periodically changes. The pressure rollers 311 are configured to adapt a constant feed rate in the pressure rollers 311 to a varying feed speed in the drum 323 for transferring the linings. Moving roller 309 eliminates any slack. Reverse movement, which could lubricate the glued lining, is absent. The cam 401 adjusts the speed of the transfer drum in such a way that the aluminum web is pulled back no faster than the speed at which the transfer drum moves it forward. Thus, the supply speed of the incoming aluminum sheet is set by the pressure driving rollers 311 and is determined according to the ratio of the length of the pad to the length of the smoking article without the mouthpiece, while the cam 401 provides two spacing between the plates, and the movable roller 309 eliminates sagging in the web when the tension changes .

This allows the device to create a paper web with overlays similar to that shown in FIG. 2c, with alternating large and small intervals between the plates.

The programmed cam profile on the pressure rollers 311 can be changed by changing the size of two different intervals (507 and 509) between the pads. If more than two different intervals are required, then the cam can be adjusted accordingly.

FIG. 5 is a schematic view of a third embodiment of the device according to the invention. Where appropriate, reference numerals are used as in FIG. 3 and 4. In addition, as in FIG. 3 and 4, a thick line is used to image the aluminum foil web, a thin line is used to image the paper web, and a thin line with spaced thick sections is used to image the paper web with aluminum foil overlays. The device 301 comprises a rear flap 303, an aluminum foil supply device 305 from an aluminum foil supply coil 307, a movable roller 30 9 for aluminum foil, pressure driving rollers 311, stationary rollers 313, adhesive applicator 315, paper cutter drum 317 , a paper feed drum 321, a lining transfer drum 323, a paper extraction means 325, a punching means 327, and an additional adhesive applicator 329. In this embodiment, the device further includes a mechanical cam mechanism 601, comprising a fixed roller 603 and a movable roller 605.

The operation of the device shown in FIG. 5, is as follows. A sheet of aluminum foil is fed from the supply coil 307 to the supply device 305. Then a sheet of aluminum foil is fed around a rolling roller 309, which is able to move up and down, controlling the tension in the sheet of foil. Then the sheet of aluminum foil is fed in the direction of the arrows through the stationary rollers 313 to the clamping drive rollers 311. After the clamping drive rollers 311, the sheet of aluminum foil is fed through the cam mechanism 601.

The cam mechanism 601 comprises a first fixed wheel 603 with a protrusion 603a and a second wheel 605 on the movable frame 605a. The stationary wheel 603 rotates and, when the protrusion 603a abuts against the frame 605, the frame 605a and the roller 605 move up and away from the roller 605 (see arrow). This sets a longer path for the incoming web. Then, as the stationary wheel continues to rotate, the protrusion 603a rotates beyond the frame 605a, while the frame 605a and the roller 605 are moved back down to their original positions (see arrow). This returns the incoming canvas to its original trajectory. The rate of supplying the incoming aluminum blade is determined according to the ratio of the length of the lining to the length of the smoking product without the mouthpiece, while the pressure rollers drive the web from, the cam mechanism provides two spacing between the lining, and the movable roller 309 eliminates slack in the web when tension is changing.

After the cam mechanism 601, a sheet of aluminum foil is fed behind a glue applicator 315, which applies glue sections 201, or glue lines, or a continuous or intermittent jet to the sheet, as shown in FIG. 2a In order to avoid smearing the glue, the aluminum web is not pulled back through the glue gun outlet. Then, the glued aluminum foil web is moved to the drum 317 to cut the linings and the drum 323 to transfer the linings. When a taped aluminum foil web passes between the drum 317 to cut the linings and the drum 323 to transfer the linings, the canvas is cut into separate aluminum linings 205, as shown in FIG. 2b. In addition, at the entrance to the drum 323 for transporting the linings, you can use suction to couple the web and the linings with the drum. Besides,

- 8 017706 drum 323 for transporting the pads and cutting drum 317 preferably move at the same speed in the contact zone, so that the knife moves along the aluminum foil web and provides a neat cut. The individual linings (taped side out) are moved in a clockwise direction around the drum to transfer linings. In addition, at the outlet of the drum 323 for transporting the linings, air can be blown out, which helps to remove the linings from the drum.

Paper is fed to the paper feed drum 321 from a paper feed reel (not shown). When the paper comes into contact with the individual aluminum lining 205 on the drum 323 for transferring the lining, the lining is applied to the paper, as shown in FIG. 2c. After the overlays are applied to the paper, the punching agent 327 may form a perforation in the paper web. The glue applicator 329 may be used to apply an additional line of glue 210 or any glue needed for further steps in the manufacturing process. An additional assembly (not shown) may also be provided for applying printed or other markings to the paper web in front of the feed device 319 or in the area of the additional adhesive applicator 329.

The mechanical cam mechanism 601 in the embodiment illustrated in FIG. 5 provides a variable periodicity similar to that shown in FIG. 2c. When the cam mechanism is actuated, the incoming web is repeatedly accelerated. The tension in the canvas along the cam mechanism 601 remains constant. The pressure rollers 311 are configured to accommodate a constant feed rate on the pressure rollers 311 with a variable speed on the drum 323 for transferring the linings.

This allows this device to produce a paper web with overlays, similar to that shown in FIG. 2c, with alternating large and small intervals between the overlays, by rotating the cam. The operation of the cam mechanism 601, in particular, the size and speed of rotation of the cam, can be changed to change the size of two different intervals (507 and 509) between the overlays. If more than two different intervals are required, then additional cams can be used as needed.

FIG. 3, 4 and 5 the distance between the knives on the drum for cutting must be calculated with high accuracy in order to correctly cut the blade.

The invention has been described with regard to the application of spacing of linings from a first material onto a web of a second material for use in the manufacture of smoking articles. However, the invention can be used wherever lining of one material on another material is required. One application of this invention is the packaging of some consumer goods, for example chewing gum packaging. Both materials can be a band, strip or tape. Both materials are predominantly sheet-like and can be of any suitable length, width and thickness. Cloths of both materials can preferably be wound on a roller or drum. The first and second materials can be different materials or the same material.
