Description

Technical Field

[0001] The present invention relates to a method for producing rod-shaped products (especially filter rods or filter rod segments or segmented products or multi-segmented products) for the tobacco processing industry, wherein the rod-shaped products have a plurality of rod-shaped product segments arranged successively in the longitudinal direction of the rod-shaped products.

[0002] The invention also relates to a device for producing rod-shaped products for the tobacco processing industry, in particular filter rods or filter rod segments or segmented products or multi-segmented products. The invention also relates to an arrangement of a plurality of rod-shaped multi-segmented products for the tobacco processing industry in a package, in particular a box. Background Art

[0003] For the production of multi-segment products for the tobacco industry, different rod segments are provided in the form of basic rods or rod-shaped segments and are assembled into a rod-shaped multi-segment product by means of a roller machine.

[0004] In machines in the tobacco processing industry, in particular filter inserting machines or machines for producing alternative smoking products such as heat-not-burn products or electronic cigarettes, conveyor drums are used to transport cigarettes, filter elements or components thereof.

[0005] During the production of cigarettes, filters and filter cigarettes or so-called heat-not-burn products or electronic cigarettes, the conveying of the above-mentioned rod-shaped objects is usually carried out in modern production machines in the tobacco processing industry by means of a conveyor roller, the side of the conveyor roller or the roller body of the conveyor roller is provided with grooves or receiving grooves for receiving the rod-shaped objects, so as to be used for transversely axially conveying the rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes).

[0006] It is known from the prior art to produce basic rods and to feed them via a feed module into a processing process on a roller machine, or to connect a roller machine directly to a rod-making machine in order to directly further process the rod segments.

[0007] For example, EP 1691633 B1 discloses a drum machine for the tobacco processing industry for producing multi-segment products, wherein the drum machine comprises a plurality of feed modules which provide rod-shaped segments and feed them into a transport segment.

[0008] It is also known that when producing cigarettes, in particular filter cigarettes, secondary air channels in the form of holes or perforations are introduced in the area of ​​the filter, through which secondary air is supplied to the smoke during smoking. The purpose of this is to supply a relatively large secondary air flow, which should be kept as constant as possible in a predetermined ratio to the total flow leaving the cigarette. This ratio is called the total air permeability. It is already known that cigarettes are provided with holes, that is, they are perforated, for example by rolling along a rolling surface provided with needles.

[0009] In order to keep a brand of cigarettes as stable as possible with regard to condensate, nicotine and carbon monoxide (CO) in the smoke, and with regard to the smoking behavior recorded by the smoker (puff preference, number of puffs and puff resistance), the partial air permeability that makes up the total air permeability, which is composed of the filter air permeability and the rod air permeability, must be kept as constant as possible.

[0010] During the mass production of cigarettes at a filter inserting machine, perforations consisting of holes are introduced into the wrapping material or wrapping band of the rod-shaped product in the finished filter cigarettes using a perforating device. In particular, uniform perforations are introduced into the wrapping band of the filter cigarettes, so that when smoking, the wrapping band has a predetermined, desired air permeability, so that secondary air is sucked into the wrapping band due to the introduced perforation pattern, and the specific gravity of nicotine and condensate in the smoke is influenced by the secondary air. In particular, a laser beam is used as coherent radiation to introduce perforations into the wrapping band, so that very precise and constant areas with the desired air permeability are produced in the wrapping of the smoking article.

[0011] By forming perforations in the wrapping material of the rod-shaped product, the wrapping is provided with an area having a predetermined air permeability so that a certain amount of fresh air is mixed into the smoke each time the cigarette is puffed. The wrapping material or wrapping band of these products is generally made of paper, wherein the wrapping material or wrapping band is perforated at predetermined intervals to produce the desired air permeability. In the case of filter cigarettes, it is generally common to perforate the wrapping paper sheet or wrapping band at the filter end on the mouthpiece side.

[0012] In the area of ​​the mouthpiece end, a region with a desired air permeability (the so-called air permeability region) is provided for the smoking article, which provides the article with a predetermined (total) air permeability so as to be able to meet predetermined values ​​of nicotine and condensate in the smoke of the smoking article or filter cigarette (the smoking article or filter cigarette has such a region with the desired air permeability). Summary of the invention

[0013] The object of the present invention is to provide perforated multi-piece products, in particular heat-not-burn products, with a predetermined air permeability when producing multi-piece products on a multi-piece product manufacturing machine in the tobacco processing industry, wherein the expenditure for this purpose should be kept as low as possible.

[0014] This object is achieved by a method for producing rod-shaped products (especially filter rods or filter rod segments or segmented products or multi-segment products) for the tobacco processing industry, wherein the rod-shaped products have a plurality of rod-shaped product segments arranged successively in the longitudinal direction of the rod-shaped products, wherein product groups having at least two or three or four or more than four rod-shaped product segments are assembled or assembled, wherein the rod-shaped product segments are arranged successively in the longitudinal direction of the product group, and wherein at least one product segment or a plurality of, especially all product segments of the product group are wrapped by a wrapping belt, wherein the product groups are conveyed successively (preferably only) in the transverse axial direction, wherein after the respective rod-shaped product groups have been assembled, the product groups are individually inspected at a conveying component (especially a conveying roller) in the conveying direction of the product group conveyed along the transverse axial direction by a pneumatic inspection device, wherein the (especially individual) actual suction resistance of the respective product group is acquired by the pneumatic inspection device, and then at another conveying component (especially a conveying roller) in the conveying direction of the product group conveyed along the transverse axial direction,

[0015] (i) providing the wrapping band of the one or the product section or the product sections of each product group with an individual perforation pattern, in particular a perforation correction pattern, in the region of the product section or in the region of one (in particular only one) product section, by means of a perforation device, in particular a laser device, according to the determined (in particular individual) actual suction resistance of the respective product group,

[0016] Or (ii) based on the actual suction resistance of each corresponding product group (especially individually) obtained, a separate perforation pattern, especially a perforation correction pattern, is preferably set on a wrapping band of the product segment added to the corresponding product group by a perforation device (especially a laser device) in the area of ​​the added product segment.

[0017] The invention is based on the idea of ​​providing a constant air permeability for the finished or ready-to-use rod-shaped products during a production period or throughout a production batch when producing rod-shaped products such as multi-section products or heat-not-burn products. To this end, the rod-shaped products are conveyed, for example, in a transverse axial direction at a multi-section product manufacturing machine, wherein it is possible that after the assembly of the rod-shaped product group (as a rod-shaped intermediate product), the corresponding (especially individual) actual suction resistance is first acquired by a pneumatic inspection device, and then after further conveying in the transverse axial direction at the multi-section product manufacturing machine, the pneumatically inspected product group is supplemented by at least one additional product segment by a corresponding provision module for additional product segments to form another (especially longer) product group (as another rod-shaped intermediate product or as a rod-shaped final product), which is then wrapped separately by a wrapping belt, and in a further step, a perforation pattern, especially a perforation correction pattern, is provided by a perforation device according to the acquired (especially individual) actual suction resistance of the product group, in order to achieve a constant air permeability of the product group.

[0018] The method according to the invention makes it possible to provide a constant air permeability (for all manufactured multi-section products) for rod-shaped multi-section products, for which the flow resistance to air fluctuates greatly in the respective product sections. Since the flow resistance to air in the product sections is not constant, the corresponding actual suction resistance of the product group with the product sections is determined in order to subsequently form a rod-shaped multi-section product with a constant air permeability by means of a perforating device.

[0019] In another design of the method according to the present invention, it is provided that a multi-segment product (such as a heat-not-burn product) is assembled with a plurality of product segments having a fixed final length and wrapped with a wrapping belt, wherein the manufactured multi-segment product for consumption or use is inspected by a pneumatic inspection device with respect to the corresponding (especially individual) actual suction resistance, and in a subsequent step, a corresponding individual perforation pattern, especially a perforation correction pattern, is set for the multi-segment product by a perforation device so that the finished multi-segment product has the same or almost the same and constant (total) air permeability.

[0020] Another advantage of the method is that, for each multi-section product, a corresponding perforation pattern is determined according to the actual suction resistance of the corresponding multi-section product obtained, so as to provide each multi-section product with a predetermined, in particular constant or almost constant air permeability.

[0021] The actual suction resistance of the corresponding product group is obtained, for example, on an inspection roller, on which the one pneumatic inspection device (for a row of product groups arranged and conveyed successively along the transverse axis) or the multiple pneumatic inspection devices (for two or more rows of product groups arranged side by side, which are arranged and conveyed successively along the transverse axis) are arranged.

[0022] The method provides that the transported product groups are pneumatically checked by (especially software-based) product tracking during their transverse transport along the multi-stage product manufacturing machine and are provided with individual perforation patterns, especially perforation correction patterns.

[0023] Furthermore, it is provided within the scope of the invention that, when conveying two (or more) rows of product groups arranged side by side, which are arranged and conveyed coaxially one after the other, for each row of product groups, the respective actual suction resistance of the product groups of the two rows is determined independently of one another. Furthermore, in a further development, the perforating device arranged downstream is also operated independently of one another for these rows. In particular, the perforating device is designed as a laser device, i.e., for example, a laser radiation source is designed for each row of product groups.

[0024] Furthermore, one embodiment of the method is characterized in that before being conveyed to the pneumatic inspection device, the assembled product groups each have at least one or only one product segment for a perforation pattern or the perforation pattern to be set. Thus, the pre-perforated product groups can be conveyed to the pneumatic inspection device in each case. Within the scope of the invention, for example, the product segments conveyed to the product groups by the supply module can be pre-perforated by a supply module for one type of product segment.

[0025] Furthermore, in a further development of the method, it is preferred that when or during the assembly of the product groups, the product segments of the product groups to be assembled or assembled are not perforated in the transverse axial conveying direction before being conveyed to the pneumatic inspection device and / or the wrapping tape of the product groups is not perforated. After the assembly of the product groups, if necessary, after wrapping with the wrapping tape upstream of the pneumatic inspection device, the product groups are not perforated in this case.

[0026] Furthermore, one embodiment of the method is characterized in that at least one further product segment (preferably not provided with a perforation pattern or provided with a perforation pattern) is added to the product group downstream of the pneumatic inspection device for the product group and upstream of the perforation device in the conveying direction of the product group, and / or at least one further product segment (preferably not provided with a perforation pattern) is added to the product group downstream of the perforation device in the conveying direction of the product group. It is provided within the scope of the invention that after the respective product group (as an intermediate product) has been individually perforated, the further product segment is added to the respective perforated product group, for example by one or more supply modules for the further product segment, so that a ready-to-use multi-segment product, such as a heat-not-burn product, is subsequently produced in a further production step, for example at a multi-segment product manufacturing machine.

[0027] According to another aspect of the method, at least one additional product segment is added to the product group downstream of a pneumatic inspection device for the product group and upstream of a perforation device along the conveying direction of the product group, and after the additional product segment is added to the corresponding product group, the added additional product segment is provided with a perforation pattern, in particular a perforation correction pattern, by the perforation device.

[0028] Here, in one embodiment of the method, it is advantageous that, upstream of the perforating device, the added further product sections of the product group are wrapped with a wrapping belt, wherein in particular the wrapping belt of the further product sections of the product group is provided with a perforation pattern, in particular a perforation correction pattern, by the perforating device.

[0029] Furthermore, in a development, the method is characterized in that, downstream of the perforating device in the conveying direction of the group of products, the group of products provided with the perforation pattern formed by the perforating device has an almost constant or almost equal suction resistance.

[0030] In addition, a favorable design of the method also stipulates that, in order to assemble a product group, the product segment is not provided with or does not have a perforation pattern upstream of the pneumatic inspection device and / or upstream of the perforation device along the conveying direction of the product segment; or in order to assemble the product group, at least one product segment of the product group is provided with a perforation pattern upstream of the pneumatic inspection device and / or upstream of the perforation device along the conveying direction of the product segment.

[0031] In particular, in the method, it is preferred that the actual suction resistance of the corresponding product group obtained is transmitted to the adjusting device, in particular, a (preferably central) machine control unit, and after the actual suction resistance of the corresponding product group is transmitted, the corresponding actual suction resistance is compared with a predetermined (preferably common to these product groups) target value for the suction resistance of the product group by the adjusting device, and when the corresponding actual suction resistance of each product group deviates from (in particular is lower than) the target value in a manner that is lower than or higher than a predetermined deviation limit value, the adjusting device transmits corresponding control instructions to the perforation device to form separate perforation patterns, in particular perforation correction patterns, in the corresponding product groups.

[0032] Furthermore, in an advantageous embodiment of the method it is provided that the assembled group of articles is at least partially arranged or provided with a wrapping tape upstream of the pneumatic testing device.

[0033] In addition, according to one aspect, the method is characterized in that two (preferably parallel) rows of product groups - which are arranged and assembled side by side and spaced apart from each other in the longitudinal direction - are conveyed respectively to a pneumatic inspection device and respectively to a perforation device along the transverse axial direction, preferably by a roller arrangement structure with multiple conveying rollers, wherein in particular, the two rows of assembled product groups with product segments have been or are to be constructed to be identical, especially symmetrical.

[0034] In addition, the task is solved by a device for producing rod-shaped products (especially filter rods or filter rod segments or segmented products or multi-segmented products) for the tobacco processing industry, wherein the rod-shaped products have multiple rod-shaped product segments arranged successively in the longitudinal direction of the rod-shaped products, wherein the device has multiple providing modules for providing product segments, and the product segments are used for rod-shaped product groups and product groups having multiple product segments and at least one wrapping belt, wherein the device also has a roller arrangement structure for transversely conveying rod-shaped product groups, wherein the rod-shaped product groups respectively have at least two or three or four or more rod-shaped product segments, wherein a pneumatic inspection device is arranged in the roller arrangement structure along the transverse axial conveying direction of the product group, for obtaining the (preferably individual) suction resistance of each product group, and during the pneumatic inspection A perforating device (especially a laser device) is arranged downstream of the device for individually perforating the product groups using a perforation pattern (especially a perforation correction pattern), wherein the perforating device is constructed to: (i) set a separate perforation pattern, especially a perforation correction pattern, for a product segment of each product group or the wrapping band of the multiple product segments in the area of ​​the product segment or in the area of ​​one (especially only one) product segment according to the (preferably individual) actual suction resistance of each corresponding product group obtained, or (ii) set a separate perforation pattern, especially a perforation correction pattern, for a wrapping band of a product segment added to the corresponding product group by a perforating device (especially a laser device) preferably in the area of ​​the added product segment according to the (especially individual) actual suction resistance of each corresponding product group obtained.

[0035] In order to assemble product groups to be inspected, for example at a multi-segment product manufacturing machine, a supply module for single or multiple product segments (the product segments are used for product groups) is arranged upstream of the pneumatic inspection device so that after the product groups to be inspected are assembled, they can be transported transversely and axially to one or more inspection devices using conveying rollers of a roller arrangement structure.

[0036] Furthermore, one embodiment of the device is characterized in that at least one further supply module for supplying a further product section for the product group is arranged downstream of the pneumatic inspection device for the product group and upstream of the perforation device in the conveying direction of the product group.

[0037] In the device, it is further preferred that a wrapping device is provided downstream of the pneumatic inspection device for the product group and upstream of the perforating device in the conveying direction of the product group for wrapping the product section or another product section added to the respective product group.

[0038] Furthermore, in one embodiment of the method, it is advantageous if a supply module is provided downstream of the perforating device in the conveying direction of the group of products for supplying the group of products with product sections.

[0039] According to an advantageous aspect, provision is made in the apparatus that an adjusting device, in particular a (preferably central) machine control unit, is provided, wherein in particular the acquired actual suction resistance of the corresponding product group is transmitted to the adjusting device, and after the actual suction resistance of the corresponding product group is transmitted, the corresponding actual suction resistance is compared or can be compared with a predetermined (preferably common to these product groups) target value for the suction resistance of the product group by the adjusting device, and when the corresponding actual suction resistance of each product group deviates from (in particular is lower than) the target value in a manner that is lower than or higher than a predetermined deviation limit value, the adjusting device transmits or can transmit corresponding control instructions to the perforation device to form separate perforation patterns, in particular perforation correction patterns, in the corresponding product groups.

[0040] Preferably, the device is designed for at least two (preferably parallel) rows of product groups, which are arranged and assembled side by side and spaced apart from each other in the longitudinal axis, wherein in the transverse axial direction, the two rows of product groups are conveyed side by side to a pneumatic inspection device and to a perforation device respectively, preferably by a roller arrangement structure with multiple conveying rollers.

[0048] In the figures, identical or similar elements and / or parts are respectively provided with the same reference numerals in order not to have to be introduced again each time.

[0049] Within the scope of the present invention, features indicated as "particularly" or "preferred" are to be understood as optional features. DETAILED DESCRIPTION

[0050] Figure 1 Schematically shown is a view of a machine 10 according to the invention for producing rod-shaped products for the tobacco processing industry. The machine 10 has two supply modules 61, 62 for supplying rod-shaped product segments to form product groups.

[0051] In a first supply module 61 , rod-shaped product rods of multiple lengths are removed from a magazine or a storage (not shown here) by means of a removal drum 12 .

[0052] In the first supply module 61, the multiple lengths of product rods arranged in the grooves on the removal drum 12 and transported in the transverse axial direction are cut into product rod segments using a cutting blade 113 and transferred to the step drum (Staffeltrommel) 13. The cut product rod segments are arranged in echelons on the step drum 13. The echeloned product rod segments are transferred to the sliding drum 16 and are moved in the longitudinal axial direction here so that they are arranged in a row in the transverse axial direction. Then, these product rod segments arranged in a row in the longitudinal axial direction are output to the cutting drum 15, where the cutting blade 113 is arranged, so as to cut the product rod segments in particular in the center. The cut filter rod segments are then transferred to another cutting drum 16, where the product rod segments of preferably double or double length are cut in the center by the cutting blade 113. Product segments for the product group to be formed are thus generated from the product rod segments, wherein the product segments are arranged in the longitudinal axial direction, for example, in the grooves of the cutting drum 16. The product segments are transferred from the cutting drum 16 to another conveying drum 17, where another cutting blade 113 can be optionally arranged to cut the product segments again. The cutting blade 113 can also be optionally arranged at the drum 16. The product segments from the providing module 61 are then transferred from the conveying drum 17 to the spreading drum 18, where the product segments are transferred and spaced or spread apart from each other in the longitudinal direction on the spreading drum 18.

[0053] The respective longitudinally axially spaced product segments for the product group to be formed are transferred from the spreading drum 18 to the assembly drum 27, wherein the product segments, in particular double or multiple lengths, are respectively inserted between the product segments provided by the first provision module 61 by the second provision module 62. In the illustrated product group, this process is schematically shown below the assembly drum 27.

[0054] In the second supply module 62, multiple-length product rods are taken out of a silo or storage (not shown here) by means of the take-out roller 22 and cut into product rod segments by means of the cutting blade 113 arranged at the take-out roller 22, so as to be transferred to the step roller 23 and arranged there in a ladder. The product rod segments are then transferred to the slide roller 24, where they are pushed into corresponding pre-set grooves in an aligned manner in the transverse axial direction. The product rod segments arranged in an aligned manner in the transverse axial direction are then transferred to the cutting roller 25, so that the product rod segments, in particular multiple-length or double-length, are cut into product rod segments by means of the cutting blade 113 arranged at the cutting roller 24. The product rod segments from the second supply module 62 are then transferred to the assembly roller 27 by means of the conveying roller 26, so that a product group with product segments from the two supply modules 61, 62 is formed or formed on the assembly roller 27.

[0055] In this way, an assembly of product groups consisting of product segments of two providing modules 61, 62 is formed in the longitudinal axial direction. The product groups with product segments are pushed together and then transferred to the conveying roller 53 so that the wrapping tape cut from the wrapping paper tape (Belagpapierstreifen) 50 is applied to the corresponding product group and the wrapping tape is wound around the product group. For this purpose, a wrapping roller 52 and a blade roller 51 used in conjunction with the wrapping roller 52 are provided at the conveying roller so that the wrapping tape of the final length is cut from the wrapping paper tape 50 and the wrapping tape is applied to the product group by the wrapping roller 52. The product group is then transferred to the subsequent rolling roller 54, where a rolling hand 55 is arranged so that the applied wrapping tape is wound around the product group.

[0056] The rolled or wrapped product group is transported from the rolling drum 54 to the cutting drum 58 via other conveying drums 56, 57 so that the wrapped product group is cut in the middle by the cutting blade 113. The cut product group is then transferred to the spreading drum 59 so that the individual and cut product groups are spaced or spread out from each other in the longitudinal axial direction in each receiving groove.

[0057] The pairs of product groups spaced apart from each other in the longitudinal direction are then transferred by the spreading roller 59 to the conveying roller 71 and then to the inspection roller 72. At the inspection roller 72, a pneumatic inspection device 80 is arranged for each row of paired product groups conveyed side by side in order to pneumatically detect or acquire the suction resistance of each product group. It is provided within the scope of the invention that a pneumatic inspection device 80 is provided for each row of product groups arranged successively in the transverse direction (with a plurality of, in particular, wrapped product sections) in order to acquire the individual suction resistance of each product group.

[0058] The actual suction resistance of each product group is transmitted by the pneumatic testing device 80 to the machine control 100. The machine control 100 has a computer, by which an actual-target value comparison is performed between the actual suction resistance of each product group and a predetermined target value for the respective product group.

[0059] The pneumatically inspected product group (as an intermediate product) is then transferred from the inspection drum 72 to the immediately following conveying drum 73 and the assembly drum 47 arranged downstream thereof.

[0060] A third supply module 64 is arranged at the assembly drum 47 , with the aid of which a further product section is added to each of the pneumatically checked product groups by means of the third supply module 64 .

[0061] In the third supply module 64, a product rod of multiple lengths is taken out from a silo or storage (not shown here) by a take-out drum 42, and then is transversely and axially transported to a cutting drum 45 by a plurality of transport drums 43, 44, where a cutting blade 113 is arranged to cut the product rod into product segments. The product segments provided by the third supply module 64 are then transported from the cutting drum 45 via a spreading drum 46 to an assembling drum 47, where the product segments of the third supply module 64 are applied to the outside of the product segments on the assembling drum 47.

[0062] Then, the added product group (as the final product) is transferred from the assembly roller 47 to the conveying roller 93 so that the wrapping tape cut from the covering paper tape 90 can be attached to the corresponding product group formed as the finished product and the wrapping tape can be wrapped around the product group.

[0063] A wrapping roller 92 and a blade roller 91 used in conjunction with the wrapping roller 92 are provided at the conveying roller 93, which are respectively used for the assembled product group on a track (Bahn) so as to cut the final length of the wrapping tape for the assembled product group from the wrapping paper tape 90, and stick the wrapping tape to the product group through the wrapping roller 92.

[0064] Subsequently, the product group provided with the attached wrapping tape is transferred to the next rolling roller 94, where a rolling hand 95 is arranged to wrap the attached wrapping tape around the product group. In the conveying area of ​​the assembly roller 47 and the conveying roller arranged downstream, the product group is conveyed in a double track or two rows spaced apart from each other.

[0065] The rolled or wrapped product group is transported from the rolling drum 94 via further transport rollers 96, 97 to the transport roller 75, where the transport rollers 76, 77 are arranged along the transport direction of the product group. The product group is transferred from the transport roller 75 to the transport rollers 76, 77 and transported back again. During the transport of the product group on the transport rollers 76, 77, a separate perforation pattern, in particular a perforation correction pattern, is provided for the product group at the corresponding position on the wrapping belt using the laser devices 86, 87 arranged thereon.

[0066] By means of a comparison of the corresponding individual actual suction resistance of the product group with a (especially predetermined) target value - suction resistance, performed by the machine control mechanism 100, a separate perforation pattern, especially a perforation correction pattern, is obtained for the corresponding each product group, so that a product group having a constant or almost constant air permeability (especially within a predetermined tolerance range) is provided at the multi-stage product manufacturing machine 10 by perforating using a separate perforation pattern to be introduced into the wrapping of the product group.

[0067] The group of products provided with the individual perforation patterns is then transferred from the conveyor roller 75 to subsequent conveyor rollers 78 , 79 .

[0068] exist Figure 2 Schematically shows another embodiment of the present invention for a multi-segment product manufacturing machine 10. The multi-segment product manufacturing machine 10 has three providing modules 61, 62, 63 for providing product groups to be processed, through which product segments for product groups to be assembled are provided respectively. The providing modules 61, 62, 63 are arranged successively in the conveying direction of the product segments or product groups.

[0069] Providing modules 61 and 62 has been directed to Figure 1 The embodiment of the present invention has been described, so please refer to the above description, which is applicable to the current embodiment in a corresponding manner. In the conveying direction of the product section, the product group assembled on the assembly roller 27 (as an intermediate product) is transferred to the next conveying roller 28.

[0070] The third supply module 63 is constructed so that multiple-length product rods are taken out from a silo or storage (not shown here) by the removal roller 32 and cut into product rod segments by the cutting blade 113 arranged at the removal roller 32, so as to be transferred to the step roller 33 and arranged there in a ladder. Then, the product rod segments are transferred to the sliding roller 34 and pushed into the corresponding pre-set grooves there in a transverse axial alignment. Then, the product rod segments arranged in a transverse axial alignment are transferred to the cutting roller 35 so that the product rod segments, in particular multiple-length or double-length, are cut into product segments by the cutting blade 113 arranged at the cutting roller 34. Then, the product rod segments from the third supply module 63 are transferred to the assembly roller 37 by the conveying roller 36, so that a product group with product segments from the three supply modules 61, 62, 63 is formed or formed on the assembly roller 37.
