Description

Arrangement of the tobacco processing industry, use of the arrangement and rod-shaped articles Description The invention relates to an arrangement for the tobacco processing industry, comprising a distribution unit and a downstream strand forming unit. The distribution unit has a suction strand conveyor guided along a suction channel and is designed to collect small parts made of an aerosol-forming material from the tobacco processing industry on a support side of the suction strand conveyor and to form a material stream from the aerosol-forming material. The strand forming unit has a format belt guided along a format channel from a format inlet area and is designed to form a strand from the material stream for the tobacco processing industry. The invention further relates to the use of such an arrangement and to a rod-shaped article for the tobacco processing industry. A machine in the tobacco processing industry with a distribution unit and a downstream strand forming device, which further comprises and provides a feed device for feeding an endless heating strip into the material sprayed onto the suction line conveyor designed as a suction belt, is known from the non-prepublished German patent application with the official file number DE 10 2023 111 233.3. Such a machine in the tobacco processing industry is used, for example, to produce rod-shaped segments used in articles of the tobacco processing industry, such as in the manufacture of so-called heat-not-burn (HNB) products. The heating strip embedded in such segments can be inductively heated by a smoking device, with the heating strip transferring its heat to the surrounding material. If the heating strip is arranged in an aerosol-forming material in the tobacco processing industry, the aroma substances present in the material can be transferred into an air stream and delivered to the consumer without any combustion process taking place. The segment produced by the aforementioned machine is, for example, a tobacco rod. The heating strip extends within the rod, for example, centrally and along the entire length of the tobacco rod. The aerosol-forming material can be tobacco-containing material provided with aerosol-forming substances, for example, reconstituted tobacco material (RECON). However, other aerosol-forming materials can also be provided, particularly those that do not contain tobacco. The term "tobacco rod" is therefore not limited to the use of tobacco material. The heating of the heating strip is controlled so that the surrounding aerosol-forming material releases the aerosol while keeping the temperature of the material below the ignition temperature. To ensure efficient heat transfer into the aerosol-forming material, A heating strip often consists of a strip-shaped, flat material that is wide in a first direction and narrow in a second direction perpendicular to it. Such a heating strip therefore has two opposing large flat sides and two opposing small flat sides, with the small flat sides located at the side edges of the strip. The aforementioned tobacco rod is assembled with additional rod-shaped segments, such as filter segments, cooling sections, flavor-influencing segments, etc., to produce a ready-to-use HnB product. The segments are then secured, for example, with a wrapping strip. EP 3 297 459 B1 discloses a device for gathering a flat sheet of aerosol-forming tobacco-containing material together with a heating strip to form a strand, the heating strip being positioned in the strand such that it is always a significant distance from the edge of the strand. The device is not designed for processing small parts made of aerosol-forming material. The device disclosed in EP 3 297 459 B1 may result in the heating strip not being positioned in the desired location, resulting in significant deviations between the actual and target positions. Furthermore, the device disclosed in EP 3 297 459 B1 does not permit any modification or adjustment of the mass or weight of the aerosol-forming tobacco-containing material.Since the rod is produced from a gathered flat sheet, the flat sheet determines the mass and weight of the aerosol-forming tobacco-containing material in the produced rod. Fluctuations in the mass or weight of the flat sheet therefore directly lead to corresponding fluctuations in the mass and weight of the tobacco rod produced from this flat sheet. Given the limits to be observed and the taste quality expected by the consumer, this effect can be undesirable. In the case of the flat sheet disclosed in EP 3 297 459 B1, Furthermore, with this device, larger gaps or voids, which have a thermally insulating effect, may arise between the gathered sections of the flat web and the heating strip, and the aerosol-forming material may only partially adhere to the heating strip, which impedes heat transfer from the heating strip to the aerosol-forming material and reduces the flavor yield. In the device known from EP 3 297 459 B1, the heating strip may be deformed when the flat web is gathered, and at least partially acquire a deformed structure and positioning in the produced strand that is unfavorable for inductive heating. The device known from EP 3 297 459 B1 makes it possible to place the heating strip, which is difficult to handle due to its fragile structure and unstable mechanical properties, into a rod. Furthermore, the device allows for a high-quality cut of the rod and the heating strip inserted into it into the tobacco rods, as the gathered sections of the flat sheet provide the heating strip with secure support and a sufficiently good abutment. Any evasive movements of the heating strip during cutting through "metal," the typical material of the heating strip, which is more difficult than with other rod materials in the form of aerosol-forming material, can be reliably avoided. DE 20 15 387 02 discloses a method for producing cigarettes consisting of an outer, rolled-up ring layer and a core rod. The ring layer consists of tobacco, while the core rod is made of a different tobacco material. A similar method is known from GB 2 260 887 A. A method for producing a tobacco rod is described in which a continuous or discontinuous core material is embedded in a rod. It is an object of the invention to provide an arrangement for processing tobacco industry, to specify a use of this arrangement as well as a rod-shaped article of the tobacco processing industry, whereby a qualitative improvement of the rod of the tobacco processing industry that can be produced by means of the arrangement is to be achieved with little design effort. The object is achieved by an arrangement of the tobacco processing industry, comprising a distribution unit and a strand forming unit arranged downstream, wherein the distribution unit has a suction strand conveying unit with a suction strand conveyor guided along a suction channel and is designed to stir up small parts from an aerosol-forming material of the tobacco processing industry on a support side of the suction strand conveyor and to form a material flow from the aerosol-forming material, and wherein the strand forming unit has a format belt guided along a format channel starting from a format inlet area and is designed to form a strand of the tobacco processing industry from the material flow. Such an arrangement is further developed by a feed device that is designed and arranged to feed an inductively heatable endless heating strip to the material flow partially or completely formed on the support side of the suction strand conveyor, optionally in the region of the distribution unit, or to the partially preformed material flow in the region of the strand forming unit. The distribution unit and the strand forming unit are arranged such that the material flow formed on the support side of the suction strand conveyor can be transferred from the suction strand conveyor into the format inlet area in a transfer area, and in the transfer area, viewed in the material flow direction of the material flow, the suction strand conveyor overlaps the format inlet area. In the transfer area between the suction line conveyor and the forming In the inlet area, viewed in the direction of material flow, there is an overlap between the distribution unit and the strand forming unit arranged downstream. In the format inlet area, the format belt circulating in the strand forming unit is deflected. The format inlet area is essentially flat or slightly concave with a very large radius. In a lower area, in which the format belt is also guided practically flat, the format inlet area merges into the lower format. In an opposite upper area, the format inlet area merges into the upper format. In the format channel formed by the upper format and lower format, the format belt is brought into a shape that is at least approximately circular in cross-section, wherein the longitudinal edges of the format belt are curved upwards in a U-shape and in particular can at least approximately abut one another and the material flow enclosed by the format belt is formed into a strand.To ensure that the strand formed in this way retains its shape, the material stream is typically deposited on a wrapping material strip, which passes through the format together with the material stream and is fixed at its long edges, for example by gluing. Due to the aforementioned overlap between the suction strand conveyor and the format inlet area, the material flow on the suction strand conveyor can be reliably transferred to the strand forming unit for strand formation. This improves the achievable quality during strand formation. According to a further embodiment, it is provided that a transport direction of the material flow on the suction strand conveyor forms an angle with a further transport direction of the strand in the format unit. The two directions are therefore in particular not coaxial. The angle is in particular in the range between 1° and 10°, furthermore in particular between 2° and 8°, furthermore in particular between 3° and 6°, furthermore in particular the angle is at least approximately 4°. The angle is measured in particular in a plane that is oriented at least approximately perpendicular to a surface, in particular a support side, of the suction line conveyor. Due to the described orientation between the suction line conveyor and the formatting belt, the material flow on the suction line conveyor is transferred to the formatting belt with a slight velocity component directed toward the formatting belt. This creates a certain momentum directed toward the formatting belt (due to the existing angular position), ensuring a particularly reliable transfer. The more reliable the transfer from the suction line conveyor to the formatting belt is, the higher the quality of the strand produced with this arrangement. According to an advantageous embodiment, the arrangement, in particular the generic arrangement, is further developed in that the distribution unit has a first drive which drives at least the suction strand conveyor (or by which at least the suction strand conveyor can be driven), and the strand forming unit has a second drive which drives at least the format belt (or by which at least the format belt can be driven), wherein the first and the second drive are designed as individual drives and in particular are not connected to one another by a torque-transmitting mechanical coupling. According to an advantageous development, it is further provided that the strand forming unit has a wrapping material feed unit that is drivable or driven by a third drive, which is arranged and configured to feed a wrapping material strip. The wrapping material strip is arranged, for example, inserted or fed, between the format belt and the material flow by the wrapping material feed unit. The third drive is designed as a single drive and, in particular, is not driven by a torque- transmitting mechanical coupling connected to the first and / or the second drive. Furthermore, the arrangement comprises, in particular, a control device with which the first and second drives, and thus a conveying speed of the suction strand conveyor and a further conveying speed of the format belt, can be coordinated with one another. In particular, such an adjustment can take place dynamically, for example during the production process. In this way, the quality of the produced strand can be optimized and modified, for example, based on data from a downstream quality inspection or measurement. Such an arrangement is more flexible than an arrangement in which the drives are mechanically rigidly coupled and allows a strand of consistently high quality to be produced even when the quality of the material to be processed varies. Similar advantages also arise with regard to the wrapping material feed unit and its third drive. For example, the aforementioned control device can further be configured to control and / or regulate not only the first and second drives but also, for example, the first, second and third drives or even the third drive in relation to the first or second drive. In this way, the conveying speed of the suction strand conveyor and the format belt and the feed speed of the wrapping material strip can be coordinated with one another. Such an adjustment can also be made dynamically, for example during the production process, and with regard to the quality of the strand produced in this way, for example as a function of values ​​determined in a downstream quality inspection. According to a further embodiment, a torque-transmitting mechanical coupling is provided between the distribution unit and the strand forming unit, in particular in the form of a common drive and / or gear unit, by means of which at least the suction strand conveyor and the format belt can be driven. The same applies to the wrapping material feed unit, which can also be mechanically coupled to the distribution unit and the strand forming unit via a common drive and / or gear unit to transmit torque. According to a further advantageous embodiment, the arrangement, in particular the generic arrangement, is further developed in that the suction line conveyor has a running side opposite the support side, is guided with its running side around an inlet roller and an outlet roller, and in particular is guided with its support side on a deflection element. According to such an embodiment, the suction line conveyor can be guided reliably and securely. In particular, the deflection element can be designed as an adjustable deflection element. With the aid of such an adjustable deflection element, for example, any longitudinal expansion of the suction line conveyor that may occur during the production process can be compensated for, or a desired pretension of the suction line conveyor can be set. The aerosol-forming material, such as bevels, accumulates on the carrying side and is transported by the suction line conveyor. The running side is opposite the carrying side and runs over the inlet and outlet rollers. Depending on the guidance of the suction line conveyor, such as a suction belt, the carrying side can also run on or around a deflection roller, for example, in the case of multiple deflections, or even around a tension roller, which can be used to adjust the desired pretension of the suction line conveyor. According to an advantageous development of the arrangement, in particular of the generic arrangement, it is further provided that the suction line conveyor is supported by a support device provided in the suction line conveyor unit, in particular in the suction channel, which with one or more static, stationary support element(s) arranged in the suction line conveyor unit, in particular in the suction channel, and / or with one or more dynamic, rotatable support element(s) arranged in the suction line conveyor unit, in particular in the suction channel. The provided support elements ensure that the suction line conveyor is guided in the intended and desired plane despite the negative pressure present in the suction channel. They form a counter-bearing to the vacuum effect of the negative pressure, which would otherwise deform the suction line conveyor, for example the suction belt, in the direction of the vacuum source and deflect it undesirably. Static support strips and / or dynamic support rollers, possibly designed differently in certain areas, can be provided. According to a first group of embodiments, the feed device is arranged and configured to feed the inductively heatable endless heating strip to the material stream partially or completely formed on the support side of the suction strand conveyor in the region of the distribution unit. Reference will first be made to these embodiments. A second group of embodiments will then be explained, in which the heating strip is fed to the partially preformed material stream in the region of the strand forming unit. Despite the conceptual and constructive differences of the heating strip feeds, advantageous further developments and aspects can be applied, as far as technically feasible, both for the concepts explained in the context of the first group (feed in the area of ​​the distribution unit) and for the concepts explained in the context of the second group (feed in the area of ​​the strand forming unit). The heating strip is designed in particular as a band-shaped heating strip and comprises two opposing, at least approximately plane-parallel, large flat sides, which are connected by small flat sides. which extend along the side edges of the band-shaped heating strip. The heating strip is a so-called susceptor strip or susceptor band, i.e. a material that has the property of absorbing electromagnetic energy and converting it into heat. In many cases, the heating strip preferably comprises an electrically conductive metal as a susceptor, which is used to transfer the induced heat to another metal surrounding the actual susceptor, or even a non-metallic material. The heat is therefore preferably first transferred between two solid bodies and then at least partially converted into radiant heat. The material of the heating strip comprises, for example, a ferromagnetic material, or further, for example, a ferromagnetic alloy, such as ferromagnetic iron, ferromagnetic steel, or even stainless steel. Other suitable susceptor materials can, for example, be made of aluminum or an aluminum alloy. The susceptor material can be selected so that it can be heated to temperatures exceeding 250 °C. The susceptor material can also be constructed from a non-metallic core with a metallic cladding. For example, metallic sections can be formed on the surface of a ceramic core. Furthermore, the susceptor material can be provided with a protective layer, for example made of ceramic or glass, which surrounds the susceptor and protects it, for example, from corrosion. It can further be provided that the susceptor material is made of two different materials, the first material being selected with regard to the desired heat loss and the associated Efficiency of heat conversion is optimized. This material can be, for example, aluminum or a ferritic material such as stainless steel. The second material can be selected so that it has a Curie temperature that is matched to a desired maximum heating temperature. When the Curie temperature is reached, the second material changes its properties from ferromagnetic to paramagnetic, which is accompanied by a change in the electromagnetic resistance. The Curie temperature is selected, for example, so that it is below the ignition temperature of the aerosol-forming material so that its combustion can be avoided with a very high degree of probability. Suitable materials for this second susceptor material are, for example, nickel or nickel alloys. The geometric profile of the heating strip is generally freely selectable. However, heating strips with a constant cross-section are generally used, whereby this cross-section can be, for example, oval, elliptical, round, square, rectangular, triangular, or polygonal. In many cases, strip-shaped heating strips with a rectangular cross-section are used, for example a metal strip. A strip-shaped heating strip has two opposing large flat sides and two connecting small flat sides, which are also arranged opposite one another. For example, the strip-shaped heating strip has a width measured transversely to its longitudinal direction and along the large flat sides, which is between 3 mm and 7 mm, preferably between 4 mm and 6 mm.The thickness or material strength of the heating strip, which is also measured transversely to its longitudinal direction but along the small flat sides (i.e., at least approximately perpendicular to the large flat sides), is, for example, between 20 pm and 130 pm, preferably between 30 pm and 100 pm, for example, 50 pm. The heating strip is processed as a continuous material in the machine of the tobacco processing industry. The heating strip is provided, for example, on a reel, which on a reel unwinder. The heating strip is guided from the reel to the feed device using corresponding, well-known deflection rollers, such as those used for web guidance in the tobacco processing industry. The heating strip can be fed horizontally or vertically in both the distribution unit and the strand forming unit. A horizontal orientation of the heating strip is also referred to as a 90° orientation. In this configuration, the large flat sides of the belt-shaped heating strip extend at least approximately parallel to a support side of the suction strand conveyor or to an upper side of the format belt facing the material flow in the format inlet area, i.e. at the start of the format channel. The material flow does not lie directly on the format belt. A strip of wrapping material, for example a paper web, is located between the format belt and the material flow. The strand formed in the strand forming unit is enclosed by the strip of wrapping material and thus stabilized.In a vertical orientation, which should also be referred to as 0° orientation, the large flat sides of the band-shaped heating strip extend at least approximately perpendicular to a support side of the suction strand conveyor or to a surface of the format belt, wherein due to the deformation of the format belt that typically occurs in the format channel, reference is made to the start of the format channel in the format inlet area, at which the material flow is transferred from the distribution unit to the strand forming unit, before the strand forming then takes place in the format channel under a curvature or a closing of the format belt. Furthermore, orientations of the heating strip other than 0° or 90° are possible, in particular an orientation in the range between 20° and 70°. The suction line conveyor is, in particular, a suction belt. The suction belt It can be constructed as a woven fabric with warp and weft threads or as a conveyor belt with endless, transversely arranged webs that are spaced apart from one another via closed tension elements (e.g., wire ropes) and firmly connected to one another. The latter design will be discussed in more detail below. In the following, embodiments of the first group are explained, according to which the arrangement is further developed in that the supply device is arranged and configured to supply the heating strip to the material flow in the region of the distribution unit. In particular, it is provided that the supply device is arranged and configured to supply the heating strip to the material flow in the region of the suction line conveyor of the distribution unit. Feeding the heating strip in the area of ​​the distribution unit advantageously allows for flexible arrangement of the heating strip in the material flow. If, for example, the heating strip is fed into the material flow in the area of ​​the suction line conveyor, the position of the heating strip in the material line can be specifically influenced by appropriate positioning of the feed device. If, for example, the heating strip is fed into the material flow closer to the beginning of the suction line conveyor, comparatively little material will have showered on the suction line conveyor. If the heating strip is oriented at 0°, it can be inserted into the showered material relatively easily. If the feed device is arranged at a position at which approximately half of the material has already showered on the suction line conveyor, the heating strip can be positioned relatively precisely in the center of the material flow with a 90° orientation, for example.The embedding of the heating strip in the aerosol-forming material can also be optimized with regard to the desired thermal contact between the heating strip and the aerosol-forming material. This affects not only the positioning of the heating strip in the material flow but also the mass of the material flow. This, in turn, will affect the material density of the strand produced from the material stream. In addition to quality aspects, the material density also influences the thermal coupling between the heating strip and the aerosol-forming material, which is also a quality characteristic. According to a further embodiment, the arrangement is further developed in that a partition wall is arranged in the suction channel of the distributor unit, which partition wall extends in the material flow direction and divides the suction channel at least in sections into a first and a second partial suction channel and is arranged at least approximately centrally in the suction channel transversely to the material flow direction, wherein the distributor unit further has or can have a nozzle trough for supplying the aerosol-forming material to the suction channel, wherein the nozzle trough is divided into a first partial nozzle trough and a second partial nozzle trough and the first partial nozzle trough is arranged and designed to supply aerosol-forming material to the first partial suction channel and the second partial nozzle trough is arranged and designed to supply aerosol-forming material to the second partial suction channel. The aforementioned embodiment is advantageous for a 0° orientation of the heating strip. The partition wall arranged in the suction channel is furthermore designed, in particular, as part of the feed device. For example, the partition wall comprises a guide slot or a guide channel in which the heating strip can be guided. With the aid of the divided nozzle recess, which is or can be constructed from the first and second partial nozzle recesses, aerosol-forming material can be sprayed onto both sides of the partition wall. Only when the desired height of the material flow is reached, i.e., a sufficient amount of aerosol-forming material has been sprayed, is the heating strip transferred from the partition wall into the material flow. This results in precise and reliable embedding of the heating strip in the material flow at a 0° orientation. According to a further embodiment, this arrangement is further developed in that the first partial nozzle trough and the second partial nozzle trough extend in the material flow direction in different regions of the suction channel and in particular do not overlap. For example, the second nozzle recess portion can be closed with a suitable cover plate in the area where the first nozzle recess portion extends, so that only material is introduced into the first nozzle recess portion. The same applies analogously to the area where the second nozzle recess portion extends. Here, the first nozzle recess portion can be closed with a suitable cover plate. Furthermore, it is particularly provided that the aforementioned cover plates are designed as a control device for controlling a material flow supplied to the first and / or second partial nozzle recess. For this purpose, the cover plates are designed, for example, to be adjustable. The cover plates, together with the control device, can form a mass flow supply control device. According to a further embodiment, the arrangement is further developed by a mass measuring device which is arranged and configured to measure a mass of the material flow in the first and / or second partial suction channel, wherein a mass flow supply control device is furthermore comprised which is arranged and configured to control a first mass flow to the first partial suction channel and / or a second mass flow to the second partial suction channel and wherein, furthermore, in particular the mass measuring device is configured to control or regulate the mass flow supply control device based on a measured value for the mass of the material flow in the first and / or second partial suction channel. With the aid of the mass flow supply control device, the mass flow can be controlled or regulated in such a way that in the first and second An equal mass of aerosol-forming material is sprayed into the partial suction channel. Furthermore, according to further embodiments, the mass flow supply control device can be controlled or regulated in such a way that a predeterminable first partial mass is present in the first partial suction channel and a predeterminable second partial mass is present in the second partial suction channel. By means of the corresponding mass measuring device, in particular, a feedback control and / or regulation of the mass flows can be carried out with the aid of the mass flow supply control device. The mass measuring device is configured to measure the mass flow in at least one of the partial suction channels, in particular in both partial suction channels. The mass measuring device is, for example, a microwave measuring device. The microwave transmitter can be integrated into one of the channel cheeks of the suction channel. A microwave receiver can be arranged in the partition wall. With this configuration, the mass of the mass flow flowing between this channel cheek and the partition wall can be measured. In another embodiment, a microwave transmitter / receiver can be integrated into the channel cheek of the suction channel, with a suitable reflector integrated into the partition wall. With such a measuring configuration, the integration of a receiver in the partition wall can advantageously be dispensed with, which simplifies the design.For all these embodiments, the channel cheeks and / or the partition wall, at least in the area of ​​the mass measuring device, can be made of non-metallic, in particular ceramic materials or can be coated with non-metallic, in particular ceramic materials. According to a further advantageous embodiment, the arrangement is further developed by a suction air throttle, which is arranged and configured to at least partially control or regulate a suction air flow applied to the suction line conveyor in the suction channel. Furthermore, it is particularly provided that the suction air throttle is activated once. is set so that the desired suction air flow distribution is achieved in the suction duct. The presetting can be maintained, i.e., remain constant, for the desired production duration. With the help of the suction air throttle, which is implemented, for example, using appropriate cover plates, the suction effect of the suction line conveyor, for example the suction belt, can be changed along the suction channel. By sectionally adjusting or shaping, controlling and / or regulating the suction air flow applied to the suction line conveyor and at least partially passing through the suction belt, for example, the suction effect can be reduced, for example at the beginning of the suction line conveyor, where comparatively little material has showered onto the support side of the suction line conveyor. The cover plate present in this area can be adjusted so that the suction channel is relatively largely closed. As the height of the showered material increases, the flow resistance through the showered material increases.It may therefore be desirable to increase the suction air flow applied to the suction line conveyor in a further downstream area of ​​the suction channel by opening the suction air throttle with a comparatively larger opening. The cover plate present in this further downstream area can be adjusted so that the suction channel is opened wider, which is the case upstream. By adjusting the cover plates accordingly, for example, a constant suction effect can be achieved along the entire length of the suction channel – also taking into account the increasing flow resistance with increasing amount of material being blown up. Furthermore, it is possible, for example, to adapt the suction effect of the suction line conveyor to the material being processed using the suction air throttle. According to a further advantageous embodiment, the arrangement is further developed by a trimming device which is arranged and adapted to is configured to trim the material flow in a plane that is arranged obliquely to the support side of the suction line conveyor. In particular, the trimming plane forms an angle with the support side of the suction line conveyor that is at least approximately 45°. According to a further embodiment, the trimming device can also be arranged such that it trims the material flow in a plane that is arranged at least approximately parallel to the support side of the suction line conveyor, or in particular horizontally. According to an alternative embodiment, the arrangement is further developed in that the suction channel including the suction line conveyor, viewed in a plane transverse, in particular perpendicular, to the material flow direction, is arranged obliquely with respect to the format belt guided in the format channel, so that in particular a support side of the suction line conveyor forms an angle of at least approximately 45° with a surface of the format belt facing the material flow in the format inlet area. With the aid of the aforementioned embodiments, a 45° orientation of the heating strip can be advantageously realized. The previously mentioned different orientations of the heating strip not only affect the process of embedding the heating strip in the material flow. The orientation of the heating strip in the material flow corresponds, except for process-related inaccuracies, to the subsequent orientation of the heating strip in the strand. Since it is necessary to cut the continuously produced strand into rod-shaped segments of a desired length, the strand must be cut using a cutting device. The cut, which is carried out using a knife apparatus of this cutting device, is carried out with varying quality and with varying degrees of wear on the blade depending on the orientation of the heating strip. In order to achieve a corresponding optimization of the orientation of the band-shaped heating strip with regard to the cutting To be able to adjust the heating strip to the device, more precisely to the cutting blade of the knife assembly, it is advantageous to be able to position the heating strip in the strand with a flexible orientation. A 45° orientation has proven to be an interesting alternative to the 0° and 90° orientations in this context. The knife device has a center of rotation around which a cutting blade of the knife device rotates. The above-mentioned orientations of the heating strip are preferably carried out depending on the positioning of the knife device relative to the strand such that a cut is made perpendicularly through the heating strip. The orientation between the strand and the knife device is in particular as follows. The heating strip is a ribbon-shaped heating strip with two large, opposite flat sides. These flat sides preferably lie in a plane defined by a line running along the center of the strand, which essentially corresponds to the material flow direction of the strand, and a connecting line between the center of rotation of the knife device and the center of the strand.Furthermore, in particular, an orientation of the heating strip is provided in which the large flat sides of the heating strip deviate from this plane by +- 45°, in particular by +- 15°, further in particular by +- 5°. According to a further advantageous embodiment, the arrangement is further developed in that the suction channel is delimited by two channel cheeks extending in the material flow direction, the inner sides of which, together with the suction line conveyor, form the suction channel, wherein the feed device is arranged and integrated into one of the two channel cheeks in such a way that the endless heating strip can be fed to the material flow through the inner side of this channel cheek. The heating strip can be fed through the channel cheeks of the suction channel in either a 0° or 90° orientation. In the 90° orientation, a twist of the heating strip is also advantageous, as it is in a plane in which its large flat sides, can only be guided around curves with very large radii. Inserting the heating strip through the channel cheeks is particularly suitable for converting or upgrading existing machines, as only minor changes to the existing configuration are required. Furthermore, there is often sufficient space available in the area of ​​the channel cheeks to feed the heating strip. According to a further advantageous embodiment, the arrangement is further developed in that the suction line conveyor has a clamping device on its support side, which is arranged and configured to hold the heating strip in a clamping grip. This embodiment concerns a 0° orientation of the heating strip. In the □" orientation, there is always the risk that the heating strip will lose the desired orientation in the suction channel, for example, if it is affected by the material being blown up and tipping over toward the 90° orientation. Using the clamping device on the support side of the suction strand conveyor, the heating strip can be fixed in the desired □" orientation. The quality of the produced strand can be improved in this way. According to an advantageous further development, such an arrangement is characterized in that the heating strip has large flat sides opposite one another and the clamping device has a cooperating pair of clamping jaws which are designed to hold the heating strip in the clamping grip on its large flat sides. Furthermore, it is particularly provided that the arrangement is developed in such a way that the suction line conveyor has a plurality of web-shaped segments arranged transversely one behind the other in a longitudinal direction of the suction line conveyor, which are coupled to one another in a tensile-stable manner, wherein at least some, in particular all, segments have a clamping element and the clamping elements present on the support side of the suction line conveyor form the clamping device. The tensile-stable coupling of the web-shaped segments is achieved in particular by means of cables, for example, wire ropes. The web-shaped segments can be plastic parts, in particular injection-molded plastic parts that are molded around the cables. Furthermore, the clamping device is preferably formed integrally, materially, or as a single piece with the web-shaped segments. According to a further advantageous embodiment, such an arrangement is further developed in that the pair of clamping jaws has a first clamping jaw and a second clamping jaw, the orientation of which can be reversibly changed so that the pair of clamping jaws can be reversibly placed into a closed or an open state. For this purpose, the two clamping jaws are designed, for example, to be pivotable or displaceable. In the closed state, the pair of clamping jaws exerts a clamping force on the large flat sides of the heating strip to provide the clamping grip. In the open state, the clamping jaws release the heating strip. To provide the clamping force, a suitable spring can be provided, for example, whereby the clamping jaws exert a clamping grip on the large flat sides of the heating strip similar to a clamp.The clamping force can also be provided by reversible material deformation, for example, of the clamping jaws themselves or of an elastic element connected to the clamping jaws. In other words, the clamping device can be designed as a clamping system with a return spring. Furthermore, it is particularly provided that the segments are reversibly changeable in their position relative to one another between a closed and an open state, in particular bendable, wherein the segments extend at least approximately parallel to a support side of the suction line conveyor in the closed state and in the open state In this state, the free ends of the segments located on the side edges of the suction line conveyor are bent out of a plane of the support side and away from the support side, wherein the pair of clamping jaws is arranged on an upper side of the segment forming the support side and is in particular formed integrally with the segment, and wherein the pair of clamping jaws, in the closed state, exerts a clamping force on the large flat sides of the heating strip to provide the clamping handle and, in the open state, releases the heating strip. The segments are designed in such a way that they automatically return from the open to the closed state. This return force acts, at least in part, as a clamping force on the heating strip. For this purpose, a suitable elastic material is used to manufacture the web-shaped segments. In order to bring about the transformation between the open and closed state during the ongoing process and to transfer the web-shaped segments at the beginning of the suction line conveyor into an open state so that the belt-shaped heating strip can be positioned between the open clamping jaws, it can be provided, for example, that the suction line conveyor has a running side opposite the support side (on which the clamping device is present), wherein the suction line conveyor is guided with its running side around an inlet roller. Additional guide rollers which interact with the running side of the suction line conveyor can of course be provided. At the beginning of the suction channel, the suction line conveyor is guided around the inlet roller, wherein the inlet roller can be designed as a spherical roller.As the transport distance increases in the direction of material flow, the clamping jaws of the web-shaped segments close and secure the heating strip in the clamping grip. This occurs either through the restoring force of the self-restoring web-shaped segments or through appropriate guidance of the segments. In another embodiment or in addition, it may be provided that the clamping jaws of individual, in particular non-consecutive, segments are positioned offset relative to the clamping jaws of adjacent segments transversely to the direction of material flow. This results in a clamping effect on the heating strip between the clamping jaws of consecutive segments, which are arranged opposite one another in pairs. It is further provided that the entire segment is arranged laterally offset, which simplifies the manufacture of such a suction line conveyor. To insert the heating strip into such a suction line conveyor, the laterally offset segments can be moved laterally in an insertion area of ​​the heating strip, for example with the aid of a lateral roller guide. As a result of this displacement, the clamping jaws are oriented longitudinally flush with the clamping jaws of the other web-shaped segments, so that the heating strip can be inserted. According to a further advantageous embodiment, the arrangement is further developed by at least one heating strip guide device which is arranged and configured to guide the heating strip downstream of the supply device, wherein the heating strip guide device is arranged in particular in the region of the distributor unit, furthermore in particular in the suction channel. The heating strip guide device can be configured to guide the heating strip in a 0° orientation or to guide the heating strip in a 90° orientation. A single guide element can form the heating strip guide device, or two or more guide elements can jointly form the heating strip guide device. One guide element or several guide elements can be accommodated, in particular with a fastening end, in a channel cheek. One guide element or several guide elements can be arranged with a free guide end extending from a channel cheek into the suction channel. One guide element or several guide elements can be designed and positioned to extend from a channel cheek into the suction channel over a length of more than 0.8 mm, preferably more than 1 mm and / or less than 3 mm, preferably less than 2.7 mm, up to their free guide end or their guide groove. A plurality of guide elements can be provided, in particular arranged in a first channel cheek and in a second channel cheek, which is opposite the first channel cheek, such that the guide elements of the first channel cheek and the second channel cheek are opposite one another or are offset from one another in the direction of the longitudinal extent of the suction line conveyor. In particular, the heating strip guide device has at least one guide element, in particular two opposing guide elements, which interact with the side edge or the side edges of the band-shaped heating strip. The heating strip guide elements each have, for example, a groove in which the heating strip can be guided or is guided. In the region of the heating strip guide elements, the heating strip dips into the associated groove of the guide element with one of the two side edges, or with both side edges if pairs of opposing heating strip guide elements are provided. The at least one heating strip guide element is arranged in particular in the suction channel. For example, the heating strip guide element is embedded in a lateral cheek of the suction channel or fastened to it.Furthermore, it is particularly provided that the at least one heating strip guide element is designed to be aerodynamically favorable in the direction of material flow. For example, it is rounded or flattened, resulting in low flow resistance or frictional resistance for the material flow at the guide element. Furthermore, the heating strip guide element is designed, for example, as a disc, wherein the disc comprises a circumferential groove along its circumference, in which a side edge of the heating strip can be guided. For example, the heating strip is fixed to the its side edges. The disks rotate passively or actively driven at a speed corresponding to the conveying speed of the heating strip in the material flow. The axis of rotation of the disk extends in particular perpendicular to the large flat side of the heating strip. Furthermore, the axes of rotation of the disks designed as heating strip guide elements can be aligned at least approximately perpendicular to a support side of the suction line conveyor. The rotational speed is selected, for example, such that the relative speed between the heating strip and the groove base in the disks is as low as possible. The aforementioned heating strip guide devices relate in particular to guiding the heating strip in a 90° orientation. In a 0° orientation, for example, one side edge of the heating strip rests on the suction line conveyor and moves with it. The opposite side edge can be guided in a groove of a heating strip guide device. This is designed, for example, as a wheel. This wheel also rotates at a speed adapted to the transport speed of the heating strip in the material flow. In the 0° orientation, the heating strip can also be guided by rollers. These rollers can, for example, roll along the large flat sides of the heating strip, thus preventing the heating strip from tipping over in the suction channel. The rotation axis of such a roller extends, for example, in a plane parallel to the large flat sides of the heating strip or, furthermore, in a plane parallel to a support side of the suction line conveyor. If the heating strip is fed into the material flow via a feed device designed in the manner of a feed lance, the feed lance can be stabilized in the area of ​​its transfer end by means of a mechanical holder. This holder serves as a heating strip guide device in that it prevents movement, for example, a Fluttering of the transfer end of the feed lance in the suction channel is prevented. For this purpose, for example, the transfer end is supported against one or both channel cheeks. The heating strip guide device can be designed to be adjustable, both with regard to the orientation of the heating strip relative to its distance from the suction line conveyor (in particular, a distance from the support side of the suction line conveyor) and with regard to the orientation of the heating strip transverse to this direction. Furthermore, the heating strip guide device can be designed to be rotatable, so that the heating strip can also be guided with an orientation deviating from the 0° or 90° orientation, or the orientation of the heating strip can be at least slightly changed by the heating strip guide device. According to a further embodiment, the arrangement is further developed in that the feed device is arranged downstream of the suction channel and upstream of the format channel and is designed to feed the heating strip to the material flow between the suction channel and the format channel, wherein in particular a trimming device is provided which is arranged and designed to trim the completely shredded material flow downstream of the suction channel to a predetermined or predeterminable height, wherein the feed device is arranged downstream of the trimming device and upstream of the format channel and is designed to feed the heating strip to the trimmed material flow. In other words, the heating strip is inserted into the material stream intended for further processing, which has been completely spread and trimmed to the desired height. This material stream can be guided or can be guided between the suction channel and the format channel in a transport channel. The feed device, for example, is located in the area of ​​this transport channel. The feed device can have a transfer end that is designed like a plow, so that that the material flow can be divided, or is divided, particularly locally and / or temporarily, by this plow-like transfer end, or its density is changed, in particular reduced. The transfer end creates a free space or an insertion zone with at least, particularly locally and / or temporarily, reduced material flow density, into which the heating strip can be inserted. In this way, an insertion zone for the heating strip is created. This applies both to the insertion of a heating strip in a 90° orientation and to the insertion of a heating strip in a 0° orientation. In order to be able to guide the material flow in the area of ​​the transfer end without causing discontinuities, such as accumulations, empty spaces, or even blockages, which would result in a production interruption, according to a further embodiment, the arrangement is further developed by a transport channel in which the material flow can be guided between the suction channel and the format channel. The transport channel has a cross-sectional widening in the area of ​​a transfer end of the feed device, at which the heating strip can be transferred from the feed device into the material flow. This cross-sectional widening allows the material flow to avoid the transfer end of the feed device, while maintaining the continuity of the material flow. According to a further embodiment, alternatively or in addition to a cross-sectional widening, the arrangement is further developed by a transport channel in which the material flow can be guided between the suction channel and the format channel, wherein the transport channel is laterally delimited by a pair of transport channel cheeks extending in the material flow direction and at least one of the transport channel cheeks is equipped with a material flow transport aid at least in the region of a transfer end of the feed device, at which the heating strip can be transferred from the feed device into the material flow, wherein in particular the material flow transport aid is implemented by one or more of the following measures: a) the channel cheek is designed as a conveyor belt, b) the channel cheek has air transport channels, c) the channel cheek is designed to vibrate, d) a surface of the transport cheek facing the transport channel is provided with a friction-reducing coating, e) the channel cheek is designed as a screw conveyor, f) the channel cheek has liquid channels for the outlet of a friction-reducing liquid. The above-mentioned statements regarding the design of at least one channel flange also apply, in the same or mixed form, to the other channel flange located opposite. All embodiments support the transport of the material flow in the direction of the material flow and in the area of ​​the transfer end of the feed device. According to a further embodiment, the transfer end of the feed device, which is particularly designed in a plow-like manner, is also configured to support material transport in its area. For this purpose, the transfer end of the feed device is provided, for example, with air transport channels, is designed to vibrate, is provided with a friction-reducing coating, and / or is provided with fluid channels for the discharge of a friction-reducing fluid. According to a further embodiment, the arrangement is further developed by a material flow transfer device which is arranged and configured to support the material flow which can be or has been showered on the support side of the suction line conveyor in the transfer area from a side facing away from the suction line conveyor and to convey it at least approximately in the material flow direction, wherein in particular the material flow transfer device is designed as a conveyor belt and / or as a compressed air conveying unit. The material flow transfer device supports the material transport in the area of ​​transfer from the suction strand conveyor to the format inlet area. A material flow transfer device is particularly advantageous when the feed device with which the heating strip is introduced into the material flow is arranged shortly before the start of the strand forming unit, i.e. only slightly upstream of the format belt. In such a case, supporting the material transport, again in the area of ​​the transfer end, is of particular importance. In this context, it can be advantageously exploited that there is typically an angle between the material transport direction of the material flow in the distribution unit and another material transport direction of the strand in the strand forming unit. The heating strip can be fed in the area of ​​this angle or knee, for example in a direction that is aligned with the transport direction of the strand. The following describes embodiments according to the second group, in which the feed device is arranged in the region of the strand forming unit. Specifically, the arrangement is further developed in particular in that the feed device is arranged and configured to feed the inductively heatable endless heating strip to the partially preformed material stream in the region of the strand forming unit, in particular in the format inlet area or also in the region of the format channel of the strand forming unit. The supply of the heating strip in the area of ​​the strand forming unit allows for particularly precise positioning of the heating strip. Strand formation begins with the loose aerosol-forming material, continues with the formation of the material flow on the suction strand conveyor, and finally, the strand is formed in the strand forming unit and secured, for example, by a suitable wrapping such as a wrapping material strip. The further the strand formation progresses, i.e., the later the supply of the heating strip takes place in this process, the smaller the influence of the material flow forming process and the strand forming process on the orientation. of the heating strip in the subsequent strand. Therefore, supplying the heating strip in the area of ​​the strand forming unit results in particularly precise positioning of the heating strip. According to a further advantageous embodiment, the arrangement is further developed in that the feed device is arranged and configured to feed the heating strip to the partially preformed material flow in the region of the format inlet region of the strand forming unit, wherein the inlet region is designed as a divided format inlet region, through the partial sections of which a partial material flow is guided, and the feed device is designed as an insert wheel engaging in the divided format inlet region. The use of an insert wheel, whose basic design is familiar from capsule insertion, for example, has proven advantageous for inserting a heating strip into the preformed material flow in the inlet area. This particularly applies, but not exclusively, to inserting a heating strip at a 90° orientation. To prevent material jamming in the region of the transfer end of the feed device, it has proven advantageous to further develop the arrangement as follows. According to a further embodiment, the feed device is arranged and configured to feed the heating strip to the partially preformed material stream in the format inlet region or in the region of the format channel, wherein the format inlet region or the format channel has a cross-sectional widening in a transfer region and / or deflection elements that are arranged and configured to convey portions of the strand material in a direction away from the format belt. The deflector elements cause material to be transported in a direction away from the format belt. Thus, the deflector elements counteract the displacement effect that the feed device has on the material of the partially The partially preformed material flow is thus restored. The transfer end is defined as the area of ​​the feed wheel that comes into contact with the partially preformed material flow. According to a further embodiment, a guide for the heating strip is provided in the format channel. This guide device can be adjustable, whereby both the distance of the heating strip from the format belt or from a guide surface of the format inlet area can be adjusted, as can the lateral orientation of the heating strip relative thereto. The guide device can also be formed integrally with the format inlet area or format channel, so that a non-adjustable guide for the heating strip is provided, or a guide that can be adjusted together with the format inlet area, for example, an inlet finger, is formed. The following embodiments relate both to an embodiment of the arrangement according to the first group, in which the heating strip is supplied to the material flow in the region of the distribution unit, and to embodiments according to the second group, in which the heating strip is supplied to the strand in the region of the strand forming unit. The heating strip can be guided magnetically, either as a modification or in addition to the previously mentioned mechanical guides. This is advantageous because the heating strip is made of inductively heatable material and is therefore also magnetizable. According to a further embodiment, the heating strip can be stabilized by imprinting a three-dimensional shape onto it. For example, the heating strip can be deformed in a wave-like or groove-like manner in the longitudinal and / or transverse directions, thereby increasing the stiffness of the heating strip in the longitudinal direction. In one embodiment, a manipulation device A is provided in the arrangement, which is designed and configured to change the cross-sectional shape of the heating strip, in particular to provide the heating strip with elevations, steps, beads, kinks, and / or depressions along its width or its large flat side, which extend in particular along its length, in particular at least in sections or continuously, and in particular to change or leave unchanged the thickness of the heating strip, in particular along its width or its large flat side. The manipulation device A can be arranged upstream of the format unit and the suction line conveyor. According to one embodiment of the arrangement, the feed device is arranged and configured to feed the heating strip to the strand in the region of the strand forming unit, in particular in a zone in which the strand which has been showered, trimmed and transferred to the strand forming unit is not yet enclosed by a wrapping layer, in particular in the form of a wrapping material strip, for example wrapping paper, and the strand is guided in particular between a downwardly open format inlet region or inlet finger which is provided with a downwardly facing, at least partially concave guide surface, and a wrapping layer. According to further embodiments, the arrangement is further developed in that the heating strip has one or more of the following features: a) the heating strip has mechanically weakened regions at regular intervals, in particular a region of reduced width, a region of reduced material thickness, a region of partial perforation and / or a region of perforation, b) the heating strip is completely partially perforated or perforated. A further embodiment of the arrangement comprises a manipulation device B which is arranged and designed a) to provide the heating strip at regular intervals with weakened areas, in particular mechanically, in particular in the form of an area of ​​reduced width, an area of ​​reduced material thickness, an area of ​​partial perforation and / or an area of ​​perforation, in particular through-perforation, or b) to partially perforate the heating strip completely, in particular in the manner of a blind hole recess limited at the bottom, or to perforate it, in particular with a through-opening. Manipulation device B can be arranged upstream of the format unit and the suction line conveyor. The arrangement is particularly designed and configured to supply a single heating strip to the material flow. This particularly applies to the design and configuration of the supply device. The object is further achieved by the use of an arrangement according to one or more of the aforementioned embodiments for producing a rod for the tobacco processing industry for rod-shaped articles of the tobacco processing industry, in particular for heat-not-burn articles. The use of the arrangement offers the same or similar advantages as those already mentioned with regard to the arrangement itself, so repetition is omitted. Furthermore, the object is achieved by a rod-shaped article of the tobacco processing industry, in particular a heat-not-burn article, produced using a rod of the tobacco processing industry produced with an arrangement according to one or more of the aforementioned embodiments. The same or similar advantages as those already mentioned above with regard to the arrangement also apply to the rod-shaped article of the tobacco processing industry.

Within the scope of the invention, features marked with “in particular” or “preferably” are to be understood as optional features. In the drawings, identical or similar elements are shown and / or parts are provided with the same reference numbers, so that a repeated presentation is omitted in each case. Fig. 1 schematically shows a PROTOS cigarette rod making machine from Hauni Maschinenbau GmbH, exemplified as a machine 100 used in the tobacco processing industry. The machine 100 comprises an assembly 50 used in the tobacco processing industry. The arrangement 50 present in the machine 100 comprises a distribution unit 102, a downstream strand forming unit 104, and a feed device 108, which is explained in more detail using various exemplary embodiments in the figures following Fig. 1. First, however, the machine 100, as shown in Fig. 1, will be briefly explained. Starting from a lock 1, a pre-distributor 2 is fed, for example, in portions with small parts made of an aerosol-forming material used in the tobacco processing industry. For example, conventional cut tobacco, which is provided with an aerosol-forming substance such as propylene glycol and / or glycerin, can be fed in. Likewise, small parts made of reconstituted tobacco material (RECON small parts), which is also provided with aerosol-forming additives, can be fed in and processed. Before this material is fed in, it undergoes a comminution process so that, for example, RECON small parts can be fed to the tobacco processing industry as an aerosol-forming material.Furthermore, tobacco-free aerosol-forming material, for example a material made from corn, which in turn is provided with corresponding aerosol-forming substances and processed into small parts, can be processed as aerosol-forming material in the tobacco processing industry. A removal roller 3 of the pre-distributor 2 supplements a storage container 4 with the aerosol-forming material, from which with the help of a The material is removed from an inclined conveyor 5 and fed into a storage chute 6. From the storage chute 6, a pin roller 7 removes a uniform stream of small particles of the aerosol-forming material, which is then knocked out of the pins of the pin roller 7 by a knock-out roller 8 and thrown onto a spreading cloth 9 rotating at a constant speed. A web of small particles formed on the spreading cloth 9 is fed to a screening device 11, which essentially consists of an air curtain through which larger or heavier small particles pass, while all other particles are guided by the air into a funnel 14 formed by another pin roller 12 and a wall 13. Depending on the quality of the small particles fed in, the screening may also be omitted. The additional pin roller 12 feeds the material into a channel and from there, it is thrown against a suction line conveyor 17, for example, a suction belt, of a suction line conveyor unit 18. The small parts adhere to the suction line conveyor 17, which runs along a suction channel 16, due to a negative pressure generated in the suction channel 16. The small parts are sprayed onto the suction line conveyor 17 by the air drawn in via the suction channel 16, where they form a so-called cake, which is also referred to as a material flow. The feed device 108 can be arranged at various positions as part of the arrangement 50. An arrow, labeled A, indicates that a transfer end of the feed device 108 can be located at this point or in this area of ​​the machine 100, i.e. in the area of ​​the distribution unit 102, or in the area of ​​the suction line conveyor unit 18, more precisely at its suction line conveyor 17. With the feed device 108, a heating strip 110 is introduced into the material flow of small parts made of an aerosol-forming material from the tobacco processing industry, which flow is showered onto the suction line conveyor 17. In other words, the feed device 108 is designed to supply the inductively heatable endless heating strip to the Suction strand conveyor 17 to feed the material. The exact position and design of the feed device 108 can be selected flexibly and depending on the desired properties of the machine 100 or the arrangement 50, or can also be changed and adjusted with regard to the rod-shaped articles produced with such an arrangement 50 or the strand produced thereby. According to further embodiments, the feed device 108 is arranged at a position indicated by an arrow labeled B. According to such an embodiment, the feed device 108 is arranged downstream of the suction channel 16 and upstream of a format channel 25 of the strand forming device 104. In particular, it is provided that the feed device 108 is arranged downstream of a trimming device 19 and upstream of the format channel 25. Finally, according to further embodiments, the supply device 108 is arranged at a position or in a region indicated by an arrow labeled C.According to these exemplary embodiments, the feed device 108 is arranged and configured to feed the heating strip 110 to the partially pre-formed material flow 54 in the region of the strand forming unit 104, in particular in a zone in which the material flow that has been showered, trimmed and transferred to the strand forming unit 104 is not yet enclosed by a wrapping layer, in particular in the form of wrapping paper, and the material flow is guided in particular between an inlet finger that is designed to be open at the bottom and is provided with a downward-facing, at least partially concave guide surface as a format inlet region and a wrapping material layer that is received on the format belt 24, in particular in the form of a wrapping material strip 21, for example a paper strip. Examples of different arrangements of the feed Device 108 is explained in more detail in the figures following Fig. 1. First, we will continue with the explanation of machine 100 as shown in Fig. 1. The material that is showered onto the suction line conveyor 17 in the area of ​​the suction line conveyor unit 18 is trimmed to the desired height using a trimming device 19. Excess material is removed from the showered material stream so that the showered material stream of aerosol-forming small particles reaches the desired target height. The target height is measured between a support side of the suction line conveyor 17 facing the extruded material and an opposite side or surface of the extruded material flow, where the extruded material flow is trimmed to the desired target height. The support side of the suction line conveyor 17 is also referred to as the tobacco side or suction side of the suction line conveyor 17. The extruded material flow is located on this side. The sifted and trimmed material stream is placed further downstream onto a wrapping material strip 21, for example, a wrapping paper strip as the wrapping material, which is guided at a coordinated speed, and enters the downstream strand forming device 104. The wrapping material strip 21 is fed by a wrapping material feed unit (not further described), which also includes the arrangement 50. The speed of the suction strand conveyor 17 can be greater than, less than, or equal to the speed of the format belt or the wrapping material strip 21. In the strand forming unit 104, the material flow is guided from a format inlet area located in a transfer area 39, together with a format belt 24 through a format channel 25 of a format unit 26. The material passes through the format unit 26, strand forming. The wrapping material strip 21 intended for wrapping the strand produced in this way is drawn off a reel 22, guided through an optionally provided printing unit 23, and placed on the driven formatting belt 24. The formatting belt 24 transports the strand together with the wrapping material strip 21 through the formatting unit 26. In the formatting unit 26, the wrapping material strip 21 is wrapped around the strand so that an edge protrudes, which is glued in a conventional manner by a gluing device (not shown). The glued seam is then closed and dried in a seaming plate 27. The strand 28 produced in this way then passes through an optional strand density measuring device 29, which can be configured to control the trimming device 19. The strand 28 is then cut into rod-shaped segments by a knife device 31. The segments are then fed by a transfer device 34 having controlled arms 33 to a receiving drum 36, for example, a collating device 37. On the collating drum 38, the rod-shaped segments, in which the heating strip 110 is embedded, can be combined with other segments, such as filter segments or cooling sections or cooling segments, to form a rod-shaped article. This article can be fed for further processing. Furthermore, a sensor device (not shown) can be arranged in the area of ​​the transfer device 34, for example, an optical sensor that detects the end-face cut surfaces of the rod-shaped segments. With the aid of such a sensor, as is disclosed, for example, in the unpublished German patent application with the official file number DE 10 2022 124 016.9, both an absolute position and an angular position of the heating strip 110 embedded in the rod-shaped segment can be determined. Another sensor suitable for this measuring task is, for example, from DE 695 15 482 T2, and is described there in connection with Fig. 3. Such a sensor operates in a transmitted light process. Another sensor, which can be integrated into the machine 100 for the aforementioned purposes, is known from EP 3 497 438 B1, in particular paragraph

[0032] , known. This sensor operates as an eddy current sensor. Based on these measured values, feedback control of the position, orientation, and / or angular orientation of the heating strip 110 in the strand 28 and thus in the rod-shaped article can be performed. To adjust or correct the position of the heating strip 110, the position, orientation, and / or angular orientation of the feed device 108 is changed or adjusted accordingly. Such adjustment can be performed with feedback and / or automatically, allowing for automatic quality adjustment and optimization. The illustrated arrangement 50 is designed such that the material flow collected on the support side of the suction line conveyor 17 is transferred and / or transferred in the transfer area 39, the position of which is indicated by a dashed line, to the format inlet area, in which the format belt 24 is guided almost flatly or on a concave surface with a large radius. The transfer does not take place directly to the format belt 24, but rather to the wrapping material strip 21 guided on the format belt 24. The machine 100 is configured as follows in this area. Viewed in the material flow direction M, in the transfer area 39, the suction line conveyor 17 overlaps the format inlet area, and in particular the format belt 24. Furthermore, the arrangement 50 is designed such that the distribution unit 102 comprises a first drive (not shown in the figure) which drives at least the suction strand conveyor 17. The strand forming unit 104 comprises a second drive (also not shown in the figure) which drives at least the format belt 24. The first and second drives are designed, for example, as individual drives. In other words, there is no torque-transmitting mechanical coupling between the two drives. However, a common drive can also be provided. However, the arrangement 50 comprises, in particular, a control unit (not shown), with which the operating speeds of the first and second drives and thus a conveying speed of the suction strand conveyor 17 and a possibly deviating further conveying speed of the format belt 24 are adjusted to one another. Furthermore, it is provided, for example, that the wrapping material feed unit of the strand forming unit 104 has a third drive. This third drive is arranged and configured to feed the wrapping material strip 21 at a specific speed. The wrapping material strip 21 is arranged between the format belt 24 and the material flow.This third drive can also be configured as a single drive. Again, in particular, no torque-transmitting mechanical coupling to the first and / or second drive is provided. According to a further embodiment, however, the first to third drives can be mechanically and torque-transmittingly coupled to one another, thus eliminating the need for individual drives. As already mentioned, the suction line conveyor 17 has a carrying side onto which the aerosol-forming material is sprayed. Opposite this, the suction line conveyor 17 has a running side. The running side of the suction line conveyor 17, for example a suction belt, is guided around an inlet roller 40 and an outlet roller 42. Furthermore, the suction line conveyor 17 can be guided over a deflection element on its carrying side 52. Fig. 2 shows a schematic representation of an arrangement 50 of the tobacco processing industry, comprising a distribution unit 102 and a downstream strand forming unit 104. The limits of the The distribution unit 102 and the strand forming unit 104 are indicated by a dash-dotted line. Furthermore, the arrangement 50 has a feed device 108, which is designed to feed the inductively heatable endless heating strip 110 to the material stream 54 that is sprayed onto the support side 52 of the suction strand conveyor 17 in the region of the suction channel 16, the cheeks of which are not shown. The material feed of the aerosol-forming material is indicated by upward arrows pointing in the direction of the support side 52 of the suction strand conveyor 17. Also shown schematically is the material stream 54, the height of which increases in the material flow direction M. The heating strip 110 is fed to the material stream 54 from an inlet roller 40 of the suction strand conveyor 17. The heating strip 110 is, for example, unrolled or pulled off a reel, preferably pulled off by means of a pull-off unit, in particular in the form of a pair of rollers.The material stream 54, which is drawn up in the area of ​​the suction channel 16, is trimmed to the desired height using a trimming device 19, which is exemplary in two-stage design. The trimmed material stream 54, in which the heating strip 110 is embedded, passes from the suction strand conveyor 17 in the area of ​​a press disk or compactor disk 56 into a format inlet area 58 of the format unit 26, which is formed as part of the strand forming unit 104. The compressor disc 56 also serves as the discharge roller 42 for the suction line conveyor. In the transfer area 39, as already explained in connection with Fig. 1, the suction strand conveyor 17 of the distribution unit 102 overlaps the format inlet area 58 and in particular also the format belt 24 of the format unit 26. The format belt 24 is shown more schematically and only in sections. To ensure the most complete transfer of the material flow 54 from the distribution unit 102 to the strand forming unit 104, the format unit 26 comprises, in addition to the inlet hopper 58, a arranged scraper 60, which ensures that any material adhering to the suction line conveyor 17 is released from it and reaches the format inlet area 58. Fig. 3 shows a schematic view of another arrangement 50, comprising a distribution unit 102 and a strand forming unit 104. The structure of this arrangement 50 has already been explained in connection with Fig. 2, wherein the corresponding components are provided with the same reference numerals. In contrast to the construction explained in connection with Fig. 2, in the arrangement 50 shown in Fig. 3, the heating strip 110 is not fed from the inlet roller 40 of the suction strand conveyor 17, i.e. not in the area of ​​the inlet roller 40 (cf. Fig. 1), but in the area of ​​the suction channel 16. After a certain amount of aerosol-forming material has initially been sprayed onto the support side 52 of the suction strand conveyor 17, the material flow 54 partially produced in this way is trimmed to the desired height using a further trimming device 20.The heating strip 110 is placed on this pre-trimmed material stream 54 in the area of ​​the suction channel 16 or partially inserted into it. Subsequently, additional aerosol-forming material is sprayed onto it until the material stream 54 finally leaves the suction channel 16 and is trimmed to the desired final or target height by the trimming device 19. The heating strip 110 can be introduced into the material stream 54 in different orientations. This is explained using the schematically simplified cross-sectional views in Figs. 4 and 5, each of which shows a schematically simplified cross-section through the suction channel 16. Channel cheeks 62 are shown, the inner sides 64 of which delimit the suction channel 16. The suction line conveyor 17 extends within the suction channel 16, and the material stream 54 is drawn onto its support side 52. The heating strip 110 is partially embedded or located on the upper side of the material stream 54 facing away from the support side 62. Fig. 4 shows the heating strip 110 in a 90° orientation. It is placed with one of its large flat sides on the upper side of the material flow 54. The width of the heating strip 110 is less than the distance between the channel cheeks 62 or the distance between the inner sides 64. The distance between the channel cheeks 62 or the distance between the inner sides 64 is dimensioned such that at least one, preferably both, lateral boundary edges of the heating strip have a distance, preferably greater than 0.5 mm, particularly preferably greater than 0.8 mm and preferably less than 3 mm, particularly preferably less than 2.5 mm, from the adjacent channel cheek(s) 62 or from the adjacent inner side(s) 64.The design with such a distance allows a secure holding of the heating strip 110 and a maintenance of a negative pressure for sucking in further material even in view of a relatively flat coverage of the porous, already dispersed fiber cake by the applied, in particular flat, heating strip 110. Such a situation occurs, for example, in the arrangement 50 shown in Fig. 3, when the heating strip 110 is placed with the feed device 108 located in the suction channel 16 onto the surface of the partially produced material stream 54 trimmed by means of the further trimming device 20. Fig. 5 shows the heating strip 110 in a 0° orientation. Such a configuration is created, for example, in the arrangement 50 shown in Fig. 2 when the heating strip 110 is introduced into the material stream 54 by means of the feed device 108 in an orientation perpendicular to the support side 52 of the suction line conveyor 17. In both cases, with increasing material flow direction M, further aerosol-forming material is showered up, so that the height of the material flow 54 increases and the heating strip 110 is completely embedded at the end of the suction channel 16. Fig. 6 shows schematic representations of different orientations of the heating strip 110 in the material stream 54 or in the strand 28. The left-hand representation of the partial figures, labeled a) to c), shows the orientation of the heating strip 110 in the material stream 54. To the right of this, the corresponding orientation of the heating strip 110 in the strand 28 produced from this material stream 54 is shown. On the right-hand side, the degrees of the orientations of the heating strip 110 are indicated. Thus, Fig. 6a) shows a 90° orientation of the heating strip 110 in the material stream 54 and in the strand 28. Fig. 6b) shows a 0° orientation of the heating strip 110 in the material stream 54 and in the strand 28. Finally, Fig. 6c) shows a 45° orientation of the heating strip 110 in the material stream 54 and in the strand 28. The 90° and 0° orientations have already been explained in connection with Figs. 2 to 5. Subsequently, an arrangement 50 will be explained in which the 45° orientation of the heating strip 110 can be realized.Regardless of the specific examples, any other orientation of the heating strip 110 is possible and intended, i.e., any orientation between the 90° orientation and the 0° orientation. The 45° orientation of the heating strip 110 is merely an example. Fig. 7 shows a schematically simplified cross-sectional view through the suction channel 16 of an arrangement 50 in which the suction channel 16, including the suction line conveyor 17 guided in the suction channel 16, is arranged rotated at a 45° angle. This can be realized, for example, in an arrangement 50 as shown in Fig. 2 or 3. The complete structural unit, i.e. in particular all elements forming the suction channel 16, such as the channel cheeks 62, are arranged obliquely, viewed in a plane transverse, in particular perpendicular, to the material flow direction M with respect to the format belt 24 guided in the format channel 25, viewed in the format inlet area 58. The 45° orientation shown is merely an example. The oblique orientation results in the support side 52 of the suction line conveyor 17 forming an angle with a surface of the format belt 24.Since the format belt 24 is successively rolled up in the format unit 26 in the material flow direction of the strand 28 for the purpose of strand forming, for the aforementioned. Orientation is based on the format inlet area 58 of the suction channel 16, which is located in the transfer area 39, since here the format belt 24 is approximately flat or guided. Fig. 8 shows a schematically simplified cross-sectional view through the suction channel 16 of an arrangement 50 having a trimming device arranged and configured to trim the material flow 54 in an inclined plane. For example, the further trimming device 20 of the arrangement 50 shown in Figs. 2 and 3 can be arranged at a corresponding angle so that the heating strip 110 can be placed on the material flow 54 trimmed at an angle. In order to completely embed the heating strip 110, additional material is then showered onto the obliquely trimmed material flow 54. The material flow 54 is trimmed, for example, in a plane that is arranged obliquely to the support side 52 of the suction line conveyor 17, in particular encloses an angle with the support side 52 of the suction line conveyor 17 that is at least approximately 45°. According to a further embodiment, the arrangement 50 comprises a distribution unit 102 with a divided suction channel 16 and an associated divided nozzle recess 66, and in particular a single suction line conveyor, for example, a single suction belt. The single suction line conveyor, in particular, is designed and configured to receive material from the divided suction channel 16 and the parts of the divided nozzle recess 66. Fig. 9 shows a simplified detailed view of such a distribution unit 102. Below the suction line conveyor 17 is the divided nozzle trough 66, which comprises a first partial nozzle trough 66a and a second partial nozzle trough 66b. With the help of the partial nozzle troughs 66a, 66b, aerosol-forming material can be sprayed in different areas onto the in particular single suction line conveyor 17 running in the suction channel 16. The arrangement 50 comprises in particular a single suction line conveyor 17, which extends transversely to the material flow direction. M extends over both the first partial nozzle recess 66a and the second partial nozzle recess 66b. Fig. 10 shows a schematically simplified cross-sectional view through a split suction channel 16, as can be realized in the distribution unit 102 shown in Fig. 9. In the cross-sectional view shown, it is visible that the suction line conveyor 14, for example a suction belt, extends both in the region of the first partial nozzle trough 66a and in the region of the second partial nozzle trough 66b in a direction transverse to the material flow direction M, which in the illustration in Fig. 10 is perpendicular to the plane of the paper. Via the partial nozzle troughs 66a, 66b, as indicated by arrows, a first mass flow M1 of aerosol-forming material is fed to the first partial suction channel 16a. A second mass flow M2 of aerosol-forming material is fed to the second partial suction channel 16b. In this way, separate material streams, specifically a first partial material stream 54a and a second partial material stream 54b, can be generated.In order to divide the suction channel 16 of the distribution unit 102 into the first partial suction channel 16a and the second partial suction channel 16b, a partition wall 68 is arranged in the suction channel 16. The partition wall 68 extends in the material flow direction M and divides the suction channel 16, at least in sections, into the first partial suction channel 16a and the second partial suction channel 16b. The in particular single suction line conveyor 17 extends transversely and / or longitudinally across the first partial suction channel 16a and the second partial suction channel 16b. Viewed in a plane transverse to the material flow direction M, the partition wall 68, also viewed in cross section, extends at least approximately centrally in the suction channel 16, so that the partial suction channels 16a, 16b are approximately the same size. The partial nozzle recesses 66a, 66b are configured to supply aerosol-forming material into the corresponding partial suction channels 16a, 16b. Specifically, the first partial nozzle recess 66a is arranged and configured to supply a first material flow M1 of aerosol-forming material to the first partial suction channel 16a. The second partial Nozzle recess 66b is arranged and designed to supply a second material flow M2 of aerosol-forming material to the second partial suction channel 16b. The first partial nozzle recess 66a and the second partial nozzle recess 66b extend, viewed in the material flow direction M, in particular in different regions of the suction channel 16. The same applies to the partial suction channels 16a, 16b. In particular, the first partial suction channel 16a extends, viewed in the material flow direction M, in a different, in particular non-overlapping, region than the second partial suction channel 16b. It can be provided, in particular, that one of the two partial suction channels 16a, 16b is initially supplied with aerosol-forming material, and further downstream, the other partial suction channel 16a, 16b is supplied. To ensure that aerosol-forming material reaches the corresponding partial suction channel 16a, 16b at the desired position, the partial suction channels 16a, 16b can be closed by means of suitable cover plates 70 in the areas where they are not to be fed. Fig.Figure 10 shows an example of such a cover plate 70 in cross-section. It closes the first partial suction channel 16b, for example, so that no air flow is applied to a supporting side of the suction line conveyor 17 located below, and consequently no material is blown up. Furthermore, the partition wall 68 can be supported by one or more support elements 46 on one channel cheek 62 or both channel cheeks 62. Fig. 11 shows a schematically simplified plan view of a suction channel 16, in which a partition wall 68 extends, which divides the suction channel 16 into the first partial suction channel 16a and the second partial suction channel 16b. The partition wall 68 is also designed as a feed device 108. For this purpose, it comprises, for example, a groove or a channel in which the heating strip 110 is guided, in particular with play, in particular limited in its movement transversely to its transport direction by three or four walls. This is also partially shown in the cross-sectional view of Fig. 10. At the material flow direction At the furthest downstream end of the partition wall 68, the heating strip 110 is transferred into the material stream 54. At this position, the first partial material stream 54a, which was drawn into the first partial suction channel 16a, and the second partial material stream 54b, which was drawn into the second partial suction channel 16b, merge. At the furthest downstream end of the partition wall 68, at which the heating strip 110 is transferred into the material stream 54, an additional guide for the heating strip 110 can be provided. This guide is designed, for example, as a baffle or the like. This serves to precisely position the heating strip 110 in the material stream 54. Furthermore, it is particularly provided that this additional guide for the heating strip 110 is adjustable. Fig. 11 shows a schematically simplified plan view of the top side of the suction channel 16, looking toward the running side 44 of the suction line conveyor 17 (not shown). The partial suction channels 16a, 16b are partially covered with cover plates, specifically with a first cover plate 70a and a second cover plate 70b. The first cover plate 70a closes the first partial suction channel 16a in an upstream region. The second cover plate 70b closes the second partial suction channel 16b in a further downstream region. For example, the second cover plate 70b only partially closes the second partial suction channel 16b in this region. The cover plates 70 can be designed to be adjustable, in particular adjustable transversely to the longitudinal extent of the suction line conveyor 17, so that the supply of aerosol-forming material to the respective partial suction channels 16a, 16b can be variably controlled or regulated.By appropriate positioning of the cover plates 70a, 70b, it can be achieved that the partial suction channels 16a, 16b extend in different areas. According to a further embodiment, the arrangement 50 comprises a mass measuring device 72. This is shown in Figs. 12 and 13. Shown are simplified cross-sectional views of a split suction channel 16, each with an integrated mass measuring device 72. The mass measuring device 72 is arranged and configured to measure a mass of the material flow 54 that is transported in the suction channel 16. By way of example, the mass measuring device 72 in the illustrated embodiments is arranged and configured to measure a mass of the second partial material flow 54b transported in the second partial suction channel 16b. In the embodiment shown in Fig. 12, the mass measuring device 72 is a microwave measuring device integrated into the channel cheek 62 adjacent to the second partial suction channel 16b. In Fig. 12, the transmitter 74 of the microwave measuring device is integrated into the channel cheek 62. The associated receiver 76 is integrated into the partition wall 68. In the embodiment shown in Fig. 13, the mass measuring device 72 is also embodied, for example, as a microwave measuring device. In this case, a transmitting / receiving unit 78 is integrated into the channel cheek 62. The partition wall 68 includes a suitable reflector 80. The first cover plate 70a and also the support element 46, already mentioned in connection with Fig. 10, are shown as examples. The arrangement 50 can further comprise a mass flow supply control (not shown), which is arranged and configured to control and / or regulate the first mass flow M1, which is supplied to the first partial suction channel 16a, and / or the second mass flow M2, which is supplied to the second partial suction channel 16b. This mass flow supply control can in particular be coupled to the mass measuring device 72, so that, based on a measured value for the mass of the material flow 54 in the first and / or second partial suction channel 16a, 16b measured by the mass measuring device 72, the mass flow supply control device can be controlled and / or regulated accordingly. For example, the mass flow supply control device the cover plates 70a, 70b are controlled and / or regulated accordingly so that the desired mass flow is present in the corresponding partial suction channels 16a, 16b. According to a further embodiment, the arrangement 50 is further developed by a suction air throttle which is arranged and configured to control or regulate at least in sections a suction air flow applied to the suction line conveyor 17 in the suction channel 16. Fig. 14 shows a schematically simplified representation of such a suction air throttle, which is designed using corresponding throttle plates. Shown is a plan view of an upper side of the suction channel 16 facing away from the support side 52 of the suction line conveyor 17, on which upper side the suction air throttle device is preferably arranged and present. The suction channel 16 extends between the channel cheeks 62, and the suction line conveyor 17 is guided in the suction channel 16. At the upper side, a vacuum suction air supply to the suction channel 16, viewed transversely to the material flow direction M, can be changed using a movable throttle plate 82. The throttle plate 82 is, as indicated by arrows, movable transversely to the material flow direction M. By changing the width of a gap between the inside of the respective channel cheek 62 and the edge of the throttle plate 82, an air flow passing through the suction channel 16 can be changed and adjusted. The suction line conveyor 17 is only shown in Fig. 14 and omitted in Fig. 15. The suction line conveyor 17 can be covered at least in sections on its running side 44 by the cover plates 70, 70a, 70b, throttle plates 82, 82a, 82b, 82c. In a modification, areas of the suction line conveyor can also be covered by a cover element or several cover elements that are arranged adjacent to the support side 42 of the suction line conveyor 17, preferably adjacent to a channel cheek 62 and / or adjacent to the inner side 64 of a channel cheek 62 and in particular to a channel cheek 62 or to the inside 64 of a channel cheek, in particular contacting. For example, the air flow applied to the suction belt as the suction line conveyor 17 and at least partially flowing through it can be adjusted to the quantity, mass, or type of material being stirred up on the support side 52 of the suction line conveyor 17. If a material with a high flow resistance is to be stirred up, it may be desirable to use a high suction air flow to stir up this material so that the suction power does not decrease too quickly once a certain amount of material has accumulated on the support side 52 of the suction line conveyor 17. Fig. 15 shows a further schematically simplified view of a suction channel 16 in a plan view of a running side 44 of the suction line conveyor 17 facing away from the support side 52. The throttle device comprises a plurality of throttle plates, in particular the throttle plates 82a, 82b and 82c, which are arranged one behind the other in the material flow direction M. The throttle plates, in particular the throttle plates 82a to 82c, are adjustable separately and independently of one another. This makes it possible to set a suction air flow of different sizes in different regions of the suction channel 16. For example, in an upstream region in which the throttle plate 82c is located and in which a small amount of aerosol-forming material has accumulated on the support side 52 of the suction line conveyor 17, the suction air flow can be set to a relatively low level by closing the corresponding throttle plate 82c.If the amount of aerosol-forming material showered on the support side 52 of the suction line conveyor 17 increases, the air resistance for the suction air flow passing through the showered material increases. For this reason, it may be desirable to increase the suction air flow rate, i.e., the suction air flow flowing through the suction channel 16 in the corresponding area. For this reason, the second throttle plate 82b, which is located downstream of the throttle plate 82c, can be opened wider. Accordingly, the throttle plate 82a located further downstream is opened even further to further increase the suction air flow. The adjustability of the individual throttle plates 82, in particular the throttle plates 82a to 82c, in particular automatic, controlled, regulated, or manual, is provided transversely to the longitudinal extent of the suction line conveyor 17 and is illustrated by corresponding arrows in Fig. 15. Figs. 16a) and 16b) each show schematically simplified cross-sectional views through the suction channel 16 shown in Fig. 15. Fig. 16a) shows the situation along the line labeled AA in Fig. 15. The material flow 54 has spread out relatively far; for this reason, the throttle plate 82a is opened wide to generate a comparatively large suction air flow 84. Fig. 16b) shows the situation along the line labeled BB in Fig. 15. On the suction line conveyor 17, a material flow 54 has spread out at a comparatively lower height. For this reason, the suction air flow 84 can be set lower by closing the throttle plate 82c. The suction air flow passes from the support side 52, on which the material flow 54 is located, through the suction line conveyor 17 in the direction of the running side 44. According to a further exemplary embodiment, the arrangement 50 is further developed in that the supply device 108 is configured such that the heating strip 110 is supplied through one of the channel cheeks 62 delimiting the suction channel 16. The suction channel 16 has a recess which is arranged in a channel cheek 62 and extends continuously through the channel cheek 62, in particular transversely to the longitudinal extent of the suction line conveyor 17, and which is in particular slot-shaped. Fig. 17 shows a schematically simplified side view of an arrangement 50, as already shown in its basic structure in Figs. 2 and 3. Deviating from the arrangement 50 shown in these figures, the feed device 108 is arranged such that the heating strip 110 can be fed in the region of the suction channel 16 through one of the channel cheeks 62 extending in the material flow direction M. Fig. 18 shows a schematic representation of the suction channel 16, which is delimited by the channel cheeks 62 extending in the material flow direction M. The heating strip 110 was fed in a ^" orientation. Since the heating strip 110 can only be bent slightly in a plane in which its large flat sides extend, it is advantageous to provide a twist in the heating strip 110. For this purpose, the feed device 108 comprises a device (not shown) with which such a twist in the heating strip 110 can be realized. Fig. 19 shows a further schematic representation of the suction channel 16, which is defined by the channel cheeks 62, with the heating strip 110 being fed through one of the two channel cheeks 62 in a 0° orientation. When feeding the heating strip 110 in this orientation, a twist is not necessary. Fig. 20 shows a simplified perspective view of a feed device 108, with which the heating strip 110 can be fed through the channel cheek 62 to the material flow 54. The feed device 108 is integrated into the channel cheek 62 and is designed to introduce the heating strip 110 into the suction channel 16. The suction line conveyor 17 guided in the suction channel 16 is not shown in the illustration; visible are support elements 46 provided in the suction channel 16, on which the suction line conveyor 17 is guided. The protective elements 46 together form a support device and ensure that the suction line conveyor 17 is not sucked in the direction of the vacuum source by the negative pressure present in the suction channel 16, but is guided in the desired plane. The support elements can be static, stationary and / or dynamic, rotatable. For example, the support elements 46 around guide rollers on which the suction line conveyor 17 is guided from the running side 44. According to a further embodiment, the suction line conveyor 17 has a clamping device 86 arranged on its support side 52. The clamping device 86 is arranged and configured to hold the heating strip 110 in a clamping grip. According to such an embodiment, the suction line conveyor 17 is not designed as a suction belt with warp and weft threads, but rather has a plurality of segments 88 arranged transversely one behind the other. Fig. 21 shows a simplified perspective view of such a suction line conveyor 17, which additionally has a clamping device 86. The suction line conveyor 17 itself is constructed from a plurality of web-shaped segments 88 arranged transversely one behind the other in a longitudinal direction L of the suction line conveyor 17. The web-shaped segments 88 each have a clamping element 90; the clamping elements 90 of the individual segments 88 act together as a clamping device 86 and hold the heating strip 110, in particular in sections, in a clamping grip. The clamping device 86 is designed and configured to hold the heating strip 110 in a 0° orientation. The individual segments 88 are coupled to one another in a tensile-stable manner. For example, the segments 88 are connected to one another with cables 92, in particular with wire cables. The segments 88 are, for example, injection-molded parts made of a plastic material that are molded around the cables 92. Fig. 22 shows a simplified cross-sectional view through a web-shaped segment 88 of the suction line conveyor 17, whose clamping element 90 is designed as a pair of clamping jaws. It comprises a first clamping jaw 94a and a second clamping jaw 94b. The two clamping jaws 94a, 94b cooperate and hold the heating strip 110 at its mutually opposite large flat sides 96 in a clamping grip. The cross-section shown also shows the cables 92 connecting the individual web-shaped segments 88 to one another, only a few of which are provided with reference symbols. The clamping jaws 94a, 94b forming the clamping element 90 are arranged on the support side 52 of the suction line conveyor 17. The segments 88 of the suction line conveyor 17 are designed to be flexible, for example, such that they can be bent between a closed state and an open state. The clamping element 90, in particular the first and second clamping jaws 94a, 94b, are formed, for example, in one piece with the web-shaped segment 88, in particular in one piece with the segment 88. Fig. 23a) shows a schematic representation of a segment 88 in the closed state, in which the first and second clamping jaws 94a, 94b hold the heating strip 110 in a clamping grip. The web-shaped segment 88 is so flexible that its free ends can be bent downward, as indicated by arrows in Fig. 23a). The free ends are located at the side edges of the suction line conveyor 17. Fig. 23b) shows the web-shaped segment 88 in a bent state. The bending of the web-shaped segment 88 causes the clamping jaws 94a, 94b to open and the clamping handle securing the heating strip 110 to open. In order to specifically bring about the opening of the clamping element 90, the suction line conveyor 17 can be guided over a spherical roller in an area in which the heating strip 110 is to be inserted into the clamping device 86, for example in the area of ​​the inlet roller 40 (see Fig. 1). In other words, the inlet roller can be designed as a spherical roller, which causes the bending of the web-shaped segments 88 described above. The inlet roller 40 designed as a spherical roller can, for example, be provided at the beginning of the suction channel 16, in an area in which the suction line conveyor 17 is or is deflected or a has a linear extension or transitions into a linear extension. The bending of the segments 88 is reversible, and the segments 88 can, in particular, be designed such that they have a restoring force in the direction of the closed state, i.e., they automatically return to the state shown in Fig. 23a (starting, for example, from the state shown in Fig. 23b). In the closed state, the segments 88 extend transversely to the longitudinal direction L of the suction line conveyor 17, at least approximately parallel to a support side 52 of the suction line conveyor 17. In the open state, the free ends are bent out of this plane, which runs at least approximately parallel to the support side 52 of the suction line conveyor 17, so that the pair of clamping jaws opens. According to a further exemplary embodiment, the clamping device 86 can also be realized by arranging individual web-shaped segments 88 laterally offset from the adjacent segments 88. Fig. 24 shows such a clamping device 86 in a schematically simplified plan view of the support side 52 of the suction line conveyor 17. For the sake of simplicity, the gaps otherwise provided between the individual segments 88 are not shown in the figure. The middle segment 88 shown in the figure is arranged laterally offset, i.e., transversely to the longitudinal direction L. This orientation creates a clamping fit between pairs of clamping jaws 94a, 94b of adjacent web-shaped segments 88, which are arranged opposite one another.Specifically, a clamping fit is created between the first clamping jaw 94a of the web-shaped segment 88 shown on the left and the second clamping jaw 94b of the web-shaped segment 88 shown in the middle, which is arranged laterally offset. A further clamping fit is created between this second clamping jaw 94b of the middle web-shaped segment 88 and the first clamping jaw 94a of the web-shaped segment 88 shown on the right. To open this clamping fit, the offset web-shaped segment 88 can be moved laterally, for example with a roller guide 98, so that the. The clamping jaws 94a, 94b of the adjacent web-shaped segments 88 are aligned with one another as long as the offset web-shaped segment 88 is held laterally displaced by the roller guide 98. In this state, the heating strip 110 can be inserted into the clamping device 86. A suction line conveyor 17 equipped with such a clamping device 86 can further be designed such that the offset web-shaped segment 88 automatically returns to the offset position, thus forming the previously described clamping fit. According to a further embodiment not shown, the orientation of the clamping jaws 94a, 94b can be reversibly changed, for example, counteracting the restoring force of a spring element in the manner of a clamp. Thus, the pair of clamping jaws 94a, 94b can be reversibly moved into the closed or open state. In the closed state, the pair of clamping jaws 94a, 94b exerts a clamping force on the large flat sides 96 of the heating strip 110 to provide the clamping grip. In the open state, the clamping element releases the heating strip 110. According to further embodiments, the arrangement 50 comprises at least one heating strip guide device 150, which is arranged and configured to guide the heating strip 110 downstream of the supply device 108. The heating strip guide device 150 is arranged in particular in the region of the distribution unit 102, for example, in its suction channel 16. The heating strip guide device 150 can be designed and configured to guide the heating strip 110 in a 90° orientation. Corresponding embodiments are shown in Figs. 25a) to c). Alternatively, the heating strip guide device 150 can be designed and configured to guide the heating strip 110 in a 0° orientation. The relevant embodiments are shown in Figs. 26a) to d). Fig. 25a) shows a heating strip guide device 150 arranged in the suction channel 16 of the distribution unit 102. The suction channel 16 extends between the channel cheeks 62. The suction line conveyor 17 is guided in the suction channel 16, with the material flow 54 being drawn onto its support side 52. The heating strip 110 is positioned at a 90° angle. The side edges 152 of the heating strip 110 are guided in guide grooves 154 by guide elements 156. One guide element 156 can form the heating strip guide device 150, or two guide elements 156 can jointly form the heating strip guide device 150. One guide element 156 or more guide elements 156 can be received, in particular with a fastening end, in a channel cheek 62. One guide element 156 or more guide elements 156 can be arranged with a free guide end extending from a channel cheek 62 into the suction channel 16. One guide element 156 or more guide elements 156 can be designed and positioned to extend from a channel cheek 62 into the suction channel 16 up to their free guide end or their guide groove 154 over a length of more than 0.8 mm, preferably more than 1 mm and / or less than 3 mm, preferably less than 2.7 mm.A plurality of guide elements 156 can be provided, in particular arranged in a first channel cheek 62 and arranged in a second channel cheek 62, which is opposite the first channel cheek 62, such that the guide elements 156 of the first channel cheek 62 and the second channel cheek are opposite one another or are arranged offset from one another in the direction of the longitudinal extent of the suction line conveyor 17. The two guide elements 156 together form the heating strip guide device 150. The guide elements 156 are aerodynamically shaped so that they offer the lowest possible flow resistance for the material flow 54, particularly in those areas where they come into contact with the material flow 54. In the illustrated embodiment, the guide elements 156 are rounded. and tapered toward their free ends, into which the guide groove 154 is embedded for guiding the side edges 152 of the heating strip 110. The guide elements 156 are held on the channel cheeks 62, for example, embedded in the channel cheeks 62. Fig. 25b) shows another heating strip guide device 150, which is arranged, for example, in the suction channel 16 of the distribution unit 102. For reasons of clarity, the channel cheeks 62 are not shown in the illustration. The heating strip guide device 150 has a pair of rollers, which in turn have a first roller 158a and a second roller 158b. The rollers 158a, 158b have a guide groove 154 extending along their circumference, into which the side edges 152 of the heating strip 110 engage. One roller 158a, 158b or several rollers 158a, 158b can be designed and positioned to extend from a channel cheek 62 into the suction channel 16 up to their free guide end or their guide groove 154 over a length of more than 0.8 mm, preferably more than 1 mm and / or less than 3 mm, preferably less than 2.7 mm.The rollers 158a, 158b are mounted so as to be rotatable about their respective axes 160, for example, they are rotatably received in the channel cheeks 62. The rollers 158a, 158b can be freely rotatable or driven. This ideally results in the lowest possible relative speed between the side edges 152 of the heating strip 110 and the groove base of the guide groove 154, so that a low-wear guidance of the heating strip 110 can be achieved. Furthermore, the rollers 158a, 158b can be designed for optimal flow, resulting in low resistance for the material flow 54, particularly in the area where the material flow 54 comes into contact with the rollers 158a, 158b. Fig. 25c) shows a further heating strip guide device 150, which is provided for guiding the heating strip 110 in a 90° orientation. The heating strip guide device 150 comprises guide discs, specifically a first guide disc 162a and a second guide disc 162b. The heating strip 110 is guided between opposing side surfaces of the guide discs 162a, 162b on its large flat sides 96. The guide discs 162a, 162b, like the previously mentioned rollers 158a, 158b, can be freely rotatable or driven about their axes 160. Fig. 26a) shows a further heating strip guide device 150, which is arranged, for example, in the suction channel 16 of the distribution unit 102. The heating strip 110 is located in a 0° orientation on the support side 52 of the suction line conveyor 17. The channel cheeks 62 are not shown for reasons of clarity. The heating strip guide device 150 comprises a first guide roller 164a and a second guide roller 164b cooperating with the first guide roller. The guide rollers 164a, 164b are in turn designed to be freely rotatable or driven about their respective axes 160. The guide rollers 164a, 164b come into contact with the large flat sides 96 of the heating strip 110 along their outer circumference and thus guide the heating strip 110. The guide rollers 164a, 164b roll along their circumference on the large flat sides 96 of the heating strip 110. Fig. 26b) shows a further heating strip guide device 150 for guiding the heating strip 110 in a 0° orientation. The heating strip guide device 150 is arranged, for example, in the suction channel 16 of the distribution unit 102. The suction channel 16 is laterally delimited by channel cheeks 62, and the suction line conveyor 17 is guided in the suction channel 16. The material flow 54 is spread out on the support side 52 of the suction line conveyor 17. The heating strip 110 is guided in a groove between two guide elements 168. The guide elements 168 are, for example, part of a guide lance that extends into the suction channel 16 for inserting and positioning the heating strip 110. Such a guide lance can also be supported by means of a holding device 170, so that, for example, fluttering of the free end of the guide lance can be prevented. Fig. 26c) shows a schematically simplified side sectional view of another heating strip guide device 150, which is designed as a guide wheel 172. The guide wheel 172 comprises a circumferential guide groove 154 into which a side edge 152 of the heating strip 110 engages, allowing the heating strip 110 to be guided on one side. For this purpose, the guide wheel 172 is designed to be freely rotatable about its axis 160 or is driven accordingly. Fig. 26d) shows this heating strip guide device 150 in a schematically simplified cross-sectional view through the suction channel 16. The material flow 54 is directed onto the support side 52 of the suction line conveyor 17. Furthermore, the heating strip 110 is positioned on the support side 52 of the suction line conveyor 17. The opposite side edge 152 of the heating strip 110 is guided in the guide groove 154 of the guide wheel 172. Fig. 27 shows an arrangement 50 whose basic structure is already known from Figs. 2 and 3. However, unlike the arrangements 50 shown in these figures, the arrangement 50 shown in Fig. 27 has a feed device 108 which is arranged and configured to feed the heating strip 110 to the material stream 54 downstream of the suction channel 16 and upstream of the format channel 25. In the illustrated embodiment, the feed device 108 is arranged between the trimming device 19 and the format channel 25, so that the heating strip 110 is fed to the trimmed material stream 54. Fig. 28 shows a transfer end 175 of the feed device 108 in a schematically simplified cross-sectional view in plan view. The material flow 54 is guided between the suction channel 16 and the format channel 25 in a transport channel 174, which is delimited by transport channel cheeks 173. Material flow transport aids 176 are arranged on the inner sides of the transport channel cheeks 173, which are described in detail further below. The transfer end 175, at which the heating strip 110 is transferred into the material stream 54, has a plow-like design. This allows the aerosol-forming material present in the material stream 54 to be displaced with reduced frictional resistance, and the heating strip 110 can be embedded in the material stream 54. For this purpose, the transfer end 175 has a plow-like tip 180. The transfer end 175 inevitably displaces material. The material flow transport aids 176 support the material transport and can prevent areas of undesirably high density, empty spaces, or even blockages. For example, the material flow transport aids 176 have air transport channels 178 embedded in the transport channel cheeks 173, only some of which are provided with reference symbols. Compressed air, for example, is blown into the transport channel 174 through the air transport channels 178, thus supporting the material transport in the material flow direction M. Fig. 29 shows a schematically simplified side sectional view of the feed device 108 already known from Fig. 28. The transfer end 175 is considered to be the part of the feed device 108 that comes into contact with the material stream 54. The plow-like tip 180 of the transfer end 175 is also visible in the side view of Fig. 29. The heating strip 110 is fed via a transfer wheel 182. Fig. 30 shows a schematically simplified sectional view of the feed device 108 already explained in connection with Figs. 28 and 29. The transfer wheel 182 shown is mounted for rotation about the axis 160. The transfer wheel 182 can be freely rotatable or driven. In the illustrated embodiment, the transfer wheel 182 serves to transfer the heating strip 110 in a 90° orientation. According to a further embodiment not shown, the transfer wheel 182 can also be designed to transfer the heating strip 110 in a 0° orientation. For this purpose, a A suitable groove is provided in the transfer wheel 182, in which the heating strip 110 is guided. Since such a transfer requires a bend of the heating strip 110 in a plane parallel to its large flat sides 96, a heating strip 110 as shown in Fig. 31 can be used. The heating strip 110 shown in Fig. 31 comprises individual segments 184 that are connected to one another via webs 185. Such a heating strip 110 is inserted with the side edge 152 located at the bottom in Fig. 31 into the groove provided in the transfer wheel 182, allowing a corresponding bending of the heating strip 110 in the plane of its large flat sides 96. Furthermore, the segments 184, viewed in the longitudinal direction L of the heating strip 110, can be dimensioned such that each segment 184 fits into a segment cut from the strand 28 for the production of the rod-shaped articles by the tobacco processing industry. The cut between the individual segments intended for further processing is thus preferably made in the region of the webs 185. Figs. 32a) to 32f) show various exemplary embodiments of material flow transport aids 176, each of which is integrated, by way of example, into both transport channel cheeks 173 of the transport channel 174. The figures also show a transfer end 175 of the feed device 108. This is, for example, the transfer end 175 of the feed device 108 described in connection with Figs. 28 to 30 and explained in this context. Alternatively, it is, for example, a feed lance. For reasons of clarity, the heating strip 110 is not shown in each case. The transfer takes place immediately upstream of the format inlet area 58 of the strand forming unit 104. Fig. 32a) shows an embodiment in which the material flow transport aid 176 is implemented using conveyor belts 186. These are guided over deflection rollers and, in particular, are driven. The conveyor belts 186 support the material transport in the material flow direction M. and form the transport channel cheeks 173 in the area of ​​the material flow transport aid 176. The supporting transport of the material flow 54 occurs in the direction illustrated by arrows. Fig. 32b) shows an embodiment in which, as already mentioned in connection with Figs. 28 and 30, air transport channels 178 are integrated into the transport channel cheeks 173. In this way, an air flow directed in the material flow direction M and illustrated in the transport channel 174 by arrows can be generated in the transport channel 174, which also supports the material transport. In the embodiment shown in Fig. 32c), the transport channel cheeks 173 are designed to vibrate. For example, ultrasonic generators are integrated into the transport channel cheeks 173 for this purpose. The vibration also supports the material transport in the material transport direction M and prevents jams of the material to be transported from occurring in the transport channel 174 in the area of ​​the material flow transport aid 176. Fig. 32d) shows an embodiment in which the transport channel cheeks 173 and the transfer end 175 of the feed device 108 are provided with a friction-reducing coating 188. According to further embodiments not shown, only the inner side of the transport channel cheeks 173 facing the transport channel 174 can be provided with a friction-reducing coating 188. Furthermore, it can be provided that only the transfer end 175 is provided with the friction-reducing coating 188. Fig. 32e) shows an embodiment in which the transport channel cheeks 173 are designed as screw conveyors 190. The rotation of the screw conveyors 190, indicated by arrows, supports the material transport in the material flow direction M. This is indicated by arrows in the transport channel 174. Fig. 32f) shows an embodiment in which fluid channels 192 are embedded in the transport channel cheeks 173. These are provided for the discharge of a friction-reducing fluid toward the transport channel 174. For example, alcohol can be used as the friction-reducing fluid. Fig. 33 shows a further embodiment, which illustrates that the transfer end 175 of the feed device 108 can also be designed as a material flow transport aid 176. In connection with Fig. 32d), it was already mentioned that the transfer end 175 can be provided with a friction-reducing coating 188. Fig. 33 shows that the transfer end 175 can be designed to vibrate, so that this also contributes to reliable transport in the material flow direction M in the transport channel 174 in the region of the transfer end 175. According to a further embodiment, the arrangement 50 is further developed by a material flow transfer device 194. Fig. 34 shows two embodiments in schematically simplified side sectional views. Fig. 34a) shows a transfer area 39 of the arrangement 50, in which the material flow 54, which is present on a support side 52 of the suction line conveyor 17, is transferred to the format belt 24, which runs within a format inlet area 58. In fact, the transfer takes place to a wrapping material strip 21 guided on the format belt 24. In this area, the heating strip 110 (not shown in the figures) is introduced into the material flow 54 by means of the transfer end 175 of the feed device 108. To support the material transport in the material flow direction M, a material flow transfer device 194 is provided. In the embodiment shown in Fig. 34a), the material flow transfer device 194 is designed as a compressed air conveying unit 190. Compressed air can be introduced through the channels schematically indicated in this component to support material transport in the direction of the material flow 54. In the embodiment shown in Fig. 34b), a conveyor belt 186 is provided as the material flow transfer device 194. Fig. 35 shows an arrangement 50 according to a further embodiment, the basic structure of which is already known from Figs. 2 and 3. In contrast to the arrangements 50 explained there, the arrangement 50 shown in Fig. 35 has a feed device 108 arranged and configured to feed the heating strip 110 to the partially preformed material stream 54 in the region of the strand forming unit 104. The heating strip 110 is fed into the partially preformed material stream 54 in the region of the format channel 25, more precisely in the region of the format inlet area 58 of the strand forming unit 104. Fig. 36 shows an exemplary feed device 108 provided in such an arrangement 50, which is a feed wheel 196. The feed wheel 196 is arranged in the region of the format inlet area 58. The heating strip 110, which is not shown in Fig. 36 for reasons of clarity, is guided along the outer circumference 198 of the feed wheel 196 so that the heating strip 110 can be fed to the strand 28 in the region of the format inlet area 58. For this purpose, the format inlet area 58 is designed, for example, as a split format inlet area 58. In this way, the partially preformed material stream 54 can avoid the part of the feed wheel 196 acting as the transfer end 175. The transfer end 175 is considered to be the part of the feed wheel 196 that comes into contact with the partially preformed material stream 54. Fig. 37 shows a schematically simplified cross-sectional view, longitudinal to the material flow direction M, viewed from the top. Shown is the insert wheel 196 designed as a feed device 108. The partially preformed material flow 54 is first guided by a plow-like tip 180 deflected. To allow the displaced material to escape, the format inlet area 58 or the format channel 25 has a cross-sectional widening 200 in this area. Thus, space can be created for the heating strip 110 in the material of the partially preformed material stream 54 in the area of ​​the transfer end 175 of the insertion wheel 196, so that the heating strip can be inserted into the partially preformed material stream 54. Subsequently, i.e., further downstream, the material closes around the heating strip 110 without creating gaps, blockages, or the like. Fig. 38 shows a schematically simplified longitudinal section through a feed device 108, in which the heating strip 110 is also fed in the area of ​​the format inlet area 58 or the format channel 25. The heating strip 110 is fed by means of a feed lance 202. The feed lance 202 necessarily displaces material. The feed lance 202 or the inner sides of the format channel 25 can be provided with deflector elements 204, which cause a portion of the material flow 54 to be transported in a direction away from the format belt 24, as indicated by arrows. The deflection elements 204 are an example of a conveying device with which the described effect can be achieved. The conveying device can also be configured similarly to that described in connection with Figs. 32a to f) for the transport channel cheeks 173. Fig. 39 shows two exemplary embodiments of heating strip guide devices 150, which, unlike the heating strip guide devices 150 explained in the context of Figs. 25 and 26, are not arranged in the suction channel 16, but rather in the format inlet area 58 or in the format channel 25. Two heating strip guide devices 150 are shown as examples, which serve to guide the heating strip 110 in a 90° orientation. The heating strip guide devices 150 can also be configured to guide the heating strip in a 0° orientation. For this purpose, the corresponding guide would be arranged rotated by 90°. For example, it is provided that the heating strip 110 is guided in a groove provided for this purpose, with one of the large flat sides 96 of the heating strip 110 being guided flatly on one side. To minimize the flow resistance in the format channel 25, the guide device is held centrally in the format channel 25, for example, by means of a narrow holding element 206, which can additionally be shaped for optimal flow. Fig. 39a) shows a rigidly mounted heating strip guide device 150. The heating strip guide device 150 shown in Fig. 39b), on the other hand, is designed to be adjustable. This adjustability affects, for example, the distance from the format belt 24, i.e., the height, as well as lateral adjustability or a possible tilting of the orientation of the heating strip 110. Fig. 40 shows a schematically simplified cross-sectional view of a heating strip 110 embedded in the material flow 54, which is deformed in a direction transverse to its large flat sides 96. For example, the heating strip 110 has grooves running along its longitudinal direction or is embossed at least in sections. The embossing can be locally limited or extend along the entire length of the heating strip 110. Fig. 41 shows embodiments of the heating strip 110 as it can be processed in an arrangement 50 according to the aforementioned embodiments. Fig. 41a) shows a heating strip 110 which, similar to the heating strip 110 already described in connection with Fig. 31, comprises segments 184 connected by webs 185. Such a heating strip 110 can be embedded in the strand 28 such that the subsequent cut occurs in the region of one of the webs 185. This reduces wear on the cutting blade used for the cut. Fig. 41 b) shows another heating strip 110 constructed from segments 184. These are connected to each other by weakened regions 208. In the weakened regions 208, for example, the material thickness of the heating strip is reduced. Fig. 41c) shows another heating strip 110, which has weakened regions 208 located between the segments 184. In this embodiment, the weakened regions 208 are created by perforation. Fig. 41d) shows a heating strip 110, which also comprises successive segments 184, between which lie weakened regions 208. According to this exemplary embodiment, the weakened regions 208 are not perforated regions, but rather, for example, partially perforated or punched regions, so that a material weakening also occurs. Fig. 41e) shows a heating strip 110 which is perforated throughout. Material weakening can also be achieved in this way. Cutting such a heating strip 110, which is embedded in the strand 28, occurs with reduced wear on the cutting blade. In Fig. 41f) a heating strip 110 is shown which is weakened by partial perforation. Fig. 42 shows a schematically simplified sectional view in a plane transverse to the material flow direction M, in which a knife device 31 is shown in sections. This comprises a cutting blade 212 with which the strand 28 is cut to length. The heating strip 110 is embedded in the strand 28. Also shown is a rotation center 214 of the knife device 31. The figure shows the orientation of the heating strip 110 in a ^" orientation to the rotation center 214 of the knife device 31. With respect to the center of rotation 214 of the knife device 31, a cut is made in a vertical direction through the heating strip 110. This orientation, in which the large flat sides 96 of the heating strip 110 lie in a plane which is spanned by a line running along the center of the strand 28, which essentially coincides with the material flow direction M, on the one hand, and by a connecting line between the center of rotation 214 of the knife device 31 and the center of the strand 28, on the other hand, offers the least wear of the cutting blade 212 of the knife device 31. Deviations of the orientation of the heating strip 110 from the previously described orientation, in particular by +-45°, still lead to very good results and are therefore advantageously provided according to further embodiments. Fig. 43 shows a rod-shaped article 216 of the tobacco processing industry, for example, a heat-not-burn article. This comprises a segment 218 of the tobacco processing industry, for example, a tobacco rod, in which a heating strip 110 is arranged. Furthermore, the rod-shaped article 216 comprises, for example, a filter 220. Fig. 43a) shows the rod-shaped article 216 in a schematically simplified longitudinal section, Fig. 43b) shows this article 216 in a cross-section along the segment 218.
