Description

The invention relates to a method for producing rod-shaped products for the tobacco processing industry, in particular segments for heat-not-burn products or filter segments.

The invention further relates to a device for producing rod-shaped products for the tobacco processing industry, in particular segments for heat-not-burn products or filter segments.

The invention also relates to a machine for the tobacco processing industry for producing rod-shaped products for the tobacco processing industry.

It is known in the art that some of the rod-shaped products manufactured in the tobacco processing industry include metal wires. These rod-shaped products include heat-not-burn segments, in which the tobacco is heated using metal wires, for example. Such metal wires are also used in the production of certain filter segments.

Such rod-shaped products can no longer be cut with cutting devices after the metal wires have been introduced into the products, since the cutting devices used for this would become blunt due to the cutting of the products.

A process for producing rod-shaped products for the tobacco processing industry with an inserted metal wire is on pages 59, 60 of the magazine " Prior Art Journal", volume 2017, No. 06 , shown.

US 3,354,887 A shows the processing of double filters by compressing a granular material. The double filters are then cut in the middle.

The object of the invention is to provide a method and a device for producing rod-shaped products for the tobacco processing industry and a machine for the tobacco processing industry, through which the introduction of elongated insertion bodies into rod-shaped segments of the tobacco processing industry is improved.

This object is achieved by a method for producing rod-shaped products in the tobacco processing industry, namely segments for heat-not-burn products or filter segments, with a first longitudinally extending insert body passing through a first end face of a rod-shaped segment and through a second end face of the rod-shaped Segment a second elongated insertion body is introduced into the rod-shaped segment, namely inserted, wherein the first elongated insertion body and the second elongated insertion body are or are arranged in the rod-shaped segment such that the mutually facing front sides of the elongated insertion bodies are spaced from one another in the longitudinal axial direction, the rod-shaped segment after the elongated insertion bodies have been inserted between the front sides of the elongated Insertion body is cut through.

The method according to the invention advantageously accelerates the production of rod-shaped products in the tobacco processing industry by introducing two elongated insert bodies into each rod-shaped segment.

In particular, the rod-shaped segment has twice the useful length. In other words, the rod-shaped segment is twice as long as the end products, for example the filter segments or the segments for heat-not-burn products. Two rod-shaped products are subsequently produced from a single rod-shaped segment.

Preferably, the rod-shaped segment is conveyed transversely axially while the first elongated insertion body is introduced into the rod-shaped segment and/or while the second elongated insertion body is introduced into the rod-shaped segment.

By introducing the elongated insertion bodies into the rod-shaped segment while the rod-shaped segment is being conveyed, a continuous manufacturing process is advantageously realized. The introduction of the elongated insertion bodies during the conveyance of the rod-shaped segment is made possible by the elongated insertion bodies being introduced into the rod-shaped segment through the end faces of the rod-shaped segment and thus from a direction orthogonal to the conveying direction of the rod-shaped segment.

Furthermore, to introduce the first elongated insertion body into the rod-shaped segment, the first elongated insertion body and the rod-shaped segment are moved relative to one another in the longitudinal-axial direction and/or to insert the second elongated insertion body into the rod-shaped segment, the second elongated insertion body and the rod-shaped segment are moved in the longitudinal-axial direction moved relative to each other.

The longitudinal axial direction refers to the rod-shaped segment. In particular, the longitudinal axis of the rod-shaped segment is parallel or identical to the longitudinal axis of the longitudinally extended insertion bodies during the insertion of the elongated insertion bodies into the rod-shaped segment. The relative movement enables the elongated insertion bodies to be inserted quickly and reliably into the rod-shaped segment. Different embodiments of the method are provided for implementing the relative movement.

According to a first embodiment, to introduce the first elongated insertion body into the rod-shaped segment, the first elongated insertion body is inserted into the rod-shaped segment, while the rod-shaped segment is held stationary in the longitudinal axial direction and / or is used to insert the second elongated insertion body into the rod-shaped segment second longitudinally extending insert body is inserted into the rod-shaped segment, while the rod-shaped segment is held stationary in the longitudinal axial direction.

According to a second embodiment, to introduce the first elongated insertion body into the rod-shaped segment, the rod-shaped segment is pushed over the first elongated insertion body, while the first elongated insertion body is held stationary in the longitudinal axial direction and / or is used to insert the second elongated insertion body into the rod-shaped segment the rod-shaped segment is pushed over the second elongated insertion body, while the second elongated insertion body is in is held stationary in the longitudinal axial direction.

According to a third embodiment, to introduce the first elongated insertion body into the rod-shaped segment, the rod-shaped segment and the first elongated insertion body are each moved towards each other and / or to insert the second elongated insertion body into the rod-shaped segment, the rod-shaped segment and the second elongated insertion body are each moved moved towards each other.

In these embodiments, the elongated insertion bodies are introduced into the rod-shaped segment by a corresponding movement of the rod-shaped segment and/or the elongated insertion bodies. This represents a simple and reliable method for inserting the elongated insertion bodies.

The first elongated insertion body and the second elongated insertion body are either introduced into the rod-shaped segment simultaneously or the elongated insertion bodies are introduced sequentially into the rod-shaped segment.

The simultaneous introduction of the elongated insertion bodies makes it possible to insert the insertion bodies in a single process step. If, on the other hand, the elongated insertion bodies are inserted sequentially, it is possible to hold or fix the rod-shaped segment stationary in the respective receiving trough by providing a boundary wall or a side stop while the elongated insertion bodies are inserted. In this way, the insertion of the elongated insertion bodies into the rod-shaped segment is made easier. Alternatively, the elongated insertion bodies are held or fixed in a stationary manner in the respective receiving trough by such a boundary wall or such a side stop, while the rod-shaped segment is pushed over the elongated insertion bodies.

Preferably, after the introduction of the first elongated insertion body and before the introduction of the second elongated insertion body, the rod-shaped segment is longitudinally axially displaced, in particular in the direction of the first end face and/or in particular by at least the length of the second elongated insertion body.

By moving the rod-shaped segment longitudinally axially, the space required for the process in the receiving troughs in the longitudinal axial direction of the rod-shaped segment is advantageously limited to the sum of the lengths of the rod-shaped segment and one of the longitudinally extended insertion bodies.

Preferably, the first elongated insertion body and/or the second elongated insertion body are made of a harder material, in particular metal, than the rod-shaped segment.

The introduction of elongated insert bodies made of metal is intended in particular for segments for heat-not-burn products in the tobacco processing industry. In particular, the electrical conductivity and/or the thermal conductivity of the metal is used to heat the tobacco material of the heat-not-burn product.

Furthermore, the first elongated insertion body and the second elongated insertion body are or are arranged in the rod-shaped segment such that the mutually facing front sides of the elongated insertion bodies in the rod-shaped segment are spaced from one another in the longitudinal axial direction.

The elongated insertion bodies are in particular each shorter than half the length of the rod-shaped segment. By providing a distance between the mutually facing front sides of the elongated insertion bodies in the rod-shaped segment, it is advantageously achieved that the elongated insertion bodies are taken into account the length tolerances do not collide when inserted into the rod-shaped segment.

After the elongated insertion bodies have been inserted, the rod-shaped segment is cut through, preferably in the middle, between the front sides of the elongated insertion bodies.

This advantageously ensures that only the rod-shaped segment is cut in the middle after the elongated insertion bodies have been inserted. In contrast, the elongated insertion bodies are not cut after the elongated insertion bodies have been inserted into the rod-shaped segment, since the cut runs through the rod-shaped segment between the front sides of the elongated insertion bodies, which are spaced apart from one another. This is particularly advantageous if the elongated insertion bodies are made of a harder material than the rod-shaped segment, since in this way blunting of the cutting device used is avoided.

Preferably, the first elongated insertion body and the second elongated insertion body are each cut to a substantially equal length before the elongated insertion bodies are inserted into the rod-shaped segment.

The elongated insertion bodies are cut in particular with cutting devices which are designed for cutting the elongated insertion bodies, in particular made of metal. By cutting the elongated insertion bodies to a substantially equal length, it is achieved that the finished rod-shaped products of the tobacco processing industry also each have elongated insertion bodies of the same length.

Further preferably, the first elongated insertion body and/or the second elongated insertion body have a substantially constant cross-sectional shape along their longitudinal directions, wherein in particular the cross-sectional shape is X-shaped or Y-shaped or star-shaped or ring-shaped.

The cross-sectional shape is advantageously chosen so that the insertion bodies have the largest possible surface area. This is advantageous if the insert bodies are designed as heat conductors by means of which the rod-shaped products are heated. The diameter of the cross-sectional shape of the elongated insertion bodies is in particular smaller than the diameter of the rod-shaped segments so that the elongated insertion bodies are completely accommodated in the rod-shaped segments.

The cross-sectional shape of the first elongated insertion body and/or the cross-sectional shape of the second elongated insertion body are preferably void-free. For example, X-shaped, Y-shaped or correspondingly designed star-shaped cross-sectional shapes meet this requirement. This prevents parts of the rod-shaped segments from being gouged out.

The elongated insertion bodies each have a front and a back, with the insertion bodies preferably being aligned before insertion so that the front sides are aligned in the direction of the rod-shaped segment.

Such an orientation advantageously facilitates the introduction of the elongated insertion bodies into the rod-shaped segment.

The front of the first elongated insertion body and/or the front of the second elongated insertion body are preferably processed, in particular sharpened, before the elongated insertion bodies are inserted into the rod-shaped segment.

When processing the front sides of the elongated insert bodies, they are, for example, sharpened, ground, roughened or with provided with a coating or the like. This processing advantageously facilitates the introduction of the elongated insertion bodies into the rod-shaped segment.

Furthermore, the back of the first elongated insertion body and/or the back of the second elongated insertion body are preferably processed, in particular ground, before the elongated insertion bodies are inserted into the rod-shaped segment.

The back sides of the elongated insert bodies are deburred by machining, especially grinding. In this way, a defined area is provided on which, for example, a pestle can be placed, and the risk of injury to consumers of the products is minimized.

Preferably, after the introduction of the first elongated insertion body, the back of the first elongated insertion body and the first end face of the rod-shaped segment are flush and / or after the insertion of the second elongated insertion body, the back of the second elongated insertion body and the second end face of the rod-shaped segment are flush.

In this way, rod-shaped products are provided with a reproducible positioning of the inserted insert bodies.

The object is also achieved by a device for producing rod-shaped products in the tobacco processing industry, namely segments for heat-not-burn products or filter segments, in particular for carrying out a method according to one or more of the aforementioned embodiments, with a receiving trough for Conveying arrangement having rod-shaped segments for the transverse axial conveying of rod-shaped segments in the receiving troughs along a conveying path, the rod-shaped in a conveying plane Segments next to the conveying path, a first feed for conveying a first elongated insertion body and a second feed for conveying a second elongated insertion body open into the receiving troughs, a first pushing device movable or moved along the receiving troughs for introducing the first elongated insertion body into a first end face of the in rod-shaped segments conveyed in the receiving troughs and a second pushing device movable or moved along the receiving troughs for introducing the second elongated insertion body into a second end face of the rod-shaped segments conveyed in the receiving troughs are provided, the first feed having a first front side processing device, by means of which a front side of the first elongated insertion body can be processed or is processed and / or the second feed has a second front side processing device, by means of which a front side of the second elongated insertion body can be processed or is processed.

The same or similar advantages apply to the device for producing rod-shaped products in the tobacco processing industry as have already been discussed with regard to the method for producing rod-shaped products in the tobacco processing industry.

The device according to the invention advantageously introduces two longitudinally extending insert bodies into each conveyed rod-shaped segment.

In particular, the length of the receiving troughs of the conveyor arrangement is at least as long as twice the useful length of the rod-shaped products.

The feeds for the elongated insertion bodies in particular each open into receiving troughs, the length of which is at least as large as the sum of twice the useful length of the rod-shaped products and the length of one of the elongated insertion bodies. Through the feeders The elongated insertion bodies are arranged next to the rod-shaped segments in the receiving troughs and then introduced into the rod-shaped segments by the pushing devices arranged on or in the receiving troughs.

The conveying path is understood to be the path along which the rod-shaped segments are conveyed in the transverse axial direction in the conveying arrangement.

The conveying level is the level in which the rod-shaped segments are conveyed. This does not necessarily have to be flat, but can also run, for example, along the surface of one or more conveyor drums.

Preferably, the first thrust device is designed as a plunger or as a swash plate and/or the second thrust device is designed as a plunger or as a swash plate.

If the thrust devices are designed as plungers, the plungers realize a relative movement between the rod-shaped segment and the elongated insertion bodies in the longitudinal axial direction of the rod-shaped segments. Alternatively, this relative movement is caused by swashplates.

Preferably, the first feed for the first elongated insertion bodies opens into a first feed section of the receiving troughs and the second feed for the second elongated insertion bodies opens into a second feed section of the receiving troughs, in particular the first feed section and the second feed section being arranged at different ends of the receiving troughs.

In other words, the feed sections are those sections of the receiving troughs into which the feeds open. By arranging the feed sections at different ends of the receiving troughs The conveyor arrangement ensures that the first elongated insertion body can be easily inserted into the first end face of the rod-shaped segment and the second elongated insertion body into the second end face of the rod-shaped segment.

The conveyor arrangement preferably comprises a conveyor drum having receiving troughs or conveyor drums having a plurality of receiving troughs.

The rod-shaped segments are held in the receiving troughs of the conveyor arrangement or the conveyor drums, in particular by means of a negative pressure. In particular, the first feed comprises at least one conveyor drum and/or the second feed comprises at least one conveyor drum.

The conveyor drums achieve a space-saving design of the facility and a high conveying rate.

Preferably, the first pushing device and the second pushing device are arranged one after the other along the conveying path in the conveying direction of the rod-shaped segments, with the first feed opening before or at the first pushing device and the second feed before or at the second pushing device opening into the receiving troughs.

In particular, in the conveying direction of the rod-shaped segments along the conveying path, the first elongated insertion body is first arranged next to the conveyed rod-shaped segment by means of the first feed and is subsequently introduced into the rod-shaped segment by the first pushing device. In the conveying direction after the first pushing device, the second feed opens and arranges the second elongated insertion body next to the conveyed rod-shaped segment. The second elongated insertion body is subsequently introduced into the rod-shaped segment by the second pushing device.

Preferably, the first pushing device is arranged on a first conveyor drum of the conveying arrangement and/or the second pushing device is arranged on a second conveying drum of the conveying arrangement.

By arranging the first pushing device and the second pushing device on different conveyor drums of the conveyor arrangement, a variable structure of the conveyor arrangement is realized, whereby, for example, any number of further conveyor drums can be integrated into the conveyor path of the rod-shaped segments between the first conveyor drum and the second conveyor drum. Alternatively, the first pushing device and the second pushing device are arranged on the same conveyor drum. Such an arrangement of the pushing devices is advantageous if the elongated insertion bodies are inserted at the same time.

According to one embodiment, a third pushing device is arranged on the conveying path in the conveying direction of the rod-shaped segments between the first pushing device and the second pushing device for the longitudinal axial displacement of the rod-shaped segments arranged in the receiving troughs.

The third pushing device moves the rod-shaped segments in particular towards the first end face of the rod-shaped segments. The third pushing device advantageously limits the required dimensions of the receiving troughs, since the displacement of the rod-shaped segments in the receiving trough creates space for receiving the second elongated insertion body on the second end face of the rod-shaped segments.

Preferably, a segment cutting device is arranged on the conveying path for, in particular centrally, severing the rod-shaped segments arranged in the receiving troughs, in particular the segment cutting device in the conveying direction of the rod-shaped segments is arranged after the thrust devices.

By cutting the rod-shaped segments, which preferably have twice the useful length for inserting the elongated insertion bodies, two rod-shaped products are created, each with a single useable length and each with an elongated insertion body. The device thus advantageously produces two finished rod-shaped products, each with an elongated insertion body, from each conveyed rod-shaped segment.

Furthermore, the first feed preferably has a first insertion body cutting device for cutting the first elongated insertion body and/or the second feed has a second insertion body cutting device for cutting the second elongated insertion body.

By means of the first insertion body cutting device and the second insertion body cutting device, the elongated insertion bodies are cut, in particular, to a substantially equal length. By arranging the insertion body cutting device in the feeds, different cutting devices are provided for cutting the rod-shaped segments and cutting the elongated insertion bodies. This is particularly advantageous if the elongated insertion bodies are made of a harder material than the rod-shaped segments, since the cutting devices can be designed to cut the respective materials. Alternatively, a single insert body cutting device is provided for cutting the first elongated insert bodies and for cutting the second elongated insert bodies.

According to the invention, the first feed has a first front side processing device, by means of which a front side of the first elongated insertion body can be processed, in particular sharpened, or is processed, in particular sharpened, and/or has the second feed a second front side processing device, by means of which a front side of the second elongated insertion body can be processed, in particular sharpened, or is processed, in particular sharpened.

Alternatively, a single front side processing device is provided, by means of which the front sides of both elongated insertion bodies can be processed, in particular sharpened, or are processed, in particular sharpened. By processing, in particular sharpening, the front sides of the elongated insertion bodies, the insertion of the elongated insertion bodies into the rod-shaped segments is made easier.

Furthermore, the first feed preferably has a first back side processing device, by means of which a back side of the first elongated insertion body can be processed, in particular grinded, or is processed, in particular ground, and/or the second feed has a second back side processing device, by means of which a back side of the second elongated insertion body can be processed, in particular grinded, or is processed, in particular ground.

Analogous to the front side processing device, a single back side processing device is alternatively provided, by means of which the back sides of both elongated insertion bodies can be processed, in particular grinded, or are processed, in particular ground. By processing, in particular grinding, the back sides of the elongated insert bodies, these back sides are deburred.

Finally, the object is achieved by a machine in the tobacco processing industry for producing rod-shaped products in the tobacco processing industry, comprising a device according to one or more of the aforementioned embodiments.

For example, the machine in the tobacco processing industry is a machine for producing filter cigarettes and the device is a device for producing filter segments.

The same or similar advantages apply to the machine in the tobacco processing industry as have already been discussed with regard to the method for producing rod-shaped products in the tobacco processing industry and/or the device for producing rod-shaped products in the tobacco processing industry.

In the drawings, the same or similar elements and/or parts are provided with the same reference numbers, so that they are not presented again.

Fig. 1 shows a schematically simplified device 1 for producing rod-shaped products in the tobacco processing industry. The device 1 comprises a conveyor arrangement 2 with several conveyor drums 10, 20, 30, 35, 40, 50, 60, 70, each of which has several receiving troughs 12 exhibit. In the receiving troughs 12 of the conveyor drums 10, 20, 30, 35, 40, 50, 60, 70, rod-shaped segments 3 are each conveyed transversely axially and from each conveyor drum 10, 20, 30, 35, 40, 50, 60, 70 respectively a conveyor drum 10, 20, 30, 35, 40, 50, 60, 70 following in the conveying direction is transferred along a conveying path of the rod-shaped segments 3, for example from the conveyor drum 10 to the conveyor drum 20. For reasons of clarity, only one of these receiving troughs 12 and only one rod-shaped segment 3 is provided with a reference number.

Furthermore, the device 1 has a first feed 130 for feeding a first elongated insertion body 6 into the receiving troughs 12 of the conveyor drum 30 and a second feed 140 for feeding a second elongated insertion body 7 into the receiving troughs 12 of the conveyor drum 60 downstream in the conveying direction of the rod-shaped segments 3 . The feeds 130, 140 also each have several conveyor drums 80, 82, 90, 92, with which the elongated insertion bodies 6, 7 are each conveyed transversely axially. The elongated insertion bodies 6, 7 are first cut to a substantially equal length on the conveyor drums 90, 92 by means of an insertion body cutting device 94, 95. The back sides of the elongated insertion bodies are then ground on the subsequent conveyor drums 80, 82 using backside processing devices 86, 87 provided for this purpose, before the elongated insertion bodies 6, 7 are fed to the conveyor drums 30, 60.

The receiving troughs 12 of the conveyor drums 30, 35, 40, 50, 60, 70 are longer than the receiving troughs 12 of the upstream conveyor drums 10, 20 for the rod-shaped segments 3, so that in the receiving troughs 12 of the conveyor drums 30, 35, 40, 50 , 60, 70 both a rod-shaped segment 3 and an elongated insertion body 6, 7 can be arranged next to one another.

The first elongated insertion body 6 is thus placed in the receiving trough 12 of the conveyor drum 30 is arranged next to the rod-shaped segment 3, so that the front side 8 of the first elongated insertion body 6 faces a first end face 4 of the rod-shaped segment 3. Subsequently, both the rod-shaped segment 3 and the first elongated insertion body 6 are transferred to the conveyor drum 35, which in turn transfers the rod-shaped segment 3 and the first elongated insertion body 6 to the conveyor drum 40. On the conveyor drum 40, a first insertion device 42 is arranged in the receiving trough 12, for example a plunger, which attaches to the back 9 of the first elongated insertion body 6. By means of this first insertion device 42, the first elongated insertion body 6 is inserted with the front side 8 first into the first end face 4 of the conveyed rod-shaped segment 3.

The rod-shaped segment 3 is then transferred to the conveyor drum 50, which is, for example, a sliding drum. On this conveyor drum 50, a third pushing device is used, which is in Fig. 1 is hidden due to the perspective view, the rod-shaped segment 3 is displaced in the longitudinal axial direction in the respective receiving trough 12, namely in the direction of the first end face 4.

The rod-shaped segment 3 is then transferred to the conveyor drum 60. On this conveyor drum 60, the second elongated insertion body 7 is arranged next to the rod-shaped segment 3 in such a way that the front side 8 of the second elongated insertion body 7 is aligned in the direction of the second end face 5 of the rod-shaped segment 3. On the subsequent conveyor drum 70, the second elongated insertion body 7 is moved by means of a second pushing device, which is also in Fig. 1 is hidden due to the perspective view, inserted longitudinally axially into the second end face 5 of the rod-shaped segment 3.

In the conveying direction behind the conveyor drum 70 is an in Fig. 1 not shown Segment cutting device arranged, by means of which the rod-shaped segment 3 provided with two insertion bodies 6, 7 is cut in the middle.

To insert the elongated insertion bodies 6, 7, it is alternatively provided that the rod-shaped segment 3 is pushed over the elongated insertion bodies 6, 7 or that the elongated insertion bodies 6, 7 and the rod-shaped segment 3 are moved towards one another. In an alternative embodiment, the first insertion device 42 and/or the second insertion device are designed as swashplates instead of as plungers.

Fig. 2a shows a schematically simplified projection of the conveyor arrangement 2 Fig. 1 in an image plane. The image plane thus corresponds to the conveying plane 150, in which the rod-shaped segments 3 are conveyed transversely axially. In this simplified representation, the rod-shaped segments 3 are moved in the conveying direction 160 from right to left. Transferred to Fig. 1 However, the conveying plane 150 is not flat, but runs along the surfaces of the conveying drums 10, 20, 30, 35, 40, 50, 60, 70.

The conveying path 120, along which the rod-shaped segments 3 are conveyed in the conveying level 150, is in Fig. 2a shown as the area between the two dotted lines. In Fig. 1 the conveyor path 120 is therefore a two-dimensional surface with the width of a rod-shaped segment 3, which also runs along the surfaces of the conveyor drums 10, 20, 30, 35, 40, 50, 60, 70.

Through the in Fig. 2a The selected representation shows the individual process steps for producing the rod-shaped products using the in Fig. 1 shown device 1 clarified. As already in connection with Fig. 1 explained, the first elongated insertion body 6 is first arranged along the conveying path 120 into the receiving trough 12 of the conveying drum 30 next to the rod-shaped segment 3, namely in the first feed section 14 of the receiving trough 12 before the first elongated insertion body 6 is inserted into the rod-shaped segment 3 on the conveyor drum 40 by means of the first pushing device 42. The rod-shaped segment 3 is then displaced longitudinally axially on the conveyor drum 50 by means of the third pushing device 52, before the second elongated insertion body 7 is arranged next to the rod-shaped segment 3 in the second feed section 16 on the conveyor drum 60 and is placed on the conveyor drum 70 by means of the second insertion device 72 the rod-shaped segment 3 is inserted. The rod-shaped segment 3 is then cut through the middle using the segment cutting device 100 on another conveyor drum. The elongated insertion bodies 6, 7 inserted into the rod-shaped segment 3 are in Fig. 2a as well as the following Figs. 2b and 2c each shown with dashed lines.

Fig. 2b shows another embodiment of the conveyor arrangement 2, which is used for a different method for producing the rod-shaped products of the tobacco processing industry. According to this method, after the first elongated insertion body 6 has been inserted into the first end face 4, the rod-shaped segment 3 is turned through 180° by means of a turning device (not shown), namely about an axis of rotation running transversely axially centrally through the rod-shaped segment 3. In the representation in Fig. 2b After this rotation, the first end face 4 is no longer aligned upwards, but the second end face 5. The second elongated insertion body 7 is then inserted into the second end face 5. Both elongated insertion bodies 6, 7 are thus fed to the first feed section 14 in this embodiment.

A further embodiment of the conveyor arrangement 2, which is used for a further method for producing the rod-shaped products of the tobacco processing industry, is shown in Fig. 2c shown. At the in Fig. 2c The conveyor arrangement 2 shown is the receiving troughs 12, into which the feeds 130, 140 open, and the receiving troughs 12 in which the pushing devices 42, 72 are arranged, designed so that they can accommodate the first elongated insertion body 6, the rod-shaped segment 3 and the second elongated insertion body 7 side by side. To produce the rod-shaped products for the tobacco processing industry, the elongated insertion bodies 6, 7 are arranged in these receiving troughs 12 on different sides of the rod-shaped segment 3 and simultaneously inserted by means of the pushing devices 42, 72 before the rod-shaped segment 3 is cut in the middle by means of the segment cutting device 100 .

In the Fig. 3a to 3c The cutting of the rod-shaped segment 3 provided with two elongated insertion bodies 6, 7 is shown schematically. Fig. 3a shows a sectional view through the rod-shaped segment 3 after both longitudinal insertion bodies 6, 7 have been inserted. Fig. 3b shows the illustration Fig. 3a in a perspective view. The back 9 of the first elongated insertion body 6 is flush with the first end face 4 of the rod-shaped segment 3. Analogously, the back 9 of the second elongated insertion body 7 is flush with the second end face 5 of the rod-shaped segment 3. The front sides 8 of the elongated insertion body 6, 7 are spaced apart from each other.

It follows that the lengths of the individual elongated insertion bodies 6, 7 are chosen so that they are each less than half as large as the length of the rod-shaped segment 3.

In the middle between the two longitudinally extended insert bodies 6, 7 is in the Figures 3a and 3b each with a dotted line shows a cutting line along which the rod-shaped segment 3 is cut by means of the segment cutting device 100. Only the rod-shaped segment 3 is cut, but not the elongated insertion bodies 6, 7. This is particularly advantageous if the elongated insertion bodies 6, 7 are made of a harder material than that rod-shaped segment 3 are made, for example from a metal. If the segment cutting device 100 were also used to cut the longitudinally extended insert bodies 6, 7, this would result in the segment cutting device 100 becoming blunt after a short time.

After cutting, two rod-shaped products 102, 104 are created Fig. 3c shown. Each of the rod-shaped products 102, 104 has an elongated insertion body 6, 7 inside. The length of the rod-shaped segment 3 is preferably chosen to be twice the useful length, so that the rod-shaped products 102, 104 each have a single useful length.

Fig. 4 shows schematically simplified various cross-sectional shapes 110, 112, 114, 116 of the elongated insertion bodies 6, 7. In addition to the one in the Figures 1 In the cross-shaped or Regardless of the cross-sectional shape used, the diameter of the elongated insertion bodies 6, 7 is smaller than the diameter of the rod-shaped segments 3, so that the elongated insertion bodies 6, 7 are completely accommodated in the rod-shaped segment 3.

In Fig. 5 In a schematically simplified form, an elongated insertion body 7 is shown, the front side 8 of which has been sharpened with a front side processing device 84. In this way, the insertion of the elongated insertion bodies 6, 7 into the rod-shaped segment 3 is simplified. Such a front side processing device 84 can be arranged, for example, on the conveyor drums 80, 82 in order to process the front sides 8 of the conveyed elongated insert bodies 6, 7.
