Description

The invention relates to a method for processing rod-shaped Articles of the tobacco processing industry, where the articles on a Transfer conveyor be provided by the Transfer conveyor to at least one processing drum for Editing the article will be passed, and during a through the processing drum takes place promoting the article edited become.

The invention further relates to a device for processing rod-shaped articles of the tobacco processing industry, with a Transfer conveyor for receiving the articles, and with at least one the transfer conveyor associated processing drum for Picking up the items from the transfer conveyor and editing the article during a through the processing drum taking place Promotion of the article.

Under rod-shaped articles of the tobacco processing industry here in particular cigarettes, cigarette filters or tobacco sticks for Cigarettes, for example tobacco sticks from cut tobacco, understood.

Methods and devices of the type mentioned are from the Known in the art. For example, EP 0 432 663 shows B1 a device for perforating filter cigarettes. The Filter cigarettes become a first along a feed drum Transfer drum promoted. Part of the cigarettes on the Transfer drum is transferred from the transfer drum to a first Pass perforation drum and after perforation to a first Promoted delivery drum. The rest of the cigarettes will be from the first one Transfer drum delivered to a second transfer drum, too promoted a second perforation drum and after the perforation from the second perforating drum to a second dispensing drum delivered the cigarettes of the first dispensing drum.

WO 03/043449 A1, for its part, shows a filter attachment machine which from a main drum and several other associated ones Drumming exists. On the main drum are elements of the Filter cigarettes, namely tobacco sticks or parts, filter pieces, Cigarette units and made of these filter cigarettes transported. With the help of a pick-up drum are from each other shifted parts with inserted filter piece for attachment a tipping paper transported outside the main drum, interconnected and with the help of a return drum as one-piece cigarette units are returned to the main drum.

Object of the present invention is to the prior art improve.

This object is achieved according to the present invention by the Objects of the independent claims solved.

An important advantage of the present invention is that - contrary the prior art - to feed the article to the Processing drum and for the removal of the articles from the Processing drum only a single transfer conveyor instead of four different drums is needed. The invention concludes the realization that the preferred as a transfer drum trained transfer conveyor not necessarily complete with items must be occupied. Rather, the items can be at any Transfer conveyor only at certain points on the transfer conveyor be stored while other jobs remain free. In this way can the vacancies of the transfer conveyor to take back used by the processing drum machined article become.

By editing articles here is an effect on the Appearance, structure or function of the article, in particular a cutting, a perforation, a rewinding of the article with a paper tiling or printing on the article.

In an advantageous embodiment of the invention, the article on the processing drum between a pickup position at the the processing drum the articles from the transfer conveyor decreases, and a delivery position at which the processing drum the Returns items to the transfer conveyor on the Processing drum promoted by at least about 360 °. To this Way, the processed article returns to the transfer conveyor and can be placed on a free position on the transfer conveyor become.

For this purpose, the machining drum is preferably at least about 360 ° plus a circumferential length of the article rotates. In this way in a further preferred embodiment of the invention, preferably in an appropriately designed receptacle for the articles, the article on the peripheral surface of the processing drum rolled back. This preferably at least about 360 ° to its own axis running rolls of articles makes it possible For example, the articles on the processing drum on their to perforate the entire circumference.

To roll the articles in the recordings on the processing drum For example, one of the processing drum assigned Roller block be used. The roller block, whose axis of rotation is preferably parallel to the axis of rotation of the processing drum and its smallest distance to the processing drum preferred is slightly smaller than the diameter of the article, is preferably one Assigned to the laser assembly, the article by an appropriate Recess in the roller block and / or past the roller block during the Rolling of the articles perforated by the roller block.

An embodiment of the invention points to the transfer conveyor an even number of in the conveying direction at a certain distance to each other arranged shots for the articles on and on the Processing drum also an even number of Editing recordings for the article. Here are the Processing recordings on the processing drum so designed that in them items from the roll block around a odd multiple of, preferably measured in the conveying direction at least one-third of the size of the article amount, distance the recordings on the transfer conveyor are rollable. In this way can the rolled and possibly perforated articles after rolling in cover an unoccupied intake of the transfer conveyor and from For example, pass this on to a secondary drum.

The articles are preferred by the processing drum of the Transfer conveyor at a distance from each other in the conveying direction which is greater than or equal to the size of the article. On This way, the articles on the processing drum can be done easily rolled at least about 360 ° around its own axis and possibly on their entire circumference to be perforated during rotation. For this the articles on the transfer conveyor are preferred for Provided that they have a distance from each other, the preferably greater than or equal to four-thirds of the size of the article divided by the number of processing drums.

Another important advantage of the invention is that the Transfer conveyor several processing drums are assigned can. For example, with an even number of Recordings on the transfer conveyor in every second shot the transfer conveyor an article are provided, wherein the articles alternately to two juxtaposed identical machining drums are delivered.

If, for example, only one processing drum is available, then be - at a preferred distance of the recordings of at least one third of its circumference - on the transfer conveyor For example, only every fourth recording item available so that it is guaranteed by a certain Processing drum to be machined from the article Transfer conveyor in any case a distance in the conveying direction to each other, which is greater than or equal to the size of the article is, preferably four-thirds of the circumference, then advantageous to these articles on the processing drum at least the circumference of the article in the appropriate editing recordings, for example for Perforation of the articles to be able to roll.

The processing drum is in a manner known in the art and Assigned to the transfer conveyor and in particular with respect their extent and their rotational speed are formed and the transfer conveyor adapted to the articles of the Transfer conveyor in a desired manner according to the invention and Way can take over. For this purpose, the transfer conveyor is preferred Also designed as a drum, which is preferred as recordings for the Article to the conveying direction laterally extending, preferably in one Distance of at least one third of the scope of the article in Having conveying direction spaced troughs.

The processing of the articles according to the above However, embodiments are not limited to perforating the articles limited. Rather, it is with the above-explained Embodiments also possible, the articles during their Stay on the processing drum with a cover sheet too rewinding. It is possible, the supply of padding leaves and the Rewinding the articles with the cover sheets on the Machining drum to perform or more drums provide, which in turn are connected to the processing drum.

Exactly as in the above example with respect to the perforation the article listed embodiments of the invention is also in to record the scrolling of the articles as one of the advantages of the invention, that by the machining drum according to the invention the respective Processing removed from the actual production chain can be. The processing, e.g. Perforation or rollover with Plaque, can thus as a so-called stitch method to each Production chain to be connected. Because the articles will be for example, according to the above outlined preferred Embodiments the material flow or the production chain with Help taken from the processing drum, then for example perforated or rolled over with covering sheets, and finally from the same processing drum back into the production process placed therein.

Particularly advantageous in the example as explained above a drum branch branched drum branch is that by a such branching the error rate of the overall system considerably is reduced. Because in the case of an error in the Drum branch, it is sufficient to turn off the drum branch and to fix the error without the need to Main branch from drums to stop.

Applied to the rolling over of a tobacco rod filter tobacco rod group with a tipping paper thus finds the separation of Transport chain and the functional units delivering this rewinder prefers a removal of the actual rolling process from the Transport chain of the corresponding Filteransetzmaschine instead. For this purpose, the article components are preferred Tobacco sticks, double filters and tipping paper until rolling transported. The actual rolling process then takes place on one Drum branch branched off from the production chain. Similar to in the perforation of articles by rolling the tobacco rod filter tobacco rod group not just rolled over with the toppings, but also by a certain amount against the conveying direction set back on the drum circumference. In this way, the finished with tiling rolled over the same double filter cigarettes Drums of the branched drum branch of the actual Transport chain of the filter attachment machine to be fed again.

The drum branch is not on a processing drum limited. Rather, it is possible to have any number of To use machining drums in such a drum branch.

Moreover, in further preferred embodiments as well possible, the articles from the transfer conveyor on at least one Intermediate conveyor to the at least one processing drum to and then submit the articles after editing as well again about the at least one intermediate conveyor of the To return the processing drum to the transfer conveyor. By With the help of such intermediate conveyor can be in some Machines of the tobacco processing industry advantageous distance between the central production and material flow chain and the one or more processing drums of such Drum branch are created.

In further preferred embodiments of the invention the aforementioned intermediate conveyors are also used to Parts of the desired article are fed to them. That's the way it is For example, the attachment of the tipping paper leaflet to the Articles while articles on such Intermediate conveyors are located. Of course, it is also possible the covering paper sheets to the articles during the stay of the Article on the transfer conveyor or processing drum make. Finally, it is also possible to use the intermediate conveyors as form pure intermediate conveyor, i. during the stay of the Items on the intermediate conveyors to deliver any items and also not exceeding the actual promotion of the article Take action with the articles.

The invention further comprises a method for processing rod-shaped articles of the tobacco processing industry, with the Steps: The items are available on a transfer conveyor The items are delivered from the transfer conveyor to at least to hand over a processing conveyor for processing the articles that Articles are made during processing by the conveyor edited promotion, characterized in that the Article after processing from the processing conveyor again be returned to the transfer conveyor.

The invention also includes an apparatus for processing rod-shaped articles of the tobacco processing industry, with a Transfer conveyor for picking up the articles and with at least one the transfer conveyor associated processing conveyor for Picking up the items from the transfer conveyor and editing the article during a through the processing conveyor taking place Promotion of the article, characterized in that the Machining conveyor designed in such a way and the transfer conveyor It is associated with the articles after processing of the Processing conveyors are deliverable to the transfer conveyor.

In a preferred embodiment of the above device this is further developed such that the processing conveyor from a two rolling tapes formed rolling channel, one of the articles of the Transfer conveyor accepting and donating to the rolling channel first conveyor drum, one of the articles of the rolling channel decreasing second conveyor drum, and one the articles of the second Conveyor drum decreasing and to the first conveyor drum having dispensing third conveyor drum, wherein the articles with the aid of Roll channels the articles are offset upstream so that they from the third conveyor drum in unoccupied recordings of the first Conveyor drum are settable, so that they from the first conveyor drum of the processing conveyor directly into unoccupied shots of the Transfer conveyor or at least one intermediate conveyor in unoccupied recordings of the transfer conveyor can be returned.

A fifth embodiment of a device according to the invention.

FIG. 1 shows a first embodiment 1 of a device according to the invention Device for processing cigarettes 2.

The device 1 has a feed drum 4 designed as a Feeding conveyor for feeding the articles on. The feed drum 4 rotates according to arrow 6 about an axis of rotation 8 in the counterclockwise direction and promotes the article 2 in not shown, laterally to the conveying direction of Feed drum 4 formed in the peripheral surface 10 wells.

The wells have in the conveying direction at a distance from each other, the at least twice the diameter of Article 2.

Adjacent to the feed drum 4 is a transfer conveyor Serving transfer drum 12 is arranged. The transfer drum 12 rotates about a parallel to the axis of rotation 8 of the feed drum. 4 arranged rotational axis 14 according to arrow 16 in the clockwise direction the same peripheral speed as the feed drum 4. The Distance of the rotation axes 8 and 14 is dimensioned such that a smooth handover of Article 2 is ensured.

The transfer drum 12 has as recordings for the article 2 also formed laterally to the conveying direction in its peripheral surface 18 Hollows 20 up. The troughs 20 are in the conveying direction at a distance arranged on each other on the transfer drum 12, the half Distance of the wells on the feed drum 4 corresponds.

Adjacent to the transfer drum 12 is a first Processing drum 22 is arranged. The processing drum 22 rotates according to arrow 24 about a rotation axis 26. The axis of rotation 26 is parallel to the axis of rotation 14 of the transfer drum 12. Der Distance between the axes of rotation 26 and 14 is such that a easy handover of the article is guaranteed.

In the peripheral surface 28 of the processing drum 22 are in Conveying direction extended troughs 30 for receiving the article 2 intended. The troughs 30 are through laterally to the conveying direction trained webs 32 limited. The distance of the webs 32 corresponds four times the distance of the troughs 20 on the transfer drum 12. The extent of the wells 30 is such that the articles 2 in the hollows 30 can be offset (rolled) by a distance, the three times the distance of the troughs 20 on the transfer drum 12 corresponds.

The first processing drum 22 is a roller block 34 with a Rolloberfläche 36 assigned. The roller block 34 rotates with the same Circumferential speed as the processing drum 22 to a parallel to the axis of rotation 26 of the machining drum 22 arranged rotation axis in the counterclockwise direction. By corresponding recesses in the roller block 34 and / or on the Rolling block over a laser 38 radiates one to the perforation of the article 2 serving laser beam 40 perpendicular to the peripheral surface 28 of the Processing drum 22 from. The laser beam 40 is using a Focusing lens 42 on the peripheral surfaces 44 of the article 2 bundled. In this case, the articles 2 by rolling between the Processing drum 22 and the roller block 34 opposite to Direction of rotation of the processing drum 22 offset.

Downstream is adjacent to the transfer drum 12 a second Processing drum 52 is arranged. The second processing drum 52 is identical to the first processing drum 22. Same Parts are designated by reference numerals opposite to the Reference numerals of the first processing drum 22 and their assigned parts roll block 34 and laser 38, however, by the number 30th are increased.

FIG. 2 shows a second embodiment 90 of an inventive device Contraption. The device 90 corresponds identically to the device 1 with the only difference being that not two lasers 38 and 68, but only one laser 92 is provided, the light of which with the help of a not split beam splitter is divided into the laser beams 40 and 70, respectively.

Further downstream of the transfer drum 12 is a discharge drum 80th assigned. The removal drum 80 rotates counter to arrow 82 clockwise about a rotation axis 84. The rotation axis 84 is parallel to the axis of rotation 14 of the transfer drum 12. Die Abfördertrommel 80 corresponds to the feed drum 4. Just like the Feed drum 4 is also the discharge drum 80 adjacent to such the transfer drum 12 arranged that a trouble-free transfer Article 2 is guaranteed.

With the device 1 according to an embodiment of the Process according to the invention, processing of the articles 2 happens as follows:

On the feed drum 4 are laterally in the conveying direction arranged troughs Article 2 seen in the conveying direction in one Distance to each other, at least twice their Diameter corresponds. At this distance the articles 2 of the feed drum 4 passed to the transfer drum 12. Because the Transfer drum 12, however, relative to the feed drum 4 the half trough distance is on the transfer drum 12 only in every second trough 20 an article 2 provided.

The transfer drum 12 further promotes the article 2 in the conveying direction 16 to the first processing drum 22. The first processing drum 22 only removes every second article 2 from the transfer drum 12, because the troughs 30 of the first processing drum 22 in the conveying direction Seen 24 have a distance from each other, four times the trough spacing on the transfer drum 12 corresponds.

Once the article 2 is in contact with the peripheral surface 36 of the Rollklotzes 34 advised, the Article 2 in the conveying direction 24 seen backwards in the troughs 30 to the bridge behind them 32 rolled. Articles 2 will be completely transposed at least once its axis rotates while at the triple of the trough distance the transfer drum 12 is placed in the wells 30. At the same time with This rolling the article 2 on its peripheral surface 44 with the preferably pulsed laser beam 40 perforated, so that a complete perforation of the peripheral surface 44 of Article 2 during the backward rolling of the article 2 in the troughs 30 of Processing drum 22 takes place.

The thus perforated article 2, which in Figure 1 lighter than the unperforated article 2 are then represented by the Processing drum 22 as long along the direction of rotation 24, until they have lost more than one takeover position 31 360 ° were promoted around the axis of rotation 26 so that they in a Abgabeposition 33 arrive. In the example shown are the Positions 31 and 33 are identical. The perforated articles 2 are thereby opposite the troughs 20 of the transfer drum 12, from which the Processing drum 22 has the article 2 removed to three troughs set back.

The perforated article 2 is then removed from position 33 using the Transfer drum 12 removed from the processing drum 22 and in the conveying direction 16 of the transfer drum 12 further toward promoted the second processing drum 52. However, this takes the already perforated article 2 does not depend on the transfer drum 12, so that this is further promoted by the transfer drum 12 and finally arrives at the discharge drum 80, which is identical to the Feed drum 4 and the perforated article 2 of the Transfer drum 12 decreases and dissipates.

At the same time, they do not pass from the first processing drum 22 from the transfer drum 12 removed Article 2 to the second Processing drum 52, as indicated by the dark hatched article 2 in Figure 1 downstream of the first processing drum 22 on the Transfer drum 12 indicated.

The second processing drum 52 takes the perforating in the Figure 1 dark hatched Article 2 in an identical manner from the Transfer drum 12 from, as in the first processing drum 22 happens. Also the subsequent roll and perforation of the Article 2 fully complies with the above with reference to the first Processing drum 22 described procedure. same for also for the return of the perforated articles to the transfer drum 12 and the subsequent removal of the perforated article through the removal drum 80th

FIG. 3 shows a third embodiment 100 of a device according to the invention Contraption. The device parts shown in FIG Device 100 does not differ from the corresponding ones Device parts of the device 1 of Figure 1. They are therefore with the the same reference numerals. Only in the way it works The device 100 differs from the device 1 as follows:

From the feed drum 4 are only in every second position Article 2 supplied to the transfer drum 12. Thus be on the Transfer drum 12 only on every fourth trough 20 Article 2 to Provided. It is therefore sufficient, the first Processing drum 22 for rolling and perforation of the article 2 too use. On the second processing drum 52 may in the Embodiment 100 of Figure 3 are omitted. The second Processing drum 52 is therefore omitted in FIG. The Embodiment 100 therefore illustrates one of the crucial Advantages of the present invention. Because the invention can be flexible to an increase or decrease in the throughput of a Cigarette making machine react. Depending on the number of with the feed drum 4 fed Article 2, the second Machining drum 52 may be provided or omitted.

In addition, according to an embodiment not shown The invention also omits the first processing drum 22 if no perforation of the article is desired. The articles are then simply unchanged with the transfer drum 12 of the Feeding drum 4 conveyed to the discharge drum 80. This too is one decisive advantage over the prior art. Because in the The state of the art would also have to waive a perforation of Article a promotion of the article about all the drums that normally the roll or perforation serve to be made. hereby In the prior art, there is a large amount of time and loss of throughput and an increased space requirement while in the present invention can be dispensed with any machining drum that does not need becomes.

Figure 4 shows a schematic representation of a fourth Embodiment 104 of a device according to the invention for Processing cigarettes (not shown in FIG. 4). With help Figure 4 is intended above all the principle of the invention Branch of machining operations are clarified. To this purpose is in the middle of Figure 4 in a horizontal position 106th a production chain of drums one not shown Filter attachment shown. From this drum chain branch in of Figure 4 substantially vertically down two Processing branches 108 and 110 for processing cigarettes. The corresponding filters are turned over substantially vertically top branching Filterzuführzweige 112 and 114 supplied. by virtue of According to the invention, it is possible to have each of the branches 108, 110, 112 and 114 arbitrarily add or omit or turn on or off. Because by switching on or off or adding or omitting one of the branches 108, 110, 112 and 114 remains the actual one Material chain 106 unaffected.

In the device 104 shown in Figure 4 serve the Branches 108 and 110 of the enclosure of tobacco rod filter tobacco rod groups with tiling paper. Thereby the filters, which are in the Branching 108 are supplied, fed from the branch 112, while the filters wrapped in the branch 110 in the Branch 114 are supplied.

The drums in the device 104 are in the Filter attachment machines usual way driven, trained and coordinated.

Around the two branches 108 and 110 with tobacco rod filter tobacco rod groups to supply them, these are the production chain 106 in the device 104 via a respective supply branch 116 or 118 supplied. The branch 116 serves the branch 108 while the Branch 118 supplies branch 110. Of course you can be reversed. So can one of the branches 116 or 118 are omitted or switched off one of these branches without bringing the device 104 to a standstill. The Branches 116 and 118 may thus be the same as branches 108 and 110 operated completely independently or switched on and off become.

Likewise, it is possible to not filter over branches 112 and 114 but at any other place in the Device 104 to feed the tobacco double sticks, as long as it is before the wrapping is done by the tipping paper.

To the construction of the device 104 in detail:

The core of the material-carrying drum chain 106 is characterized by in essentially linear successively arranged drums 120, 122, 124, 126, 128, 130, 132, 134 and 136 are formed. The material flow in the Figure 4 goes from the drum 120 to the drum 136. As indicated by arrow 138, the finished double filter cigarettes are finally at the end of Device 104 in a usual in Filteransetzmaschinen type and Sent from a non-illustrated drum, one of not shown cutting device cut into individual cigarettes, but not shown, e.g. as shown in Fig. 3 executed Perforation perforated by a non-illustrated Spreading drum spread in single cigarettes, using a non-illustrated Test device subjected to a head test and also in the rest in the filter attachment machines or machines tobacco-processing industry usual, but not shown kind and further processed.

The first drum 120 of the chain 106 become tobacco double sticks from both feed branch 116 and feed branch 118 fed. The branch 116 takes over for this purpose with the help of a Drum 140 tobacco double sticks from a single or a Two-lane cigarette machine and gives this to a drum 142 further. As shown purely schematically in FIG. 4, it does not shown double stick then on the drum 142 by means of a Cutting device 144 cut and then cut in shape passed a spreading drum 146. On the spreading drum 146 are the individual sticks of tobacco double stick lateral to Movement direction away from each other to move between them later course to be able to place the double filter.

In the same way are also not shown Tobacco double sticks in the branch 118 of drums 140a, 142a, 146a and a cutter 144 a of the drum 120 is supplied.

On the drum 120 are thus two families of cut and spread tobacco double sticks. A family is from the feed drum 140, while the other of the Feed drum 140a comes. The drum 120 must therefore with appropriate recordings to be from the feed drums 146 and 146a to be able to record all double sticks. These will then passed from the drum 120 to the drum 122. The Drum 122 serves as a distributor drum. Because it will be from the Drum 122 in the device 104 shown in the figure 4 the from the feed drum 140 derived double sticks in the branch 108, while that of the feed drum 140a coming double sticks to those in the chain 106 subsequent Drum 124 are forwarded to continue in the branch 110 to be processed.

The drum 124 is not only used in the illustrated embodiment the forwarding of the double sticks of the feed drum 140a, but also the introduction of double filters, the drum 124 of a Filter feed drum 148 of the filter feed branch 112 takes over. The Filter feed drum 148 receives the filter of not shown further Filter feed drums which turn the filters from a non-illustrated, obtained as usual filter production.

The drum 124 carries the double filters of the drum 122 in a manner to that they double filter between that of the feed drum 140th obtained double sticks come to rest. The drum 122 leads then the tobacco rod filter tobacco rod groups into branch 108.

The branch 108 has for this purpose a first intermediate conveyor drum 150 for Removing the groups from the drum 122 and a second one Intermediate conveyor drum 152 for removing the groups of the Drum 150 up. The drum 152 serves that of the drum 150 tobacco rod filter tobacco rod groups obtained from one endless tipping paper strip 154 by means of a cutting drum 156 cut off cover sheets with the help of a Adhere padding applicator drum 158. That way with Tapered Tobacco Stick Filter Tobacco Stick Groups are then from the drum 152 to the inventive Processing drum 160 delivered. On the drum 160 are the Tobacco stick filter tobacco stick groups with the sticking to them Tufing paper is rolled over with the aid of a roller block 162. Through this roll then the finished double cigarette is counter to the conveying direction placed back in a designated free recess of the drum 160.

In this way, the drum 160 according to the invention is capable of finished articles in appropriate designated free hollows the Drum 152 store, which in turn the finished article in turn provided for this purpose free troughs of the drum 150 stores, in turn again the articles in designated free hollows of the drum 122 stores.

From the drum 122, the finished double cigarettes are then to the provided for further transport drum 124 delivered.

The drum 124 then outputs that from the feed conveyor drum 140a obtained double sticks and those of the processing drum 160th obtained finished double filter cigarettes to a Intermediate conveyor drum 126 and this in turn to a Intermediate conveyor drum 128 and this in turn to the drum 130th further.

The drum 130 has the same function as the drum 122. The means that the drum 130 obtained from the drum 160 finished double filter cigarettes to a discharge drum 132 emits the the finished double filter cigarettes to a intermediate conveyor drum 134th and this in turn emits to a intermediate conveyor drum 136, the then emits this according to arrow 138 for further processing.

At the same time, however, the drum 130 is replaced by that in the drum 122 described manner on the drum 132 of a Filter feed drum 161 of the branch 114 filters for the spread Double tobacco rods of the feed drum 140a. Subsequently, the thus filtered tobacco rod filter tobacco rod groups of the drum 130 in the manner described with respect to the drum 122 Way to a intermediate conveyor drum 150a, from there to a second intermediate conveyor drum 152a, on the second Intermediate feed drum 152a by means of one of an endless Tipping paper strip 154a from a designated cutting drum 156a trimmed covering sheets, which from a Plaque applicator barrel 158a on tobacco rod filter tobacco rod groups is attached, provided with pads and finally, with these cover sheets on an inventive Machining drum 160a with the aid of an endless roller block 162a rolled over. Likewise, the return of the finished happens Doppelfilterzigaretten to the drum 130 as in relation to the Branch 108 also described in this speech standing branch 110.

FIG. 5 shows a section of the device 104 of FIG. 4 in FIG enlarged view. In FIG. 5, the branch 108 is in particular the device 104 together with in the vicinity of the branch 108 arranged drums shown enlarged.

FIG. 5 serves to illustrate the passage of branch 116 resulting double sticks 166 compared with from the branch 118th resulting double sticks 168. In Figure 5, the double sticks 166 shown as hollow circles with a horizontal diagonal, while the double sticks 168 as hollow circles with an oblique Diagonals are shown to the double sticks 166 of the Double sticks 168 to distinguish.

In the embodiment shown in Figure 5, the drum 146 carries only in every third trough a double stick 166. Likewise carries the Drum 146a only in every third trough a double decker 168. Both in the drums 146 and 146a as well as in the others in Figure 5 Drums shown are the directions of rotation of the drums symbolized by curved arrows attached in the drums. The Drums 146 and 146a track their double sticks 166 and 168, respectively the succession of these drums spreading on the provided with corresponding troughs downstream feed drum 120 off. The feed drum 120 then delivers both tobacco double sticks 166 and 168 to the drum 122.
