Groups of filter segments or groups of filter rods are formed and then the strand forming device are transferred such that the groups of filter rods can be wrapped longitudinally with wrapping material. The group-forming device is a device which is completely exchangeable in the event of a change in the filter segments or the order of the filter segments.

This involves a great financial outlay and a low variability in the production of multifilaments.

Applicant's typical stranding device is called KDF 2E. A typical Anmeiderin group picture device is called GC E. Both devices are known to the public and are marketed together as a MULFI E machine.

To transfer the groups formed by the group forming device to the rod forming device is on the DE-OS 25 34 666 , the the US 404 46 59 corresponds, pointed out.

From the DE 198 58 600 A1 the Applicant is also a device for longitudinal axial positioning to be severed rod-shaped articles of the tobacco processing industry is known, in particular finds a hollow drum application is formed by the staggered successive filter rods to a transverse axial series formation for the purpose of performing a separation cut through the filter rods.

It is the object of the present invention to develop a multi-segment filter production device with an aforementioned device for assembling groups of filter segments for the production of multi-segment filters in such a way that variability in the multifilament production is made possible. The corresponding device should also be inexpensive and in particular with regard to the variability of the production of different multifilters. Furthermore, in the case of a conversion of the device for producing a multifilter of another type, the greatest possible time saving should be provided. Schlammlich it is object of the present invention to provide a way by means of which the means for assembling groups of filter segments for the production of multi-segment filters can be designed to save space, and further the corresponding operations that can be carried out with such facilities can be realized on a shortened conveying path should.

This problem is solved by a multi-segment filter production device according to claim 1.

By the divisibility of the means for assembling groups of filter segments. According to claim 4, the conveying elements in a plurality of independent Funktionsseinhalten is given a maximum variability in the Multifilterherstellung wöbei in the desire to produce different multifilters, a quick and cost-effective adjustment is possible in which possibly the self-service units are only rearranged and adapted or, for example, only a few modules or functional units must be purchased. In the context of this invention, the term "functional units" also includes the term "module". In the context of this application, the term divisibility of the functional units means, in particular, that the functional units are composed.

If a functional unit is provided for each type of filter segment of a multi-segment filter, a particularly space-saving device can be implemented. If per filter segment of a multi-segment filter, in particular a single, functional unit is provided, a particular high variability of the device is possible. According to the invention, a particularly simple combination of groups of filter segments is possible when the plurality of independent functional units are arranged in a row dergestelt that at least a part of the conveying elements of two adjacent functional units come into operative connection with each other, in particular are tangible. The filter segments are meander-shaped transported by the conveying elements, wherein in the region of the operative connection, the filter segments are transferred from a conveying element to an adjacent conveying element. On these conveyor elements filter segments can then be assembled in a particularly simple manner. Since according to the invention transfer drums. Filter segments or filter segment groups transferring conveying elements are arranged horizontally in a row, a simple embodiment of the device is given. According to the invention, each functional unit comprises at least one assembly drum. The group of filter segments by means of the conveying elements transverse axial conveyed, so that the device and the independent Funktionselnheiten can be designed according to compact design.

Preferably, a hollow drum for Lingsaxialen positioning of severing and / or severed rod-shaped articles of the tobacco processing industry in receiving troughs; provided with movable, in particular in the receiving troughs extending alignment stops, provided wherein at least one positioning means for positioning away from each other in a receiving trough longitudinal axial hub arranged rod-shaped article of the tobacco-processing industry are provided. The inventive design of a hollow drum, it is possible to provide more functions on a conveyor drum, so that the total number of a functional unit according to the invention can be reduced, whereby corresponding independent functional units or devices for assembling groups of filter segments for the production of multi-segment filters of the tobacco processing industry very plaltsparend can be built. In addition, if a drum means associated with the cutting means is provided, it is possible to save more drums. Preferably, when the one positioning means for positioning away from each other comprises at least one suction air passage, it is possible to move the rod-shaped articles through activated suction channels in a gentle, quick and easy manner. If at least two suction air ducts are provided which are arranged longitudinally axially at opposite ends of the receiving trough, it is possible to move away two longitudinally juxtaposed rod-shaped articles from each other in a particularly simple manner. If vorzugswelse a ventilation opening is provided in a trough seal, the movement of the two rod-shaped article longitudinally away from each other away faster possible. The ventilation opening is preferably arranged in the trough seal such that a ventilation between two longitudinally adjacent axially arranged bar-shaped Antikeln is possible.

If means are preferably provided for transferring the articles received and staggered in the transverse axial successive receiving troughs into a transverse axial aligned position in which preferably a cutting operation can be carried out, in particular three working steps are possible with the trough drum, namely transverse axial alignment of the transverse axial in succession Receptacles received and staggered items, cutting the items and moving away from each other the cut items. This hollow drum can therefore be referred to as a sliding / cutting / sliding drum.

In order to achieve a Schneidausrichung quickly and on the shortest possible conveying path, it is also proposed that the one end face of the article acting on the alignment stops are longitudinally displaceable relative to the receiving wells. In this way, the previously unilaterally applied filter rod components or rod-shaped articles during their separation an alternative possibility is given.

In order to match the successive aligning and evasive movements of the alignment exactly to one another, is provided according to a development that the alignment stops these vorbewegenden outside of the effective range of the form of a circular blade cutting means in a defined stop position and in the effective range of the cutting means from the stop position retracting actuator means are provided. Conveniently, the actuator means are designed as a front end with the trough drum rotating Taumelschelben.

In order to assure a defined longitudinal axial and transverse axial alignment of the articles or the article row relative to the cutting means by simple means, it is furthermore provided that the alignment stops are provided in the region of their stop face with a recess covering the trough base of the receiving troughs in their roofing area with the alignment stops open co-operating suction channels. A secure suction is ensured by an additional proposal, characterized in that the suction channels can be activated in an alignment zone defined by a circumferential coverage of the trough drum.

In order to enable or select a need-based positioning of the article, in particular in cooperation of the sliding / cutting / sliding drum with successor drum, weiterhln is proposed that the dipping into the receiving troughs registration stops arranged with their Stellantriesbsmitteln on at least one end face of the trough drum are or alternatively arranged on both end sides of the drum tub.

The advantage is that three normally obstructing operations can be vorgenormmen on a single conveyor drum, which can account for three drum. As a result, the size or overall height of the machine unit, ie the functional units and the device for assembling groups of filter segments for the production of multi-segment filters and finally also the multi-segment filter manufacturing device, is reduced as a whole by vertical and horizontal center distances of the conveyor drums.

Finally, it is a separate functional unit, in particular for feeding filter segments to further filter segments, by means of which groups of filter segments for producing multi-segment filters of the tobacco processing industry can be assembled into a continuous process, wherein the functional unit comprises at least one well drum as described above.

A particularly preferred embodiment is provided when the device for putting together groups of filter segments for the production of multi-segment filters of the tobacco-processing industry is provided in a continuous process with at least one well drum of the type described above.

In the following description of the figures, parts that are the same are denoted by the same reference numerals, so that they are left out of consideration.

In the Fig.1 shown Multisegmentfilterherstelleinrichtung gem. The prior art is constructed as follows:

The strand forming device 1 is associated with a cross-acting group forming device 2, which has two reservoirs 3 and 4, in which filter rods 6 and 7 of a first and second types are located. At the lower, auslaβseitigen ends of the reservoir 3 and 4 are removal drums 8 and 9, each of which a cutting device 11 and 12 is assigned, which cut the removed from the reservoirs 3 and 4 filter rods 6 and 7 respectively. This is followed in each case by a staggering drum 13 or 14, on which the filter sections formed from the severed filter rods 6 and 7 are brought into a staggered formation and subsequently displaced by a respective sliding drum 16 or 17 such that they form a row in transverse axial succession. The thus formed rows of filter sections are anschreißend pulled apart by a respective accelerator drum 18 and 19, so that there are larger distances between the individual filter sections.

Thereafter, the filter sections on cutting drums 21 and 22, which also each have a cutting device 23 or 24 associated, again severed. The again cut through filter sections are at the same time again pulled apart on the cutting drums 21 and 22, so that larger gaps between the individual elements. In each case, elements of filter rods of the respective other type are inserted into these gaps on a compilation drum 26 and in this way filter rod groups 27 are formed, which are composed of several elements of the different types of filter .: The filter rod groups 27 are then replaced by a dispensing means in the form of a transfer device Turning drum 28 aligned longitudinally to the conveying direction and passed continuously in a continuous formation on a withdrawn from a reel 29 wrapping strip 31 of the strand forming device 1. The transfer happens eg according to the DE-OS 25 34 666 ,

Before depositing the filter rod groups 27 on the wrapping strip 31 this is glued. For this purpose, a first gluing device 32, indicated by a glue reservoir 33 and two applicator nozzles 34 and 36 is provided, which applies a innenbelehmung in the form of two juxtaposed, parallel glue strips on the wrapping strip 31. A second gluing device 37, indicated by a glue reservoir 38 and a glue application nozzle 39, provides the wrapping strip 31 in the region of an edge with a glued strip for seam gluing. It goes without saying that if necessary, only one glue strip or even more than two glue strips can be provided for the internal gluing.

Bel an application, acc. the glue reservoir 33 of the first glueing device 32 contains a cold glue and the reservoir 38 of the second glueing device 37 contains a hot melt glue is in the depositing area 41 of the turning drum 28 below the wrapping strip 31 a means 42 for setting the internal gluing in the form of a heating device 43 is provided, which ensures that the applied by the glue application nozzles 34 and 36 internal glueing sets immediately after the filing of the filter rod groups 27 and the filter rod groups 27 in this way immediately after depositing on the Envelope strips 31 are fixed so that they can no longer be lost by external influences, such as by subsequent filter rod groups.

At the same time, the helm device 43 activates the hot melt adhesive for the seam sizing. The fitter rod assemblies 27 thus fixed in a continuous row pass thereafter through a molding in the form of a format chamber 44 in which the wrapping strip 31 is wrapped around the filter rod assemblies 27 to form a continuous filter strand with the hot melt adhesive applied through the glue applicator nozzle 39 the seam gluing is tied off within an adhesive chamber 46, which is designed as a cooling device 47 for this purpose. The thus sealed and sealed filter string also connects to a cutter 48 in which combination filter rods 49 of preferably multiple use length are cut, each containing filter elements of the different types of filter rods 8 and 7.

A multisegment filter production device according to the invention with a device for assembling groups of filter segments for the production of multi-segment filters is disclosed in US Pat Fig. 2 shown. The strand forming device 1 essentially corresponds to the strand forming device 1 of Fig. 1 , being in Fig. 2 nor a strand cutter 50 is indicated, by means of which at the beginning of the strand formation at the moment a cutting off of the filter strand can take place by the wrapping of the filter segments with wrapping material proceeds successfully and properly. The cut filter rod then lands on a chute in a refuse container 56. It is also in the strand forming device 1 still a push-in drum 57 is shown, by means of the filter n-times use length, such as. 2-, 4- or 6-fold use length to another Processing, in particular for assembly with tobacco rods are pushed into another machine by means of the insertion drum 57.

In Fig. 2 Also shown is the means for assembling groups of filter segments to make multi-segment filters. This is also a group-forming device 2, although in each case independent functional units 604, 605.1, 605.2 and 61.1 are used. The functional unit 604 is a soft element unit, by means of which two individual filter segments are supplied ( Fig. 4a ), the functional unit 605.1 and 605.2 is a soft element unit by means of which a single Filterstöpsei or a single filter segment double the use length is supplied, and the functional unit 61.1 to a hard element unit. Reservoirs 53.1-53.3 and 54.1 are respectively provided in the functional units, a soft element pre-storage container 53.1-53.3 being naturally provided in the soft-element unit 605.1, 605.2 or 604 and a hard-element storage container 54.1 in the hard-element unit 61.1. In the soft element units 604 and 605.1 and 605.2 which segments or soft elements, for example. From a cellulose acetate or a nonwoven, processed and deposited the processed segments on a drum, whereas in the hard element unit 61.1 hard segments, such as sintered granules, filled with granules sleeves or empty pods, to be positioned on a drum. The group-forming device 2 or the independent functional units are supplied with energy by means of a power supply unit 58.

By means of the Multisegmentfilterherstelleinrichtung gem. Fig. 2 For example, multi-segment filters for cigarettes can be produced which have four filter elements.

It is now, for example, a soft element double use length in the center of the corresponding trough 84 of the compilation drum 64.2 (see Fig . 5 a) arranged. Hard elements can then be arranged adjacent to this soft element of twice the useful length, whereupon by means of the functional unit 604 two soft elements are arranged outside around the arranged hard elements. Finally, by means of the functional unit 605.2 which is arranged closest to the transfer unit 82, another soft element of double use length is arranged on the left or right of the group of filter elements in the respective hollows of the transfer drum 63.6 or compilation drum 64.2 in a transverse axial alignment. The group of filter segments thus formed is then transferred to a transfer unit 62 and stored by means of the known turning drum 28 longitudinal axial on the conveyor of the strand imaging device 1, then by means of wrapping paper from a reel 29, the in Fig. 2 is not shown, however, which is mounted on a reel holder 30, to form a Multifilterstrang. For this purpose, a standard filter wrapping paperboard can be used.

The invention thus relates in particular to a new group-forming device 2 which, for example, can be combined with a KDF of the applicant to form a filter production line. Multiple filters can be produced, which are processed as 4- or 6-fold long filter rods in the filter attachment machine MAX of the applicant with tobacco sticks to filter cigarettes.

In Fig. 3 is a variation or another embodiment of the present invention compared to Fig. 2 shown. In Fig. 3 is located in the comparison between the two left soft element units 604 and 605.2 of Fig. 2 another hard element unit 61.2. There are so for example. Multiple filters for cigarettes produced, the five different segments include.

In Fig. 4a ) schematically shows a soft element unit 604 according to the invention, with which two individual filter segments are supplied. In a Weichelementvorrastsbehälter 53.1 which filter rods 80, such as. From cellulose acetate, introduced via a feed element 70.1 By means of a removal drum 8.1, the corresponding filter rods or filter elements 80, for example, an 8-fold use of use taken. For a secure decrease of the filter elements 80, the deflector roller 71.1 is provided. A device for removing rod-shaped articles from a supply is, for example, from DE 25 05 998 C2 , the the US 40 20 973 corresponds, known.

The filter elements 80 are then cut on the removal drum 8.1 by means of a first circular knife 72.1, which is operated in rotation and is constantly ground on a grinding element 73.1, into two filter elements 81 four times the length of use. Thereupon two further cuts are arranged by two further circular knives 72.2 one behind the other, of which in Fig. 4a ) only the front circular blade can be seen, carried out so that the filter elements 81 are cut into a total of four filter elements 82 twice the length of use.

There then takes place a transfer of the four filter elements 82, which are arranged on the removal drum 8.1 longitudinally, such as. In Fig. 4b ) is shown on a staggering drum 13.1, by means of which the filter elements 82 are staggered, as in Fig. 4b ) is also indicated. Next, a transfer takes place in a sliding / cutting drum 74.1, in which a first transverse axial alignment of the filter elements 82 is made to then cut them with the circular blade 72.3 in two filter plug 83. The filter plugs 83 cut in this way are transferred to a transfer drum 63.4, in order then to be transferred to a slide / transfer drum 75.1, in which the filter plugs 83 are pushed apart from one another. Finally, the pushed apart filter plug 83 are transferred to a compilation drum 64.1 and then to a transfer drum 63.5, which can be brought into operative connection with a compilation drum 64.2 - 64.5 another functional unit to the deposited on the transfer drum 63.5 filter elements with the on the other compilation drum 64.2 -. 64.5 deposited filter elements bring together.

Fig. 4c schematically shows a further embodiment according to the invention of a soft element unit 604, which in the main of the soft element unit Fig. 4a ), in which, however, some drums are designed differently Die in Fig. 4a ) drums 74.1 and 63.4 are replaced by a sliding / cutting / sliding drum 90.1. Further, the sliding transfer drum 75.1 is replaced by a transfer drum 63.11.

The slide / cut / slide drum 90.1 substantially corresponds to the slide / cut / slide drum 90 described below with reference to FIGS. 7 and 8. In the Fig. 4d ) shown filter elements 80 to 83 are up to the staggering drum 13.1 accordingly as in Fig. 4a ) processed. The staggering drum 13.1 stages filter elements 2 times the use length 82 and transfers them to the sliding / cutting / sliding drum 90.1. In this, the filter elements are 2 times the length of use initially aligned transversely axial then pulled apart and längsaxial pulled to then pass the appropriately cut filter plug 83 with a correspondingly provided distance in the longitudinal axial direction of the transfer drum 63.11, in turn, the filter plug in receiving cavities 84 of Compilation drum 64.1 transfers. If necessary, the transfer drum could be removed from this embodiment in the case of geometrically somewhat different arrangements, so that the overall height of the soft element unit 604 would be reduced.

In Fig. 5a A further exemplary embodiment of a functional unit 605.1 or 605.2 according to the invention is shown in a schematic representation. With this functional unit 605.1 or 605.2, a single filter plug of double the use length is supplied. The difference to the functional unit 604 Fig. 4a ) is that a staggering drum 13.3 is provided instead of the downstream first transfer drum 63.4, by means of which the cut filter plug 83 are staggered passed to the sliding / transfer drum 75.2, so that per well in the sliding / transfer drum 75.2 or per well in the assembly drum 64.2 and the transfer drum 63.6 assigned to this unit are arranged at most only one filter plug 83. In Fig. 5b) and Fig. 4b ) is also shown schematically the receiving trough 84 of the Zusemmenstelltrommel 64.1 and 64.2. With the function according to Fig. 5a Preferably, the first and the last filter segment of a multi-segment filter are inserted. In the case of the functional unit 605.2, however, all previously inserted filter plugs 83, 87 are already arranged on the assembly drum 64.2 and transfer drum 63.6 and the newly supplied filter plug 83 of double use length is applied to one side of the filter segment group.

In Fig. 6a ) is a hard element unit according to the invention 61.1 - 61.3 shown. From a hard element storage container 54.1 two removal drums 8.3 and 8.4 are fed via two feed shafts 88.1 and 88.2 hard filter elements 87. For this purpose, as is schematically shown in FIG Fig. 6a ), a mobility of the Zuführschächte 86.1 and 86.2 feasible to provide the smoothest possible transfer of the hard filter elements 87 in the removal drums 8.3 and 8.4. The removal drums 8.3 and 8.4 can also be designed accordingly to allow rapid transfer of many elements. For this purpose, in particular to the patent application of the applicant with the Title "Transfer device and drum drum and method for the transfer of cigarette components" referenced the official file number DE 101 48 992.6 Has.

The staggered as in Fig. 6b ), transferred hard filter elements 87 are then transferred into sliding drums 18.1 and 16.2, in which the hard filter elements 87 are arranged transversely in the successive receiving troughs. The cross-axially aligned hard filter elements are transferred via a transfer drum 63.8 to the assembly drum 84.3 of this unit and then transferred to the transfer drum 63.7.

In Fig. 7 is a schematic plan view of a portion of a soft element unit 604 or 605.1 - 605.6 shown, wherein in particular a central element of a soft element unit according to the invention 604 or 605.1 - 605.6 by the sliding / cutting / sliding drum 90 is shown. Corresponding filter elements 82, for example filter elements of twice the useful length, are staggered by a staggering drum 13.4 into the drum 90 at position a). In the direction of movement of the drum 90, the transferred filter elements 82 are then positioned transversely aligned in the receiving cavities 84. For this purpose, a trough seal 92.1 is provided, which prevents falling out of the filter elements 82 when, for example, a filter element holding the suction air is switched off to move the corresponding filter elements. This process happens in pos. B).

In item c), the respective filter element 82 is cut into two filter plugs 83 by means of a circular knife 72.7. The two filter plugs 83 are then moved away from each other in pos. D). For this purpose, again a part of the suction air, which holds the filter plug, turned off, so that even at this point a trough seal 92.2 is necessary. In item e), the filter plugs 83 are then transferred to the assembly drum 84.4 and, if necessary, assembled with further filter plugs or filter elements already thereon.

In Fig. 8 the operation of the sliding / cutting / sliding drum 90 is shown. In each case, the various elements a) to e) show the elements essential to the process. In Fig. 8a ), the staggered filter elements 82 are transferred into the receiving troughs 84. It then acts suction air from the left side on the filter elements 82 in Fig. 8b ), so that they move to the left to the left stop 93 and 93.2. Ansteile of the application of suction air could also find a sliding element 88 use that is not in Fig. 8 is shown, but, for example, in Fig. 9 , The filter elements 82 are now transversely aligned in the receiving cavities 84 before.

In the pos. C), the left stop 93.1 or 93.2 is a little moved away from the filter elements 82, to then perform a cut with a circular blade 72.7, so that filter plug 83 form.

In Pos. D) are moved away from each other by Saugluftbeaufschlagung between the elements, so that both filter plug 83 at the two stops 93.1 and 93.2 and 94.1 and 94.2, ie left and right, rest. In pos. E), the stops on the left and right are moved away a little from the filter plugs 83 so that they can be transferred freely into another drum.

In Fig. 9 are in the various positions a) to e) respectively schematic half-sectional views of the sliding / cutting / sliding drum 90 shown in Pos. a) are the filter plug 82 staggered behind each other before. The left filter element 82 is shown in section and the filter element 82 arranged on the right in a plan view. The filter elements 82 are held by suction air through air holes 108 and 107 in the receiving trough 84. The suction air is controlled by an air control body 98 depending on the rotational position of the drum 90. In this position, suction takes place through four air bores 108 and 107 via a cutout 100 to the air outlet 99. The direction of the suction air is indicated by arrows. The drum 90 moves over a while 102, which is supported by ball bearings 101 and a needle bearing 103. Further, a Taumelschelbe 97.1 and 97.2 is shown, on which the left and right stoppers 93.1 and 93.2 and 94.1 and 94.2 are mounted. The movement of the swash plate is controlled by a cam 109 which is supported by a torque arm 96.

In Pos. B), in which a schematic half-section through the drum 90 is shown, the filter elements 82 are shown arranged transaxially one behind the other. It is also schematically shown a sliding element 88, by means of which the filter element arranged behind the front filter element has been pushed with the front filter element in an aligned position. Instead of the schematically illustrated sliding element 88, it is also possible to provide a corresponding Verschlebung with suction, as in the Fig. 8b) otherwise indicated. In this case, the sliding element is not necessary. It is insofar an alternative embodiment, which is introduced for simplicity in a drawing together.

In pos. B) the Fig. 9 The filter elements 82 are acted upon from the left with suction over the leftmost air holes 106 and 107. As a result, the filter elements 82 move to the left stop 93.1. For this purpose, the remaining air bores 106 are closed by the air control body 98. So that the filter elements do not fall out of the troughs, a trough seal 92.1 is provided. This trough seal 92.1 has an opening 110 or cut-out 110 to the atmosphere on the right side, so that vacuuming on the right side does not occur when the filter elements are sucked to the left, which could prevent the filter elements from moving to the left.

In pos. C) of Fig. 9 the left stop is something has been moved to the left, so that a cut can be made by means of a circular knife 72.7, which engages in the Messemut 104, without squeezing the left-hand filter element. In this position, the filter elements 82 and the then cut filter plug 83 are held again by suction air accordingly.

In pos. D) of Fig. 9 the cut filter plugs 83 are moved away from each other. For this purpose, both the left side of the trough and the right side of the trough 84 is provided with suction air through the respective air holes 108 and 107. In order that no vacuum is formed between the filter plugs moving away from each other, an air bore 108 in the trough seal 92 Area of the right side of the left filter plug 83 is provided. Finally, in pos. E) the Fig. 9 First, the respective stops 93.1 or 93.2 and 94.1 or 94.2 moved away from the filter plugs 83 in order to then be able to transfer them to the assembly drum 64.4.

In particular filter plugs are aligned, cut and spread with the drum. This causes that, for example, the in Fig. 4a ) shown schematically, downstream drums 74.1, 63.4 and 75.1 can be replaced by a single drum 90, so that the functional unit according to the invention can be built very space-saving.

In Fig. 10a 1), a further embodiment of a soft element unit 605.3 is shown schematically, by means of which two single filter segments 83 are fed to a compilation drum 64.5. In a soft element storage tank 53.4, which filter rods 79, such as cellulose acetate, are introduced via a feed element 70.3. By means of a removal drum 8.5, the corresponding filter rods or filter elements 79 are removed, for example, a 16-fold use length. For a secure removal of the filter elements 79, the deflector roller 71.3 is provided.

The filter elements 79 are then sharpened on the removal drum 8.5 by means of a first circular knife 72.8 and two second circular knives 72.9, which are sharpened by abrasives 73.8 and 73.9, respectively. Cut into four filter elements 81 4 times the length of use. Thereafter, the cut filter elements 81 are transferred into a staggering drum 13.5, so that these as in Fig. 10b) is shown staggered on the staggering drum 13.5 are arranged. On the subsequent sliding / cutting drum 74.3, the initially staggered filter elements 81 are moved transversely aligned in axial direction in order then to be cut into two filter elements 82 2 times the length of use by means of another rotary knife 72.10 moving in rotation. These are then staggered to the staggering drum 13.4 passed. It then follows the sliding / cutting / sliding drum 90 according to the invention, by means of which the filter elements are 2 times the use length 82 cut into filter elements 1-fold use length 83 and pulled apart, to then be transferred to the assembly drum 64.5. Subsequent to the assembly drum 64.5, the transfer drum 63.9 is arranged, to which the filter elements 83 are transferred.

By using independent functional units in a device for assembling groups of filter segments for the production of multi-segment filters, it is possible, for example, to achieve an increase in production efficiency when using hard elements by using a plurality of modules. Furthermore, a high production capability is possible if only soft modules or soft element units are used. In particular, two to five filter segments can be produced per multi-segment filter. Corresponding granules are preferably used in hard elements.

The multisegment filter production device according to the invention requires a very low mechanical engineering effort. Furthermore, a low functional risk is given, since known methods are used in some processes, such as in particular the known strand method or, for example, the method DE-OS 2452 748 is described and used in the stranding machine KDF the applicant.
