In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

Fig. 1 shows a schematic side view of a formed as a covering device 1 for supplying a partially perforated tipping paper strip 2 in a schematically designated Filteransetzmaschine F. A filter attachment machine HAUNI Maschinenbau AG, Hamburg, is known under the name MAX. The device 1 will be described below with reference to the path of the tipping paper strip 2.

The tipping paper strip 2 is pulled off by a supply roll 4 rotating about an axis 5 in accordance with the indicated arrow direction by means of a take-off roller pair 6 and 8. One of the two take-off rolls, here the take-off roll 6, is driven by a drive 11 via a toothed belt 7.

Before the tipping paper strip 2 reaches the take-off rolls 6 and 8, it is conveyed via a deflection roller 12 to a breaker 14. The breaker 14 breaks the paper of the tipping paper strip 2 so that it can later be more easily wrapped around the filter-cigarette groups.

At a predetermined distance downstream of the pair of withdrawal rollers 6, 8 a gluing device 22 is provided for applying glue to the tipping paper strip 2. The gluing device 22 has a glue nozzle 24. The gluing can also be done with a roller gluing. With the help of the glue nozzle 24 glue images are applied to the tipping paper strip 2, which have glue-free zones that correspond to the perforated sections on the tipping paper strip 2, so that no glue is applied to the perforated sections.

Downstream of the gluing device 22, the tipping paper strip 2 passes via deflecting rollers 26, 28 and 29 to a lining cutting device 30 for the periodic separation of tipping paper sections from the tipping paper strip 2.

The pad cutting device 30 has a cutterhead 32 with knives 34, which are arranged at its circumference and slightly angled relative to the radial, and a counter-rotating cutting drum 36 which receives the padding paper strip 2.

The cutting drum 36 has groove-like recesses 38, in which the blades 34 due to the distance of the drums 32 and 36 to each other with rotation of the two drums 32 and 36 can dive to the on separating the periphery of the cutting drum 36 seated tipping paper strips 2 or strip of material formed therefrom. Below the bearing surfaces 40 provided on the periphery of the cutting drum 36, the cutting drum 36 has suction holes 42 connected to a suction device for holding the tipping paper strip 2 and the separated tipping paper leaflets 39 on the cutting drum 36.

Between the guide rollers 26 and 28, a standing with the tipping paper strip 2 oscillator 44 is arranged and synchronized with the drums 32 and 36 to slightly hold the tipping paper strip 2 after each cut by one of the blade 34 against the direction of movement 20 relative to the drum surface, so that a distance between the individual cut sections or covering paper leaflets 39 of the tipping paper strip 2 arises. The oscillator 44 thus converts the uniform supply of the tipping paper strip 2 to the gluing device 22 into a non-uniform supply to the pad cutting device 30. Further details of the pad cutting device 30 and of the oscillator 44 may be, for example DE-A-39 18 137 be removed.

Fig. 2 schematically shows in a fragmentary enlarged view of the pad cutting device 30. The tipping paper strip 2 or from the tipping paper strip 2 formed by longitudinal cutting material strips are conveyed to the cutting drum 36 which wraps the tipping paper strip 2 or its material webs relative to the cutterhead 32 in a predetermined angle section. The peripheral surface of the cutting drum 36 is acted upon in a conventional manner with suction air, which is supplied via Saugluftbohrungen 42 and 43 and the tipping paper strip 2 adheres to the surface of the cutting drum 36 and leads and is dimensioned so that a slip between the tipping paper strip 2 and the surface of the Cutting drum 36 is possible.

The cutting drum 36 has in its peripheral surface axially parallel grooves or recesses 38, wherein the front edge 47 in the running direction is provided as a cutting edge for the covering paper leaflets 39 separating from the tipping paper strip 2 or its material webs separating cut.

The knife drum 32 carries at its periphery transverse to the direction of rotation extending knife 34, which dive successively in circulation in the grooves 36 of the cutting drum 36. The cutting edges of the knives 34 are inclined at an angle to the knife drum axis so that the two ends of the cutting edge circulate on different cutting circles, starting with the dipping of the first cutting edge end into the corresponding groove 38 of the cutting drum 36 and dipping the second cutting edge end ends.

The cutting drum 36 has arranged in the circumferential direction of the cutting drum 36 conveyor segments 50 which have on the outside via corresponding bearing surfaces 40 for the tipping paper leaflets 30 and the tipping paper strip 2 or the material webs formed therefrom. Between the conveyor segments 50, the recesses 38 are formed as an interruption.

How out Fig. 1 shows, between the guide roller 29 for the uncut tipping paper strip 2 and the conveyor drum formed as a cutting drum 36, a cutter 62 is arranged to cut the tipping paper strip 2 in several webs 102.A, 102.B, 102.C by longitudinal cuts (see. Fig. 3a ). In one embodiment, the cutting device 62 can consist of two juxtaposed cutting blades or the like, so that a corresponding number of material webs or material webs are conveyed through the longitudinal section of each cutting blade, which are conveyed to the cutting drum 36. When using n (n = natural numbers) cutting knives or cutting devices, n + 1 material webs are created (n ≥ 1, 2, 3, ...).

In one embodiment, the cutter 62 may also include other slitter devices, e.g. Laser devices have. Preferably, the longitudinal cutting of the tipping paper strip 2 with fixed cutting knives, wherein the longitudinal cutting of the (already) glued tamping paper strip 2 is carried out in particular between the oscillator 44 and the cutting drum 36. In this case, in one embodiment, the longitudinal section or the longitudinal cutting of the tipping paper strip 2 can be carried out with fixed cutting knives or circular knives.

In particular, for the formation of three material webs 102.A, 102.B, 102.C (cf. Fig. 3a ) used according to two cutting blades, which are arranged in particular to the center of the tipping paper strip 2 symmetrical to each other. As a result, the cutting blades each have the same distance with respect to the edge of the tipping paper strip 2. In particular, in one embodiment, it is provided that the uncut covering paper strip 2 is glued by means of the gluing device 22 in such a way that two glue-free tracks are formed in the region of the longitudinal section of the covering paper strip 2 in order to reduce contamination of cutting blades for longitudinal cutting of the covering paper strip 2.

The cutting device 62 is arranged in front of the cutting drum 36 relative to the conveying direction of the tipping paper strip 2. On the cutting drum 36, the juxtaposed webs of material 102.A, 102.B, 102.C are cut by the engagement of the knives 34 in a cross-sectional process into side by side material web sections formed by sliding conveyor segments of the cutting drum 36 transverse to the conveying direction on the cutting drum 36 are spaced.

In Fig. 3a is a schematic representation of a top view of the cutting drum formed as a cutting drum 36 in a section of the circumference. The cutting drum 36 has a conveyor segment 50 with a support surface 40 for the longitudinally cut material webs 102.A, 102.B, 102.C, wherein the support surface 40 of the conveyor segment 50 is formed by three segment bodies 64.A, 64.B, 64.C.

When the webs of material 102.A, 102.B, 102.C are picked up, the segment bodies 64.A, 64.B, 64.C of the conveying segment 50 approximate relative to one another, so that the width of the segment bodies 64.A, 64B , 64.C transverse to the conveying direction of the width of the webs 102.A, 102.B and 102.C corresponds. In another embodiment, the width of the segment body 64.A, 64.B, 64.C in the collapsed state is greater than the width of the material webs or the uncut covering paper strip 2 conveyed to the segmented bodies 64.A, 64.B, 64.C.

The middle conveyor segment 64.A of the conveyor segment 50 is fixedly arranged on the drum body of the cutting drum 36, wherein the outer segment body 64.A, 64.C are designed to be displaceable with respect to the immovable conveyor segment 64.A. The segment bodies 64.A, 64.B, 64.C have radial suction air bores 65.A, 65.B, 65.C, so that upon application of a negative pressure to the radial suction air bores 65.A, 65.B., 65. C the conveyed material webs 102.A, 102.B, 102.C are held on the outer surfaces of the segment body 64.A, 64.B, 64.C.

Based on the conveying direction of the rotating cutting drum 36, a cutting body 66 with a cutting edge 67 is arranged on the rear side of the segment body 64.A, 64.B, 64.C. By transverse cutting of the webs of material 102.A, 102.B, 102.C, which are held on the bearing surfaces of the segment body 64.A, 64.B, 64.C by negative pressure in the transport area, arise web portions of finite length, which after the cutting of the material webs 102.A, 102.B, 102.C are spaced apart from each other by spacing the segment bodies 64.B, 64.C with respect to the stationary conveying segment 64.A in the middle transversely to the conveying direction.

In Fig. 4 is a cross section through the conveyor segment 64.A according to the in Fig. 3b drawn section line AA shown.

In the FIGS. 5a, 5b are still in accordance with the in the FIGS. 3a and 3b drawn section lines BB cross sections through the cutting drum 36 and the segment body 64.A, 64.B, 64.C respectively in accordance with the FIGS. 3a and 3b shown working positions of the segment body 64.A, 64.B, 64.C shown in the neck.

How out Fig. 4 shows, the middle conveyor segment 64.A between the Saugluftbohrungen 65.A axially parallel openings 68, in which guide rods for the outer segment body 64.B, 64.C are added. In order to move the segmental body 64.B, 64.C with respect to the central conveying segment 65.A in an axis-parallel direction during the rotation of the cutting drum 36, a guide rod 69 (see FIG. Fig. 5a, 5b ), which is connected to a laterally formed lifting link 70 for a conveyor segment 50. For example, the guide rod 69 is connected to the outer conveyor segment 64.C, so that during the rotation of the cutting drum, a lifting movement of the segment body 64.C is performed. A corresponding lifting means is also provided correspondingly for the second movable conveying segment 64.B on the cutting drum 36.

In the context of the invention, it is also possible that after transverse cutting of the tipping paper strip 2 in strip portions of finite length, the strip portions on the cutting drum 36 in collapsed segment bodies 64.A, 64.B, 64.C promoted and after longitudinal cutting of the strip portion in several web strips Web strips are laterally spaced by moving the segment bodies 64.B, 64.C apart.
