In the following figures, the same or similar elements or corresponding parts are designated by the same reference numerals, so that a corresponding renewed idea is disregarded.

In the FIGS. 1 to 3 In each case different views of a transport device for a tipping paper strip 25 are shown. The tipping paper strip 25 is from a (not shown here) Bobine withdrawn, which is arranged on a reel-to-reel machine. The tipping paper strip 25 is fed via a plurality of rollers 11, 12, 13 to a threading device 10 (FIG. Fig. 4 ). After threading the covering piercing strip 25 into a transport carriage 15 (cf. Fig. 4 ), the carriage 15 by means of two tension cables 16, 17, which are arranged on the transport carriage 15, moved through the different sections of the transport device and guided.

The transport device has in the illustrated embodiment, two horizontal transport areas A, B and a formed therebetween vertical transport section V.

In the horizontal transport section A a rectangular in cross-section transport channel 30 is formed for the transport carriage 15. According to the invention, it is provided that the geometric dimensions of the transport channel 30 in the interior substantially correspond to the outer dimensions of the transport carriage 15, so that the transport carriage 15 is hereby guided in a rail-like manner in the transport section A.

In order to transfer the transport carriage 15 from the horizontal transport section A into the vertical transport section V, a deflection device 40 is provided. In addition, a further deflection device 41 is provided in order to subsequently transfer the carriage from the vertical transport section V into the upper horizontal transport section B.

Im in the Fig. 1 to Fig. 3 illustrated embodiment, the horizontal transport section A and the horizontal transport section B are arranged at an angle to each other, so that the tipping paper strip 25 is twisted or getwistet in the region of the vertical transport section V. This situation is in Fig. 2 shown, for the sake of clarity of the representation of elements has been omitted.

The deflection devices 40, 41 have a roller guide for the transport carriage 15, wherein the tension cables 16, 17 are guided via groove guides in the rollers of the deflection devices 40, 41

In order to guide the transport carriage 15 in the region of the vertical transport section V, a guide rail 45 is arranged between the lower deflection device 40 and the upper deflection device 41 and has a twist. This is in Fig. 3 illustrated.

After the transfer of the tipping paper strip 25 from the vertical transport section V in the horizontal transport section B, the clamping of the tipping paper strip 25 on the transport carriage 15 is released at the end of the transport section B. At the end of the transport section B, a traction winch 19 is arranged, on which the traction cable 17 is completely wound up. At the beginning of the transport section A is also a pull cable 18 for the pull cable 16 is provided.

By the synchronized drive of the two Zugseilwinden 18, 19 of the transport carriage 15 in the transport sections A, V, B is moved back and forth. After the clamping of the tipping paper strip 25 in the upper horizontal transport section B has been solved, the tipping paper strip is conveyed by means of further conveyor means for further processing on a machine of the tobacco-processing industry, e.g. Promoted cigarette rod machine.

In the context of the invention it is possible, after delivery of the tipping paper strip 25 the transport carriage 15 in its initial position ( Fig. 4 ) to drive back while the tipping paper strip 25 is conveyed in the opposite direction of transport.

The transport carriage 15 has a spring-loaded clamping device with a clamping bracket 20, wherein in the receiving position of the tipping paper strip 25 of the clamping bracket 20 is released from the transport carriage 15 so that the end of the tipping paper strip 25 between the clamping bracket 25 and the transport carriage 15 is jammed.

After the threading of the tipping paper strip 25, the transport carriage 15 by means of the cables 16, 17 through the transport channel 30 (FIG. Fig. 1 ) drawn. Subsequently, the transport carriage 15 is brought together with the clamped tipping paper strip 25 by the deflecting device 40, the vertical transport section V and the deflection device 41 in the horizontal upper transport section B.

In Fig. 5 a section of the horizontal transport section B is shown, for reasons of better representability, the transport section B is reversed. In the conveying direction of the tipping paper strip in the horizontal transport section B is before the cable winch (see. Fig. 2 , Reference numeral 19), a transfer holder 50 is provided. The transfer holding device 50 is activated after the tipping paper strip has been released from the transport carriage by releasing the clamping device of the transport carriage.

The transfer holder 50 consists of a pair of rollers with a lower roller 51 and an upper idler roller 52.

The roller 51 is driven by a motor 54. In order to achieve a clamping of the tipping paper strip between the roller 51 and the roller 52, the roller 52, which is arranged on a holder 56, via a linear actuator 53 transversely, in particular perpendicular, linearly moved to the running direction of the tipping paper strip until the tipping paper strip between the Rolls 51 and 52 in a contacting manner.

The rollers 51, 52 are brought together after the transport carriage has pulled the tipping paper strip through the channel of the horizontal transport section B and before the clamping of the tipping paper strip is released. By the clamping of the tipping paper strip between the rollers 51, 52, a slipping back of the tipping paper strip is prevented. By means of the driven roller 51, the pinched tipping paper strip is further conveyed until the tipping paper strip is detected by another working member, for example a further processing machine of the tobacco-processing industry. Subsequently, the rollers 51, 52 spaced by activation of the linear drive 53, so that between the rollers 51, 52 of the transport carriage in its starting position at the lower end of the transport section A (see. Fig. 1 . Fig. 4 ) is reduced.
