- EP 00 94 631 B1 shows a device for pulling in a material web by means of a rope. This rope drives guide rollers via a switchable clutch.
- the invention is based on the object / devices to provide for driving a guide roller.
- the object is achieved by the features of claim 1.
- the guide roller is only occasionally driven by the finite traction means, d. that is, as long as the traction device is in the vicinity of the guide roller. This eliminates the need for additional controls for switching the drive of the guide roller. The guide roller is therefore only driven when the traction means comes close to the guide roller.
- the guide roller accelerates smoothly, with little jerk, with little repercussions on the traction mechanism.

- the mass of the centrifugal body 19; 21 limit the transmissible torque.
- the clutch can thus be designed to be torque-adjustable by making the preload of the return spring 42 adjustable by changing the spring travel.
- the guide roller 1 is gradually brought to a circumferential speed which is the flow rate Roller chain 3 corresponds.
- the front side should be slanted, z. B. Angle Alpha equal to 45 °.
- the peripheral speed of the guide roller 1 depends on the partial diameter of the gear wheel 17.
- the partial diameter diameter r can correspond to the diameter of the guide roller 1, be smaller or larger than this.
- Retraction speed of the roller chain 3 is. This ensures that the guide roller 1 is approximately accelerated when the paper web start arrives at the feed speed.
- the guide roller 1 is now driven by the friction effect of the running paper web.
- a guide roller 51 has support rings 52 which support the roll shell 4 and which are somewhat removed from the ends 12 of the guide rollers 51 are arranged away.
- the support ring 52 has in the axial direction of the guide roller 51 and coaxial to the axis 8 bores 53; 54, in which in the axially parallel movement direction C guide pin 56; 57 are guided.

- a screw-guided coupling sleeve 28 is arranged, which is connected to a flange 29 on a side carries a friction lining 31.
- the guide roller 51 is started as follows. The power flow runs over the gear 17 and the hub 16, the coupling sleeve 28 screws are moved in the axial direction C and against the force of the return spring 42 with the friction lining 31 against the pressure ring 58 Guide roller 51 presses. A gap 35 with the gap width d which is located between the friction lining 31 and the pressure ring 58 - as a counter bearing - is closed. There is a frictional entrainment of the guide roller 51.
- the arranged between the support ring 52 and the pressure ring compression springs 62; 63 serve to limit the torque so that the clutch coupling 64 exerts a defined compressive force.
- the friction lining 31 shown in the first embodiment shown in FIG. 1 act as a torque limiter against a spring-loaded pressure ring 58. This is particularly advantageous if the slots 36 to 38 run at an angle alpha to the radial plane 39 that is greater than zero.
