Abstract:
In a device wherein a tape is supplied by a feed spool on a feed spool core and the tape is taken up by a take-up spool on a take-up spool core, a slipping clutch for the torque-limiting transmission of force between the feed spool core of the feed spool and the take-up spool for the winding and unwinding of the feed tape from the feed spool core and to the take-up spool core, the slipping clutch comprising a first clutch part of annular cross-section and a second clutch part in the form of a shaped element the improvement being in that, the annular clutch part engaging by friction at several contact points spaced apart from one another around its circumference with associated contact surface zones formed on the shaped element and one of the two clutch parts being connected to the feed spool core of the feed spool, and the other clutch part being connected to the take-up spool core, the shaped element is a rigid dimensionally stable moulding while the annular first clutch part consists of a flexible material, whereby in the event of relative movement between the two clutch parts, the shaped element deforms the annular clutch part via the contact points.
