The belt roller has coupling catches (34) which are movable from the rest position to the working position and from the working position to the rest position by running on control surfaces rotating relative to the catches. The coupling unit has a hub (30) on the drive side, on which the coupling catches are extendably supported. The coupling also has a cage (32) releasably fixed to the housing on which the control surfaces are formed. |
