Abstract (en)
[origin: EP2623658A2] The system has a hook driven by a hook drive in a hook race of a hook race carrier. A guide bearing comprises two drive cams located between the drive and the hook, where the cams are driven in such a way that each cam enters once temporarily into an opening in a back of the hook, during rotation of the hook. The cams are displaceable in a radial direction in two slots in the bearing, and are temporarily movable from a single engagement in the opening to a double engagement, during displacement and subsequently again to a single engagement.
