摘要

The control roller (44) of the claws works together with a turnably driven control segment (33) that has a first control curve (37) as a turning motor. There is a further control curve (46) that works together with a control roller of a roller lever (43, 34) which can be coupled on the control segment. The first control curve and the further control curve may have a common area with the same control contour. A remote operated positioning element (49) may be arranged on the roller lever. There is a locking element (52) arranged in working connection with the two roller levers. The locking element may be operable via the positioning element.
