摘要

The device (104) has two force transmission devices (118, 138) arranged at opposite ends of a curved retractor and/or compression device (108), where each transmission device comprises plate-like contact areas. The transmission devices are formed as suction cups and arranged with a ball joint at the retractor and/or compression device in an articulated manner. The retractor and/or compression device comprises piston cylinder units (110) that are chain-like switched one behind the other. A positioning adapter is provided in a positioning suction cup (156). Independent claims are also included for the following: (1) a positioning and retaining system comprising a vacuum distributor plate (2) a method for folding blanks.
