Abstract (en)
[origin: US5125640A] A gripper bar fitted on drive chains and destined to grip and carry plate shaped sheets of material through printing, cutting and similar machines to produce a package characterized by the bar including a hollow profile on which the grippers are fastened. Every gripper consists of a flat spring attached at one end to a leading edge wall of the bar and having the other free end taking a rest position engaging a gripper counterpart which is situated on the trailing edge of the bar. The flat spring has a length greater than the width of the bar and passes through the bar before reappearing through a window on the trailing edge of the bar.
