为了增加抽吸夹具的保持力，至少一个销（17）被配置在夹紧脚（18）大致在中心。 由此可以采取的地方无滑动的传递中从压印滚筒（5）到转印滚筒上的印刷单元1片印刷（9）。 期间由吸附垫转印片材（12）的后部部分（15）的，所述销（17）能够穿透并在必要时在船头（12）刺穿它，。 在后一种情况下，有利的是布置在印刷滚筒（5）的圆弧每个弹性条（19）的长度的函数。

To increase the holding force of a suction gripper, at least one pin (17) is arranged in the gripper foot (18) approximately in the center. This can be done a slip-free transfer of the printed in a printing unit 1 sheet from the impression cylinder (5) to the transfer cylinder (9). When taking over the rear portion (15) of the sheet (12) by the suction pad, the pins (17) in the sheet (12) to penetrate and pierce these where appropriate. In the latter case, it is expedient to arrange each elastic strip (19) on the printing cylinder (5) in dependence on the length of the arc.
