Abstract
In a transfer press, the gripper rails consist of gripper rail parts located at the press and exchangeable gripper rail parts. In operation, the gripper rail parts must be rigidly connected with one another. For this purpose, a coupling element utilizing a rotary tightening device is inserted in one gripper rail part and has a tension rod which can be braced with T-shaped head behind a coupling surface of a gripper rail part located at the side of the press. Flange facings are machined into front faces of the gripper rail parts. These flange facings have flat surfaces which extend parallel to the direction of the lifting and lowering movement of gripper rail parts and the direction of the opening and closing positioning movement of a sliding table carrying exchangeable gripper rail part. The gripper rail parts are separated along the flat end surfaces of the flange facings and do not require longitudinal displacement to provide a separation gap.
