ABSTRACT:
A method and an apparatus serve to secure a gripper tool detachably to a movable crossbar of a transfer press. The gripper tool has two saddles, with spacing between them, which are brought into engagement with two bearings mounted on the crossbar and locked in a defined engagement position. To attain faster, simpler assembly, the gripper tool is introduced in an inclined position relative to the crossbar, by at least one protrusion of rounded longitudinal section or tapering in wedgelike fashion, on the first saddle, into a correspondingly rounded or V-shaped narrowing recess in the first bearing. The second saddle is then pivoted toward the crossbar. In the process, wedge faces on the second saddle and on the second bearing press the protrusion axially against the wall of the recess by the force of gravity. In the end position, the second saddle is locked to the second bearing.
