Abstract
An apparatus for three-dimensionally driving gripper rails in a multiple-pedestal press has raisable and lowerable guides for moving the gripper rails in a clamping and releasing direction in cross slide supports. The cross slide supports are movable in the clamping and releasing direction. The motion of the gripper rails in the clamping and releasing direction is brought about by a servomotor, which is secured at the level of the cross slide supports and which cooperates, with shaft portions extending from both sides thereof and embodied as spindles, with clasp nuts on the cross slide supports. In addition to the advantage of the direct drive for the clamping and releasing motion of the gripper rails, the region required by the tools in the working stages is utilized for accommodating the servomotors.
