Abstract
A multi-stage press includes support columns; a press stage including tools for deforming a workpiece; an empty stage adjoining the press stage in a direction of a length dimension of the multi-stage press and being situated in a zone of the support columns; a gripper rail being formed of a first gripper rail lenth portion situated in the press stage and a second gripper rail length portion situated in the empty stage; a plurality of workpiece gripper assemblies mounted on the gripper rail; and a tool table normally situated in the press stage and being removable therefrom in a direction transversely to the press length. The workpiece gripper assemblies are independently shiftable relative to one another along the gripper rail and the gripper rail assemblies normally supported on the second gripper rail length portion are shiftable onto the first gripper rail length portion. The gripper rail assemblies have a normal operating position in which the gripper rail assemblies are situated on the first and second gripper rail length portions in a mutually spaced relationship with respect to one another and they have a replacement position in which they are situated solely on the first gripper rail length portion in a mutually contacting relationship with respect to one another.
