ABSTRACT:
In a press comprising upper and lower turntables for carrying respective sets of upper and lower press tools, each upper press tool is movable to an operating position in which said press tool is adapted to be coupled to a ram. To ensure a free access of the workpiece to the press tools adjacent to the lower press tools, each lower press tool is mounted in the lower turntable to be individually vertically displaceable relative thereto. Only the lower press tool which is in operating position is supported in the frame and the other lower press tools are lowered.
