Abstract

In a press an hydraulic adjusting cylinder connected to the slidable cross-piece of the press has a stroke matching the range of movement of the press and a number of hydraulic press cylinders of short stroke are provided for executing the working strokes of the press. The press cylinders are each couplable to the slidable cross-piece by a coupling including a coupling rod and a stationary clamping jaw and a pressable clamping jaw cooperating with the coupling rod, the pressable clamping jaw being activated by at least one single acting hydraulic cylinder.
