Beschreibung
Zusammenfassung:	A press comprises a frame made up of two crossheads rigidly interconnected by way of uprights with two rams mounted therebetween one above the other. One of the rams has a built-in nut with a non-self-stopping thread to be thereby engaged with a screw rigidly connected to a die holder mounted for rotation in the other ram and geared to a drive for its translatory motion. Forced interaction between the nut and the screw is effected through a drive provided to actuate the ram with the nut and controlled from the drive of the die holder. There is provided a clearance of sufficient size between the rams to permit a specified angle of rotation of the die holder.
