Abstract
In a press with a plunger which is supported by an elastically deformable support structure so as to be linearly movable but otherwise rigidly engaged and with a drive arrangement for the controlled movement of the plunger, the drive arrangement includes no friction or antifriction support joints so that the plunger guide structure is not affected by position errors generated by oil films in bearings or wear of bearings generated by the high press forces effective during operation of the press which could squeeze oil films out of bearing gaps.
