The cylinder piston unit includes at least one working chamber which communicates with a reversible continuously operating working pressure medium supplier having a variable output. At least one action stroke pressure unit is operatively connected to the punch and acts upon the same only during a segment of the motion of the punch in an action stroke direction. The action stroke pressure unit is temporarily connected to a pressure medium source having a higher pressure than the pressure produced by the pressure medium supplier.
