Abstract: A press machine includes a plurality of press units. Each press unit has a die opening and cooperating upper and lower punches which are slidable into an extended, inward position in the die opening. Each press unit is successively advanced into a punching position where the upper and lower punches are positioned in the extended, forward position in the die opening for pressing material into a compact body. A compensator is positioned at the punching position for exerting a punching force onto upper and lower punches advanced into the punching position. When the punching force is applied, the displacement of the upper and lower punches is compared with a reference standard displacement indicative of the actual, undisplaced position of the punches just prior to the application of the punching force. The punch force is adjusted if necessary so as to obtain equal displacement of upper and lower punches and at the same time and maintain the correct density of the resulting compact, finished bodies.
