Abstract

The press has hydraulic cylinders (9) on the lower part of the fixed frame (1), connected to an oleo-pneumatic reservoir (12) acting as buffers, with contact portions (10) which are contacted by abutments (11) on the press ram (2) which can be adjusted so that a given amount of the force of the ram is opposed at the end of the working stroke. In an alternative design, a control device (13, 14) operated by the travel of the ram (2) actuates a control valve system (15, 16) so that two degrees of force are exerted by the buffers.
