ABSTRACT Apparatus for preparing dies for a platen press comprises a lower bolster (1) and an upper bolster (3) between which a stack (120) can be in- serted on sliding rails (6) and (7). The stack (120) is set under pressure by means of a hydraulic plate covered by a membrane (41), the rim-of which is guided by support-blades (43 to 46) and blade-guides (47 to 50). The membrane (41) itself rests on a piston (52) acting on the stack (120). This device allows the various dies to be used in a platen press for processing cardboard or paper, to be constructed outside the press, and therefore minimizes the down time of the press.
