Abstract

Press has a plasticising screw which simultaneously rotates and moves axially, and whose back end is directly fixed to the output shaft of a slow hydraulic motor with a coaxial ram to translate it. The back end is connected in translation to the movable element of the ram by a cage which encloses the motor.
