Abstract
A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.
