Rotary press comprising a rotor rotatably driven about a vertical axis, said rotor exhibiting a die plate and upper and lower punches which are vertically guided in guides of the rotor working together with die holes in a die plate, at least one press station which exhibits an upper and a lower pressure passed by the punches and through which the punches are moved towards the die hole in order to compress the material in the die hole, characterized in that the rotor is provided with means which act upon compacts or parts thereof which adhere to the pressing surface or which means eliminate or prevent an adherence of a compact or parts thereof to the pressing surface of the upper punch, respectively, during the return stroke.

Rotary press

A die for a rotary compression press, comprising a die holder axially supported in a guide bore and a die insert which is seated in the end-side bore of the die holder via a trunnion-shaped projection and is adapted to be mounted via releasable fastening means, wherein the projection is helically guided in the bore between axially spaced stops and is biased by a spring towards the associated front-end face of the die holder.

Die for a rotary compression press

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.
