Abstract:
A rotary press for pressing cylindrical compacts, in particular tablets, comprising a rotatably driven rotor including a die-plate which has die bores and upper and lower guide means for upper and lower, the rams cooperating with the die bores, a pressing station having an upper and a lower pressure roller whereby a compacting force is applied to the upper and lower rams when passing the pressing station, each upper and lower ram having an annular toothing at the circumference thereof, and an opposed toothing in the range of the pressing station for the cooperation with the annular toothing of the rams, the opposed toothing being formed by a rotatably supported gear a predetermined braking torque being applied to the gear, the braking torque being selected such that it is smaller than the torque which is necessary to rotate a ram under maximum pressing force in the pressing station.
