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.

Rotary compression press

A tablet rotary compression press for the manufacture of multi-layered tablets, comprising a rotationally driven rotor which has a die-plate with die-plate bores and top and bottom rams aligned towards the die-plate bores which are guided in ram guides of the rotor and are axially actuated by stationary control cams, an insertion device for a portion of the tablet-forming compacts which has two or more arms guided in a radially movable manner at the each end of which a compact is held and can be aligned towards a die-plate bore, wherein said rotor has circumferentially included thereon a support ring or support surfaces on which the compacts can be deposited in the positions approximately aligned towards the die-plate bores, the radial arms are disposed in the rotor, rotate therewith, and have radially movable gripping portions adapted to be radially moved to each other, and the rotor has provided therein a stationary guide with first and second guide cams the cam followers of which are interacted with by the gripping portions in order to grip a compact on the support ring or a support surface, to bring it into alignment with the die-plate bore, and to release it again.
