Abstract
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.
