Abstract

A rotary press with a stand, a rotor rotatably mounted around a vertical axis in the stand and being driven, which has an upper and a lower compression punch accommodation for upper and lower punches which co-operate with bores of a die plate of the rotor, and upper and lower control cam elements which can be detachably fastened on a cam carrier of the stand and which guide heads of the compression punches by means of control cams during the rotation of the rotor, characterized in that at least one control cam element, guiding the compression punch heads radially outside or radially inside, can be detachably fastened on the carrier and can be moved radially away from the punch heads when the fastening means is detached, so far that by-passing the punch heads, it can be taken out parallel to the axis of the rotor, towards the upside or towards the bottom side, respectively.
