Abstract

The invention relates to a rotary press with anti-rotation secured shafts and exchangeable punches attached thereto. The rotary press comprises a punch turn which is universally ensured with the use of anti-rotation secured punch shafts, meaning, not only with rotation-symmetrical but also with roll-guided punches, is solved in such a way that the exchangeable punch is executed in a rotational manner, where a circumferential recess in the stem of the punch is envisaged, into which a component such as a spring thrust piece engages for the purpose of fixation, and that the shell surface of the exchangeable punch indicates a zone which interacts with a zone of the external component, either force-locking or positive locking, in such a way that the punch receives a turning movement at a defined point of the pitch circle of the punch circumference.
