ABSTRACT:
A rotary tablet press has a rotating mold table and top and bottom plungers, which can move reciprocally in plunger guides, coaxially with the molds. The reciprocating motion of at least the bottom plungers is cam-controlled and these plungers are acted upon by a damping element to prevent an overshoot of their movement. To ensure an action which is as free from wear and is as maintenance-free as possible whilst maintaining constant damping of the bottom plungers, it is proposed according to the invention that the damping element consists of at least one magnetic element which acts on the plungers.
