Abstract

Tablets 3 are produced by press forming in dies in a rotary die plate 1 passing beneath a pressing station 2. Downstream of the pressing station 2, there are an accepted tablet outlet 5 and a rejected tablet outlet 6, with a vertically movable guide wall 7 determining which path each tablet will follow. The press force pertaining to each individual pressing operation is measured, and the guide wall 7 is actuated in dependence on the measured individual press force, and is also controlled in dependence on the rotational speed of the die plate 1 and on the position of a die relative to the guide wall 7. <IMAGE>
