Abstract: In a press having an upper punch and lower punch and a tool mount to be inserted into the press and connected to the lower punch via a lower coupling plate and to the upper punch via an upper joining piece, and a framework mounted displaceably on a base plate of the mount and consisting of connecting rods rigidly connecting the lower coupling plate with the matrix holding plate, die carriers being moved relative to the base plate from their filling position downward into the compacting position and from the compacting position into the ejecting position, which corresponds to the filling position (the so-called ejection method), at lease one additional die carrier, like the matrix holding plate, works by the withdrawal method, this die carrier being moved from the filling position downward into the compacting position and from the compacting position downward into the withdrawing position.
