ABSTRACT:
A rotary press with a rotary driven matrix table for holding matrixes having boreholes. During rotation of the matrix table, top and bottom dies are moved in their axial direction towards and away from each other for pressing injected moldable material in the boreholes of the matrix. For production of profiled articles, the bottom and/or top dies are constructed as one outside and at least one inside die which are movable independently of each other. For pressing movement of the outside and inside dies, at least one profiled press roller is provided to assign different pressing paths to the outside and inside dies. The press rollers are provided with a rotary deep-cut groove for guiding the inside die to which a nose-shaped guide head is assigned for engaging the groove. The press rollers are constructed as two exterior disks for guiding the guide surfaces, and one interior disk for guiding the inside die by means of the nose-shaped guide head. The interior disk is located eccentrically, with the eccentricity being adjustable.
