ABSTRACT:
A tabletting machine having a ring-shaped die table rotatable about a generally upwardly extending axis and having dies arranged at a die surface. Punches supported in the die table and reciprocably driven with respect to the dies co-operate with punches semi-rigidly mounted on a rotatable hub to form and eject tablets from the dies. The hub is rotated to move the punches mounted thereon in a circular path to enter and exit the dies in a predetermined sequence. Individual pump means associated with the punches in the die table and means for catching and extracting loose tabletting material falling from the dies serve to reduce contamination of the many parts of the machine by the tabletting material.
