ABSTRACT:
Rotary press machine including dies, pairs of upper and lower punches with a part of each lower punch being movable in a respective die to selectively enable formation of a cavity in the die, a feeding system for feeding powder material into the cavities, when present, in a feeding stage, a pressing system for pressing the upper and lower punches together in a pressing stage and a tablet ejection system for ejecting formed tablets from the dies in a tablet ejection stage. The upper and lower punches are rotated sequentially through the feeding stage, the pressing stage and the tablet ejection stage to thereby enable formation of tablets if powder material is feed into the cavities in the dies. To enable selective formation of tablets and thereby optimize production thereof, an adjustment mechanism is provided and enables selective formation of the cavities in the dies.
