ABSTRACT:
A connecting assembly for connecting a multitude of axially extending punches to a rotatable punch drive plate in a rotary press having a die plate supported for rotation in a given plane and forming a multitude of die cavities. Each of the multitude of punches is supported for axial reciprocating movement in an associated respective one of the die cavities, and the drive plate engages the punches and has a generally flat shape extending at an angle to said given plane, and rotation of the die plate and the drive plate reciprocates the punches in the die cavities. The connecting assembly connects each punch to the punch drive plate for limited swinging movement to maintain the punch axially aligned with the associated one of the die cavities as the die plate and the drive plate rotates.
