ABSTRACT:
A workpiece manipulator assembly for a forging press having a press ram comprises a workpiece rotating mechanism including a rotary drive system for rotating a workpiece in peripheral direction. The rotary drive system is operated by a drive motor running at a preselected constant speed to rotate the workpiece about an axis of rotation. An arresting assembly stops the rotary movement of the workpiece before and during a pressure contact phase for the press ram. The rotary drive system is adapted to rotate a driven worm which produces rotary movement to the workpiece rotating means and is mounted for axial displacement. The arresting assembly includes an axial drive unit for predeterminably controlling axial displacement of the driven worm to effect the arresting of said rotary movement.
