ABSTRACT:
Apparatus for turning over a workpiece, such as a metal stamping, including a turnover shaft. A pneumatic piston and cylinder rotates the turnover shaft in a cammed rate of motion from an initial position to a final position. A vacuum-operated workpiece support is rotated with the turnover shaft and is adapted to engage a metal stamping to swing it with the turnover shaft. The workpiece support is connected by a gear box to the turnover shaft in such a manner that as the workpiece is swung to an upside down position, it is also rotated about a second axis with respect to the turnover shaft.
