WORKPIECE TREATING APPARATUS

摘要

A workpiece treating apparatus includes a slatted barrel for holding the workpieces during rotation of the barrel. A draw bar is disposed generally parallel to the barrel slats and has workpiece engaging pawls thereon. The draw bar is mounted for oscillatory movement and for rotational movement about its own axis so that the pawls can engage the workpieces and pull them forward in the barrel and can then be disengaged from the workpieces whereby the pawls may return to their original position.
