ABSTRACT:
A method and apparatus for removing the lowest workpiece from a stack of a plurality of substantially similar workpieces. A horizontal shuttle has a lip on its edge, and is driven in one direction to remove the lip from a void beneath the stack, thereby permitting the stack to fall. The lowest workpiece drops into the void, and the next higher workpiece rests on the upper surface of the shuttle lip. The shuttle is subsequently reversed to drive the workpiece into a slot in a vertical clamp body. The clamp body is driven downwardly, thereby driving the workpiece downwardly, to be acted upon by a secondary device, such as a conventional degating apparatus.
