Abstract
A method of and apparatus for separating and feeding workpieces of limp material one at a time and one another from the bottom of a stack of the workpieces wherein the stack is supported at the bottom with a gap in the support for exposing a portion of the bottom surface of the bottom workpiece, the support being movable to move the gap away from and back to a forward position. The portion of the bottom workpiece exposed in the gap in the forward position is fed rearward to form a loop in the bottom workpiece, the loop being gripped and pulled down which the support is moved to move the gap away from its forward position, the support then acting to peel the bottom workpiece away from the next workpiece above, followed by the release of the grip on the loop to release the bottom workpiece for being carried away.
