Abstract
Mechanism for separating the uppermost pliant sheet of a stack of such sheets from the stack including a rotatable friction drive wheel effective on the longitudinal center line of the uppermost sheet for initially moving the sheet rearwardly, and a pair of downwardly tapered posts at the rear face of the stack and on opposite sides of the center line which cause the uppermost sheet to bow upwardly away from the stack particularly on its side edges for thereby effectively separating the sheet from the stack and allowing it to be driven subsequently in the forward direction to free it completely from the stack.
