ABSTRACT:
A method and apparatus for singly removing the bottom one of a sheet from a stack of sheets, and utilizing counter rotating discs or plates which sweep the bottom sheet toward its opposite edges and thus create a flat and smooth bottom surface for contact by suction cups to remove the sheet from the stack. The plates are adjustable relative to the widths of the sheets, to thereby accommodate various widths of sheets. An intermediate or central portion of the lower sheet of the stack is made smooth and flat for contact by a suction cup which can therefore remove the sheets at high speeds.
