ABSTRACT:
A feeder mechanism for feeding single sheets, folios or multiple-ply material of paper or the like to subsequent processing machinery. A stack of sheets is partially tilted and edge portions of the front sheet are grasped and bent over by alternately approaching suction devices. While one of the suction devices engages the edge portion of one sheet, the previously detached sheet is being engaged by a conveyor wheel which pulls it completely from the stack.
