摘要： A method and apparatus for ensuring sheet separation of a single sheet workpiece from a stack of workpiece sheets which consists of a lifting assembly having at least three spaced sets of sheet workpiece holding suction members with at least a poriton of one set being reciprocatable in a vertical movement to cause flexure of a sheet being raised by the lifting device to cause separation of an underlying sheet which may have adhered to the sheet being lifted.
