ABSTRACT:
Apparatus for lifting successive topmost stacks of large paper sheets and the panels beneath such stacks off a pile of superimposed stacks and panels has one or more separating units each employing a roller which is caused to bear upon the topmost sheet of the topmost stack of the pile and a sword which is aligned with or is disposed at a level slightly below the topmost panel of the pile and is caused to penetrate into the pile so as to lift the topmost stack with the topmost panel preparatory to automatic shifting of the lifted stack and panel sideways into a processing machine. The distance between the lowermost portion of the roller and the plane of the sword is adjustable to permit for subdivision of piles having thicker or thinner stacks. Any sheets which are lifted with a panel and belong to the stack below the lifted panel are stripped off the lifted panel by a continuously driven friction wheel which enters the gap that is formed by the sword. A hold-down device is employed to press upon the stack below the gap during transfer of the lifted stack and panel into the processing machine.
