ABSTRACT:
An apparatus for mechanically removing a thin sheet of material, such as food dough, from a stack of such sheets and depositing the sheet on a moving conveyor in a desired orientation so that a food filling may be automatically placed on the sheet of material. The apparatus picks up the thin sheet with suction nozzles, carries the thin sheet to the conveyor where pressurized air is delivered to the nozzles to release the thin sheet from the suction nozzles. A combined hydraulic-pneumatic lifting mechanism is provided to incrementally lift the stack of thin sheets to the pick-off apparatus.
