ABSTRACT:
An apparatus for transferring a relatively flat object from a work station along a transfer path includes an upper tooling within the work station for locating the object in a ready position by causing an upper surface of the object to adhere to the tooling. The object is thus unsupported along its lower surface. A manifold forming an orifice is located adjacent to and directed toward the ready position, and is connected to a source of compressed gas. A valve initiates and discontinues flow of pressurized gas through the orifice. A control system controls the valve to direct a stream of pressurized gas through the orifice when an object is located in the ready position, thereby causing the transfer of the object in free flight from the work station.
