PNEUMATIC REGISTRATION APPARATUS Abstract of the Disclosure In a first embodiment a stop having a plurality of ports is connected to and covers an end of a rectan- gular sleeve. In a region near the stop a narrow wall of the sleeve also has a plurality of ports. A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports. With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop. In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered. In a third embodiment, similar to the first, a manifold is coupled to the ports and a vacuum pump is coupled to the manifold to accelerate registration. In a fourth embodiment, similar to the third, the pumps are replaced with a reversible pump to register and discharge a sheet.
