PNEUMATIC REGISTRATION AND CLAMPING APPARATUS Abstract the Disclosure In a first embodiment, a stop having a plurality of ports is connected to and covers an end of a rectangular sleeve having a movable wide wall. 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. After the sheet has been registered, the movable wide wall is moved towards the other wide wall of the sleeve. If a sheet is wrinkled, such movement flattens the sheet. 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.
