Abstract: An air tunnel track interface attaches to a can testing apparatus for receiving cans from the output of the can testing apparatus and transferring them to a conveyor system. The air tunnel track interface comprises two parallel substantially U-shaped tracks each having an air chamber, a plurality of air louver jets and diverging ends, and a pair of parallel discharge plates each having diverging cutouts for mating with the diverging ends of the U-shaped tracks.

Abstract: A conveyor system for feeding containers along a path includes a pair of plenums located on opposite sides of the path. Each plenum has an inner wall which has apertures along the center thereof, with flanges extending from each wall to define chambers or guide channels that receive opposite ends of the container. The system further consists of rigid pneumatic conduits for delivering pressurized fluid from a centrifugal blower to the plenums. The pressurized fluid is introduced into the plenums and flows through the apertures to substantially suspend the containers in the chamber. The pneumatic conduits and the centrifugal blower are integrally associated with the dual plenums, thereby structurally enhancing the entire conveyor system.
