Abstract: A new and improved mail sorting system, which is able to dramatically increase the throughput sorting volume of mail pieces or articles, comprises the incorporation of a plurality of cross-circulation path (CCP) conveyors within a conventional looped or folded conveyor belt system whereby, in effect, mail pieces or articles can be effectively removed from primary conveyor flow path sections so as to create gaps or spaces upon the primary conveyor flow path sections into which additional mail pieces or articles can be introduced through means of a second input or infeed port. In addition, a plurality of the new and improved mail sorting systems can be integrated together into a multi-system mail sorting system wherein off-shoot or auxiliary outfeed conveyor belt sections can feed pieces or articles of mail from any particular one of the mail sorting systems to the second input or infeed ports of the other mail sorting systems so as to render the overall system still more efficient.

Abstract: Objects such as pieces of mail are stacked without significant contact therewith by producing laminar air flow over a surface which defines or parallels a desired movement path for the objects. The objects are placed and form a barrier between the laminar air flow and ambient air and movement such as turning an edge of the object to prevent impact on other objects and regulation of direction velocity an kinetic energy of the motion of the objects is regulated by the Coanda effect of the laminar flow. The object thus provides an acoustic barrier to reduce generation and propagation of noise by the high pressure air used to create the laminar flow. An air amplifier reduces the volume of high pressure air required to provide control of object motion.
