Abstract
Abstract A multi-pass sorting machine includes a housing or supporting structure which has the configuration of an A-Frame. The A-Frame structure has a slanting front side supporting several individually functional devices and a slanting back side supporting other individually functional devices. The devices of the front side include an input feeder first transporting mechanisms, a singulating device, an accelerating mechanism, second transporting mechanisms, a bar code reader and associated electronic and computer equipment, a plurality of first sorting devices in the form of diverting vanes, an equal number of first pass stacker buffers, and a reversing member for transporting letters from the front side to the back side while at the same time retaining the same orientation of the letters to the planar surface as the letters go around the corner. The slanting back side supports a plurality of second sorting devices in the form of diverting vanes, an equal number of second pass stacker buffers, and an automatic mail tray loader.
