Reverse belt singulating apparatus

Abstract

The reverse belt drive assembly is mounted to an envelope feeding apparatus. The envelope feeding apparatus includes a deck along which sheet member is caused to traverse by a drive assembly. The reverse belt drive assembly includes a first frame pivotally mounted to the apparatus above the deck and drive assembly. The first frame rotatively supporting a plurality of first and second rollers such that respective ones of the first and second rollers are in longitudinal spaced apart relationship. A first endless belt extends around respective ones of the first and second rollers. A second frame is pivotally mounted to the first frame. The second frame rotatively supporting a plurality of third rollers axially aligned to the first rollers and a plurality of fourth rollers, respective one of the third and fourth rollers being in longitudinal spaced apart relationship and having a second endless belt extending around respective ones of the third and fourth rollers. A plurality of springs biasing the first and second frame members downwardly against the deck. A motor drives the rollers to rotate in a direction opposite to the drive assembly.
