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.

Abstract: The front feeder for a high speed machine for handling mixed mail, including a nudger drive assembly for advancing the mail pieces while maintaining registration and for fluffing a stack of mail contributing to preshingling of the mail as it is advanced downstream, angled decks and a back prop for a guideless hopper region, a tamper subsystem for maintaining registration of flapped envelopes, and structure configured to guide one envelope flaps along a slot for downstream sealing purposes.

Abstract: The belt tensioning apparatus is comprised of a generally elongated housing having a first section and a second section. The second sections includes a lengthwise slot formed therein. A slide member having a roller rotatively mounted at one end and a tab formed at the other end is slidably mounted in the housing such that the slide member tab is located in said slot. A spring is mounted in the housing second section for applying a biasing force on the tab.
