<p>A power stacker (11) for collecting delivered articles such as envelopes from a mailing machine has a support housing (12) having a deck (31) mounted along the housing. A registration wall (145) is fixably mounted to the housing (12) and extending generally perpendicular relative to the deck (31). A stack wall (111) is slidably mounted to the housing (12) at one end of the deck (31) and has a reclined surface (115) extended generally upwardly from the deck (31), the stack wall (111) being slidably mounted to the housing (12) such that the stack wall (111) can be horizontally displaced relative to the deck (31). Support rods (117,119,121,168) are provided for providing article support between the deck (31) and displaced stack wall (111) as well as between the registration (145) and displaced stack wall (111). Threaded hubs (101, 103, 157) are provided for causing the delivered articles to be collected against the stack wall (111) and assume a generally parallel stacked orientation generally parallel to the reclined surface (115). A power stack wheel assembly (200) extends in a cantilevered fashion from the registration wall (145). Stack wheels (222,224) are overrunning on a clutch (220) until power to climb envelope lead edges is needed. <IMAGE></p> |
