Abstract: A sheet feeder assembly (1) includes a bottom-feed sheet feeder (3) and a delivery table (5) positioned to receive sheets from the sheet feeder and deliver the sheets one at a time to a top-feed mechanism (205) designed to feed the top sheet of a stack of sheets in a manual feed tray of a printer (7) or the like. The top-feed mechanism includes a lifting support (204) for a stack of sheets. An exit end of the delivery table rests on and moves with the lifting support and delivers sheets one at a time to the top-feed mechanism. A balance mechanism (75) reduces the effective weight of the delivery table.

Abstract: A sheet feeder having a stack hopper for holding a stack of sheets, and feed belts for advancing the bottom-most sheet from the stack, is constructed to move at least one of the feed belts laterally toward and away from another of the feed belts while the belts are being driven. Preferably, side guides extend substantially to the end of the feeder, and extend both above and below the upper surface of belts to which they are adjacent. The belts extend between and around shafts of uniform diameter through the reach of lateral movement of the belts. The shafts are journaled in bearings mounted in such a way that they can be lifted out to change belts quickly and easily.

Abstract: A sheet feeder (1) having a stack hopper (9) for holding a stack of sheets (8), and feed belts (5, 6, 7) for advancing the bottom-most sheet from the stack, has traction belts (110, 111, 112) between the feed belts. The traction belts extend around a shaft (25) beneath the hopper and around a shaft (27) positioned intermediate the reach of the feed belts, a short distance short of separators (30, 31). The traction belts are preferably thicker than the feed belts and textured on their outer surface.

Abstract: In a friction sheet feeder for feeding sheets to an inserting machine, paper guide extensions are provided, connected to paper guides on the feeder and positioned and adapted to guide each sheet both laterally and vertically to the necessary position for the inserting machinery to which it is attached. The extensions are mounted to the paper guides so as to be adjustable up and down to allow for precise delivery of the sheets being fed. Paper hold downs are attached to the paper guide extension and a sheet stop photo cue is attached permanently to at least one of the paper guide extension to stop sheet in precise position until the inserting equipment pulls the sheet away. Preferably, the paper guide extensions are mounted to the paper guides with a single locking bolt and nut.
