Abstract: A sheet collection apparatus for stacking sheets delivered thereto face-up in the order 1 to n with sheet 1 on the top of the stack. The apparatus includes one or more collection trays, such as the bins of a sorter which are indexed past a feed throat. Retractable support arms at the throat support the sheets already in a bin opposite the throat during delivery of a sheet thereto whereby the sheet enters the bin below the support arms.

Abstract: A plurality of first rollers are rotatably mounted on a shaft symmetrically about the center of the shaft. The shaft is biased toward an axis about which a plurality of second rollers are mounted for rotation so that the first and second rollers contact each other. The shaft is supported for movement in a plane toward and away from the axis, and for rotation about an axis through the center of the shaft at right angles to the plane. A drive mechanism is provided for driving either the first or second rollers to forward a sheet between the nip of the rollers.

Abstract: A sheet feeding mechanism for a reproduction machine has a plurality of trays for supporting sheets of various sizes which are to be fed into the machine. A baffle plate is provided for each tray for guiding the sheets from that tray upwardly to a sheet separating roller assembly associated only with that particular tray. All of the sheets from the various trays are fed to a common output.
