ABSTRACT:
A multi-ream paper sheet feeder for use with high speed copiers, printing machines and the like "host machines" has a sturdy frame supporting an upwardly sloping ramp overlying a motor driven feed screw. A pusher plate drives a feed block of as many as thirty reams of edgewise stacked paper sheets up the ramp to a singulating feed assembly. A feed screw drive nut carriage engages and drives the pusher plate up ramp, then disengages, retracts under the ramp and travels to a new start position at the ramp's lower end. Sensors and limit switches govern forward and reverse feed screw motor operation; another sensor governs the operation of the singulating feed assembly, delivering shingled sheets on demand to the feeder's infeed tray. The entire sheet feeder is track-mounted, latched in feed position, disengageable for retraction away from the host machine when desired.
