ABSTRACT:
A combination sheet-feed and utilization machine wherein the sheet feeder comprises an endless belt, or series of belts. The belt is driven in a path which is normally out of contact with a paper sheet stack and when a sheet is to be fed, the run of the belt between end supports is distended toward the sheet stack until contact is made and frictional engagement picks up the top sheet and begins it on its feed path. A retard mechanism prevents double feeding. The feed cycle is initiated by whatever means is convenient for the particular use, such as manual feed button or a machine cycle controller requesting another master, for example. The sheet travels to the utilization device, whatever type is being supplied, and when the sheet arrives at the utilization device in-feed, it triggers a sensor to initiate a circuit which ends the paper feed cycle and begins the utilization device cycle to pick up the paper from the feeder.
