Abstract
Documents in a stack are loaded into a bin from which an endmost document is fed by some means to a generally cylindrical drum having a high friction surface which is rotationally driven about its cylindrical axis. A plurality of resilient continuous stretchable friction belts of lower friction than the high friction drum surface are arranged parallel to one another around pulley supports positioned such that non-friction circumferential areas around cylindrical drum surface stretch the path of the continuous belts between adjacent pulleys. The continuous belts are driven in the opposite direction from the high friction cylindrical surface of the drum. The opposed moving surfaces separate adjacent sheets while the belts apply a normal pressure to a document on the high friction surface so that it draws the endmost document from the stack and carries the separated single document through the mechanism by itself.
