Abstract
A sheet feeding device for separating a single sheet from a stack of sheets and forwarding the separated sheet away from the stack is disclosed which employs an endless friction belt cantilevered about a drive pulley such that the unsupported end of the belt floats freely on a stack of documents or paper sheets when the belt is in the feeding position. As the belt is driven about the pulley the unsupported end of the belt pulls and advances the foremost sheet from the stack and advances it over a retard member on which the unsupported end of the belt also floats. Because the belt floats freely on the stack of sheets, the normal force is evenly distributed over the surface of the belt, intersheet coupling is minimized, and the belt is able to conform to changes in the paper and stack condition.
