Abstract
Document feeding apparatus advances the leading document in a stack of documents against a moveable feed element which moves at a predetermined, load sensitive speed. The torque applied to the leading document by the feed element is maintained at a substantially constant level by sensing the speed of the moveable feed element and electronically controlling the pressure applied by the stack of documents against the moveable feed element in order to maintain the torque applied by the moveable feed element to the leading document of the stack at a substantially constant value.
