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.

Method and apparatus for feeding documents

An improved document feed mechanism for feeding documents in a vertical direction through at least two stations including a device for shingling the documents in at least one station by having successive ones of the documents overlap one another to thereby compress the amount of vertical space required for the feeding operation as opposed to the space that would be required if the documents were fed top edge to bottom edge, respectively.
