ABSTRACT:
A friction retard feeder adapted to feed sheets from a stack into a paper path located in a horizontal plane includes a tray which holds a stack of sheets at an angle of between 15.degree. and 20.degree. with respect to the paper path. A paddle wheel having a plurality of blades is positioned a predetermined distance in front of sheets stacked in the tray so that as the paddle wheel is rotated the blades in a first position strike the top sheet in the stack in a plane parallel to the top of the stack and separates it from the remaining sheets in the stack. Continued rotation of the paddle wheel causes the blades to deflect downward in front of the stack and thereby inhibit movement of sheets other than the top sheet from the stack. The tray also includes a high friction surfaced pad that cooperates with the paddle wheel in order to enhance the feeding of sheets near the bottom of the tray.
