Abstract

A gravity fed, "load-while-run" envelope feeder places a high capacity envelope storage bin's long dimension against a printer which creates a small footprint. The feeder transfers the envelopes from the storage bin to a horizontal transporation area with the rotation of a motor driven blade to within access of the printer's feed rollers. The blade catches an envelope's flap to feed it and rotates it by 90.degree. into the transportation area.
