ABSTRACT:
An envelope contents extraction system in which adjacent edges of an envelope are opened to make the contents of the envelope accessible from two edges. The stations at which the envelope edges are opened and the contents removed are located along a single straight-line path. The envelopes are delivered to these stations by a straight-line conveyor which receives the envelopes and moves in one direction to move the envelopes to a side edge cutter and then in the opposite direction to move the envelope to a top edge cutter and an envelope spreader.
