Envelope Stuffing Device An envelope stuffing device in which no moving parts are required for opening the mouth of an envelope for the insertion of inserts therein. The stuffing device has a plurality of leaf springs, two of which are adjacent the ends of an envelope and are located directly above openings within a floor of the device. Other leaf springs are located intermediate the ends of an envelope, so that when the flap of the envelope is in registration with the leaf springs, the outer leaf springs push down on the end of the envelope and the intermediate leaf springs hold the flap on the floor, thereby causing the mouth of the envelope to open. The device includes a conveying mechanism for placing inserts into to envelope when the mouth of the envelope is open.
