ABSTRACT:
The mechanism disclosed comprises a semi-automatic insertion machine for facilitating the insertion of contents into envelopes of the type utilizing exposed self-sealing adhesive.
The envelopes, with the seal flaps in open position and the adhesive exposed, are arranged in superposed relation within a supply hopper. Means is provided for removing the envelopes one by one from the supply hopper and transmitting them to the inserting station. The removal means for removing the envelopes from the supply hopper includes mechanisms for insuring that the envelopes shall not stick together due to the self-sealing adhesive, and for insuring that the envelopes shall be translated in one by one relationship to the inserting station.
At the inserting station the sidewalls of the envelope are drawn apart by suction gripping means, while the seal flap remains open and extended beneath a guide plate to facilitate the insertion of materials into the envelope by an operator.
After insertion, the envelope is again translated and during translation the seal flap is moved to closed position, and press sealed into place, and the envelope then translated to a receiving receptacle.
