Semi-automatic insertion machine for envelopes
First Claim
1. A machine for facilitating the manual insertion of materials by an operator into envelopes of the type having a body and an adjacent seal flap provided with exposed self-sealing adhesive, said machine comprising:
- a hopper for receiving a quantity of envelopes and including means normally supporting the envelopes in stacked relation with the envelope seal flaps in superposed extended position, means for withdrawing envelopes in one by one relationship from the hopper, means independent of said normal stack supporting means and separately engageable with the envelope stack as additional support therefor for inhibiting removal of remaining envelopes in the hopper as each envelope is withdrawn, an inserter station, means for translating each envelope withdrawn from the hopper to the inserter station, means at the inserter station for separating the envelope side walls to facilitate the introduction of materials into the envelope, a guide plate at the inserter station for guiding materials into the envelope, translating means for removing a filled envelope from the inserter station, and flap closing means operable upoh the filled envelope for sealing the flap onto the adjacent envelope side wall.

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.

9. A machine for facilitating the manual insertion of materials by an operator into envelopes of the type having a body and a normally open extending seal flap, said machine comprising:
- a hopper for receiving a quantity of envelopes and including means normally supporting the envelopes in stacked relation with the envelope seal flaps in superposed extended position, means for withdrawing envelopes in one by one relationship from the hopper, means independent of said normal stack supporting means and movable into additional stack supporting position engaging the next adjacent envelope in the stack during each one by one envelope withdrawal from the stack, an inserter station having an inserter guide plate, translating means for translating each withdrawn envelope from the hopper in substantially horizontal disposition to bring the extended seal flap into position beneath the guide plate, means at the guide plate station to separate the envelope side walls to facilitate the introduction of materials across the face of the guide plate into the envelope, translating means for removing the filled envelope from the guide plate station, and flap closing means for closing the envelope flap upon operation of said last named translating means.
