Ejection mechanism for envelope inserting machine

In an envelope inserting machine having means for feeding envelopes seriatim in one direction along a feed path to and through an inserting station, means for incrementally moving the envelopes in the reverse direction through the inserting station until they reach an insert receiving position, means disposed at said inserting station for opening the throats of the envelopes when the they are at the insert receiving position to permit insert material to be inserted into the envelopes by an inserting mechanism, and means for driving said throat opening means through successive cycles of operation in synchronism with the reverse direction incremental movement of the envelopes to the insert receiving position, an envelope ejecting mechanism for ejecting envelopes from the inserting machine, said envelope ejecting mechanism comprising:

• A. means for ejecting the envelopes from the insert receiving position after the insert material has been inserted thereinto,
• B. means connecting said envelope ejecting means to said means for driving said throat opening means and said means for incrementally moving said envelopes in said reverse direction, and
• C. control means operatively interconnected between said envelope throat opening means and said envelope ejecting means for preventing said envelope ejecting means from ejecting an envelope until it is positioned at said insert receiving position and insert material has been inserted thereinto,
• whereby said envelope ejecting means is driven in synchronism with the operation of said envelope throat opening means and the incremental reverse movement of the envelopes to the insert receiving position to prevent envelopes from being ejected prior to insert material being inserted thereinto.
