Jam tolerant mail inserter

摘要

In a mailing machine where an envelope feeder is used to feed envelopes (90) one at a time into a mail inserter and an insert feeder is used to move insert material (80) into the envelope in the mail inserter for mail insertion, a suction cup assembly (200) having two suction cups (210) is used to keep the throat (98) of the envelope in the mail inserter open. Each suction cup (210) is movably mounted on an air actuated holder so as to allow the suction cup to move up and down to open the envelope throat (98). The suction cup assembly (200) is movably mounted on a mounting stand in the mail feeder at a pivot (124) so that the suction assembly can be rotated at the pivot (124) so as to deflect the suction cups further away from the insert feeder if a jam involving the insert material or the envelope occurs.
