ABSTRACT:
An insertion machine includes an insertion station (44) whereat groups of items are stuffed into an envelope held open at an envelope opening station (49). The insertion station comprises a cam (212)-driven carriage (202) which linearly reciprocates in a direction (480) toward and away from the envelope opening station (49). The carriage (202) carries a plurality of selectively mounted, selectively rotatable pusher fingers (204). The pusher fingers (204) have a profile suitable for shoving items along a partially inclined insertion plate surface 403 and into an opened envelope. The pusher fingers (204) are selectively rotatable to an operative orientation (720) and to an inoperative orientation (722) under the supervision of a controller (205). Jam detectors (550, 552) are provided proximate reciprocating entry flanges (500, 502) which move when a jam occurs in the inserting process. Should a jam occur, the pusher fingers (204) are controlled to rotate the their inoperative orientation (722). Access to the jam location is obtained by rotating the carriage (202) about an axis (415) and by swinging an envelope opening gate (660) about another axis (662). After the inserting of a group of items into an envelope, a flap moistener (70) detects a change in electromagnetic flux as the result of the travel of an opened envelope flap and sprays an atomized fluid along spaced-apart paths (699A, 699B) onto gummed regions of the envelope flap.
