Abstract
A method for opening an envelope for insertion of a collation in an envelope inserting machine. The envelope is fed into an inserting station with its flap in an open position. The insertion station has vacuum belts to hold the envelope in position, and to move the envelope in an upstream or downstream direction. A suction cup is positioned above the envelope in the insertion station. The suction cup is moved downward to engage a top surface of the envelope near an upstream edge of the top surface. The suction cup then lifts the top surface of the envelope to open a throat of the envelope to facilitate insertion of a collation. The envelope on the vacuum belt is then moved in the upstream direction by a small amount so that the top surface of the envelope forms a more open angle for receiving the collation.
