A method and apparatus for staging envelopes in a mail insertion machine. In the mail insertion machine, envelopes are moved into an envelope inserting area one at a time with the flap of the envelopes trailing the envelope bottom edge and flipped away so as to allow enclosure material to be inserted into the envelope. While one envelope is paused in the envelope inserting area for receiving enclosure material, the next envelope is moved towards the envelope inserting area such that the flap of the paused envelope in the envelope inserting area is partially overlapped with the next envelope in a shingling fashion. In order to properly separate these envelopes, a sensing device is used to sense the arrival of the bottom edge of the next envelope in order to control the further movement of the next envelope.
