Abstract:
1. An apparatus for adjusting a position of a movable envelope stopper in an inserting area of an envelope insertion machine, wherein the inserting area has an upstream end and an downstream end, and the envelope stopper is positioned between the upstream end and the downstream end for stopping an envelope fed from the upstream end towards the downstream end along a feeding direction in order to place the envelope at a desired location for mail insertion, and wherein the envelope has a size and an edge, and the position of the envelope stopper is adjusted according to the size of the envelope so that the edge of the envelope is substantially aligned with the envelope stopper when the envelope is stopped, said apparatus comprising: a movable sensing device, coupled in a fixed relative position to the movable envelope stopper, adapted to sense the edge of the envelope when the envelope is placed at the desired location; and at least one or more servo motors for moving the sensing device and the envelope stopper along the feeding direction and for placing the envelope stopper when the sensing device senses the edge of the envelope.
