Abstract
An apparatus and method is disclosed for inserting sheet material into a quantity of envelopes. The envelopes are conveyed in seriatim along a conveyor to an indexing drum. The envelopes are shingled and respectively overlap each other as they approach the drum. The indexing drum simultaneously receives one envelope from the conveyor, while discharging another envelope to an inserting deck. Each discharged envelope is restrained, and then sheet material is inserted therein. A sensor disposed upon the inserting deck, respectively senses each discharged envelope and provides a signal to actuate the inserting mechanism, and deactuate the indexing drive. When an inserted envelope leaves the deck, the sensor then actuates the indexing drive to cause the drum to discharge another envelope.
