ABSTRACT:
In a high speed mail sorting machine, a mechanism for feeding envelopes one at a time to a pickoff device such as a vacuum belt system. The envelopes are loaded onto a floor panel which inclines from side to side. A chain conveyor moves the envelope supply along the floor panel with each envelope having its lower edge traveling on the floor and one side edge travelling along an inclined side panel. The envelopes are successively discharged from the inclined floor onto a conveyor belt which is driven transversely to the floor and at a greater speed than the chain conveyor. The speed difference causes the envelopes to spread out as they travel downstream. The conveyor belt loads the envelopes onto a driven roller having a spiral groove which feeds the individual envelopes flatly against the vacuum belts of the envelope pickoff device.
