ABSTRACT:
Apparatus for applying a coating to edges of envelopes. The envelopes are fed from a stack feeding device to a first conveyor which conveys them past a roller which applies the coating to one edge. A dead plate receives the envelopes from the first conveyor and feeds them to a second conveyor which is at right angles to the first conveyor. Applicator rollers are placed on opposite sides of the second conveyor to coat opposing edges of the envelopes.
