ABSTRACT:
This invention relates to a device for moistening envelope flaps, comprising a reservoir of liquid, means for pumping this liquid and, disposed transversely with respect to a direction of advance of the envelopes and inclined with respect to a horizontal plane for supporting these envelopes, means for spraying on the envelope flaps a part of the liquid pumped from the reservoir of liquid. This inclination of the spray means corresponds to the angle of inclination of the flaps of envelopes with folded down flaps.
