ABSTRACT:
An apparatus for moistening the gummed section of an envelope flap for the purpose of sealing the flap to the body of the envelope, is disclosed. The apparatus comprises a reservoir containing a moistening fluid. An endless belt movably conveys the moistening fluid from the reservoir past a window. A bead chain apparatus projects through the window to obtain the moisture carried by the moving belt. An envelope with a distended flap is caused to move past the bead chain apparatus, causing the envelope flap to be wetted thereby. The bead chain apparatus comprises a snap-in frame, which is easily assembled to the moistening apparatus. When a frame becomes laidened with gum residues, it is removed, and a new frame, supporting fresh moistener beads, is snapped into place.
