ABSTRACT:
A moistener for stamps and envelopes is provided which includes a durable metal roller providing even water flow across the roller. The roller is made for continuous use with water for the purpose of moistening a layer of dried glue, which has been previously applied on envelopes, stamps, dried glued labels, and other materials which are used for adhesion in mail related objects. The roller includes a specific knurling pattern for a uniform flow of a thin layer of water across the roller. By the knurled pattern, a series of tiny water pockets are formed. Water transferred from a reservoir to the roller during rotation of the roller is held within these tiny pockets and the water, due to surface tension, extends between adjacent pockets and above diamond-shaped projections to produce a thin film of water protruding above the uppermost peripheral surface of the roller.
