VERIFICATION OF OPERABILITY OF MOISTENER

A moistening arrangement for moistening a flap of an envelope has a nozzle directed to spray a liquid at the envelope flap along a given locus in the plane in response to signals that are a function of the width of the flap for moistening the flap at determined positions thereof. A sensor is positio...

Summary:A moistening arrangement for moistening a flap of an envelope has a nozzle directed to spray a liquid at the envelope flap along a given locus in the plane in response to signals that are a function of the width of the flap for moistening the flap at determined positions thereof. A sensor is positioned to detect the presence of liquid emitted from the nozzle. A control arrangment controls application of liquid to the nozzle while an envelope is adjacent thereto, and liquid is momentarily directed to the nozzle prior to movement of an envelope adjacent to the nozzle for providing an indication of operability of the nozzle and liquid applying arrangement.
