Water supplying device for envelope flap moistener, has water reservoir disposed in receptacle that is movable between bottom and top positions corresponding to low and high level of water in water reservoir, respectively

摘要

The device has a water reservoir (10) from which water flows across a communication duct (14) to water reservoir (18), where the quantity of the water permeates a foam or sponge (16) soaked in a water reservoir (18). The reservoir (18) is disposed under a transport horizontal plane of envelopes across a mail processing machine. The reservoir (10) is disposed in a receptacle (26) that is movable between bottom and top positions corresponding to the low and high level of water in the reservoir (10), respectively.
