Abstract

A moisture control system for a contact roller-type fluid applicator automatically maintains the fluid level on the roller surface within a predetermined range. A sensor biased against the roller continuously monitors the moisture content and signals an electronic controller to initiate sequential wetting and delay cycles when it is below a preset value.
