Apparatus for effecting controlled and accurate moistening of an object is described. A hollow rotor is provided with at least one shaped portion in its surface, that portion having a row of nozzles therein. The nozzles are drilled completely through the rotor sidewall so that they comprise a conduit between the rotor's center and the outer surface of the rotor. An apertured plate and shutter plate are movably mounted between an object to be coated and the rotor. Fluid is delivered to the center of the rotor from a supply thereof by means of an inlet tube. The rotor is coupled at its other end, which is sealed to prevent fluid escape, to a motor and driven thereby to eject fluid from the nozzles, aided by the vacuum effect of the shaped rotor portion. Only that fluid escaping through the exposed section of the slot in the apertured plate strikes and thereby coats the object to be moistened. Movement of the shutter plate can be used to incrementally adjust the width and number of layers of fluid applied to the moistened object.
