Abstract
A method and system is disclosed in which an article, having large open areas or a multiplicity of apertures, is dip coated. The method and system is particularly adapted for use in coating a grid of a corona charging device utilized in the xerographic process. A transport system immerses and removes the article from a tank storing coating material. An unwanted coating material is created across the apertures of the article. Thereafter, the transport system moves the article past an ultrasonic wave source. The impact of the ultrasonic energy transmitted to the unwanted coating material across the apertures causes the removal thereof. The removed coating material is returned to the coating material in which the article was immersed.
