ABSTRACT:
A method and apparatus for electrostatically spray coating substrates with layers of material having uniform thicknesses is provided. A substrate to be coated is electrically grounded and an electrically charged, atomized spray of coating material is directed toward the substrate from a nozzle. The nozzle is traversed along a length of the substrate, which can also be rotated, to coat substantially the entire surface of the substrate. In order to compensate for thickness variations in the applied coating, the speed of traversal of the nozzle is varied. In a preferred embodiment, where photoreceptor drums are produced by spraying a photoreceptor material onto a cylindrical substrate, the speed of traversal of the nozzle is reduced as it approaches at least one end of the cylindrical substrate.
