Abstract: An electrode and method for electrostatically treating the surface of a substrate of continuous sheet metal material, wherein the electrode comprises a rotatable, electrically conductive cylindrical member onto and off of a segmental portion of the peripheral surface of which the substrate is continuously wrapped. The cylindrical member has its peripheral surface encompassed by a non-conductive material for engaging the substrate as it passes around the cylindrical member. The nonconductive material includes an insulating barrier for insulating the substrate from the cylindrical member, and outwardly opening cavities to provide an air space between the substrate and the cylindrical member, in the area of the substrate wrapped on the cylindrical member, to enable ionization of the air in such air space for treating the substrate surface wrapped on the cylindrical member upon application of a potential difference between the cylindrical member and the substrate.
