Abstract: A method of electrostatically coating an article (35) with paint includes projecting the paint from a gun nozzle (33) in a plurality of atomized particles, establishing an electric field (32) between an electrode (29) and the nozzle (33) sufficient for imparting an electric charge of one polarity to the particles at the nozzle (33), and establishing a zone of ions (80) in the pathway of the particles for neutralizing and reversing the polarity of a portion of the charged particles eminating from the nozzle (33). The plurality of diversely charged particles are attracted to the electrically charged article (35) along different individual paths in order to more uniformly paint irregular surfaces.

Date July 9, 1981In electrostatic coating apparatus, a conveyor supporting a carrier having workpiece-support suspension means attached thereto. The carrier includes a rail member, a pair of electrically insulative sleeve members adjustably slidable on said rail, a metallic tubular member having an electrical contact thereon mounted on each sleeve, and the suspension means attached to the tubular members.

Abstract: A system and method for electrostatic coating of articles with paint particularly suited for coating irregular surfaces from a substantial distance. Water-borne conductive paint may be handled from an electrically grounded supply. Plural paint particle charging mechanisms are established by a DC potential applied to an electrode physically divorced from the paint stream. The articles being coated are electrically charged.

Abstract: An electrostatic coating system in which the workpiece to be coated is charged to a high DC potential. A conveyor moves the workpiece through a coating zone. A separate charge collector disc on the workpiece support passes close to but does not contact a charged conductor. An electrostatic charge is induced on the disc and is transferred to the workpiece. The conveyor is grounded and the workpiece support is connected to the conveyor through a high resistance which completes the charging circuit and drains the charge from the workpiece and support as they leave the coating zone. The ends of the charged conductor are curved away from the path of the charge collector. Insulating plates shield the conductor and limit swinging of the workpiece support.
