  • Electrostatic powder coating method and apparatus therefor
    Patent number: 4917917
    Abstract: An electrostatic powder coating method and apparatus therefor, in which an auxiliary electrode is disposed in the vicinity of a desired coating surface of an object to be coated, a gun for performing electrostatic powder coating is directed to the object to be coated and the auxiliary electrode, a DC electric field is formed between the gun, the auxiliary electrode and the object to be coated, the auxiliary electrode is electrically charged to the same polarity as the gun so as to form an auxiliary electric field between the auxiliary electrode and the desired coating surface of the object to be coated whereby a powder coating material is transferred to be applied onto the desired coating surface by the electric field.
    Type: Grant
    Filed: November 28, 1988
    Date of Patent: April 17, 1990
    Assignee: Onoda Cement Company, Ltd.
    Inventors: Masahiro Yamamoto, Mituyosi Kumata, Katutoshi Kozoe, Tsutomu Itoh
  • Electrostatic powder coating apparatus
    Patent number: 4811689
    Abstract: An electrostatical powder coating method and apparatus therefor, in which an auxiliary electrode is disposed in the vicinity of a desired coating surface of an object to be coated, a gun for performing electrostatically powder coating is directed to the object to be coated and the auxiliary electrode, a DC electric field is formed between the gun, the auxiliary electrode and the object to be coated, the auxiliary electrode is electrically charged to the same polarity as the gun so as to form an auxiliary electric field between the auxiliary electrode and the desired coating surface of the object to be coated whereby a powder coating material is transferred to be applied onto the desired coating surface by the electric field.
