  • Patent number: 5925419
    Abstract: In an electrostatic powder coating method of the present invention, a wheel is placed on a supporting jig and powder is electrostatically applied on the surface of the wheel. Unnecessary powder adhered on a tapered surface of a bolt hole is eliminated by suctioning the air inside the bolt hole through a suction opening of the supporting jig. Thereby, a coating film can be formed on the road wheel without applying a coating on the tapered surface of the bolt hole.

  • Patent number: 4898116
    Abstract: A powder coating booth a function of supplying air though its ceiling. Sidewalls of the booth is formed from an insulating material or a semiconductor. A belt conveyor is disposed at the bottom of the booth. An electric field is formed so that it extends from a paint gun to the conveyor belt. The majority of oversprayed powder paint produced during painting becomes attached to the upper surface of a portion of the conveyor belt, is carried, together with this belt portion, to the outside of the booth, and is recovered from the conveyor by a blowing-type of static eliminator, thereby minimizing the mount of oversprayed powder paint mixed in an exhaust of the booth drawn through the sidewall.
