ABSTRACT:
An elongate electrical conductor is continuously coated with electrostatically charged powder by passing the conductor upwardly through a tube into the upper portion of a container having a charged fluidized bed of the powder in a lower portion thereof. The tube extends upwardly through the bed and the tube height is adjusted relative to the upper surface of the bed to control the thickness of the powder coating. An array of electrodes having associated switches permits application of uniform coatings to conductors having a variety of shapes. Two or more conductors may be uniformly coated from the same fluidized bed in a container having a baffle which divides the upper portion into two or more compartments and spaced apart tubes extend upwardly into the different compartments.
