Title:
METHOD AND APPARATUS FOR ELECTROSTATIC COATING OF POWDER
Document Type and Number:
Japanese Patent JPS52127949
Kind Code:
A
Abstract:
A pulsed powder application system for electrostatically powder-coating a substrate comprises an applicator bed means, a fluidizing means, and a pulsing means. The pulsing means is actuable during a coating time to effect ionization of electrostatic powder particles so as to cause the establishment of an electric field attracting the particles to the substrate, and actuable during non-coating times to cause the establishment of a reverse electric field attracting the ionized particles away from the substrate. A feeder bed means and an associated fluidizing means are provided for holding the electrostatic powder prior to usage for coating by the applicator bed means.
