Abstract: Workpieces are electrostatically coated with powder materials. It is possible to attain a relatively large coating thickness in a single operation by simultaneously or alternately coating with powder particles that have a different electrical charge. The process can be used in applying single-component or multi-component coating materials.

Abstract: The invention relates to a device for the powder-dusting of moving objects, particularly flat substrates in the form of webs and sheets of paper, plastic or textile with a nozzle housing made of electrically insulating material, with at least one nozzle provided on the housing for releasing a powder air stream laden with dusting powder and with metallic electrodes and counter-electrodes disposed on the housing for producing an electrical high-voltage field. To obtain a powder air stream with powder particles as neutral as possible, it is envisaged that at least one electrode and a counter-electrode cooperating with the latter are disposed on the outside of the housing in the vicinity of the nozzle whereby an electrical high AC voltage is applied to the electrode and counter-electrode, whereby, after being released from the nozzle, the powder air stream penetrates the thus produced high AC voltage field on the outside of the housing.

Abstract: An electrodynamic spray painting system having a spray gun (13) for spraying paint toward a workpiece (15) and an electrode (16) for causing a charge to be imposed on the paint. A high voltage waveform generator (21) supplies an oscillating voltage to said electrode (16) such that coronas of varying strengths are periodically, controllably generated.This oscillating voltage enhances the spectrum of charges on the paint particles improving evenness of coverage of paint on the workpiece (15). Additionally, wastage of paint is decreased. This invention is also applicable to other coating materials, such as powders.

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.
