Abstract
An apparatus for the electrostatic application of a coating material in the form of a liquid to articles or the like comprising a nozzle at the region of which there are provided at least two electrodes at which there is applied high-voltage of the same polarity but of different magnitude. The electrical field between the electrodes covers the nozzle opening in the form of a transverse field.
Claims4
An apparatus for electrostatically applying coating materials to articles, comprising infeed means for delivering the coating material, means for the airless atomization of the coating material including a nozzle cooperating with said infeed means, an electrode arrangement to which there is applied high-voltage for electrically charging the coating material and for maintaining an electrical field for the transport of the charged material particles of the coating material to the article to be coated, said electrode arrangement comprising at least two electrodes arranged at the region of said nozzle having means connected thereto for applying a high-voltage of the same polarity but different magnitudes to said electrodes, said nozzle having a nozzle opening, and the electrical field between said electrodes covering said nozzle opening in the form of a transverse field, said electrodes comprising wires extending substantially parallel to the axis of the spraying jet of the coating material applied to the article, said wires possessing essentially the same spacing from said nozzle opening.
