Abstract: A method and apparatus for electrostatically applying solid particles to an article employs a nozzle forming the solid particles into a pattern and directing them at the article, preferably in a relatively flat, fanlike spray. The forward portion of the nozzle is formed of insulating material and includes an ionizing electrode. An electrostatic field is established between the article and an electrode that creates a single highly ionized zone offset from and rearwardly of the spray. The percentage of solid particles which are sprayed but remain undeposited is reduced using this method and apparatus.
