Abstract
An electrostatic spray coating apparatus having a spray nozzle which has a spray orifice for atomizing coating material. The nozzle orifice may be round or, preferably, is in the form of a slot to impart a flat shape to the atomized material. The spray nozzle is mounted to be rotated on a body of the spray gun so that the atomized material particles are driven radially outwards in addition to the forward direction and are thereby distributed uniformly in the cloud of sprayed material. A brake may be provided to slow down the rotation when greater penetration into cavities in the article being painted is desired. In invention may be used in either power spray coating apparatus or liquid spray coating apparatus.
