Electrostatic powder-coating method, whereby a flat fan-spray of electrically charged powder particles is directed toward an object to be coated, said spray being formed from an incident stream consisting of a mixture of powder and carrier-gas, comprising means for re-homogenizing said incident stream, means for subsequently deflecting said stream in a direction substantially perpendicular to its incident direction, means for thereafter driving said stream against the internal walls of a duct designed to convert said stream into a fan-shaped spray, and means for electrically charging the powder particles of the said spray. The re-homogenizing means may, however, be omitted in certain cases.
