ABSTRACT:
A herein is a method of and an apparatus for electrostatically spray-coating a workpiece with electrically-conductive paint. The workpiece is first sprayed with the paint directly subjected to a high voltage from a rotatable atomizing type spray gun so as to electrostatically coat the work with the paint. Thereafter, cleaning liquid is supplied to a rotatable atomizing head through a line for washing after completion of the electrostatic spray coating process so as to clean the rotatable atomizing head. Further, after the rotatable atomizing head has been washed, the line is dried, and the next electrostatic spray coating process is carried out after the line has been dried. The spray gun includes an inner line as a path, for supplying the paint to the rotatable atomizing head, and an outer line as a path used for washing, for supplying the cleaning liquid used to wash the rotatable atomizing head. The inner line oriented toward the rotatable atomizing head has a terminal which projects forward from a terminal of the outer line.
