摘要： Disclosed herein is a method of paint application. This method has the following advantageous effects. More specifically, when different paint is used, desired paint is alternately supplied to a first paint feeder and a second paint feeder from a paint feed source thereby to enable efficient painting of a workpiece by a spray gun. On the other hand, when the same paint is used, the paint is supplied only to the first paint feeder without using the second paint feeder, thereby making it possible to reduce wastefully-discharged paint and to efficiently carry out any cleaning work.

摘要： 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.

摘要： Disclosed herein is a structure for preventing current from leaking out of devices such as a valve, an intermediate reservoir, etc., which are employed in an electrostatic spray coating apparatus for applying a desired voltage to electrically conductive paint so as to electrostatically spray-coat a workpiece therewith. The current-leakage prevention structure basically comprises any one of the devices each made of an electrically-conductive material, a container made of an insulating material, which accommodates the device therein and has a paint passage defined therein capable of communicating with the device, and a cover for externally covering the container. A creepage distance defined by the container and the cover is set to reach a desired creepage length or more capable of preventing current leakage. It is therefore possible to reliably prevent current from leaking even when a high voltage is applied to the devices.
