ELECTROSTATIC COATING METHOD AND APPARATUS FOR THE SAME

摘要

Disclosed is an electrostatic coating method using a paint cartridge. Whe n paint feeding passages (68 and 88) are rinsed with a liquid fed from a pai nt feeding unit (20), the liquid is fed from the paint feeding unit to a res ervoir unit (13) and reserved therein. Next, the liquid in the reservoir uni t is fed via a fluid circuit (10A) to a fluid chamber (83) in a paint cartri dge (19). The liquid in the fluid chamber extrudes conductive paint in a pai nt chamber (84) through a free piston (82), thereby to feed a coating gun (1 4) with the conductive paint.
