Abstract
An electrostatic coating facility for an electroconductive coating material comprising a coating machine disposed in a coating zone while being grounded to the earth, an insulated conveyer disposed in the coating zone for conveying an object to be coated in an electrically insulated state and applying a high voltage to the object, an entering conveyer disposed for carrying the object into the coating zone, a delivery conveyer for carrying the coated object out of the coating zone, and a relay transfer device interposed between the insulated conveyer 1 and the entering conveyer or the delivery conveyer for transferring the object in an electrically insulated state while keeping a required insulation distance between each of them. Aqueous coating material free from public pollution can be used with no troubles for taking insulative measures on the side of the coating machine and without worry of spark discharge.
