An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is transferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor. During the subsequent pass of the article through the coating zone, the uncoated surface of the article is then covered with powder which is subsequently cured during the second pass of the article through the curing zone. The second coating step for the article may be accomplished by passing the article through the same apparatus as for the first step or by passing the article through a second identical apparatus. |
