<p>PURPOSE:To make it possible to accurately control a painting position in a height direction, by forming an air jet orifice for radially injecting an air stream toward the peripheral flange part of a rotary disc from the center part thereof along the lower surface of the rotary disc subjected to horizontal rotary drive. CONSTITUTION:A paint supply pipe 10 is provided to the center part of a metal rotary disc 1 subjected to horizontal rotary drive at a high speed and a knife edge 3 is formed to the peripheral flange part thereof. In this apparatus, the thin film of a paint is formed on the paint flow surface 4 of the disc 1 by rotary centrifugal force and the paint is scattered in a mist form toward the radius direction of the disc 1 by high voltage applied between the knife edge 3 and an object to be painted positioned at the lateral side of the disc 1 as well as the disc 1 is slowly driven upwardly and downwardly. By an air jet orifice 20 provided to the apparatus, an air jet stream is radially injected toward the peripheral flange part of the disc 1 from the center part thereof along the lower surface of the disc 1. Therefore, the flow of the paint scattered to a horizontal direction from the disc 1 is prevented from falling downwardly by gravity and a coating position can be controlled.</p> |
