Abstract

PURPOSE: To prevent the adhesion of paint to the surface not to be painted, when the parts to be painted is immersed in the paint and is painted, by blasting the gas against the neighborhood of unpainted face of the parts to be painted positioning at the free surface of the paint, any by immersing the parts in the paint while above blasted air is depressing the surface of the paint.

CONSTITUTION: The parts 25 to be painted is put between the holders 15, 21, and the valve 28 is opened in order to supply the compressed air to the containers 26, 33, through the hoses 30, 35. When the pressure of both containers 26, 33, goes up, the compressed air radially spouts out of both containers 26, 33, passing through gaps 27, 34, and flows along the end face 25a of the parts 25 depending on the side wall adhesion phenomenon (Coanda effect). Then, the parts 25 is rotated by the motor 14 and the movable support plate 6 is moved down to a position where the nut 12 strikes against the stationary support plate 3; hereby, the bottom end of parts 25 is immersed in the paint 24. The compressed air flowing along the end face 25a is blasted against the paint existing near the end face 25a; hereby, the surface of the paint is depressed as shown by the broken line so that the paint 24 does not adhere to the end face 25a.
