<p>PURPOSE:To attain to enhance painting efficiency, by a method wherein a cylinder is coaxially arranged to the outer periphery of the leading part of a rotor and the knife edge part of the cylinder is forwardly protruded from the opening part of the emitting orifice of the rotor. CONSTITUTION:A disc like base body 11 is integrally provided to the rearward inner peripheral surface of a rotor 2 while a rotary shaft 8 is protruded from the center of the rear surface of the base body 11 and the rear end of the rotary shaft 8 is connected to the output shaft 9a of an air motor 9. To the inner peripheral surface of the leading end part of the rotor 2, a ring like protruded wall 14 is integrally formed and a paint emitting orifices 1...piercing the front and the rear surface thereof are provided to the protruded wall 14 by drilling. In addition, a cylinder 4 is provided to the outer periphery of the front part of the rotor 2 in an inlaid state and the inner peripheral surface of the leading part of the cylinder 4 is formed into a tapered shape of which the diameter is enlarged forwardly while the peripheral flange of the leading end of the cylinder 4 is sharpened to form a knife edge part 3.</p> |
