摘要： A rotating spraying type coating apparatus having a spraying head attached to a rotating shaft of a rotating drive device, a paint supply passage connected to the proximal end of the spraying head, and a paint radiating portion formed at the distal end of the spraying head to thereby spray paint particles from the paint radiating portion. The apparatus is provided with a partition member which is disposed around the outer periphery of the spraying head in opposing relation to the latter, and at least a pair of air outlet ports which are disposed in such a manner that air is jetted out forwardly from the air outlet ports toward the outer peripheral surface of the partition member. Thus, the direction of spray of paint particles from the paint radiating portion is controlled by means of the jetted air, and it is possible to obtain elliptical and dumbbell-shaped spray patterns which cannot be obtained by the conventional rotating spraying type coating apparatuses.
