Abstract
A rotary atomizing electrostatic coating apparatus having a rotating spray head, and a paint nozzle for feeding paint on the front surface of the spray head, in which the spray head is comprising a spray head main body made of an electrically insulating material, and a plurality of discharge electrodes having nearly band-form pattern extending outward approximately along the rear side shape of the spray head main body from the central side of the spray head main body with a mutual phase difference or extending symmetrically about the axis of rotation of the spray head main body. The plurality of discharge electrodes rotate together with the spray head main body, and the discharge current in the front side direction of the axis of rotation of the spray head is made uniform and increased, thereby enhancing the painting efficiency.
