Abstract
An electrostatic atomizing coating apparatus and method incorporate a rotary head having a base portion, an open end and a plurality of grooves formed radially on an inner peripheral surface of the open end, an inside diameter of the rotary head increasing from the base portion toward the open end, and a motor configured to rotate the rotary head to discharge a thread-shaped paint. A voltage is applied to the rotary head so as to form an electrostatic field between the open end of the rotary head and an earthed coating target and to electrostatically atomize the thread-shaped paint discharged from the open end. Voltage output from the generator is controlled so as to adjust an intensity of the electrostatic field and to control a particle diameter of the electrostatically atomized thread-shaped paint.
