Abstract

A rotary atomizing electrostatic coating apparatus includes a plurality of shaping air nozzles (6) disposed on a first circle having its circle center on an axis of rotation of an atomizing head (1), a plurality of pattern control air nozzles (7) disposed on a second circle having a larger diameter than the first circle. The pattern control air nozzles are located at 3-100 mm on a rear side of the shaping air nozzles (6) and inside a circle having a diameter three times a diameter of the atomizing head (1). An air passable opening may be formed radially between the shaping air nozzles (6) and the pattern control air nozzles (7).
