<p>A rotary spray head coater such that paint adhering to the edge of the outer circumferential surface (13H) of a bell cup (13) is removed completely. The bell cup (13) has a thinner passage (18) for communication of the outer circumferential surface (13H) with the paint reservoir (17) of the bell cup (13). Through the thinner passage (18), the thinner flowing out on the outer circumferential surface (13H) of the bell cup (13) is introduced to its discharge edge (13D). For the introduction, assist air jet outlets (30) through which assist air is jetted out are provided inside shaping air jet outlets (4) on the edge surface (3A) of a shaping air ring (3). Therefore, at the time of cleaning, the thinner flowing out on the outer circumferential surface (13H) is pressed against the outer circumferential surface (13H) of the bell cup (13) by the assist air and the shaping air and introduced to the end side of the bell cup (13) to remove the adhering paint. <IMAGE></p> |
