    • PROBLEM TO BE SOLVED: To prevent a coating material from stirring up from a gap between a coater and an opening without using a shaping air when cleaning the coater by rotating a rotary atomizing head at high-velocity revolution while feeding a thinner to the coater in inside of a cleaning hopper. SOLUTION: In cleaning the rotary atomization type coater T while feeding the thinner, the rotary atomizing head B is inserted from an opening 3 formed on the upper surface of a hopper housing 2. Inside of the coater cleaning hopper 1 for atomizing a residual coating material and thinner inside, an air stream control member 4 is positioned at the lower part of the rotary atomizing head B corresponding with the gap G between the coater T and the opening 3, for blocking the stream rising toward the outside of the housing 2 through the gap G between the coater T and the opening 3 from the inside of the housing 2 followed by the rotation of the rotary atomizing head B. In the air stream control member 4, a vent hole 5 is formed for supplying air to a negative pressure part 6 generated directly bellow the rotary atomizing head B. COPYRIGHT: (C)2006,JPO&NCIPI
