う欠点があった。However, in the conventional technology, firstly, the wire diameter of the linear body is much smaller than the coating turn width of the sprayer, so the coating efficiency is very low. was there. Second, if the coating agent particles do not fly at right angles toward the linear body, the coating agent particles will scatter toward the inner wall surface of the coating booth, causing a mess inside the coating booth. However, there was a drawback that it was difficult to recover the wasted coating agent. Thirdly, in the conventional technology, in order to obtain a uniform coating width around the entire circumference of the linear body, it is necessary to install multiple sprayers in the coating booth, and the equipment is It had the disadvantage of being complicated and large.
