For example, the spray area a shown in FIG. 1 (a) when spraying is applied to the part stretched over the rollers), but in the present invention, the spray nozzle is the apex, and one spray direction is taken as the reference. Since an elliptical cone spray having an angle θ in the main scanning direction and an angle T in the sub-scanning direction is used, the spray area forms a circle.

る。In addition, the final scanning line interval, ie, the spray interval (hereinafter referred to as linear density) is the final scanning line interval, and the uniformity of the coating can be changed by adjusting the spray area a and the linear density to optimally overlap the spray area. . By using an elliptical cone spray as in the present invention, the degree of overlapping increases and the occurrence of unevenness is suppressed, and in spray coating on a commonly used cylindrical substrate, it is possible to use a spray droplet in the main scanning direction where the adhering section is long. The long sleeve of the spray inertia cone has a short adhesion section,
By allocating the short axis in the sub-scanning direction, where the spray droplets detach from the adhesion area and generate a large amount of particles, it prevents irregularities on the coated surface and coating loss due to redeposition, and furthermore, the area covered by the spray is long. By doing so, at least the main scanning speed can be increased, and therefore the coating time can be shortened.
