PURPOSE:To enable uniform coating in a stage of forming a layer of laminated liquid films on a travelling base body by forming the liquid films by falling down the liquid films freely and vertically from an end of an inclined slide face wherein the viscosity of the liquid for the lowermost layer, and the uppermost layer, and the ratio of the viscosities of liquids for two adjacent laminated layers to each other are regulated to specified values. CONSTITUTION:At least two liquid layers are laminated on an inclined surface of a slide and fallen vertically from a canopy top at an end of the slide and a laminated liquid layer film formed by the free falling of the liquid is landed on a travelling base body to form thus a laminated film layer. In this state, the viscosity of the liquid for forming the lowermost layer 2 and the uppermost layer 1 are regulated respectively to >=40cP and <=30cP, and the ratio of viscosities of the liquid for the adjacent two laminated layers to each other is regulated to <=2 basing on the viscosity of the liquid at a low viscosity side. The inclination of the slide surface is pref. 30-70 deg. to a horizontal face. By this constitution, the grade of quality of coating is improved by retarding turbulence of a coated surface. |
