ABSTRACT:
An extrusion coating device comprising a die having its distal end composed of an upper lip and a lower lip and having a slit provided between the upper lip and the lower lip, for extruding a paint through the slit to apply the paint onto a flexible support continuously running along distal end surfaces of the upper lip and the lower lip is disclosed. The distal end of the lower lip of the die is constituted continuously from the slit by a planar portion, a first curve portion and a second curved portion. An inclination angle of the planar portion, a radius of curvature of the first curved portion, and a radius of curvature and a center of curvature of the second curved portion are set within predetermined ranges, respectively. Thus, with this coating device, a coated film of satisfactory shape having no coating irregularity or stripe can be formed even when high-speed coating and reduction in coating thickness are carried out or when dusts and particles are attached on the support surface.
