Abstract:
A paint coating apparatus, comprising:a die head having a front lip, a first paint discharge slit, an intermediate lip, a second paint discharge slit, and a rear lip arranged in an upstream order at least in the travel direction of a support body, the die head further having a curved plane, the curved plane formed at a ridge line wherein the ridge line is formed by a tip surface of the intermediate lip and a wall surface of the second paint discharge slit, the curved plane being positioned oblique to the support body; and wherein the curved plane formed at the ridge line satisfies the relationshipLog.theta.=-0.44Log(L.sub.1 /paint coating thickness)+1.5where L.sub.1 represents a curved plane formation length of the curved plane in the travel direction of the support body while L.sub.2 represents an orthogonal length which intersects L.sub.1 and .theta. represents an interior angle defined by L.sub.2 /L.sub.1.
