PURPOSE:To prevent the generation of a non-uniform coating layer at both flange parts of a coating layer, in a method for coating a paint liquid by forming the freely falling curtain of said paint liquid on a running support, by coating said paint liquid after both flange parts of the support are bent prior to coating. CONSTITUTION:In a method for coating a paint liquid by impinging the same onto a running support to be coated in such a manner that the freely falling curtain 3 of the paint liquid is formed, both flange parts of the support parellel with the running direction A of said support 1 are bent to a non-coating surface side by a support bending instrument 5 and a bar 5'. In the next stage, the freely falling curtain 3 of the paint liquid of which flange parts are supported by edge guides 2 and the width is wider than that of the bent support is formed and a coating layer 4 is formed on the support 1. Among the paint liquid forming the curtain 3, the liquid not coated on said support in the outer side from the corner part 10 of the support 1 is flowed down while the width thereof is made narrow and, therefore, the bent support part 11 is not coated. As referred above, a non-uniform part in the vicinity of the edge guide 2 is not coated and, therefore, a non-uniform coating layer is not generated.
