    摘要： In an extrusion type coating head according to the present invention, a center line average roughness (Ra) of an inner wall surface of a pocket is made in a predetermined range of 3.5 .mu.m or less and preferably a curvature part is provided, in the part where a surface of a slit joins to a surface of the pocket, which has the radius of curvature R of within a predetermined range. By these configurations, an easiness of cleaning in the pocket of the extrusion type coating head which is difficult to be cleaned is remarkably improved in particular, the rate of operation is improved, labor is saved, and adverse effects are prevented that might be brought by insufficient cleaning on the product coating such as streak generated on the coating surface and thickness fluctuation in the coating.

    摘要： In a coating apparatus having an extrusion coating head, the working value H of a back end edge which corresponds to an end portion at the downstream side of a support feeding direction of a back edge of the extrusion coating head is set to 25 .mu.m or less, and the straightness of said back end edge with respect to the coating width is set to 5 .mu.m or less. Accordingly, a coating operation to form coated films at a stable thickness can be stably performed without occurrence of streaks and coating unevenness on the films, and a judgment on coating surface characteristics can be readily performed without actually carrying the coating operation.
