Coating apparatus and machining method therefor.

摘要

In a coating apparatus where a coating composition is supplied from the lateral side of a manifold, a linear or curved taper along the width of the coating apparatus is given to the length a slit in the direction of flowing-out of the coating composition, so that the slit length is shorter in the counter-supply side than in the supply side of the manifold. The coating apparatus can make the distribution of the quantity of coating uniform in the case where the width of coating is large, or in the case where the quantity of flow per unit width in an individual layer is large. <IMAGE>
