Coating method

摘要

By optimizing the pressure condition for sucking up an excess of coating liquid with a recovering slit (32), a coating layer on a web (12) with a very small and even thickness can be obtained. In a coating method using two slits of a coating slit (30) and the recovering slit (32), a liquid pressure P (MPa) at a suction port (32A) of the recovering slit (32) is adjusted in a range of 0.05 > P ‰¥ 0. Thus, coating thickness variations in the web (12) width direction of the coating layer formed on the web (12) can be restrained, and score-like coating omission can be prevented from occurring on the coating layer surface.
