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