Abstract

In a coating method, a precoating layer is applied to one surface of a web W laid between a plurality of web guide rollers GR while a leading end surface of an extrusion-type head portion EX is pressed against the one surface of the web. Accordingly, entrained air increasing as the transferring speed of the web becomes higher could be prevented from entering a coating point on a doctor edge surface near an outlet of a slot by the meniscus of coating liquid formed in a slight gap between the front edge surface of the extrusion-type head portion and the one surface of the web approaching there. As a result, the precoating layer having an excessive amount can be applied stably without turbulence at the coating point caused by the entrained air. Further, coating can be done stably in the rod portion by setting the thickness of the precoating layer for a final coating layer and a virtual coating layer.
