Abstract
In a coating method and apparatus for applying coating liquid onto a web, the coating apparatus includes a rotating member rotatable and contacting with the web; and a support member supporting rotatably the rotating member and including a liquid reservoir formed between the rotating member and the support member, a fluid supply pipe, a cavity filled with the coating liquid and connecting to the fluid supply pipe, and a slit communicating the cavity with the liquid reservoir. The rotating member is supported by a fluid pressure of the liquid reservoir and the coating liquid supplied from the liquid reservoir forms a bead of the coating liquid by the rotating member between the web and the rotating member. The rotating member is floated uniformly in the widthwise direction by the fluid pressure so as to keep a predetermined clearance away from the support member to provide a stable coating. The bead is made uniform in the widthwise direction under any conditions.
