摘要

PROBLEM TO BE SOLVED: To provide a roll blade coating method and a roll blade coating apparatus which can suppress variations in adhesion amount of a coating liquid constantly occurring in the width direction in roll blade coating, prevent the adhesion amount of the coating liquid in the vicinity of both ends of the web from becoming smaller, and obtain uniform adhesion amount of the coating liquid in the width direction.;SOLUTION: The roll blade coating method includes transferring an excessive amount of the coating liquid onto the continuously running web, and then adjusting the coating liquid to a desired adhesion amount with a roll blade, wherein a plurality of air cylinders each configured to press a holding member are arranged in a side of the holding member, which side is opposite to a side where the holding member holds the roll blade, so that the air cylinders can separately be adjusted in air pressure.;COPYRIGHT: (C)2012,JPO&INPIT
