Claims

[Scope of Claim for Utility Model Registration] A back-up roll disposed between the supply path and the discharge path of the substrate, and surplus liquid flow grooves disposed above the back-up roll at both ends. It is equipped with a coating roll, a doctor means that can move toward and away from the coating roll, and a rotational drive means that rotationally drives the coating roll and the back-up roll. In a roll coater that is formed shorter than the dimension between the surplus liquid flow grooves at both ends, and is provided with a surplus liquid flow transmission means corresponding to each surplus liquid flow groove, the surplus liquid flow transmission means is a flow conduction means. A roll comprising a surplus liquid receiving part at the upper part of the pipe, the receiving part being arranged close to the lower side of the surplus liquid flow groove, and the rotating driving means being covered with a dust removal chamber.
