Claims

[Scope of Claim for Utility Model Registration] (1) A saucer into which a coating liquid is placed, a coating roller that is partially immersed in the coating liquid and rotates while adhering the coating liquid to the outer peripheral surface, and a substrate that is intermittently placed on the coating roller. In the roll coater, a fine recess is formed on the outer circumferential surface of the application roller so that the amount of adhesion differs between the central part and the outer part to change the surface condition of the application roller. A roll coater characterized by changes. (2) The roll coater according to claim 1, wherein the surface condition of the application roller is changed so that the amount of adhesion decreases continuously from the central part to the outer part. (3) The roll coater according to claim 1, wherein the surface condition of the coating roller is changed so that the amount of adhesion gradually decreases from the center portion to the outer portion. (4) The roll coater according to claim 1, claim 2, or claim 3, wherein the recess is a vertical groove parallel to the rotation direction of the coating roller. (5) The recessed portion is a horizontal groove parallel to the rotation axis of the applicator roller.
The roll coater described in item 2) or item (3). (6) The roll coater according to claim 1, claim 2, or claim 3, wherein the recess is a knurled groove. (7) The roll coater according to claim 1, claim 2, or claim 3, wherein the recess is an irregular groove. (8) The roll coater according to claim (1), (2), or (3), wherein the recess is a point-like recess.
