Claims

[Claims for Utility Model Registration] The cylindrical outer peripheral surface has substantially circumferential grooves with uniform pitch, and is pressed against the rotating coaching roll and the coaching roll outer peripheral surface in parallel to the coaching roll rotation axis direction. A roll coater consists of a doctor bar that carries the substrate, and a back-up roll that conveys the substrate while keeping it in contact with the coaching roll. The width in the vertical direction of the front end surface of the doctor bar that comes into pressure contact with the doctor bar is made larger than or at least equal to the width in the vertical direction of the flat pressure contact surface that is pressed by the doctor bar and formed on the outer peripheral surface of the coaching roll. roll coater.
