するロールコータ。[Claims for Utility Model Registration] 1. A back-up roller that is rotatably supported and has a strip to be coated wrapped around its outer circumferential surface; A large number of groove-like or hole-like recesses for holding the coating liquid are formed on the surface, and the outer circumferential surface thereof is applied to the surface of the strip to be coated, which is wound and supported by the back-up roller, on the opposite side of the back-up roller. a coating roller that is brought into contact with the outer peripheral surface of the coating roller; a pick-up roller that is disposed parallel to the coating roller and rotatably supported and whose outer peripheral surface contacts the outer peripheral surface of the coating roller; and a pick-up roller that applies a coating liquid to the outer peripheral surface of the pick-up roller. In the roll coater, the width of the outer circumferential surface of the coating roller is made larger than the width of the outer circumferential surface of the pick-up roller, so that both ends of the outer circumferential surface of the coating roller are connected to both ends of the outer circumferential surface of the pick-up roller. Both rollers are arranged so that they are located on the outer side of each roller, and a recess is not formed on both edges of the outer peripheral surface of the coating roller, or the outer periphery is smaller than the recess formed in the center of the outer peripheral surface of the coating roller. A roll coater characterized in that a concave portion having a small volume per unit area on a surface is formed. 2. A back-up roller that is rotatably supported and has a strip to be coated wrapped around its outer peripheral surface; A coating roller that is brought into contact with the surface of the rotated and supported strip to be coated from the opposite side of the back-up roller; a pick-up roller that is brought into contact with the
In a roll coater comprising a coating liquid supply means for supplying a coating liquid to the outer circumferential surface of the pick-up roller, the outer circumferential surface of the coating roller is a smooth surface, and the outer circumferential surface of the pick-up roller is provided with groove-like or hole-like recesses. Along with forming a large number,
The width of the outer circumferential surface of the coating roller is made larger than the width of the outer circumferential surface of the pick-up roller, and both rollers are arranged so that both ends of the outer circumferential surface of the coating roller are located outside of both ends of the outer circumferential surface of the pick-up roller. A roll coater that is characterized by:
