However, there is a disadvantage that a uniform coating film cannot be formed. In order to solve this disadvantage, edge wipers made of blades are provided at both ends of the second roller 2 so as to regulate the width of the coating liquid. However, the edge wiper causes the second roller 2 to be worn out. The coating liquid scraped off by the edge wiper is wasted. Further, when the interval between the dam partition plates 6a and 6b is smaller than the width of the coated paper 7, there is a disadvantage that the uncoated portions at both ends in the width direction of the coated paper 7 are widened.
