- 3 roll coater (refer FIG. 4) comprised from 3 rolls was illustrated as roll coater 30A, 30B, it is not limited to this, From 1 roll A squeeze coater that is configured, a two-roll coater that includes two rolls, or a configuration that includes three or more rolls may be used, and the applicator rolls 31A and 31B that are in contact with the steel strip have wrinkles. The effect that it is hard to stick is obtained similarly. In addition, when a squeeze coater is used, the effect that the roll which has the function of an applicator roll and a pick-up roll is hard to be caught is acquired. Further, the same effect can be obtained in both the natural rotation and the reverse rotation with respect to the rotation directions of the rolls 31A, 31B, 32A, 32B, 33A, 33B and the like.

- the welded joint part was cut out from the coated steel strip to obtain a coated steel sheet as a product, but the length of the part that needs to be cut off and discarded, that is, the dry film thickness of the coating liquid, was from the target value.
- the length of the part which was detached or the part with poor shape was 9 m (the part before the welding point was 3 m, and the back part was 6 m).
- the unpainted portion is 19 m (the portion before the welding point is 4 m, the rear Since the portion was 15 m), the portion to be cut off and discarded could be reduced by 10 m per coil. As a result, the product yield could be improved by 0.2%.
