摘要：PROBLEM TO BE SOLVED: To wipe-clean nozzle holes of the head of a liquid coater without color mixing, etc. SOLUTION: Two or more rows of a large number of nozzle holes discharging a liquid are arranged in the head in such a way that their openings are aligned in a plane, and the openings of nozzle holes are wipe-cleaned by bringing the openings of nozzle holes into contact with a wiping material 6 while moving the head and the wiping material 6 relatively in one direction Y. When the head and the wiping material 6 are moved relatively in the direction Y, the head is rotated preliminarily by a desired angle around an axis perpendicular to the plane so that the trajectories of the openings of nozzle holes do not superimposed mutually among rows of nozzle holes of 8R1, 8G1, 8B1, 8R2, 8G2 and 8B2. Because there occurs no adhesion of different liquids to the openings of nozzle holes through the wiping material, mixing of the different liquids is prevented, enabling appropriate coating of liquids.
