Abstract: PROBLEM TO BE SOLVED: To provide a coating method and apparatus to obtain a quality product free from defects by preventing inclusion of air from the ends of coating region of coating liquid especially near the coating means to protect the generation of such coating defects. SOLUTION: This coating method applies a coating liquid to a traveling web to obtain a desired coating thickness. A web travels in the direction of a coating means while being pressed in the direction of a coating means at least neat the edge part in the web width direction of the coating regions of the coating liquid. The coating apparatus is also disclosed. COPYRIGHT: (C)2003,JPO
