In an apparatus for applying a film of coating solution to each side of a web such as paper, resin film, etc., there is provided an air-flotation type mini turn bar ( 4 ) to the downstream side of the nipping portions ( 20 ) of two applicator rolls ( 2,2 ). The air-flotation type mini turn bar ( 4 ) is used to convey the web ( 1 ) while holding the web on the surface of one of the two applicator rolls ( 2 ), after it passes between the nipping portions ( 20 ). In this way, the occurrence of flaws in the coated surfaces of the web ( 1 ) is prevented, the occurrence of a mist and coating unevenness is suppressed, and a film of coating solution is formed evenly on each side of the web.
