PURPOSE:To prepare a uniform film thickness by supporting both ends of film- like coating liquid with supplementary liquid discharging along the flowing film of the coating liquid in a jet state with an angle in the outside direction when film-like coating liquid is struck against a supporting body to be coated. CONSTITUTION:One or more kinds of film-like coating liquids 11-13 is struck against a supporting body 2 to be coated. Then, both ends of the film-like coating liquid are supported by supplementary liquids 5a, 5b which spout in a jet state along the effluent film of said coating liquid with an angle theta to the outside direction. As a result, even though a curtain film is high or an edge guide is not applied, no local thick coats occur on both side edge parts in the web direction and it is possible to obtain a constant and stable coating film. |
