Abstract
A coating apparatus for forming a curtain film of uniform thickness on a suitable substrate, particularly for production of recording/reproducing media such as photosensitive and magnetic media. Jets of an auxiliary liquid are provided in the vicinity of a lip portion of a liquid pouring device which pours the coating film on the substrate. The jets expel an auxiliary liquid which does not affect the characteristics of the coating film, but which does prevent thinning of the curtain film in the vicinity of edge guides of the apparatus. Depending on the height of the curtain film, more than one set of jets may be provided along the length of the curtain film.
