Abstract

1,270,133. Coating webs. FUJI PHOTO FILM CO. Ltd. 30 July, 1969 [1 Aug., 1968], No. 38279/69. Heading D1L. A web 1 is uniformly coated on both sides during passage between two extrusion coating devices 2, 2' from which coating compositions are continuously fed at constant pressure between the web and doctor surfaces 4, 4' thus maintaining the web in a stable position. One or two layers may be supplied by each device from separate slots (e.g. Fig. 1) or two layers may be supplied from a common slot, 6, Fig. 4. During upward passage of the web between the devies a composition D may be fed so as to flow down a surface 10 onto the web or, during downward passage, the devices may be surmounted by open reservoirs, Fig. 5 (not shown). Details are given of coating a film base with various photographic emulsions (Division G2).
