ABSTRACT:
A method and apparatus for coating thixotropic high viscosity liquid coating compositions on a moving web at a narrow coating in such a manner as to provide a flat coating surface. The apparatus is provided with at least two liquid discharge ports arranged side by side opposite to the moving web so that the liquids are discharged through the ports and the edge of the coating liquid streams meet on the web. The apparatus is further provided with an extrusion type hopper having two slide members of which the tip ends are in the form of a knife edge, the slide members being arranged so that the knife edges are directed inwardly toward each other, at least one partition plate interposed between the slide members so as to equally divide the distance between the internal surfaces of the slide members. The method of this invention is well suited for use in applying a magnetic recording stripe to a motion picture film.
