  • Apparatus for applying a protective coating to a film strip
    Patent number: 5354379
    Abstract: A method and apparatus are provided for applying a protective coating to a film strip. The apparatus includes a coating unit for applying a coating of a curable liquid material to at least one surface of the film strip, a curing device for curing the coating of liquid material on the film strip into a protective coating, and a transport system for moving the film strip along a path extending from the coating unit to the curing device. The coating unit includes a substantially rigid, porous matrix having therein a plurality of interconnected pores, and is positioned such that the porous matrix contacts the surface of the film strip to be coated. The porous matrix stores the liquid material within the pores thereof and, upon contact with a surface of the film strip, transfers a coating of the liquid material thereto.
