ABSTRACT:
An apparatus for applying coating material in the form of stripes onto a film traveling in a predetermined direction is provided with a coating material nozzle which effuses coating material while supporting the film. The contact support surface of the nozzle in contact with the film is a flat surface, along which the film travels. The coating material nozzle has thereon applicator grooves for uniformly forming the cross-sectional shape of coating material applied in the form of stripes onto the film. Effusion ports or discharge ports for coating material are provided in the bottom surface of the applicator grooves. Coating material is fed to the coating material nozzle through a gear pump, which is adapted to control the coating material supply so that the coating material within the applicator grooves has a pressure lower than atmospheric pressure. In addition, there may be provided a plate member for blowing air uniformly and opposed to the contact support surface of the coating material nozzle contacted by the film. The air from this plate is blown against the traveling film on its rear side.
