  • Patent number: 7918180
    Abstract: A film forming apparatus to form a coating film by applying a coating material to an outer circumferential surface of a cylindrical object to be coated, includes a material applying device having a nozzle unit to apply the coating material to the outer circumferential surface of the object and a material supplying unit to supply the coating material to the nozzle unit and a moving device configured to move the nozzle unit relatively to the object such that the coating material is applied uniformly to the outer circumferential surface of the object. The moving device includes an object holding unit configured to hold the object, a nozzle moving unit configured to move relatively the nozzle unit with respect to the object holding unit along a longitudinal axis of the object holding unit, and a guide unit configured to guide the nozzle unit along the object holding unit as the nozzle unit moves along the object holding unit such that an interval between the nozzle unit and the object is maintained constant.

  • Publication number: 20070215045
    Abstract: The present invention is directed to a coating film forming apparatus 1. The apparatus 1 includes a coating unit 11, a coating material supply unit 10, and a control unit 12. The coating unit 11 contains a holding unit 18 for holding a substrate 4, a coating nozzle 19, and a movable unit 20. The coating nozzle 19 is provided with a slit for discharge coating material to an inner circumferential surface, formed in annular shape. The movable unit 20 moves the coating nozzle 19 along a shaft center P of the substrate 4. The control unit 12 controls to apply coating material 7 to an outer circumferential surface 4c of the substrate 4 from a lower end 4a upward in order.
