Abstract
A method and a device for coating a hollow cylindrical member. The method includes radially coating an entire inner surface of the hollow cylindrical member with a first coating material discharged by a first slit nozzle and simultaneously circularly coating an entire outer surface of the hollow cylindrical member with a second coating material discharged in an axial direction of the hollow cylindrical member by a second slit nozzle located opposite the first slit nozzle with the hollow cylindrical member therebetween. The first slit nozzle and the second slit nozzle discharge the first coating material and the second coating material, respectively, to a same height of the hollow cylindrical member relative to the inner surface and the outer surface thereof.
