METHOD FOR SIMULTANEOUSLY COATING INNER AND OUTER SURFACES OF CYLINDRICAL MEMBER, AND APPQARATUS FOR SIMULTANEOUSLY COATING INNER AND OUTER SURFACES OF CYLINDRICAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously coating the inner and outer surfaces of a cylindrical member highly precisely and efficiently without significantly raising equipment cost even in the case of a flexible material.;SOLUTION: In the method for simultaneously coating the inner and outer surfaces of the cylindrical member while keeping the axis of the cylindrical member vertical, the inner and outer surfaces are simultaneously coated by a first slit-like nozzle radially spraying first coating to the whole inner periphery of the cylindrical member provided to be the inner surface of the cylindrical member, and a second slit-like nozzle annularly spraying second coating in the axial direction of the cylindrical member to the whole outer periphery of the cylindrical member, facing the first nozzle and to be the outer surface of the cylindrical member, at a position wherein the height of the first coating sprayed from the first nozzle in contact with the inner surface of the cylindrical member is the same as the height of the second coating sprayed from the second nozzle in contact with the outer surface of the cylindrical member.;COPYRIGHT: (C)2009,JPO&INPIT
