PROBLEM TO BE SOLVED: To establish an manufacturing method for an envelope of airship, etc., using a braider in which the envelope is embodied as a single piece body formed by the braider. SOLUTION: A pair of braiding yarns having a braiding angle±θdeg. to the axis and a center yarn having an angle of zero degree to the axis are processed into a braid layer by the braider BR, and the envelope En for airship, etc., is formed from this braid layer as single piece body, wherein the film thickness of the braid laier at both ends in the axial direction of the envelope is made smaller than the film thickness in the central part about the axial direction. |
