Envelope manufacturing method by the braider

摘要

It is an object of the present invention to provide the envelope manufacturing method by the braider such that the envelope like the airship is formed as one object composed by the braider. The envelope manufacturing method by the braider, wherein a pair of the braiding material whose braiding angle is ±theta° to the axis and the axial material whose angle is 0° to the axis are organized as the braiding layer by the braider BR and the envelope En like the airship is composed as one body by said braiding layer and the thickness of the braiding layer in the axial both end parts of said airship envelope is arranged to be formed thinner than the thickness in the axial central part.
