題がある。(Problems to be Solved by the Invention) However, the conventional method of applying tension to the binder-impregnated braid fiber body a is simply winding the binder-impregnated braid fiber body a around a fixed roll b. The binding agent-impregnated braided fiber body a having a small friction resistance cannot be applied with a desired tension because the binding agent-impregnated braided fiber body a having a small frictional resistance slips with the fixed roll b.
However, for example, when it is not flexible like a glass fiber body, there is a problem that thread breakage occurs when it is wound around the fixed roll c.
