In this case, since the thread end fixing mechanism E includes a pair of adhesive tapes NN arranged opposite to each other,
The yarn end side of the warp R can be arranged and fixed in a single-layer sheet between the adhesive tapes N and N, and the structure can be simplified. In this case, the warp R is stretched by the multilayer yarn tensioning mechanism A.
