PURPOSE:To obtain a tubular structure deflected in any direction by a method wherein a weft is twined round a core body having a bent form or a flexible core body, which is bent, and a group of warps and at the same time the feeding speeds of the warps are relatively changed among themselves. CONSTITUTION:Warps 1, 1', 1'', 1''' and another series of groups are shifted through a ring 4 along a core body 6 upward while repeating up and down movements relative to adjoining warps in order for the weft 2 to intersect and twine round groups of the warps. In this case, the shape of the core body 6, round which the weft 2 is twined, is not simple straight column but bent in an direction in the course to its tip. By shifting a woven body in the direction directing to the tip of the inflect core body 6 after the weft 2 intersect and twine round groups of the warps, the shifting amount of the warps locating at the outer side of the inflect part is rendered to be larger than that of the warps locating at the inner side of the inflect portion, resulting in enabling to manufacture an inflect structure B. |
