To weave a woven fabric in which a weft wavy pattern partially exists in an ordinary weave pattern by providing warps with a tension change by the rotations of the outer peripheral surface of a back roll, a spiral groove part formed on the outer peripheral surface and the back roll, forming a weft wavy pattern by the tension change of the warps, raising a large number of the warps by the separation member of a contacting and separating mechanism, separating the warps from the outer peripheral surface of the back roll, providing the warps with a prescribed tension, and weaving a woven fabric of an ordinary weave pattern having a uniform weft density.
The warp T is provided with a tension change by the rotations of the outer peripheral surface 5a of the back roll 5, the spiral groove part 5b formed on the outer peripheral surface and the back roll, difference in density of the weft Y is caused by the tension change of the warp to form the weft wavy pattern D and the contacting and separating mechanism 14 having a contacting and separating member 15 for contacting and separating a large number of the warps from the outer peripheral surface of the back roll is arranged.
