PURPOSE: To provide a method for weaving by which warp yarn breakage due to sagging or slacking of pattern warp yarns or defective flying of weft yarns due to defective shedding can be prevented from occurring by using a machine of a specification of using usual one warp yarn beam as a base.

CONSTITUTION: The characteristic of this method for weaving pattern woven fabric comprises operating an easing motion for pattern warp yarns in the direction opposite to that of an easing motion for ground warp yarns in weaving pattern woven fabric having a weaving pattern in the warp yarn direction. Furthermore, the characteristic of this apparatus for easing for weaving the pattern woven fabric comprises an easing roller 3 for the ground warp yarns, a subeasing roller 4 for the pattern warp yarns and further a means for driving the easing roller and the subeasing roller so as to operate the easing motion for the ground warp yarns 1 and the easing motion for the pattern warp yarns 2 in the opposite direction in an apparatus for easing in a loom for weaving the pattern woven fabric.
