PURPOSE: To mechanically and efficiently form a handwoven brocade pattern woven fabric by making guide members for ground warp yarns and pattern weft yarns perform reciprocating motion in a specific direction, alternately forming a closed gap and an opened gap and picking a linear weft yarn in the weaving width direction in the closed gap.

CONSTITUTION: An opened gap is formed from ground warp yarns (a) and (b) respectively guided with guide members 10 and 16 for warp yarns and the guide member 10 for the warp yarns and a guide member group 20 for pattern weft yarns and the guide member 16 for the warp yarns and a guide member group 22 for the pattern weft yarns are oppositely moved to form a closed gap crossed in an X-shaped state. A rapier band 15 is passed through the closed gap X to pass the linear weft yarns through the weaving width direction and carry out the picking. The above guide members 10 and 16 and the guide member groups 20 and 22 are moved in the direction of arrows to form an opened gap again. The weaving process is repeated to thereby mechanically and efficiently weave a handwoven brocade.
