• the weaving method comprising:
• providing a preparatory water supply period for the weft insertion nozzle having a pausing period that weft insertion has been paused continuously for at least ten picks,
• the preparatory water supply period including at least a point one pick before a weft insertion period which a weft insertion is executed by the weft insertion nozzle and including the number of pick which is less than the pausing period,
• the preparatory water supply period being provided within the pausing period, and
• having the water supply unit execute an operation to supply the weft insertion nozzle only for the preparatory water supply period in a state where the weft is locked by the locking pin and gripped by the gripper.
