In these systems, weaving is carried on an air jet or a water jet to fly weft yarns. However, at the outlet side of the weft yarn, a warp yarn called a catcher for entanglement of the skipped weft yarn is fed out along the warp yarn of the woven fabric. The catcher is constantly spun, and the tip of the flung weft is entangled as described above, and is woven as a woven fabric by heald action while applying tension. In this manner, the tip of the weft entangled in the catcher is cut with a red heater knife, the catcher entangled with the outlet end of the weft is separated from the woven fabric, and the catcher is used as waste for waste. It will be stored in containers and disposed of as industrial waste. On the other hand, the woven fabric is wound up.
