[AJL] Weft breakage outside the woven fabric ③

③ Reduce rpm

It is necessary to slow down the weft to alleviate the shock when the weft arrives.
The most effective way to slow down the weft speed is to reduce rpm.
Since the amount of air required decreases when rpm is reduced, it is also effective for ① and ②.
The disadvantage is that the production volume per hour decreases,
but if the weft breakage is cured only by this method, the actual production volume increases.
Therefore, the slowdown solution should be addressed last.
