となるばかりか何らかの解決策が急務であった。Further, since the clamp position of the bent pipe to be cut does not hold the vicinity of the end of the bent pipe, the disc cutter and the end of the bent pipe will be erroneously vibrated during cutting. Therefore, the life of the teeth of the disk cutter due to the irregular vibration becomes extremely short, and the various costs associated with the frequent replacement work of the disk cutter and the cost of parts of the disk cutter increase, and the cutting causes the scattering and scattering. The bending pipe manufacturing apparatus must be completely stopped from the viewpoint of safety even at the time of collecting and collecting bending pipes, so that not only serious reduction in production operation rate and production efficiency but also some solution The measure was urgent.
