Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the breaking accident in a joined part by excessive tension when the tip of a hot-rolled steel strip is wound around the mandrel of a coiler in endless hot rolling. SOLUTION: A joined point is transferred with a tracking device 30, the target cutting point is decided so as to position on the upstream side of the joined point and, even when there is variation in the cutting operation, the joined point is always stably positioned in the revolute position of a preceding material.
