PURPOSE:To join rolling stocks together rapidly and surely by blanking reparately the rear end of a preceding rolling stock and the front end of a succeeding one, in zigzags, in a hot rolling line, and fitting the blanked parts to each other to weld the side faces of blanked ends. CONSTITUTION:When the rear end of a preceding rolling stock 6a and the front end of a succeeding rolling stock 6b pass through detectors 56a, 56b, on a hot rolling line 9, guiding passages 90a, 90b are moved downward and upward respectively to enter the stocks 6a, 6b in cutting units 50a, 50b respectively. The ends of stocks 6a, 6b are blanked into zigzag shapes by respective cutting units 50 consisting each of upper and lower cutters 51, 52, and then the blanked parts are fitted to each other by the movements of passages 90a, 90b. Further, the side faces of fitting parts are welded together to finish the joining. In this way, the hot rolling stocks are joined together rapidly and surely in on-line. |
