摘要
PROBLEM TO BE SOLVED: To provide a continuously constraining device capable of stably obtaining a uniform welding joint by enhancing the rigidity of a strip when strips are welded in a state lightly butt constrained so that the accuracy of butting of strips 1, 2 at the welding point and in the vicinity thereof can be stably acquired. SOLUTION: Against a strip to be a reference side, a front stage pushing roll 45a and/or a work roll 3a for pushing the strip to the position-fixing roll side at the upstream side of a constraining position by a work roll 3a and a position fixing roll, and a rear stage pushing roll 46 for pushing the strip to the position-fixing roll side at the downstream side of the constraining position by the position-fixing roll are provided, and between the interval between the pair of the backup rolls 5, 6 and divided rolls, a passing space for the laser beam 16 radiated from a welding head 15 of the laser beam machine is formed.
