PURPOSE:To prevent the generation of the bending between the end parts of a preceding steel strip and a succeeding steel strip by superposing the rear end of the former and the forward end of the latter, and feeding the preceding steel strip and the succeeding steel strip to the fixed position in a welding machine in this state. CONSTITUTION:The feed of a preceding steel strip 2a is stopped at the point of the time when the rear end of a preceding steel strip 2a passes pinch rolls 3 for letting off the steel strip. At the same time, the rear end part of the strip 2a is inclined downward from the pass line, and the forward end of the strip 8a passing the rolls 3 is placed by gravity sagging on the rear end part of the strip 2a. The rear end part of the strip 2a is reset on the pass line. The strip 2a and the strip 8a in the overlapped state are fed and controlled up to the fixed position in a welding machine 5. |
