<p>PURPOSE:To substantially improve the yield of the product by efficiently adding a starting end part and a completing end part to a metal strip in its rolling. CONSTITUTION:A bottom part 37 which is a completing end of a preceding metal strip is joined with a top part 36 which is a starting end of a succeeding metal strip at a welding part 35. In a tandem cold rolling mill consisting of #1 stand 21, #2 stand 22 and #3 stand 23, the top part 36 and the bottom part 37 are rolled to the predetermined thickness to be separated from the residual part with the gage change and without stopping the line. The top part 36 and the bottom part 37 of the predetermined thickness are efficiently formed on the metal strip after the part close to the welding part 35 is cut by a flying shears 32.</p> |
