PURPOSE:To wind the titled steel plate of high quality by winding the thin steel plate which is annealed after cold rolling and has irregular thickness widthwise in tension states of optimum areas in the beginning of winding and thereafter. CONSTITUTION:A thin steel plate which is annealed after cold rolling and has irregular thickness widthwise is treated with normal 2-10kg/mm.<2> winding tension from the beginning 23 of winding up to a position 24 which corresponds to length about 1/10-1/15 as long as the overall length of the steel plate, thus allowing the steel plate itself to serve as a coil internal surface reinforcing material. In this case, the number of laminated layers is small, so the flatness of the wound steel plate is not spoiled. Then, the winding tension of the steel plate is decreased according to a gradually decreasing type A or stepwise type B up to winding tension 21 which is <=2kg/mm.<2>, and the remaining steel plate is wound entirely, thus winding the thin steel plate completely at a point 25. |
