PURPOSE:To produce a thin sheet having high thickness accuracy and guality by moving the position of a coiling center according to the quantity of coiling thereby maintaining the specified pass line position and measuring the thickness of the thin sheet metal with high accuracy. CONSTITUTION:The center of a coiling drum 6a moves on the revolving locus 10 of the drum 6a and advances to 01-0n from the start till end of coiling. The movement of the drum 6a is controlled according to the quantity of coiling of the thin sheet 5 coiled on the outside periphery of the drum 6a, i.e., the quantity of fatting-up by coiling so as to contact always tangently with the pass line 11 set in the stage of starting the coiling, by which the sheet is coiled up to the max. coil diameter 8 without fluctuation in the position of the pass line 11. |
