PURPOSE:To remove shape deformation effectively by winding a sheet metal supplied from the inlet side using an inlet side bridal roller, inlet side deflector roller, drum, outlet side deflector roller, and outlet side fridal roller sequentially. CONSTITUTION:The inlet side bridal roller 2 giving a tension to the sheet metal 1, inlet side deflector roller 6 giving a drawing under a constant tension to the sheet metal 1, drum 4 having a diameter of at least 500 times larger than the sheet metal thickness, outlet side deflector roller 10 giving a drawing under a constant tension to the band 1, and outlet side bridal roller 3 giving a tension to the band 1 are installed in due order. The band 1 supplied from the inlet side is wound by the inlet side fridal roller 2, inlet side deflector roller 6, drum 4, outlet side deflector roller 10, and outlet side bridal roller 3 sequentially and the shape deformation of the band 1 is removed.
