PROBLEM TO BE SOLVED: To provide a device and a method for winding a high-strength thick hot-rolled steel sheet around a coil in such a state that the springback deformation of the high-strength thick hot-rolled steel plate is reduced. SOLUTION: A winding device having pinch rolls, wrapper rolls and a mandrel is provided with a bending/unbending means composed of three rolls, wherein the high-strength thick hot-rolled steel plate which is passed through the pinch rolls and guided to the mandrel is subjected to bending and unbending work in winding the steel sheet, thereby the springback of the coil is suppressed.
