PURPOSE:To wind a steel strip by simply correcting a winding thickness by detecting a difference in winding thicknesses of near both side end parts of a ringlike steel strip winding body and changing an apparent thickness by plastically deforming a part near a side end of the strip being just before winding. CONSTITUTION:A steel strip 1 is wound on a mandrel 2 in the direction of the arrow to form a ringlike steel strip assembly body 3. For the above steel strip winding method, a rotating roll 6 being brought into contact with the body 3 by a spring 12 is installed and up and down motions of the roll 6 is detected by a detection dog 13 and magnetic sensors 14, 15 to detect a difference between both winding thicknesses of parts near both the side ends. Cylinders 20a, 20b are actuated based on the detection signal and a part near a side end of the strip 1 being just before winding is plastically deformed into projected shapes by use of an asterisk roller 16 and a V-groove roller 19. Thus, an apparent thickness of the strip 1 is changed to wind the strip 1 with the winding thickness of the wound body 3 corrected.
