SUBSTANCE: built-up rolling roll includes arbor with threaded portion and shoulder; bandage mounted on arbor and members for fixing bandage having nut screwed onto threaded portion of arbor. On end of bandage turned to shoulder there are recesses forming two diametrically opposite radial cylindrical ducts in which sleeves with internal thread are arranged. Screws passed through said sleeves are turned-in to arbor. Nut has radial threaded opening into which fixing screw is turned-in. End of fixing screw passes to cylindrical duct provided in arbor. Invention prevents turning over and shifting of bandage relative to arbor.
