摘要

FIELD: rolled stock production. ^ SUBSTANCE: roll includes arbor with threaded portion and with bandage and nut placed in said portion; locking members. According to invention bandage is joined with arbor along cone surface with taper angle in range (1 : 20) - (1 : 30). Locking members are in the form of lock screws placed in nut body along its circumference and equally spaced one from other. Said screws are directly screwed into adjoined end of bandage. On surface of bandage adjoined end in zones of contact with screws there are tapered planes inclined relative to axis by angle less than lead angle of turns of nut thread. Length of said planes is in range (1.5 - 2.0)d where d - diameter of lock screws. Said taped planes with opposite inclination angles are arranged alternatively. ^ EFFECT: elimination turning over of roll bandage around its axis at occurring of instant overloads, possibility for mounting/dismounting bandages with use of simple attachments.
