摘要

The cone has an inner cone (1) provided with inner clamping flanges (3), which are distributed on a circumference of the inner cone. The inner cone is fastened to a roller support arm (2) of a roll changer. An outer cone has outer clamping flanges distributed on its circumference, and a hollow cavity of the outer cone extends axially inside of the outer cone. The inner cone is arranged in the hollow cavity of the outer cone. The outer clamping flanges are radially adjustable, where an inner diameter of the hollow cavity is unchangeable.
