ABSTRACT:
Hot working roller reinforced with a working jacket of hard metal or the like, the jacket being prestressed in the direction of the roller axis by a clamping force acting via clamping rings presenting clamping surfaces inclined with respect to the roller axis, with the jacket being separated from the roller body by an annular gap having a height such that during use of the roller the outer surface of the roller body remains out of contact with the inner surface of the jacket over the entire intended operating temperature range of the roller, and the clamping surfaces being inclined in a direction such that the clamping force acting on the jacket presents a radially outwardly directed component.
