Abstract
A combi roll that comprises a roll shaft having a rotationally symmetrical basic shape defined by a central axis, as well as a number of rings in the form of roll rings and spacer rings, each one of which has planar end surfaces that extend between outer and inner, circular limiting edgelines, and that serve as contact surfaces against adjacent rings. At least one of the end surfaces of a ring, preferably a spacer ring, is limited by an inner edgeline, the diameter of which is greater than the outer diameter of the roll shaft. In such a way, the area of the contact surface is reduced while increasing the surface pressure, at the same time as the force transmitting ability of the surface increases by the fact that the radial distance to the center axis is increased.
