Abstract: A ring, preferably in the form of a lock nut, made for combi rolls, which ring includes at least one spring device in which a mechanical compression spring is included that acts between, on one hand, a front press body that is movable to and fro in order to constantly forward a spring force generated by the compression spring and, on the other hand, a support body, which may assume a fixed position, but which is adjustably movable by way of a screw in order to alter the tension in the compression spring.

Abstract: A roll and a roll spring, where spring is in the form of a ring-shaped body manufactured of an elastic material having two axially spaced-apart ends. In a front end of the spring body, at least one first slot opens which extends towards the rear end, without reaching the same, and which separates two forward-facing laminae. In the rear end, at least one second slot opens which extends towards the front end without reaching the same, and which separates two rearward-facing laminae. At each one of the two ends of the spring body, an end surface of a lamina is axially displaced in relation to the end surface of an adjacent lamina. When the spring is clamped between two rings of a roll shaft included in the roll, the protruding end surfaces are subjected to compressive forces that generate a labyrinth-shaped train of spring forces between the end surfaces.

Abstract: A combi roll includes a shaft having two spaced-apart stop rings a plurality of roll rings placed between the stop rings, which roll rings individually are composed of an outer ring of a hard metal, and a concentric inner ring of a more ductile metal, which is permanently bonded to the outer ring metallurgically, and has a flange that projects a distance axially from an end of the outer ring. The individual roll ring is rigidly connected to the shaft by way of one or more locking pins, which are inserted in through holes in the projecting flange of the inner ring and engage holes in the shaft.
