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. |
