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.
