The invention relates in one aspect, to a roll, and, in another aspect, to a roll spring which is the core of the invention. The spring is in the form of a ring-shaped body (7) manufactured of an elastic material having two axially spaced-apart ends (13, 14). In a front end (13) of the spring body at least one first slot (15) opens which extends towards the rear end (14), without reaching the same, and which separates two forward-facing laminae (16, 17). In the rear end (14) at least one second slot (25) opens which extends towards the front end (13) without reaching the same, and which separates two rearward-facing laminae (27, 28). At each one of the two ends of the spring body, an end surface (19, 31) of a lamina is axially displaced in relation to the end surface (20, 30) 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. |
