Roll and a spring therefor

A spring for a roll, comprising:

• a ring-shaped body which is manufactured of an elastic material and has two axially spaced-apart ends, wherein, in a front end of the body, at least one first slot opens which extends towards the rear end without reaching the same, and which separates two forward-facing laminae, having ring-shaped end surfaces, that 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, having ring-shaped end surfaces, and that at each one of two ends of the body, an end surface of a lamina protrudes axially in relation to the end surface of an adjacent lamina, wherein the end surface of the individual lamina is planar and extends perpendicularly to the axial extension of the spring wherein the axial length of the slot amounts to at least 60% of the length of the spring body.
