Abstract
A device for fixing a material used for balancing of a roll in which a support and fixing construction for a fluidized balancing material is placed into the roll interior in contact with an inner face of the roll. The fluidized balancing material is then placed inside the roll at the location required by the balancing, where it is fixed and hardens. The support and fixing construction includes openings, which permit the balancing material to be placed at both sides of the support and fixing construction before it hardens and is fixed at the location required by the balancing.
