?BSTRACT A method for producing a fiber roll comprising a load carrying shaft portion and thereon a cover portion made of fiber material. The cover portion is made by subjecting a great number of annular fiber material sheets fitted on the shaft portion to a very strong compression in the axial direction of the roll. The method includs the step of making at least one supply duct leading from an end portion of the roll to the interface of the shaft portion and the cover portion. After the axial compression of the fibe? material, a hardening fluid is fed through the supply duct and pressure is applied thereto so as to force said fluid to penetrate between the cover portion and the shaft portion and to fill all possible cavi- ties between the shaft portion and the cover portion.
