METHOD FOR PRODUCING A ROLL OF A PAPER/BOARDMAKING MACHINE AND ROLL OF A PAPER/BOARDMAKING MACHINE

摘要

A roll for a paper or board machine is produced by forming a tubular roll blank by bending out of a planar sheet or by means of centrifugal casting. The roll blank is first coated with a material having a modulus of elasticity and a density lower than those of steel and the coated roll blank is turned on a lathe to a desired shape and to a desired surface quality.
