Abstract

The present invention is directed to a support beam for a scraper blade which is in contact with the shell surface of a drying cylinder. The support beam comprises an oblong hollow body made of a fiber composite material wherein the major fiber orientation is essentially in the longitudinal expanse of the hollow body. The hollow body has at least two longitudinal walls of convex curvature as well as two transition sections of convex rounding which connect the longitudinal walls to one another. The radius of curvature of each longitudinal wall is greater than its width while the radius of curvature of each transition zone is smaller than the width of an adjacent longitudinal wall.
