ABSTRACT OF THE DISCLOSURE 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.

L'invention porte sur un bras support pour un couteau racloir qui touche à la surface extérieure d'un cylindre sécheur. Le bras support est constitué d'un corps creux oblong composé d'une matière composite fibreuse dont l'orientation principale des fibres va essentiellement dans le sens longitudinal du corps creux. Le corps en question comporte au moins deux parois longitudinales de courbure convexe et deux sections de transition d'arrondissure convexe qui relient les parois l'une à l'autre. Le rayon de courbure de chaque paroi longitudinale est plus grand que la largeur des parois, tandis que le rayon de courbure de chaque section de transition est plus petit que la largeur d'une paroi longitudinale avoisinante.
