Abstract

In a method of producing stiffening profiles, particularly of reduced weight, for example for robot arms, transmission parts, bicycle frames, loading tailgates, crossing tailgates or the like, the stiffening profile is extruded in its contours and configurations at right angles to its plane and the stiffening profiles are then cut off in a required thickness.
