The invention is concerned with a method of forming corrugations in one limb of an L-shaped strip of uncured rubber to form an edge for an endless conveyor. The strip is wound around a shaper device so that the strip takes up a curved shape with the outer edge of said one limb placed under tension, and then the shaper device is operated to perform portions of said one limb into corrugations. The portions are held in the deformed positions while the strip is cured. |
