ABSTRACT:
The invention relates to a roll bending machine consisting of two rolls capable of adjusting the radius of curvature of the pressured roll, having a rotatable endless belt between the pressured roll and the works, forming the works not only into ring-shaped products of a desired diameter but also into involute-curved, spiral-shaped, elliptical-shaped, triangular-shaped (rounded), rectangular-shaped and other sophisticated curved products, providing a uniform finish to the works, meeting the size tolerance and desired diameter accuracy, eliminating any damage to the works.
