Method of manufacturing a metallic belt of high strength, and apparatus for use in said method

摘要

A method of manufacturing an endless metallic belt of high strength for use as a drive belt or a part of a drive belt. A stress gradient is introduced in the belt in the radial direction thereof by bending the belt at such a radius as to produce plastic deformation of the metal. The belt is first subjected to tensile stress, which stress is maintained during the bending process.
