Methods of Processing High-Carbon Wire and Metal Cord with Straightening Devices

The deviation from the straightness of the steel cord is affected by the level and distribution of residual stresses. One of the effective ways to reduce residual stresses in the steel cord is the use of alternating metal cord bending. A scheme of alternating metal cord bending on a deforming roller is presented. The influence of the diameter of the deforming roller on the deviation from straightness of the complex design of the metal cord was assessed using the criterion of a comprehensive assessment. The results of the experiment obtained in the manufacture of steel cord using deforming rollers are presented. The diameters of the deforming rollers are determined, which make it possible to reduce the deviation from the straightness of the metal cord of a complex design.
