Theoretical bases of the decision of a deviation from the steel cord straightness at industrial manufacture on double twisting cable machines are considered. Specified relevance of the proposed research topic. The influence of tension and bend application to the steel cord before stress relaxation during the discharge on the coils for several days on steel cord straightness was studied. (Macro level). In the process of a steel cord bending on a deforming roller, the bending stresses were formed, as well as the displacements in the construction of the steel cord, expressed in the displacement of the contact points. A numerical model of the steel cord bending with a simple single-layer structure with different steel cord tension as a variable parameter is constructed. The diameter of the deforming roller was selected with recommendations of previous studies. To assess the impact of the proposed values the integrated evaluation criterion in conjunction with the optimization method was used. With the proposed methods, the effect of steel cord tension on its straightness was established. Experiments of the effect of steel cord tension have been conducted in industrial conditions. Positive results have been obtained with the correspondence of the practical results of numerical simulation. In practice, the results in the numerical modeling of the behavior of the steel cord 2х0.30НТ under the influence of complex stress-strain materials on a thin wire during the assembly of the steel cord and subsequent processing of the finished steel cord in the straightening devices and when winding onto the take-up reel are confirmed.
