Sažetak
Steel tire cord, springs and rope wires belong to the group of metal products from which the low residual stresses are required. In this paper the effect of multiple bending of wire on residual stresses of high carbon steel wires has been assessed. It was found that the application of the multi-roller straightening machine in the banding wire process enables to reduce the residual stresses in the drawn wires. It should be also noted that the value of the residual stresses depends on the type of straightener construction. The residual stresses on the basis of stress-strain curve has been determined. It has been stated that the application of seven-rolls straightener gives the best effect of straightening.
