Intermesh effect on roller straighteningprocess of single layer steel cordn

摘要

This paper deals with the effect of the intermesh on the roller straightening process of a singlenlayer steel cord. A single layer steel cord, which is constructed with three drawn wires, is selectednas a target structure for stranding experiments. Intermeshes at the inlet and outlet of the rollernstraightening device are selected as design parameters. A design table is constructed fornexperiments with the variation of two intermeshes of the roller straightening device. Experimentsnwere carried out to measure the three assessment items for a single layer steel cord such as thenresidual torsion of a steel cord, the arc height of a steel cord and the preform of a single wire inneach design case for the quantitative evaluation of a steel cord quality. The sensitivity analysis isnperformed for design parameters based on the data measured. Prediction equations of the threenassessment items are constructed from the regression analysis. The prediction equationsnconstructed can be utilised as a design guideline for the roller straightening process of a singlenlayer steel cord.nblanking process are increased.
