Abstract

Стальной корд (20), адаптированный для армирования эластомерных продуктов, содержит одну нить сердечника (22), имеющую диаметр нити сердечника D, и 3N нитей слоев (24, 26), закрученных вокруг нити сердечника в одном и том же направлении и с одним и тем же шагом. N находится в диапазоне от четырех до пяти. 3N нитей слоев скомпонованы в виде промежуточного слоя из N нитей (24), имеющих диаметр промежуточного слоя D, и в виде внешнего слоя из 2N нитей (26), имеющих диаметр внешнего слоя D, и стальной корд (20) демонстрирует следующие далее характеристики (D, D, D, в мм): D≤D<D.The steel cord (20), adapted for reinforcing elastomeric products, contains one core thread (22) having a core diameter D and 3N layers of layers (24, 26) twisted around the core thread in the same direction and with one and the same step. N ranges from four to five. 3N strands of layers are arranged as an intermediate layer of N strands (24) having an intermediate layer diameter D, and as an outer layer of 2N strands (26) having an outer layer diameter D, and a steel cord (20) shows the following characteristics ( D, D, D, in mm): D≤D <D.
