The invention comprises a multi-ribbed belt having a tensile cord(10). The tensile cord having areas (5, 6) of opposite twist along a length of a single cord. In particular, a tensile cord comprises S twist (5) sections and Z twist (6) sections. An S twist section is separated from a Z twist section by a node (3), thereby creating alternate S twist and Z twist sections along a length of a tensile cord. Therefore, the inventive belt comprises a belt having a tensile cord having a random distribution of S twist sections and Z twist sections along a length of the belt as well as across a width of the belt. This significantly reduces tracking force while using only a single cord in belt construction.
L'invention concerne une courroie à stries multiples comportant une corde (10) de traction. Cette corde de traction comprend des zones (5, 6) torsadées en sens opposé le long d'une même corde. La corde de traction comprend en particulier des sections (5) à torsion S et des sections (6) à torsion Z. Chaque section à torsion S est séparée de la section à torsion Z par un noeud (3), de sorte que des sections multiples à torsion S et à torsion Z sont formées le long de la corde de traction. La courroie décrite comporte par conséquent une corde de traction comprenant des sections à torsion S et des sections à torsion Z réparties de manière aléatoire sur la longueur de la courroie ainsi que sur la largeur de la courroie. Cette configuration permet de réduire sensiblement la force d'appui dans une structure de courroie à corde unique.
