The invention comprises a multi-ribbed belt having a tensile cord. The tensile cord having areas of opposite twist along a length of a single cord. In particular, a tensile cord comprises S twist sections and Z twist sections. An S twist section is separated from a Z twist section by a node, 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. |
