  • Patent number: 6775970
    Abstract: A process and apparatus are disclosed for making a hybrid cord which may be used. The process combines and twists at least three yarns together where one of the yarns is different. The different yarn maybe of a different size (denier), or made from a different polymer, or both. The hybrid cord may be used in tires, hoses, v-belts, and conveyor belts, for example. The apparatus is a modified direct cabler machine in which at least two yarns from a creel are combined and twisted about a third yarn issuing from a spindle pot. It is contemplated that the different yarn is preferably one of the yarns on the creel. Various tensioners are employed to tightly wrap or twist the yarns together (generally at a rate of from about 5-12 turns per linear inch of the yarn issuing from the spindle pot), and to wind the cord on a bobbin.
