摘要： An open end roving, spinning, and spinning and twisting machine in which a twist belt or twist drum or twist drums cooperates with an elongate twist needle along the length of which drafted lengths of fibrous material are delivered sequentially so that the fibrous material will be loaded and wound upon the twist needle and then passed to delivery rolls for removing the fibrous material as a continuous length from the twist needle while imparting twist thereto. The twist needle is sandwiched between the rotating twist drums or the twist belt and a rotating twist drum having individual sectors which longitudinally reciprocate and help in feeding the fibrous material from the twist needle. The twist needle may be hollow so as to receive and pass a roving, yarn or the like which is integrated into the final product. A single twist needle or plurality of twist needles may be used, mounted in a circular pattern around the circumference of the twist drum and sequentially indexed to be engaged with the twist belt or twist drum or drums while a drafted length of fibrous material is fed thereto. In this fashion a multi-ply yarn may be obtained. The central twist drum contains a hollow central shaft which permits the feeding of a yarn or other materials through the center of the central drum thereby permitting the building of a large multi-ply yarn.
