  • the invention provides a construction in which the tension on the threads as they are twisted by the two-for-one twister is uniform as they travel between the feed rolls in the twister and the stretching rolls because the tension is positively controlled by two sets of driven rolls, one leading the bundle of filamenu; to the twist-stretch zone and the other taking it away from said zone.
  • the use of the machine of the invention is advantageous where high tensioning of the balloon is needed.
  • the internal feed roll assembly easily threaded up and provides positive feed of the yarn, which controls balloon tension, thereby permitting more revolutions per unit time in the balloon. It may also he pointed out that in such an arrangement as that shown, for example in Figure l, the rolls inside the twister sembly determine the rate of feed of the filaments, while the speed of stretch roll determines the amount or de gree to which the filaments will be stretched. Since both of these sets of rolls are driven positively and in a definite relationship to each other, the degree of stretch is constantly under control. Further, the amount of twist is determined and controlled by the relationship the feed rolls inside the twister and the speed of the rotor. This relationship can be varied conveniently by a change gear arrangement in gear or" the twister. Hence, the instant invention provides an exceptionally high degree oi uniformity in the tension during drawing and twist formation and also provides means for positively correlating the twist, the stretch, and the feed of the filaments in a highly advantagwus manner.
