Definitions

  • a usual practice in spinning yarn is to draw the rovings in a. two-roller mule, and impart greater attenuation in a three-roller mule.
  • the object of my invention is to improve the uniformity, strength and fineness of the yarn and to insure that the twist is mainly at the circumferential part thereof; also to prevent back-twist, and secure greater tensile strength and stretchability.
  • the single yarns travel separately to the brake.
  • the twist given for doubling is in the opposite direction to the twist of the fibres, so that there is some untwisting of the yarn, which allows of stretching.
  • the delivery rollers a, a deliver loosely spun yarn b, which at 0 passes over a brake d, and thence to the spindle 6.
  • the greater part of the twist imparted by the spindle is confined to that part ofthe yarn which is between the spindle and the brake.
  • the spun yarn draws out fibre in proportion as the speed of the carriage exceeds the rate of delivery of the rollers.
  • the brake may be made vertically adjustable, for regulating its effect, or a larger or smaller brake may be substituted for the same purpose; these two regulating methods may be used in conjunction.
  • Fig. 1 shows a flat-topped brake across which the fibre runs from c to 0 I may also regulate the brake effect by vertically adjusting the rollers, leaving the brake stationary.
  • the process is similar to. that used for spinning from rovings, but thespindle e is rotated in the opposite direction to the twist of the partly spun yarn, with such excess of speed that the .part b leaving the rollers is untwisted.
  • the doubled yarn is in fact of a novel kind.
  • the doubling is permanent and independent of the direction of twist by which it is done, and of the twist of the separate yarns. Irregularities of thickness of the separate yarns, such as shown at h in Fig. 4, are entirely eliminated in the doubled yarn, whereas with other methods they cause inequalities such as shown at g in Fig. 4.
  • the distance between the rollers and as shown in Fig. 3, the methodbrake is made longer or shorter, according to the length of the fibres.
  • the methodof spinning textile fibers consisting in subjecting the fibers to a restraining influence adjacent the drawing rollers intermediate the latter and a mule spindle whereby the twist due to the rotation of the spindle is imposed preponderantly on the length of fiber intermediate the point of application of said restraining influence and the spindle, the length of spun yarn drawing fiber from behind the point of application of said restraining influence.
  • the method of doubling yarn fibers consisting in subjecting the yarn to a restraining influence adjaccnt the drawing or delivery rollers intermediate the latter and a mule spindle, and rotating the spindle in the oppositevdirection to the twist of the yarn fibers whereby the separate yarns are untwisted between the rollers and the point of application of the restraining influence, and adjusting the resistance of said restraining influence for controlling the longitudinal extent of the untwisting action.
