Definitions

  • ABSTRACT A method of and a tension-regulating device for the tighttwizting of a pair of non-twisting threads unwound from a bobbin or yarn package, wherein the threads are passed without twisting through a hollow spindle, are wound one or more times around an arm of the tensionregulating device and are then passed through the eye thereof. Within the spindle, the threads are stretched and are length -'equalized, the twisting being effected by the eye and a pair of drawing rollers feeding the twisted yarn to a yarn packageor bobbin upon which it is wound.
  • the invention relates to a method of tight-twisting a straight stretch of previously nontwisted threads by means of a hollow spindle and a tension regulator or limiter.
  • the main object of the invention is to use the whole length of the hollow spindle for a preliminary equalizing of the tensile stresses in the nontwisted threads.
  • Another object of the invention is to locate the point at which the deceleration of the threads occurs, in such a manner at the outlet of the hollow spindle, that it coincides with the geometrical axis of the spindle.
  • the nontwisted threads are unwound separately from the yarn package fixed on a hollow spindle. After the passage of the nontwisted threads through the hollow spindle they are decelerated by a tension regulating limiter mounted at the discharge side of the hollow spindle and are tighttwisted by the rotary motion of the spindle. In such manner the entire twisting process is divided into two sections, zones or stretches The first section zone or stretch extends from the unwinding point of the nontwisted threads on the yarn package to the tension regulating limiter means. In this first section, zone or stretch the threads remain untwisted.
  • the second section, zone or stretch extends between the regulating limiter means and the guide means provided to guide the twisted threads toward the wind-up or takeup winding on means.
  • the tension regulating limiter fixed-at the discharge end of the hollow spindle in such manner that an aye provided thereon is aligned with the geometrical axis of the hollow spindle, transmits the rotary motion of the hollow spindle to the threads. 'Thus the threads are tighttwisted.
  • the tension regulating limiter adjusts the tension of thenontwisted threads and provides some stretching andequalizing of the structure of the nontwisted threads.
  • FIG. I shows a shematic diagram of a device embodying the invention
  • FIG. 2 is a side elevation of the tension regulating limiter shown in FIG. 1;
  • FIG. 3 is a top plan view of the tension regulating limiter.
  • the threads are then passed around the arm 12 of a tension regulating limiter 8 and reach the receiving bobbin 10 through the drawing roller pair 9.
  • the nontwisted threads are wound around the arm 12 of the tension regulating limiter 8 as many times as is required for increased tension in the section, stretch or zone of the formation of the twists.
  • the twist rate is determined by the number of revolutions of the hollow spindle 1 and by the drawing velocity of the pair of rollers 9.
  • the deceleration of the threads through the tension regulating limiter 8 avoids a back transmission of twists to the section between the tension regulating limiter 8 and the unwinding point on the bobbin 3.
  • the threads unwound off from the bobbin form separate baloon 6 before entering the inlet opening 5, and because of the smaller drag in the cavity of the spindle the threads are stretched and their lengths equalized before entering the section of the formation of twists.
  • the tension regulating limiter 8 comprises an arm 12, a spiral shaped open eye 13 and a spring sleeve 11.
  • the axis of the spiral shaped open eye 13 identified to in FIG. 3 with the numeral 15 is perpendicular to the axis 16 of the spindle.
  • the nontwisted threads are wound around the arm 12 and then pass through the eye 13. The threads thus follow the direction of the axis 16, so that no baloon is formed immediately after the regulating limiter 8.
  • a device for the twisting of a pair of threads on a yarn package comprising a hollow spindle having an axis; means for receiving said yarn package and rotating same and said spindle concurrently about said axis, said threads being unwound from said yarn package and passing through said spindle; a tension-regulating limiter mounted at an end of said spindle and having a spring sleeve surrounding said end of said spindle, an
