Definitions

  • the present invention relates to a method for setting a yarn at a desired tension during the unwinding and winding thereof.
  • the method is characterized in that the yarn, after unwinding from twisting or coiling members, passes between two spaced pairs of driven rollers rotating at dilferent speeds to provide a controlled overor under-supply of yarn on the straight path between the two pairs of rollers wherein the yarn is heated without any direct contact with hot solid surfaces.
  • the accompanying drawing shows apparatus for performing the method of the invention as applied to elasticized or texturized synthetic fibres.
  • FIGURE 1 shows a first apparatus of the invention in a perspective view and partly in section.
  • FIGURE 2 is an axial cross-section of a spool from which yarn is unwound in the apparatus of FIG. 1 under uniform tension and with the desired twist.
  • FIGURE 3 shows a modified device for producing the initial twist in the apparatus of FIG. 1.
  • FIGURE 4 shows a further modification similar to that of FIG. 3.
  • the apparatus shown in FIG. 1 comprises a spool 1 from which yarn is unwound while simultaneously being given a twist about its longitudinal axis under uniform tension.
  • the twisting operation causes a helicoidal arrangement of the fibres in the elasticized or texturized yarn that allows the yarn to vary its length without relative displacement of the fibres thereof, as would occur with fibres parallel to the direction of yarn elongation.
  • the yarn 2 is led by a thread guide 3 into the nip of a first pair of driven feed rolls 4-4, and is drawn from the first pair in a Straight path by a second pair of feed rolls 5-5 placed at a distance AB from the rolls 4-4.
  • the pairs of feed rolls 4 4' and 55 rotate at different surface speeds, to provide the desired overor under-supply of yarn on the straight length A-B.
  • the yarn is set while moving in the straight length A-B by being heated within a hot air chamber 8 at a uniform temperature.
  • the yarn is not in frictional contact with any hot solid i-atented lsiay 21, 1963 surface along the heating path A-B, but is merely hit by hot air or an infrared ray beam which does not change the shape of the yarn and does not disturb its fibre arrange ment. From the feed rollers 5-5 the yarn passes over a lubricating roller 6 and is wound on spools 7, ready for the next operation.
  • FIGURE 2 is an axial section of the spool 1 from which the yarn is unwound in a twisting step at very uniform tension.
  • a balloon is formed in the yarn 2v which draws the yarn from the spool 1 with a uniform force from whichever point the yarn is unwound.
  • FIGURE 3 illustrates a twisting assembly which may replace the spool 1 in the apparatus of FIG. 1.
  • a thread 10 unwinding from a stationary bobbin 9 is an upwardly axial direction through a tension member 11 passes to the rotating bellow spindle 17 of a bobbin 14 where it is joined by the thread 15 of the bobbin 14 which is unwound axially upward and passes through the spindle 17 from top to bottom.
  • a twisted and balanced yarn 19 is obtained and then passes through the feed rollers 4-4 and 55'.
  • a method of treating heat-settable yarn which comprises:
