Definitions

  • This invention is concerned with improvements in or relating to the winding of synthetic textile filaments or yarns and particularly, though not exclusively, to the winding thereof after a drawing operation in which heat is applied thereto.
  • as-spun filaments obtained, for example, by solution or melt spinning a particular polymer, may be stretched or drawn in the solid state by passing the filaments between two pairs of rollers, known as the feed and draw rolls respectively, the peripheral speed of the draw rolls being higher than that of the feed rolls by an amount sufficient to impart the required amount of stretch to the filaments.
  • the feed and draw rolls two pairs of rollers, known as the feed and draw rolls respectively
  • the peripheral speed of the draw rolls being higher than that of the feed rolls by an amount sufficient to impart the required amount of stretch to the filaments.
  • drawn filaments of uniform denier it has been found convenient to localise the point at which the drawing takes place by passing the filaments around a snubber pin placed between the feed and draw rolls.
  • Filaments may also be heated on the run in other processes such as, for example, false-twist crimping and length stabilising processes.
  • the heating means usually comprises a plate or a tube.
  • a difficulty encountered in the heating of filaments on the run is that associated with threading up and start up of the process, since it is often desirable for technical reasons to thread-up with the parts of the apparatus stationary.
  • the difficulty can be overcome when the heating means is a heated plate merely by arranging that the yarn be held out of contact with the plate during threading-up and moved into contact therewith when the threading-up has been completed.
  • the heating means comprises a tube, through which the yarn passes, by a lengthwise gap or gate in the tube through which the yarn may be passed when the threading-up has been completed.
  • the aforementioned technique is no longer of assistance since attempts to cause the yarn, which may be moving at 1500 to 2000 ft./min., to be wrapped around the heating means frequently leads to threadline breaks.
  • means may be provided for maintaining a substantially even tension in the yarn sufiicient to maintain the traveller in motion for one revolution at a time, and which does not affect the winding of yarn onto the package in the normal manner.
  • a process for winding yarn onto a bobbin by a ring and traveller system in which the leading end portion of the length of yarn is wound onto a waste-receiving end portion of the bobbin on which the main length of yarn is not wound, comprising causing the bobbin to rotate at a lower speed than the normal winding speed, imparting a tension to the yarn in addition to the tension normally imparted by the ring and traveller system by means restraining the traveller from a normal free rotation around its ring during said low speed rotation of the bobbin and thereafter increasing the speed of rotation of the bobbin and freeing the traveller from said rotational restraint.
  • an apparatus for winding yarn onto a rotating bobbin having at one end portion thereof a waste-receiving area comprising a spinning ring carrying a traveller normally freely rotatable thereabout, said spinning ring encircling the bobbin and having its plane substantially at right angles to the axis of the bobbin, and being mounted on a reciprocating frame adapted to remain stationary in a position in which yarn is wound onto the waste-receiving area of the bobbin and means to restrain the normal free rotation of the traveller around its ring when the tension J in the yarn is substantially below that attained under normal winding conditions.
  • bobbin includes any suitable yarn package support.
  • FIGURE 1 is an elevation of one embodiment of the invention when employed on a machine adapted to draw a yarn using a heated snubbing pin.
  • FIGURE 2 is a plan view of the embodiment shown in FIGURE 1 along the line AA.
  • FIGURE 3 is an elevation of another embodiment of the invention when applied to a machine adapted to draw and simultaneously false-twist crimp a yarn.
  • an undrawn yarn for example a polyester yarn, from a supply thereof is wrapped a plurality of times around a feed roll 3 and a freely rotatable separator roll 2, passed around a heated snubbing pin 4 and then is wrapped a plurality of times around a draw roll 6 and separator roll 5 in the conventional manner.
  • the yarn is taken through a yarn guide 7 to a traveller 8 on a spinning ring 9 where it is wound onto the waste sleeve 10 of rotating bobbin 11.
  • a yarn restraining means in the form of a leaf spring 12 is fixed to a clamp 13 mounted on the machine frame 14. The top 15 of the spring 13 protrudes above the level of the ring when the latter is in position to wind yarn onto the waste sleeve 10 of the bobbin.
  • FIGURE 3 the invention is shown applied to an apparatus for the simultaneous false-twisting and drawing of a yarn such as is more fully described in the British Patent No. 890,053.
  • a yarn 21 taken from a supply thereof is passed once round the feed roll 22, twice round the heated snubbing pin 23 and thence to the draw roll 24 with flange 25.
  • the snubbing pin is set off from the draw roll so that the yarn in passing from the pin to the draw roll rubs against the flange 25 and has a false twist imparted to it.
  • the yarn makes 3 passes around the draw roll 24 and the separator roll 26 and is then taken through the yarn guide 27 to the traveller 28 in a spinning ring 29 whence it is wound onto the waste sleeve 39 of a rotating bobbin 31.
  • a leaf spring 32 is mounted on a block 33 which in turn is then mounted on the machine frame 34. The leaf spring 32 passes inside the ring 29 between the ring and the Waste sleeve and is adjacent to the former so that it contacts the traveller when the ring is, as shown in a position to wind yarn onto the waste sleeve.
  • the spring contacts the traveller and restrains it from moving round the ring thereby increasing the tension in the yarn between the bobbin and the draw roll.
  • this tension approaches that obtained in the threadline under normal running conditions the traveller bends the spring and passes over it to make a single revolution around the spinning ring.
  • tension in the yarn is lost and the spring prevents the traveller from making a further revolution until the tension in the yarn has increased to the required level again.
  • the spring strip therefore operates to have the same effect as in the embodiment described with reference to FIGURES 1 and 2.
  • the top most portion of the spring strip ' is below the lowest level reached by the spinning ring and therefore does not interfere with the winding.
  • the slow speed of wind-up during the threading-up process prevents yarn from being in contact with the heated snubber pin for suflicient time to cause undue degradation of the yarn and hence normal winding can be started without an excessive number of breaks occurring attributable to weakness in the yarn caused by degradation.
  • a leaf spring as a restraining means
  • any other suitable form of restraining means e.g. a pivotally mounted counter balanced rod or an annular rubber bush making frictional contact with the traveller when the ring is in the start-up position, may be employed.
  • a method for winding yarn onto a bobbin employing a ring and traveller system, said bobbin having a waste-receiving end portion onto which the leading end portion of the yarn is wound comprising, rotating the bobbin at a speed lower than the normal winding speed, imparting a tension to the yarn in addition to the tension normally imparted by the ring and traveller system by restraining the traveller from a normal free rotation around its ring during said low speed rotation of the bobbin and thereafter increasing the speed of rotation of the bobbin and moving the traveller from said rotational restraint.
  • a method according to claim 2 wherein the restraining means comprises a leaf spring.
  • Apparatus for winding yarn onto a rotating bobbin having at one end portion thereof a waste-receiving area comprising a spinning ring carrying a traveller normally freely rotatable therearound, said spinning ring encircling the bobbin and having its plane substantially at right angles to the axis of the bobbin and being mounted on a reciprocating frame, said frame being adapted to have a stationary position at which yarn is Wound onto the waste-receiving area of the bobbin, and means to restrain the normal free rotation of the traveller around its ring when the tension in the yarn is substantially less than that attained under normal winding conditions.
  • Apparatus according to claim 6 wherein the means acts on the portion of yarn between the traveller and the waste-receiving area of the bobbin.
