Definitions

  • This invention relates to an apparatus for taking up a synthetic filamentary yarn spun or extruded from a spinneret.
  • the no-godet winding system has another drawback in that the reciprocative motion of the traverse 5 guide exerts a direct influence on the as-spun non-solidified filament yarn in the melting zone just below the extruding orifice of the spinneret in a melt-spinning process, resulting in a periodic unevenness along the length of the yarn corresponding to the period of the 0 reciprocative motion of the traverse guide.
  • the present invention provides an improved apparatus for taking up a filamentary yarn extruded from a spinneret, in which the effects of the reciprocative motion of the traverse guide on the as-spun yarn in the melting zone directly below the extruding orifice of the spinneret can be completely elminated so that the resultant yarn has substantially no periodic unevenness corresponding to the motion of the traverse guide.
  • the apparatus according to the present invention also results in a desirably shaped yarn package because of its - tension controlling capacity.
  • an apparatus for taking up a filamentary yarn continuously extruded from a spinneret onto a yarn package comprising
  • Figs. 1 and 2 illustrate a multi-cop type spindle drive winder embodying the present invention.
  • Four filamentary yarns Y melt-spun from a spinneret 1 travel downward to a take-up apparatus 10.
  • spinning oil is applied to each yarn Y by an oiling roller (not shown) in a conventional manner.
  • Each yarn is the taken up as a yarn package 8 on a bobbin 7 fitted on a driving spindle 6 of a winder 4 through reciprocative motion of a traverse guide 5 along the axial direction of the yarn package.
  • Reference numeral 20 designates a pressure roller which assists in controlling the package shape.
  • This take-up apparatus 10 is provided with a tension control means comprising a cylindrical feed roller 3 located downwardly of the winder 4 and driven by a motor 21.
  • the yarn Y passes over the feed roller 3 prior to being introduced to the traverse guide of the winder 4.
  • the yarn Y extruded from the spinneret 1 travels free of contact with objects causing positive movement of the yarn until received by the feed roller 3.
  • the yarn touches the oiling roller or a yarn guide 11 for changing the yarn passage as.shown i in Fig. 1.
  • the direction of travel of the yarn Y changes from downward to upward.
  • the yarn is wrapped half around the feed roller 3.
  • This wrapping 5 of the yarn on the roller 3 prevents the tension-in the downstream portion from affecting that in the upstream portion and vice versa.
  • the yarn tension downstream of the feed roller 3 can be controlled to one suitable for forming a desirably shaped package, irrespective of the higher yarn tension upstream, by controlling the driving speed of roller 3.
  • the yarn tension downstream of the feed roller 3, which varies periodically due to the reciprocative motion of the traverse guide 5, is prevented from affecting the yarn tension upstream thereof, whereby the tension variation due to the traverse guide 5 can be prevented from influencing the non-solidified yarn in the melting zone.
  • the feed roller 3 may be installed at a fixed position relative to the winder 4; however, it is preferably made adjustable in position in accordance with the types of the yarn to be wound or the take-up speed.
  • any type of conventional winder can be utilized for the present invention, such as a single-cop type or a multi-cop type; a surface-drive type or a spindle-drive type; or a single spindle type or a revolving type having two spindles, in which, as shown in Figs. 3 and 4, two spindles 6a and 6b secured on a rotatable arm 9 are alternately located at a first position 6a where the yarn package is developing and at a second position 6b where doffing and donning of the yarn. package are carried out by revolving the arm 9, whereby continuous winding can be performed without cut-down of the yarn.
  • The.number of feed rollers is not limited to one as shown in the drawings, but may be two or more so long as they are located downward of the winder.
  • the ratio L/l of a distance L between the traverse guide 5 and the feed roller 3 relative to a stroke l of the traverse guide 5 is preferably within a range of from 3 to 15, more preferably from 4 to 6.
  • the ratio is desirably as large as possible.
  • increase of the ratio means a longer distance L. This increases the size of the overall installation and, in turn, the difficulty of machine operation. Accordingly, the ratio should be less than 15.
  • a fulcrum yarn guide 12 (Figs. 1 and 2) may be provided between the traverse guide 5 and the feed roller 3 at the center of the traverse motion of the yarn.
  • an interlacing means such as an air nozzle 13 (Figs. 1 and 2), may be provided between the fulcrum guide 12 and the feed roller 3. Since the yarn tension in this zone can be kept sufficiently low, the filaments of the yarn Y can be interlaced with each other in favourable conditions by the air nozzle 13 to form a compact yarn.
  • the feed roller 3 may have an outer surface of satin finish plating for providing a suitable surface for controlling the yarn tension.
  • the surface is provided with a plurality of alternate satin finished portions 14 and mirror surface portions 15 arranged in the axial direction of the roller, as shown in Fig. 5.
  • the surface may be provided with a plurality of grooved portions 16 as shown in Fig. 6.
  • the ratio of the width of the satin finished portion 14 or of the grooved portion 16 relative to that of the remaining portion is preferably within a range of from 1:2 to 1:7.
  • the feed roller 3 may consist of a plurality of large diameter portions 3a having relatively narrow width corresponding to the yarn receiving positions as shown in Fig. 7.
  • a yarn tension within a range of from 0.05 g/d to 0.3 g/d, preferably from 0.1 g/d to 0.2 g/d, can be attained at a position between the feed roller 3 and the traverse guide 5 by the apparatus according to the present invention. This tension is optimal for forming a good shaped yarn package.
  • the apparatus according to the present invention may be operated at a yarn speed on the feed roller of not less than 4,000 m/min.
  • a uniform yarn quality and a desirably shaped yarn package can be obtained because the reciprocative motion of the traverse guide necessary for forming the package is prevented from influehcing the tension at melting zone just below the discharging orifice of the spinneret and because the yarn tension-can be controlled to a suitable level for package winding.
  • the feed roller can be positioned close to the floor. Since the height of an overall installation is substantially determined by the distance between the feed roller and the spinneret, this results in a more compact installation.
