Definitions

  • This invention relates to a process for winding filamentary and yarn materials and to the yarn package produced therefrom. More particularly, the invention relates to a yarn winding process wherein a regularly cycled traverse speed fluctuating about a constant average value is employed to effect a uniform yarn winding pattern permitting packaging larger than conventional yarn packages free or" primary and lower order ribbons.
  • ribbon refers to a build-up of superimposed yarn windings or convolutions laid approximately one on top of the other which is characteristically formed at periodic intervals in a package of yarn wound on a yarn holder, bobbin, tube or the like by conventional yarn winding practices.
  • the formation of ribbons in yarn packages is undesirable and disadvantageous.
  • the yarn convolutions slide or slough from and trap on the bobbin causing uneven takeoff tensions and consequent streaking in the fabric both in the griege and dyed states.
  • Tension variations are also inherent in the yarn within the package when severe ribbons are present.
  • yarn is delivered from a spinning, drawing or other zone at a preselected speed to a take-up bobbin operatively driven by conventional means at a constantly variable rate of speed but maintaining a constant peripheral rate of speed for collecting the yarn at a constant rate of speed.
  • a take-up bobbin operatively driven by conventional means at a constantly variable rate of speed but maintaining a constant peripheral rate of speed for collecting the yarn at a constant rate of speed.
  • traversing means such as a reciprocable guide or a traverse groove roll at a constant rate of traversal.
  • the rate of traverse of the yarn is 500 traversals per minute (t.p.m.), each traversal being equivalent to a back and forth displacement of the yarn across the bobbin by the traverse device; that the bobbin is four inches in diameter and that the bobbin is driven initially at 1,900 revolutions per minute (r.p.m.) and the r.p.m. progressively decreases for maintaining a constant peripheral bobbin rate of speed.
  • the yarn is packaged to a size where the total bobbin and package diameter equals eight inches the bobbin r.p.m. decreases to 500 r.p.m.
  • the ratio of the traversal rate to the bobbin speed at any one time during the winding process will herein be referred to as the ribbon ratio.
  • the ribbon ratio as start-up in the above example therefore is 50021000 or 1:2 and at completion 500:500 or 1:1 with an infinite number of ribbon ratios established therebetween.
  • the ribbon ratio progressively increases from start-up to completion. It will be noted that at a ribbon ratio of 1:1 one traversal of yarn is made for each bobbin revolution and that at a ribbon ratio of 1:2 one traversal of yarn is made for a corresponding two revolutions of the bobbin.
  • the rate of traversal is controlled at a value below the bobbin r.p.m.
  • this procedure causes the yarn to be wound at a non-uniform tension.
  • a yarn is delivered at a preselected rate of speed to a yarn carrier such as a bobbin adapted to be driven at a varying decreasing rotational rate of speed or r.p.m. but maintaining a constant peripheral rate of speed for taking up the yarn at a constant rate.
  • the yarn traveling to the bobbin is then displaced or traversed across the face of the bobbin at a regularly cycled speed fluctuating between a maximum positive value and a maximum equal negative value about a predetermined constant average traversal rate of speed and at a predetermined frequency to elude ribbon forming ratios.
  • the yarn is packaged on the boibbin beyond the point where the bobbin rate of speed and the average traversal rate of speed bear a 1:1 ratio while always maintaining said average traversal rate of speed constant for forming a large ribbon free yarn package.
  • FIGURE 1 is a schematic perspective view showing the novel winding process operated by appropriate textile draw winding equipment
  • FIGURE 2 is a graph showing bobbin r.p.m. and yarn traversals per minute as a function of time and further illustrating the particular traversing cycling sequence in accordance with the invention
  • FIGURE 3 is a developed plan view showing the traverse of yarn on a bobbin typifying the pattern of a primary ribbon;
  • FIGURE 4 is a developed plan view showing the traverse of yarn on a bobbin typi-fying the pattern of a secondary ribbon;
  • FIGURE is a developed plan view showing the traverse of yarn on a bobbin typifying the pattern of a tertiary ribbon.
  • FIGURE 1 The novel winding process embodying the invention is illustrated in FIGURE 1 in conjunction with textile draw winding apparatus for carrying out the process.
  • the yarn 1 such as nylon, extends from a suitable source thereof, for example cake 2, to a guide 3 and then to a feed roll assembly consisting of a driven feed roll 4 and a nip roll 5.
  • the yarn is nipped between rolls 4 and 5 which are in surface engagement therebetween and is forwarded to a draw roll 6.
  • the feed roll 4 is driven at one rate of speed and the draw roll 6 is driven at a higher rate of speed to stretch the yarn therebetween.
  • a draw pin 7 is normally interposed between rolls 4 and 6 in the yarn path and one or several wraps are taken around pin 7 for localizing the attenuation of the yarn.
  • a traverse guide such as a driven traverse groove roll 9 and is laced within the traversing groove 10 formed about the circumference of roll 9 for traversing the yarn before the yarn is collected on a bobbin 11.
  • Bobbin 11 is surfacely driven by a drive roll 12 powered by a motor 13 and is mounted on a shaft connected to one end of a lever 14 which is pivotally mounted at its opposite end.
  • the drive roll 12 is driven at a constant speed and the bobbin 11 is driven at a progressively decreasing rate of speed inversely proportional to the increase in the diameter of the yarn package being wound on the bobbin.
  • the bobbin 11 is driven so as to achieve a constant peripheral rate of speed.
  • Traverse groove roll 9 is driven through a shaft 15 connected to a standard type variable speed drive unit 16 that includes a controller 17 for sending a timed cycling signal to unit 16.
  • the speed of shaft 15 can be varied over a wide range and controller 17 is adapted to permit cycling within specific desired ranges.
  • Controller 17 may be provided with potentiometers that control the acceleration and deceleration rates and the amplitude within a selected cycle period, or suitable cam type controllers may be provided.
  • Such a variable speed drive unit and controller are available as the Ajusto-Speed unit and controller from the Louis-Allis Company, Milwaukee, Wisconsin. I
  • draw roll 6 is driven at a speed for delivering the yarn to bobbin 11 at approximately 812 yards per minute (y.p.m.).
  • Bobbin 11 is initially driven at 1950 revolutions per minute (r.p.m.) as shown on the ordinate line of the graph for taking up yarn at approximately 733 y.p.m.
  • the take-up speed is lower than the delivery speed because of normal shrinkage of the yarn.
  • the bobbin rpm. decreases exponentially due to the increase in size of the package while the bobbin peripheral rate of speed remains at approximately 733 y.p.m.
  • Line 13 in the graph represents the speed of the bobbin with respect to time shown as a seven hour packaging winding period and represented on the abscissa line of the graph.
  • the traverse groove roll 9 is driven at a cycled traverse speed providing an average rate of traverse of 990 traverses of the yarn across the face of the bobbin per minute which is achieved by proper adjustment of unit 16 and controller 17 and is indicated by line 19 in the graph.
  • the groove roll 9 is cycled at a regular frequency of 6 cycles per minute with the traversal speed amplified to a positive m ximum of 1020 t.p.m. and to a ne ative maximum of 960 t.p.m. within each cycle in a saw-tooth pattern throughout the winding process.
  • the amplitude is :30 rpm. about the average traversal speed of 990 t.p.m.
  • acceleration-dcceleration and deceleration-acceleration reversal of each cycle be made substantially instantaneously to form a saw-tooth pattern as represented in the graph (FIG. 2) to obtain a maximum differential traversal speed for a selected cycle amplitude and frequency at a uniform rate.
  • Winding processes according to the invention may be operated successfully within cycling ranges of 25l00 t.p.m. above and below, respectively, a predetermined average traversal rate of speed, that is :(25400) t.p.m., with cycling periods within a range of 4-10 cycles per minute. At higher winding speeds it is preferable that a relatively high amplitude and high frequency value be selected within the ranges indicated.
  • the winding process embodying the invention yields ribbon-free packages which are not limited in size by the primary ribbon and which are wound at a uniform tension.
  • a yarn package having the yarn Wound under a uniform tension provides a yarn having a uniform shrinkage quality.
  • the invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others and the article possessing the features, properties and the relation of elements which are exemplified in the description given. It will be understood that the invention is not contemplated to be limited to the preferred embodiment and that variations may be made within the scope of the following claims.
