Definitions

  • ABSTRACT OF THE DISCLOSURE A process for developing and a thread package hav n built up continuously staggered cross wound layers wlth narrow pitch lacing securing the layers. A multiplicity of laces are arranged on the periphery of the package by a longitudinally stable system of sub-division.
  • the process for-developing consists of arranging a cross winding path and continuously shifting the resultant layer formation to one side so that a conicity in the direction of shift develops and then continuing this point in cross wound fashion. Then the wide package layer is sub-divided over its entire width and also several times over its peripheral extent with divider elements which are attached to a longitudinally stable element over the full width of the package.
  • hanks are produced on winding machines, being so wound and divided into a greater or lesser number of skeins that in order to be unreeled from rotatably mounted reels they have to be taken off radially. That is to say, they must be drawn off in a tangential fashion, the reel being caused to rotate by the tension in the unwinding thread. This is the reason why, especially in the case of thinner and therefore weaker yarns, the hank weight has to be limited since otherwise the thread would break; even if the reel were started up very carefully and slowly, due to its small breaking strain the thread would be very liable to rupture if it had to set a large mass rotating. For this reason, the hank weight is limited by the breaking strength of the thread.
  • the subject of the present invention is a large package which is wound in a novel way and can have weights amounting to several kilograms for a single length of thread.
  • the most important feature of this package is that it does not have to be rotated in order to be unwound, it being possible instead for the thread to be drawn off at high speed in an axial direction from. the end of the stationary package.
  • the start of the cone can be executed in a variety of ways. In the example shown, it is done in the manner which is mechanically the most simple to produce. This will be explained in greater detail in the specific description and in relation to the drawing. Also, the crossing ratio must be adapted to the particular application and to the material being wound, but this will not be dealt with in any detail here.
  • tie-off arrangement made in this process, tie-off being done at narrowly spaced intervals, over the width, and being done in multiple fashion around the periphery.
  • the dividing elements of a tieotf be they solid elements or loops of thread, are associated with a longitudinally stable member in order to ensure that the spacing between said elements is maintained. This protects the winding layer against aberrations in the thread crossing pattern during processing, in order to ensure the best unwinding conditions subsequently. None of the tie-off arrangements so far known satisfy the present purpose, namely that of allowing axial with drawal of the thread.
  • FIGURE 1 shows a schematic illustration through a layer of the package, illustrating the development of the cone
  • FIGURES 2a-2b show an example of how longitudinally stable tie-off can be effected using a rigid divider
  • FIGURE 3 is a variant form, showing a semi-rigid divider
  • FIGURE 4 is a radial section through the package layer with'the needles pushed through the layer;
  • FIGURE 5 is an axial section through the package layer in the plane of the needles
  • FIGURE 7 is an axial section through the package layer 3 with the latter divided by threads in the form of tie-oil loops;
  • FIGURE 8 is a radial section through the package layer, showing clamping sections
  • FIGURE 9 is an interrupted longitudinal section through a wide package of the kind proposed in accordance with the invention.
  • FIGURE 10 is a section on the line X-X of FIG- URE 9.
  • FIGURE 1 it is schematically illustrated how the conical layer is formed.
  • the path of the criss-cross arrangement runs between A and B. ,This distance must be adapted to the nature of the thread material, and to the layer thickness. To form a cone, this path is continuously displaced towards the right in accordance with the yarn thickness.
  • Each full layer of thread is illustrated schematically in FIGURE 1 by a line of corresponding length. Each 'further length then runs down towards the right over the preceding layers.
  • the cone At the layer running from A to B, the cone is about half full, and at the layer running from A" to B" the cone is completed, and from that point remains unmodified with the subsequent winding on of further layers.
  • the package is then developed width-wise up to the last layer Y-Z and the Width is, in fact, arbitrarily determinable.
  • FIGURES 2a-2b a rigid divider element 3, 4 is illustrated in which the elements 3 of high grade steel wire are in the form of cohesive wire hoops. These hoops 3 are spot-welded to rigid channel sections 4. The entire arrangement 3, 4 can be inserted with its hoops from the outside through the package layer in the direction of the arrows, Whilst the package is still on the fingers of the winder.
  • the closure element consists of a guide piece 5a which carries a flexible high grade steel wire 51).
  • the closure element could equally well be some other device, however, such as a cord.
  • FIGURE 3 a ditferent embodiment of a divider element, having a flexible backing 6 of synthetic material such as polypropylene, is shown.
  • the same wire hoops 3 are used, but this time they are formed in situ in a plastic injection moulding.
  • Numerous embodiments of such rigid or flexible divider elements can be provided. These are exclusively for use on non-automatic winding machines, however.
  • the divider elements are formed by threads or cords, using special needles, being attached via the form loops to longitudinally stable elements and thus maintained at the proper spacings.
  • FIGURES 4 to 7 schematically indicate an example of how a tie-ofi arrangement of this kind can be produced.
  • the procedure here is that over the complete finger length of the winding machine, needles 8 with special hooks and butts are provided (being located in a needle bed like that of a flat-bed knitting machine, although this is not shown), and by means of a needle cam (not shown) the needles are actuated through their butts and forced thus from the outside through the package layer 2 so that their hooked heads 8 project in a straight line into the internal cavity.
  • a tie-off thread 7 coming from a reel is then passed, by means of a special leader element 9, and this is then attached to a clamping device (not shown) at the end of the row of needles.
  • each needle draws a loop of thread 712 (FIGURE 7) around the part of the package layer situated between it and its neighbours.
  • each needle forms a loop 7b around the package layer, and these loops are then commonly attached to flexible but longitudinally stable elements 16. These longitudinally stable elements prevent the package layer from distorting in the manner which would occur with any conventional kind of tie-off arrangement.
  • the roller spot-welding mechanism consists of a welding roller 17 and a mating roller 18 (FIGURE 6).
  • the entire welding device and the supply reels carrying the tapes 16, are guided on a 'slide along the row of needles or loops, and special head guides in slot form ensure that the two tapes at either side of the loops are in exact alignment with one another.
  • the welding roller is provided at specific intervals around its periphery with electrically heatable pipe 17a, which, by a combination of pressure and heat, produce the welds between the tapes. These weld points are at such intervals from one another that within each loop at least one weld is bound to occur. In order to ensure that this requirement is in fact met, the loops are previously spread out by a spreader plate 15 provided with teeth 15a.
  • the section of the welding tapes is so chosen that the tapes can be easily torn apart, rupturing the weld points, without themselves suffering any damage. In this way, when the package has been set up for unwinding, these more or less stifii tapes can easily be ripped apart.
  • the tie-oil thread 7 can then be pulled out of the package in one piece from one end.
  • the welding together of the two tapes can equally well be effected using the dielectric principle.
  • tapes could be connected together by sticking.
  • clips 19 of a suitable synthetic material could be employed, as FIGURE 9 shows.
  • the loops 7b are picked up on teeth at the precise proper intervals, and clamped in place by means of laterally disposed beads.
  • separating wedges 13 associated with a cutter device 14 are provided on the abutment strip 12 (FIGURES 5 and 7) between the ends of the package.
  • the wedge 13 is arranged so that when the strip 12 is urged in the direction of the arrow (FIGURE 5) first of all the bank ends are parted from one another to such an extent that the two end needles pass through freely when offered up. In this way, they each draw between package layer and cutter device similar loops 7b (FIGURE 7), the threads passing around the cutter device.
  • the tie-01f thread 7 passing along the full width of the winder machine is cut at the cutter devices so that the hanks are ready for separate removal.
  • the start and end threads of each package are also fastened to the stabilising elements.
  • These stabilising elements holding the ends are distinguished from the other stabilising elements of the package by a special colour coding. In this way, when the time for unwinding the package arrives, the start and end threads can be found straight away.
  • FIGURES 9 and 10 show the finished wide package on the fingers 1 of a winding machine, and in this example the rigid elements 3, 4 and 5 illustrated in FIGURES 2a and 2b, have been used for tie-off purposes.
  • the wide package is here still in the tensioned state, therefore.
  • several tied packages may be arranged adjacent to one another.
  • the finished packages 2 shown in FIGURE 9, are detached by radial retraction of the fingers 1, and removed from said fingers.
  • the result is achieved that the package remains stable throughout all process stages, the package layer not shifting or deforming, so that after processing the thread can be drawn oflf from the cone end in the axial direction, without any trouble at all.
  • a thread package comprising built up continuously staggered cross-wound layers, narrow-pitch lacing securing said layers, and a multiplicity of laces arranged on the periphery of said package by a longitudinally stable system of sub-division.
  • Process for developing a wide thread package comprising arranging a cross-winding path and continuously shifting the resultant layer formation to one side so that a conicity in the direction of shift develops, then continuing the layer formation beyond this point in cross-wound fashion, and then sub-dividing the arbitrarily wide package layer thus formed over its entire width and also several times over its peripheral extent with divider elements which are attached to a longitudinally stable element over the full width of the package.
