Definitions

  • rotating draw-off aids do not permit the yarn running off a lower or rear package (on the spindle axis) to be guided past the upper or forward package (likewise related to the spindle axis) without touching the sides of said package.
  • the problem is solved by providing .a flexibly yielding disc which is adapted to be mounted on the package spindle, and which is elastically deformable by the tension of the yarn sliding over its edge.
  • the diameter of the yielding disc should exceed the greatest diameter of the package or packages from which yarn is withdrawn.
  • the tension of the yarn during withdrawal applies a radial inwardly directed thrust to the edge of the disc.
  • This thrust deforms and deflects the proposed flexible disc until the reactive elastic resistance to deformation of the disc balances the radial thrust of the yarn.
  • the yarn thus runs over the edge of the disc maintaining substantially constant tension.
  • the disc may consist of plastic, of animal skin, particularly parchment, paper, for instance glazed paper, or of other suitable materials which need not here all be listed. Any materials are suitable provided they have the properties needed, particularly the required degree of elastic flexibility.
  • the invention proposes to pro vide an axially loosely mounted disc of smaller diameter than that of the disc forming the principal draw-off aid.
  • the auxiliary disc should be convexly shaped, the convex side of the auxiliary disc resting on the top of the package. This auxiliary disc will then guide the yarn to the withdrawing sheave and prevent it from snarling around the tubular core of the package.
  • the disc forming the draw-off aid must be elastic, there is some risk of the disc being deflected from the horizontal in the downward direction. According to the invention this possibility can be eliminated by providing mechanical support for the disc.
  • This may have the form of a ring which supports the peripheral edge of the disc.
  • a spider may be provided and preferably loosely mounted on the spindle holding the package.
  • FIG. 1 is a sectional elevation showing a device with a conical package
  • FIG. 2 is a sectional elevation of a modified device with two conical co-axial packages and showing a preferred form of disc.
  • FIGS. 3, 4 and 5 are views similar to FIG. 2 each showing a d-illerent modified form of disc.
  • FIG. 6 is a sectional elevation of discs according to the invention applied to a three-high package device.
  • FIG. 7 is a sectional elevation of a'fo-urhigh package device with somewhat modified discs.
  • FIG. 8 is a sectional elevation of the device shown in FIG. 1 and having an auxiliary disc.
  • FIG. 9 is a plan view which shows a spider for use with the auxiliary disc of FIG. 8.
  • FIG. 10 is a plan view of the modified disc of FIG. 8.
  • FIG. 11 is an elevation, partly in section which illustrates a two-high package spindle incorporating auxiliary discs and supports therefor.
  • FIG. 1 shows a cone 1 fnom which the yarn is withdrawn over top, for instance into the hollow interior 31 of a double twist spindle.
  • an elastic disc 3 made of plastic, animal skin, paper or the like.
  • the edge of the disc at 4 is upwardly deflected by the tension of the running yarn 2, the degree of deflection being determined by the point at which the inward radial thrust of the yarn is balanced by the reactive elastic resistance of the disc 3. Consequently the tension of the running yarn 2 will be continuously maintained at the same level, particularly in virtue of the fact that with decreasing package diameter point 4 will travel inwards. Consequently the tension which in conventional draw-off aids of constant diameter or of stepped diameter tends to change will be automatically kept in balance.
  • the disc 3 has a central hole permitting it to be mounted on the hollow spindle 31 when, as illustrated in FIG. 1, this is a double twist spindle.
  • the disc is correspondingly mounted on the package spindle or peg.
  • the disc has a stiffening reinforcement surrounding its cent-re hole and the reinforcement may naturally be integral with the disc.
  • the reinforcement may consist of a special ring cemented to the disc or it may consist of two loose rings 5 between which the disc is tightly held.
  • several discs of smaller diameter than disc 3 may be placed on the latte-r and the reinforcing discs may all have the same or different diameters.
  • the diameter of disc 3 should exceed the greatest diameter of the package at 6. For modifying the effect of the disc 3 two or more similar dis-cs may be superimposed.
  • the proposed disc 3 may also be used for unwinding a cheese.
  • the presence of the disc effectively prevents the running yarn 2 from being dragged over the edge 7 of the package.
  • the yarn cannot therefore become caught in the upper layers of yarn near the edge of the package and the tension of the running yarn cannot be affected by changes in friction of the yarn as it rubs on the peripheral surface of the package, because the ring holds the yarn clear of the package.
  • FIG. 2 shows two packages 8 and 9 mounted on one spindle.
  • the disc 3 according to the invention is interposed between the packages and its edge is deflected as indicated at 4 by the yarn unwinding from the lower of the two packages.
  • the edge of the disc 3 curls over more and more until it is finally deflected into contact with the bottom edge 10 of package 9. This effectively prevents the yarn 2 from being dragged over the edge of package 9.
  • a disc 3 would also be provided for guiding the yarn unwinding from package 9, as illustrated in FIG. 1, but for the sake of clarity this is not specially shown in FIG. 2.
  • the discs 3 may be advisable to construct the discs 3 in such a Way that their thickness uniformly decreases from the centre to the periphery.
  • the mechanical rigidity and stability of the disc in region 11 will thus be improved, whereas in region 12 the disc will be particularly flexible, elastic and yielding.
  • the edge of such a disc 3 may be provided with a reinforcement, as illustrated at 13 in FIG. 3. Whilst preserving the required elasticity of the disc in the marginal region the edge itself is rendered more resistant and any danger of the yarn cutting the edge of the disc is eliminated. Otherwise this embodiment is similar to that illustrated in FIG. 2.
  • FIG. 4 substantially corresponds to FIG. 2, but the edge of the disc 3 is here slightly dished, as indicated at 14.
  • FIG. 5 illustrates a disc Which is mechanically reinforced by the provision of concentric corrugations 15. As indicated at 16 the corrugations also serve for centering the tubular core 17 of the upper package 9 as Well as the core 18 of the bottom package. The two cores 17 and 18 can thus be slightly telescoped and the overall height of the assembly reduced. The arrangement functions in exactly the same way as described by reference to the other illustrations.
  • FIG. 6 exemplifies the application of the proposed draw-off aid in a three-high assembly of packages for a double twist spindle, suitable for instance for unwinding from flat cheeses 19, 20 and 21 for doubling three yarns.
  • Discs 3 are intenposed between the several packages, the yarns riding over the disc edges and deflecting them upwards as indicated at points 4.
  • FIG. 7 is a fourhigh assembly of cross-wound cones 22, 23, 24, 25 as required for multiple twist spindles, creels, looms and like textile machines.
  • Discs 3 are interposed between each of the packages.
  • the discs have reinforced centres 26 which also serve for centering the core of the next package above, and which similarly serve for centering the core of the package underneath.
  • FIG. 7 exemplifies an arrangement in which the pack ages are mounted on a central tube or hollow peg 27 in a manner which would otherwise be impossible.
  • the packages are supported by the disc reinforcements 26 and held in position by an overhead spring 28 and a push-on and turn cap 29, 30.
  • An arrangement of such a kind may be used for instance for creels, battery frames and the like.
  • the provision of the discs 3 permits overend yarn withdrawal from the several cones 22 to 25 to proceed cleanly and smoothly. In cases in which, as in FIG. 7, it is necessary to withdraw yarn from four packages, this could hitherto not be done otherwise than over rollers, or the several packages had to be mounted side by side, an arrangement which requires a particularly large amount of space. It will be readily understood that the arrangement exemplified in FIG. 7 is not limited to a four-high spindle and that more packages can be readily added if necessary.
  • the arrangement may be modified as illustrated in FIG. 8.
  • the yarn 102 is drawn 01f the package 101 and taken through the hollow spindle 103.
  • a flexible yielding disc 104 is provided as a draw-0E? aid, the pe riphery of the disc being elastically deformable by the yarn running over the edge.
  • the disc is loosely mounted on the spindle and is therefore capable of being rotatably entrained by the yarn 102. Consequently, Whenever the deforming disc offers the yarn a slightly increased resistance this is easily compensated by the disc being temporarily rotatably entrained.
  • the disc is formed with an undulating peripheral serration.
  • the undulation has the advantage in double wound packages that the doubled yarn will run through a valley 105 and that the two threads will thus be held together until they enter the hollow spindle 103. Naturally the provision of a single notch or undulation may sometimes be suflicient.
  • auxiliary disc 107 is loosely mounted on the spindle 103.
  • This auxiliary disc 107 has a convex underside which bears on the top of the package 101.
  • This disc 107 which may likewise participate in the rotary motion of the yarn guides the yarn cleanly on to the principal disc 104.
  • a disc of the proposed kind must be elastically flexible but it must not be defiectable downwards beyond the horizontal because kinks may then form, in which the yarn may get caught, and other troubles may also arise.
  • the central part of the disc as far as to a suitable radial distance from the elastically flexible margin may be provided with a reinforcement for instance in the form of corrugations, thickening of the gauge of the material, and so forth.
  • a reinforcement for instance in the form of corrugations, thickening of the gauge of the material, and so forth.
  • support is provided by a spider 108 as specially shown in FIG. 9.
  • the hub 109 of the spider 108 permits the latter likewise to be loosely threaded on to the spindle 103.
  • the spider is therefore also capable of being entrained by the rotating yarn.
  • the result of the provision of a spider of the kind shown in FIG. 9 in conjunction with a serrated disc according to FIG. 10 will be readily understood by reference to FIG. 8.
  • the yarn 102 deflects the edge of disc 104 and runs through a valley 105 between two neighbouring lobes of the undulation. At the same time the yarn will travel upwards between two arms of the spider 108.
  • the disc 104 as well as the spider 108 participate in the rotation of the unwinding yarn.
  • FIG. 11 is a two-high arrangement comprising a lower cone 110 and an upper cone 111.
  • a disc 112 is provided as a draw-oif aid for the yarn withdrawn from the lower cone.
  • a ring 113 is provided which is attached by radial stays 114 to the upper part 115 of the external protective cage.
  • 116 is the lower part of the protective cage upon which the upper part 115 rests. In this arrangement it is likewise advisable to provide auxiliary discs 11W.
  • either one or both sides of the discs may be provided with a conducting coating, for instance by metallisation, for dissipating static electrical charges which may otherwise build up by the friction.
  • a conducting coating for instance by metallisation
  • the metal spraying technique is particularly convenient.
  • the discs may be provided with a graphite coating or alternatively metal or graphite may be incorporated in the material of which the discs are made.
  • a device for supporting a yarn package for the overend withdrawal of yarn from said package comprising an elastically yielding disc arranged so that the margin of the disc is deformable by the tension of the yarn running across the periphery of said disc.
  • a device comprising a spindle and in which the said disc is loosely mounted on said spindle so as to be capable of being rotated by the rota tional movement of the running yarn.
  • a device in which the said disc is of paper, particularly glazed paper.
  • a device in which the said disc has a central hole and is reinforced in the region of its said hole.
  • a device in which the disc comprises a central reinforcing ring adhesively attached thereto.
  • a device according to claim 1 comprising two loose rings clamping the said disc between them.
  • a device for the withdrawal overend of yarn from packages of yarn comprising a spindle upon which a plurality of yarn packages may be arranged in co-axial relationship, and at least one flexible yielding disc mounted on said spindle in such a position that yarn coming from a said package can pass across the periphery of said disc, said disc being provided with a reinforcing ring arranged to support the end of a tubular core of the package above, the margin of said disc being elastically deformable by the tension of the yarn running across the periphery of the disc.
  • a device in which the thickness of the said disc decreases radially outwards.
  • a device in which the margin of the said disc is slightly upwardly dished.
  • a device according to claim 1 comprising mechanical support means for the said disc.
  • a device comprising a ring for supporting the peripheral edge of the disc.
