Definitions

  • the yarn coming from the bobbin is being guided and set rotating about the bobbin axis, when travelling overhead and traversing the center of the bobbin by a wire guiding the yarn and putting it under tension.
  • Twisting fliers of this kind are however not adapted for use when twisting very fine yarn, more especially if cops serve as bobbins, because they impart, owing to their great weight and the considerable friction arising in their bearings, an unduly high tension.
  • These drawbacks are felt quite particularly when the twisting spindle shall be started working and the twisting flier shall be accelerated from the position of rest of the yarn. If the yarn coming from the bobbin is prevented from easily following the flier, it has a tendency of braking the further movement of the flier.
  • the problem to be solved by the present invention is to provide a yarn tension appliance for twisting spindles, more especially of the cabling type, which while avoiding all the drawbacks mentioned above, guarantees a correct drawing of the yarn to be twisted from the bobbin, for instance a cop, and imparts to the thread, owing to its extraordinary sensitivity, a small and uniform tension.
  • this wire which guides and puts under tension the yarn coming from the bobbin, when it travels overhead and through the center of the bobbin, this wire being set rotating around the bobbin axis by the yarn.
  • this wire On the whole this wire has the form of a bow, one of its shanks being inserted in a tubular yarn guide arranged on top of the package sleeve, with enough play as not to aflfect the passage of the yarn.
  • the other shank of the wire which is formed with a guiding eyelet and rotates around the bobbin, is formed with a deflected portion directed toward the yarn guide and is supported partly by a shoulder provided on the yarn guide and is thereby braked to a certain extent, without, however, contacting that part of the yarn guide over which 2,762,583 Patented Sept. 11, 1956 the yarn is passing, so that there is no danger that the yarn might get pinched.
  • the guiding eyelet is formed on a deflected terminal portion of the exterior Wire shank, this deflected portion extending in one or the other direction in the circular path it traverses during rotation of the guide wire.
  • tensioning wires of different Weights may be used and the two shanks of such a wire may be capable of an elastic deformation so that it can pass over the correspondingly formed flanged part of the yarn guide, while resisting any tendency of the wire itself or of the yarn to push it back.
  • weights may be provided which can be interchanged and are fixed removably tothe interior shank of the guide wire. In order to keep such weights on the wire by clamping, this may be slightly bent at the place or near the place where such a weight shall be located.
  • a permanent magnet may be arranged on the tubular yarn guide below the shoulder on which the guide wire is supported. This brakes the rotary displacement of the deflected wire portion on the exterior shank which abuts against the shoulder.
  • the braking action of the magnet on the wire can be varied by changing the position of the magnet by means of displaceable disks.
  • I further'propose to clamp the yarn guide to the package sleeve.
  • the clamping of the tensioning member on the package sleeve may be obtained by means of an elastic member such as a rubber ring or a spiral spring.
  • Such an elastic means may be embedded in. an outward groove of the yarn guide and clamps the wire in this groove across openings in the groove.
  • I may, however, also provide the yarn guide with a resilient, e. g., slotted bottom portion.
  • the yarn guide In order to avoid the necessity of lubricating the tensioning wire at the different places where it contacts the yarn guide and in order also to avoid any soiling of the yarn, I intend to form the yarn guide as a whole or partly of synthetic linear superpolyamides. I have found that this material, apart from its great gliding capacity, also offers the advantage of being to a great extent proof against rubbing and this is quite particularly important for the part of the yarn guide where the yarn comes into contact with it. To the same end I may arrange in this part of the yarn guide a cap made of a material which is wear-proof, for instance steel covered with a hard chromium cover and highly polished.
  • Fig. 1 is-an axial section of the yarn guide and package sleeve With the guiding and tensioning Wire inserted in it,
  • Fig. 2 being a top view of this .device.
  • Fig. 3 illustrates a second form of the invention in axial section, showing the yarn guide inserted in the package sleeve.
  • Fig. 4 is a top view of the device shown in Fig. 3.
  • Fig. 5 is another modification of the invention, again shown in axial section, and
  • Fig. 6 is a cross-section on the line AB in Fig. 5.
  • the interior shank of the wire is inserted with sufi'icient play in the yarn guide 2 for rotation therein, and the exterior shank 6 of the wire is formed with a deflected portion or knee 7 directedtoward the yarn guide 2 and supported by a shoulder 8, being capable of rotating with a certain braking action around the yarn guide, while not contacting the mouth of the yarn guide, thus securing a safe guiding of the yarn.
  • the eyelet 10 of the wire 4 is placed at the bent end 11 of the arm 6 of the wire.
  • the end 11 of the wire is bent at an angle in one or the other direction to extend in the circular path through which rotates this end of the arm or shank 6.
  • I may influence and vary the tension of the yarn 3 by using guide wires of diflerent weight or by providing the wire with weights 13 which can be clamped on it. I can further influence the yarn tension by arranging below the shoulder 8 underneath the rotating arm 6 a permanent magnet 14 which exerts a braking efiect on the arm 5 of the wire. This braking effect can be varied by means of disks 15 which surround the yarn guide and serve for adjusting the position of the magnet.
  • the yarn guide 2 can be mounted on the tube 1 by means of an elastic ring 17 which is embedded in an outer notch 16 of the yarn guide 2 and is applied to the tube 1 across interruptions in the notch 16.
  • This may be a rubber ring or a spiral spring.
  • the bottom portion may be rendered elastic by slots 19 (Fig. 1).
