Definitions

  • the invention relates to a thread guide arm with thread guide members arranged above the thread guide nut on the arm.
  • thread guide eyelet attached to the thread guide arm as thread deflecting element. Since a thread can be fed to the thread guide either from the left or from the right, a thread deflection eyelet is attached to a holding arm which projects beyond the thread guide arm on each side of the thread guide arm. Often a further thread guide eyelet is attached to the thread guide arm, the eye axis of which is aligned with the direction of movement of the thread guide and through which a thread intended for another thread guide can be guided for support.
  • thread guide organs have the disadvantage that a thread is formed in the event of tension fluctuations in the guided threads and a thread sag that may occur as a result can get caught on the outside of the thread guide eyelet or on its support arm, which leads to a thread break.
  • the object of the invention is to design the thread guide members arranged on the thread guide arm in such a way that no thread can get caught on them.
  • the object is achieved according to the invention in that, in the case of a thread guide arm of the type mentioned at the outset, the thread guide members are arranged directly and without a gap in front of a thread holding plate, the outer edge of which runs without an acute angle.
  • the thread-holding shield prevents a thread loop from being able to wrap around a thread guide element, and it is designed in such a way that no thread and no thread loop can attach itself to it, but must slide off its edge.
  • the thread guide members can consist of eyelets or bores which are inserted or formed in eyes or webs placed on the thread-holding shield and whose exposed edges are rounded or flattened.
  • the webs provided with thread guide bores or eyelets are formed in one piece with the thread holding plate.
  • the thread-holding plate can expediently be manufactured with the thread guiding elements as an investment casting and be provided with an abrasion-resistant coating.
  • the thread-holding shield can have a largely circular outer edge, but can also be composed of circular-arc sections and straight-line edge sections in such a way that there are no acute angles on its edge at which a thread or a thread loop could become caught.
  • the thread-holding plate can have a recess on its back that is suitable for receiving the arm, so that its rear forms a flat surface with the back of the thread-guiding arm and protrusions or gradations are avoided on which threads could become caught.
  • FIG. 1 shows a top view schematically of a thread guide 10 for a flat knitting machine, which is adjustably mounted parallel to the needle beds on a thread guide rail, not shown.
  • the thread guide 10 carries a rigid or pivotable, flat and blade-like thread guide arm 11, at the end of which there is also a flat nut 12 with a through hole 13 for a thread 14 to be presented to the needles of the flat knitting machine.
  • the thread 14 is fed to the nut 12 via a thread guide eye 15 which is arranged on the thread guide arm 11 together with two additional thread guide eyes 16 and 17.
  • the other thread guide eyelet 16 serves as a thread deflecting eyelet for a thread that can be fed from the other side of the thread guide.
  • the thread guide eye 17 serves as a support eye for a thread 19 guided in the thread guide adjustment direction 18 to an adjacent thread guide 19, not shown.
  • the three thread guide eyes 15, 16 and 17 are formed in the webs of a thread guide star 20 as bores, which are arranged in front of a thread holding plate 21 and made in one piece with it from metal investment casting and provided with an abrasion-resistant coating.
  • the thread holding plate 21 has the shape of a flat disc with a largely circular edge 22. Only at its lower point does it have a straight edge portion 22.1 which extends across the width of the thread guide arm 11.
  • the thread holding plate 21 is provided with a wide groove 23, whose width corresponds exactly to the width of the thread guide arm 11 at the fastening point of the thread holding plate 21 and whose depth is kept according to the sectional view according to FIG. 4 so that the flat thread guide arm can be fully immersed in the groove 23.
  • the thread guide star 20 arranged on the thread holding plate 21 with its three star webs having the three thread guide bores 15, 16 and 17 has rounded edges everywhere, on which no thread can get caught.
  • a stepped through bore 24 is formed for the recessed arrangement of a fastening screw 25 shown in FIG. 1.
  • Fig. 5 again shows the thread holding plate 21 according to FIGS. 1 to 4 with its largely circular outer edge 22.
  • Fig. 6 shows a thread holding plate 21 ', the outer edge of alternating circular arc sections 26.1, 26.2, 26.3 and rectilinear edge sections 26.4, 26.5 and 26.6 is composed.
  • Fig. 7 finally shows a thread holding plate 21 ⁇ , in which the edge consists mainly of three arc sections 27.1, 27.2 and 27.3, which are connected to each other at the web ends of the thread guide star by short straight sections 27.4, 27.5 and 27.6.
  • the thread guide star 21 is designed as a three-armed star. Through the rectilinear edge portions of the thread holding shields 21 'and 21 ⁇ , a thread can be inserted more easily into the thread guide eyelets 15-17.
