Definitions

  • Tailfingen both of Germany [73] Assignee: Meyer 6: Cie, Tailfingen, Germany [22] Filed: Aug. 4, 1969 211 Appl. No.: 662,119
  • ABSTRACT A yarn guide particularly for guiding the yarn of a knitting machine.
  • the yarn guide includes a yam-guiding member formed with at least one passage through which the yarn is guided.
  • This member is composed at least in part of a ceramic material, and preferably it is in the form of a single body of pure ceramic material.
  • the present invention relates to knitting machines. In par ticular the present invention relates to yarn guides for these machines.
  • Yarn guides for knitting machines and for circular knitting machines serve the purpose of directing the yarn which is to be knitted to the needles at the knitting location in such a way that the yarn will be properly engaged by the needles, such yarn guides have the additional purpose of causing the closing or opening of those needle tongues which become free of the old loops and are partly open.
  • the wearing away of the yarn guide during formation of grooves in which the yarn itself moves sometimes situates these grooves at lateral locations which shift the yarn undesirably from the proper position of the yarn where it is fed into the needles, so that as a result there is a defective formation of loops during the knitting operation.
  • the yarn guiding assembly includes a yarn-guiding member formed with one or more yam-guiding passages and made of a material which is at least partly ceramic.
  • a yarn-guiding member formed with one or more yam-guiding passages and made of a material which is at least partly ceramic.
  • connection between the ceramic yarn-guiding member and the metallic mounting member with. the required accuracy and with a reliable prevention of breaking of the ceramic material is brought about in accordance with the invention by providing for the ceramic yarn-guiding member and the metallic mounting member interlocking configurations in the form, for example, of an elongated groove of the metallic mounting member which receives an elongated portion of the ceramic yarn guide which mates in cross section with the cross section of the groove.
  • the configuration of the groove of the metal mounting member and the elongated portion of the ceramic yarn-guiding member received therein is such that the assembly and disassembly of these components can only take place by longitudinal movement of the elongated portion of the ceramic yam-guiding body along the groove of the metallic mounting member.
  • the yarn-guiding member be made entirely of a pure ceramic material. Instead it is also possible to make the yarn-guiding member of a ceramic-containing material such as a metal alloy which contains ceramic ingredients. Such alloys are known as Cermet materials.
  • FIG. I is a schematic side elevation of a yarn guide of the invention.
  • FIG. 2 is an end view of the yarn guide of FIG. I as seen from the left of FIG. I at an angle of 9(] with respect thereto in the direction of rotary movement of the needle cylinder of a circular knitting machine.
  • the yarn guide of the invention which is shown more or less schematically in the drawings is particularly designed for use in a circular knitting machine.
  • This yarn guide has a mounting means in the form of a metal mounting; member It) made of steel and having a downwardly directed open groove at its bottom end.
  • This mounting means Ill has a strong upwardly directed leg II formed with an elongated opening 112.
  • the leg II and the lower grooved portion of the mounting means Ill form the metal mounting component of the yarn guide of the invention.
  • the leg 11 serves to fix the structure to the knitting machine, and it is for this purpose that'the elongated opening 12 is provided. By way of this opening 12 an accurate location of the yarn guide at the unillustrated mounting location is brought about.
  • the operating part of the yarn guide of the invention includes the ceramic one-piece body 13 which is received at an upper elongated portion thereof in the bottom groove of the mounting means 10. It is this ceramic yam-guiding member ll3 which is formed with the yam-guiding passage M which is illustrated.
  • this ceramic yam-guiding member ll3 which is formed with the yam-guiding passage M which is illustrated.
  • the yam-guiding member 13 is provided, as in the case with conventional yam-guiding members, at its front end with inclined surfaces 115 which facilitate opening or closing of partly open needle tongues.
  • the one-piece yam-guiding member 13 has its upper elongated portion received in the downwardly directed groove of the steel mounting member 10 in such a way that the connection between the components of the yarn guide of the invention will not permit them to be separated from each other except by longitudinal movement of the upper portion of the yam-guiding member 13 in the lower elongated groove of the mounting means 10.
  • any additional clamping or fixing means between the components 10 and 13 are not used, and in accordance with the invention it is only the mating configurations of the groove of mounting member l and the longitudinal portion of the yarnguiding member H3 received therein which serve to interconnect the components.
  • the configurations of the cross section of the groove of member 10 and the part of the member 13 received therein includes at side surfaces of these components a tongue-and-groove connection.
  • the right side surface of member 13 is formed with a groove which receives an inwardly directed tongue formed at the right side surface of the elongated groove which is formed at the lower end of the member 10, so that in this way a tongue-and-groove connection 16 is provided between components 10 and 13 preventing removal of member l3 from member 10 except by longitudinal movement along the groove of latter.
  • the member 13 can be received in the groove of the member 10 from the front end of the latter without any danger of the member 13 becoming separated from the member 10. At the same time, the member 13 can easily be exchanged for another member. In order to provide an even greater security in the connection between the components l0 and 13 these members may be glued to each other, if desired, as pointed out above.
  • the above-described structure of the invention has the advantage that in the passage 14 of the yarn-guiding member 13 there will be practically no wear resulting from the movement of yarn through the passage 1 3. Beside the extremely great hardness of the ceramic material, the surface thereof which defines the passage 14 has an outstanding low friction or slidability with respect to the yarn. Thus, with the yarn guide of the invention an extremely accurate yarn feed which will remain unchanged can be achieved, and the yarn will not in any way be damaged and does not have any fibers thereof removed by rubbing on the yarn guide during movement through the passage 14 thereof. Thus, the operating life of the yarn guide of the invention is practically unlimited.
  • the structure of the invention can achieve a universal utility.
  • the mounting means 10 By situating in the groove of the mounting member 10 the elongated upper portion of the guide 13 which has the corres onding cross section, the mounting means 10 provides latera stop surfaces for the yarnguiding member 13, and there is an assurance of an accurate guiding of the yarn and orientation of the components which guide the yarn.
  • a yarn guide device comprising a metallic mounting member having an elongated groove, a yarn-guiding member made of a single body of ceramic material, said yarn-guiding member formed with at least one guide passage through which yarn is guidingly fed to said circular knitting machine, said yam-guiding member having an elongated portion substantially matching the cross section of said groove and being longitudinally movable therein for adjusting the position of said yam-guiding member relative to said mounting member, and the configuration of the cross section of said elongated portion of said yarnguiding member and said groove preventing removal of said yam-guiding member from said metallic mounting member except by longitudinal displacement of said elongated portion of said yam-guiding member along said groove.
  • a yarn guide device as set forth in claim ll, wherein said metallic mounting member and said yam-guiding member are glued to each other along said elongated groove.
