Definitions

  • the invention relates to a leno device for weaving machines, with a stationary, frame-shaped leno thread guide and a central web forming one end fixed in the leno thread guide, forming two leno thread alleys, the other, free end of which forms a passage for the leno thread from one to the other alley, further with one in Area of the passage in the leno thread guide element which guides the leno thread from the one lane to the other lane in a loom-alternating manner, while at the same time crossing the vertical thread which is guided by a liner thread needle which is moved asynchronously between the two lanes.
  • the proposed leno device (EU application 84105316.8 from the applicant) has the disadvantage that it takes up a relatively wide space with regard to the warp thread displacement width. Furthermore, the guide element designed as a switch or spoke wheel for the leno thread tends to become stiff due to contamination.
  • the invention has for its object to provide a lathe device of the type defined, which takes up a less wide space and wherein the deflection member is not difficult.
  • This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous further developments.
  • a leno device 1 consists of a frame-shaped leno thread guide 2 fixed to a weaving machine (not shown) and a standing thread needle 4 fastened to a heald frame 3.
  • the standing thread needle 4 has a thread guide 5 at the upper end and a thread eyelet 6 at the lower end
  • a standing thread 7 runs from a supply spool through the thread guide 5 and the thread eyelet 6 to a shed tip 8 of a fabric 9.
  • the leno thread guide 2 has two lanes 13 and 14 on both sides of a central web 12, which are connected to one another by a passage 15.
  • the standing thread needle 4 is located in the middle between the two alleys 13 and 14.
  • a leno thread 16 comes from the warp beam through a strand 17 of the heald frame lying behind the front heald frame 3 and from there alternately through the alleys 13 and 14 to the shed tip 8 as will be explained later.
  • the leno thread 16 In the drawn high position of the strand 17, the leno thread 16 is in the left lane 13 of the leno thread driver; in the down position, it is located in passage 15 and is designated 16 'there.
  • the standing thread needle can be attached to another drive element, for example a jacquard machine, instead of on a heald frame.
  • the leno thread guide 2 is provided with a guide element 20 for the leno thread, which can be seen more clearly in FIG. 2a.
  • the guide element 20, which is U-shaped, has an opening 21 between two legs 22 and 23.
  • the guide element 20 rests with its yoke 20 'on an inclined floor 24 of the passage 15 and with one side 25 of the leg 23 against an inside 26 of the alley 14.
  • An inside 27 of the leg 22 rests against a tapered part 12' of the central web 12.
  • In this position of the guide element 20 there is a passage 29 between an inside 30 of the alley 13 and the leg 22 and a passage 31 between the tapered part 12 'of the central web and an inside 33 of the leg 23.
  • Both legs 22 and 23 are located in an enlarged part 13 'or 14' of the alley 13 or 14. This prevents the leno thread from getting into the wrong passage during its movements, as will become apparent. A possible guidance of the guide element 20 in the leno thread guide 2 will be described with reference to FIG. 5.
  • the lathe device works as follows:
  • the leno thread 16 Before the start of the leno movement, the leno thread 16 is in the upright position in the left lane 13.
  • the standing thread needle 4 with the upright thread 7 is in the down position and is designated in this position by 7 '.
  • the guide element 20 rests on the floor 24 of the passage 15. FIGS. 1 and 2a.
  • the leno thread 16 When the leno thread 16 is moved downward through the strand 17 in the alley 13 during the downward movement, it passes the guide element 20 in the passage 29 and slides to the right over the inclined floor 24. It is labeled 16 'there.
  • the leno thread 16 and the upright thread 7 thus cross each other.
  • the leno thread 16 crosses over an inserted weft thread 35.
  • the weft thread is thus integrated.
  • the next weft thread 36 is now entered.
  • the leno thread 16 ' is raised; it crosses over the weft thread 36.
  • the leno thread 16 ' displaces the guide element 20 to the left and creates a passage 37 between its leg 23 and the inside 26 of the leno thread guide (FIG. 2b) and from there reaches the right-hand lane 14
  • the upright thread 7 was simultaneously moved downwards and into position 7 '; it crosses over the weft thread 36.
  • the guide element 20 slides back into the position shown in FIG. 2c.
  • the next change of subject follows.
  • the leno thread 16 'in the alley 14 is moved downwards, the upright thread 7' is moved upwards.
  • the leno thread 16 'slides through the passage 31 between the central web 12 and the right leg 23 and reaches the opening 21 of the guide element.
  • Fig. 2c During the next change of subject, with the leno thread 16 being moved upward, it displaces the guide element 20 to the left and creates a passage 42 between the tapered part 12 'of the central web 12 and the left leg 22 of the guide element.
  • Fig. 2d During the upward movement of the leno thread 16 in the alley 13, the upright thread 7 is moved downward. This completes a spin cycle.
  • the leno device I consists of a leno thread guide 51 with a guide element 52 and a standing thread needle 53.
  • the guide element 52 is U-shaped and has two legs 54 and 55 which surround a central web 56.
  • the guide element 52 is guided by means of a groove in the leno thread guide.
  • the outside of the leg 54 has a groove 58, the upstanding edges 59 and 60 of which engage around the base plate 50 with sufficient play to allow a leno thread 61 to pass through.
  • the leno thread guide 62 of the leno device II is designed in the same way.
  • Each of the leno devices I and II works in the same way as described for the leno device according to FIGS. 1 and 2a to 2c, but antisynchronously. In this way, two leno edges 63 and 64 are formed with an intermediate cutting edge 65, where the tissue is subsequently cut. Fig. 6. Such a doubling is also used in particular when weaving with very smooth yarns, for example. The number of devices depends on the respective requirements.
  • a leno thread guide 70 has a U-shaped guide element 71 in the form of a wire structure made of spring wire.
  • the guide element 71 lies on four points 72, 73, 74 and 75, but is otherwise freely movable.
  • the support points 72 and 74 are on the sides of the leno thread guide, the support points 73 and 75 on a central web 76.
  • Each support point, for example 74, is formed by a groove 77 in a trough 78. When passing through a turner the latter deflects the guide element 71 into the shape 80 shown in broken lines, so that a passage for the leno thread is created.
  • FIG. 9 there is a U-shaped guide element 81 of a leno thread guide made of spring tape, which is provided on both sides with a thickened edge 82 and 83, respectively. Both edges encompass the thickness of the leno thread guide.
  • a leno thread passing the guide element 81 is designated 85.
  • a guide element 91 is formed from a leaf spring similar to that in FIG. 7, but it rests on pins 92, 93, 94 and 95 which are fastened on both sides of the leno thread guide. With each pin, the guide element is provided with a recess for receiving the leno thread guide. 10 that the guide piece 91 above the pins 94 and 95 has a recess 96 and 97, respectively, which receive the leno thread guide.
  • the delimiting strips 98 and 99 encompass the leno thread guide. The operation of the device is as described for the previous exemplary embodiments.
  • the guide element can have a V-shaped shape.
  • the lathe device is described here for a weaving machine with heald frames, it can of course also be used for a weaving machine with a jacquard machine.
