Definitions

  • the invention relates to a device for forming a leno binding according to the preamble of claim 1.
  • a device for forming a Leno binding known.
  • This device includes one Standing needle bar, which is intended to hold the standing threads, three additional shaft frames to hold the leno threads.
  • a first framework contains a longitudinal rail with small, sloping slots for Picking up the leno threads.
  • a second frame contains a longitudinal rail with a groove for guidance that extends over the entire width of the weave all leno threads.
  • the third frame has a swivel arrangement around to tighten the leno threads so that the leno threads are in the Move the diagonal slits of the first frame in the direction of the weaving width.
  • a disadvantage of this known arrangement is the fact that the Device is relatively expensive.
  • the object of the present invention is an economically more advantageous one To propose a device for forming a leno binding.
  • the object is achieved in particular with a device for forming a Includes leno binding from a leno thread and a stand thread a reed for guiding the leno thread and the standing thread, one Needle bar with stand-up needles for guiding the stand-up thread and one movably mounted leno thread displacement device, the needle bar and the leno thread shifting device is arranged in front of the reed, wherein the leno thread shifting device comprises a laying element, which in a substantially parallel to the direction of the reed extending displacement direction is slidably mounted, and wherein the Laying element has guide means for guiding the leno thread, and the leno thread shifting device in a transverse to the Direction of movement of the reed running direction, in particular in a substantially vertical direction, is movably supported, around the leno thread both in the direction of displacement and in Moving direction.
  • the device according to the invention thus has a Leno thread shifting device, which the leno threads both in Direction of movement, which is preferably essentially vertical, as well as in the direction of the weaving width or in the direction of the reed, to controllably move the leno threads and in particular into the Spaces of the needle bar formed by the standing needles immerse and remove again.
  • the device according to the invention allows the leno thread to be moved extremely precisely and is also relative Low mass and thus allows a quick and flawless weaving of a Leno fabric.
  • the device according to the invention is inexpensive producible.
  • both Leno thread shifting device as well as the standing needle bar slidably mounted, which has the advantage that the through thread and leno thread trained shed even faster or with one lower stroke movement can be generated. This measure is a another increase in web speed possible.
  • the entire weaving width Upright needles for upright threads or laying elements with guide means for Leno threads are arranged to create a fabric overlying it entire width only has a leno binding.
  • the device can also be used to produce a fabric that has one or more Sections of the fabric width has a leno weave, whereas the Warp threads of the other sections have a different weave.
  • the device according to the invention can be used in combination with weaving machines different types are operated, for example with Air weaving machines, with rapier weaving machines or with Projectile looms.
  • Figure 1 shows the device 1 for forming a leno binding, which in Essentially the standing needle bar 4 and the Includes leno thread shifting device 5.
  • the standing needle bar 4 has in Stand needles 4a spaced apart in the direction of the weaving width Stand-up needle loops 4b.
  • the standing needle bar 4 shown Deflection element 4d for upright threads 3.
  • the upright threads 3 are over a deflecting boom 10 and the deflecting element 4d and deflected by the Standing needle eye 4b extending and between the slats 6a of the reed continuously fed to the fabric 7.
  • the standing needle bar 4 can be fixed be arranged or movably mounted in the direction of movement 4c.
  • the leno thread shifting device 5 can be shifted in the vertical direction 5f stored and comprises a laying element 5a with guide means 5p for guiding of the leno thread 2.
  • the laying element 5a is in a direction of displacement 5b, which in the direction of the weaving width or in the direction of the reed 6th runs slidably.
  • the Leno thread shifting device 5 a second in the direction of the Leno thread 2 spaced laying element 5c and two vertical guides 5d, 5e, which form a gap between which the leno thread 2 runs.
  • Through each standing needle eye 4b or through each Guide means 5p can each have one or a plurality of leno threads or upright threads 2, 3 can be arranged to extend.
  • the upright threads 2 and Leno threads 3 can also be arranged such that in each eyelet 4b or only a single thread runs in each guide means 5p.
  • the stationary needle bar 4 is the position of the standing thread 3 given, the position of the leno thread 2 by the movement of the Leno thread shifting device 5 in the vertical direction 5f cyclically into one Leno thread in 2H high position and one leno thread in low position 2T is moved.
  • the movement of the leno thread shifting device 5 is coordinated such that the movement in the direction of displacement 5f and the movement 5b in the direction of the reed 6 of the leno thread 2 alternating between two different ones, through the standing needles 4a trained spaces is inserted in which the combined Movement 5g is performed.
  • Figure 2 shows a side view of the device 1 for forming a Leno edge.
  • the leno thread shifting device 5 is initially in a lower position 5T, so that the leno thread 2T is held in lower position.
  • the standing needle bar 4 is fixed in the first embodiment arranged and holds the upright thread 3H in the high position, so that between a leno thread is formed for the leno thread 2T and the upright thread 3H, into which a projectile guided with a projectile guiding device 12a 12 is insertable, which enters a weft thread 13. Then it will Advised 6 with slats 6a in the direction of movement 6d to the fabric edge struck so that the reed is in the attachment point 6c.
  • the reed 6 becomes 6d again in the direction of movement continuously returned to the open position 6b.
  • the leno thread shifting device 5 While striking of the reed 6 and the subsequent movement into the open position 6b the leno thread shifting device 5 by a reversing movement in which the leno thread displacement device 5 in the direction of movement 5f is lifted vertically and raised to 5H, the Laying element 5a is also displaced in the direction of displacement 5b, and then the leno thread shifting device 5 again in the vertical direction 5f is moved to the subscript 5T, so that it is initially in the Lowering 2T located leno thread 2 is raised to the high position 2H, and then into a different space between two Standing needles 4a is brought back to a lower position 2T.
  • an open thread Shed from which a weft thread 13 can be inserted.
  • the standing needle bar 4 is as in FIG. 2 shown in dashed lines, also movably mounted in the direction of movement 4c. After the weft thread has been inserted, the standing needle bar 4 from the upper position to the lower position shown in broken lines transferred. And the leno thread shifting device 5 becomes more vertical Direction 5f raised until the leno thread 2T is higher in the vertical direction when the standing needle 4a comes to rest, as shown by the dashed line leno thread 2HH shown.
  • the leno thread shifting device 5 in in this case, only cover about half of the vertical path, so that the displaceably mounted standing needle bar 4 has the advantage that a new shed with less movement of the Leno thread shifting device 5 can be generated, for example a faster weaving allowed.
  • Figure 4 shows a shaft frame 11, which is of a fixed arrangement Bracket 5k with vertical side guide 5h in the vertical direction 5f is slidably mounted.
  • the leno thread shifting device 5 is at the top hung on a bracket 5l on the frame 11, and below via springs 5m connected to the frame 11.
