Definitions

  • the invention relates to a heald for a heald with the features of the preamble of claim 1.
  • the heddles In shedding, the heddles each move the warp threads passing through their thread eye out of the warp thread plane, with other warp threads passing between the strands being moved in the same or opposite direction by means of another weaving shank.
  • the tensioned warp threads run along the outside of a heald during each shedding process. This is an extreme burden on the threads, which can lead to Kettfadendamäd Trent and in extreme cases to Kettfadenbruch.
  • the heald consists of a suitably shaped flat material. In the area of the thread eye, it is so twisted that the flat sides are at an angle to the warp direction. The existing between the heddles warp threads that do not run through the thread eye must paint over the outer edges of the thread eye in the shedding and can be damaged.
  • the same document discloses a heddle which is not twisted in the region of its thread eye, but in which the two webs delimiting the thread eye are merely set.
  • both side surfaces of the heddle are oriented over their respective entire length substantially in the warp direction.
  • a sharp corner is formed, which may tend to cut a warp thread.
  • the laterally bent legs do not prevent adjacent healds come so close to each other that a leg of an adjacent heald overlaps the thread eye of a considered heald. This can also cause warp threads to run up and down the more or less sharp edges of the heald and thus be damaged.
  • the EP 0403429 discloses a heald of fiber reinforced plastic.
  • the heddle body is provided with rounded edges both in the area of the thread eye and in the sections extending away therefrom.
  • adjacent thread eyes may overlap one another. Between the healds running threads that must pass through the thread eyes in the shedding, can be damaged. This is especially true at high speeds.
  • the heddle according to the invention has a strand body, which is provided on the thread eye with a spacer means. This prevents adjacent healds from overlapping each other in the area of the thread eyes viewed in the warp direction. As a result, a thread running between the heddles, when it passes the thread eyes of the adjacent healds, is not pushed out of the warp thread direction, or only marginally. In particular, it is not urged on edges of the heald or thread eye, where it could be damaged. In particular, the processing of thermally sensitive threads, not only by sharp edges, but also could be damaged by frictional heat, so is possible with high operating speeds. By avoiding strand overlap, especially in the area of the thread eyes, a low-deflection and thus low-friction yarn path for the warp threads becomes possible both with regard to their slow longitudinal movement (in warp direction) and with regard to their shedding motion.
  • the side surface is oriented over its entire, with respect to the shedding effective length, preferably in the warp direction. This applies in particular to the areas adjacent to the thread eye and the thread eye itself. This prevents yarn damage to the thread running past the heddle straight at the constriction formed by the thread eye.
  • the side surface is preferably a flat surface on the thread eye.
  • the webs limiting the thread eye need not be bulged laterally - they may rather be formed substantially straight. This creates the possibility to set the inner contour of the thread eye so that no upper and lower sharp corner occurs in which the warp could wedged and damage. In addition, it is prevented that the running past the thread eye passing thread remains hanging on the thread eye.
  • the spacer means is preferably formed by a portion of the side surface which adjoins the thread eye.
  • a surface area can be found, for example, in the vertical longitudinal direction of the heald directly above or below the thread eye.
  • the heddle body has a thickness which is as great as the distance of the side faces of the webs in the region of the thread eye.
  • the side surfaces are preferably inclined in the direction away from the thread eye to the longitudinal direction and thus formed as a ramp surface.
  • the side surfaces are formed as ramp surfaces to guide the thread eye crossing yarn safely.
  • the ramp surfaces are preferably formed as flat surfaces. However, they can also have a slight curvature.
  • the distance of the two opposite side surfaces in the region of the thread eye ie the thickness of the strand body above and below the thread eye is greater than the measured width in the same direction of the thread eye. This helps to maintain the desired thread eye distance.
  • the predetermined by the thread eyes running through the warp threads pitch ie the center distance of adjacent thread eyes, can not be less than even with closest possible contraction of adjacent healds the outer width of the thread eyes and certainly not less than the inner width thereof.
  • the thread eye is preferably bounded by webs whose inner sides form guide surfaces which are parallel to the side surfaces. This leads to a gentle threadline through the thread eye. Furthermore, the thread eye is bounded both above and below preferably by flat or slightly curved surfaces which extend in the warp direction and are substantially smooth, which also serves a gentle threadline. These surfaces are curved on the yarn inlet side of the heald and, if necessary, on the yarn outlet side of the thread eye away. This causes a thread conservation, especially when the tray is open.
  • the thread eye limiting webs are offset with respect to the Kettfadenraum against each other, so that a Kett therapiessabstand is present.
  • the webs are offset transversely to each other, whereby a transverse distance is formed.
  • the Kettidessabstand is preferably greater than the transverse distance.
  • the side surface may be provided with a recess, for example a groove extending in the longitudinal direction L of the heald. This significantly reduces the mass of the heald without adversely affecting its strength.
  • the stranded body can be made of plastic, which results in weight advantages Has. In addition, it may consist of a fiber-reinforced material, for example aluminum with boron fibers, and thus be both light and strong. It is possible to seamlessly form the heddle body from one and the same material, ie in one piece. This avoids weak spots and enables easy production.
  • the heald body can be wholly or partially, for example, in particular in the region of its thread eye, provided on the inside as well as on its side surfaces with a wear-reducing coating. In particular, the sawing of a thread into the thread eye can thereby be avoided.
  • the thread eye may also be replaced by a wear resistant insert, e.g. be formed of ceramic, a hard metal or a hard metal, said use may, if necessary, still be coated. As a result, light and very wear-resistant strands are obtained.
  • a wear resistant insert e.g. be formed of ceramic, a hard metal or a hard metal
  • FIG. 1 some components of a loom 1 are illustrated, belong to the healds 3 with healds 4.
  • the healds 3 are substantially flat, rectangular frames in which the heddles 4 are held vertically.
  • the heddles 4 are used to guide warp threads 5, some of which are guided through corresponding thread eyes 6 of the heddles and others between the healds.
  • the healds are there, as well FIG. 2 can be seen, held substantially parallel next to each other tightly sealed.
  • the healds 3 are moved in operation of the loom 1 in rapid succession and down, including an in FIG. 1 only to the utmost schematized illustrated shaft drive 7 is used.
  • the healds of a shaft 3 are preferably formed equal to each other. You have, for example, a form according to FIG.
  • Each heald 4 has an approximately strip-shaped elongated strand body 8 oriented vertically in use, which is provided with the thread eye 6 in a central region.
  • C-shaped end eyes 9, 10 adjoin the strand body 8.
  • run-holes 11, 12, partial slots 13, 14 and cut-off edges 15, 16, 17, 18 are formed.
  • the heald 4 is correct FIG. 3 with the healds 4 after the FIGS. 4 and 5 essentially coincide. Differences exist insofar as the healds 4 according to FIG. 4 closed end eyelets 9, 10 and the healds 4 according to FIG. 5 J-shaped end eyelets 9, 10, but with inwardly angled hook 19, 20 have. Deviations also exist in the alignment between the strand body 8 and the end eyelets 9, 10. While the end eyelets 9, 10 according to FIG. 3 are arranged in a straight extension of the strand body 8 is in the healds 4, according to the FIGS. 4 and 5 , an offset exists, so that it becomes possible to mount adjacent healds 4a, 4b with an offset with respect to the warp direction K. This results in two rows of thread eyes, which is also called double thread suction. Furthermore, it is possible to provide each heald 4 only on one side with separation edges 15, 17 and 16, 18.
  • the heddle body 8 in the embodiments described above is preferably wholly or partially made of a plastic, such as a fiber-reinforced plastic.
  • a plastic such as a fiber-reinforced plastic.

  • a suitable metal for example magnesium, aluminum or a magnesium or aluminum alloy.
  • for the processing of aggressive warp yarns can be provided to provide the healds 4 with a wear-resistant coating. This applies in particular the area of the thread eye 6, as well as the side surfaces of the strand body.
  • this is preferably an anodized layer.
  • the end eyelet 9, 10 may be an integral part of the heald 4. This means that the end eyelet 9, 10 seamlessly connects to the heald body 8 and is formed of the same material as this. However, it is alternatively also possible to attach the end eyelets 9, 10 to the heald body 8 and if necessary to produce them from a different material.

Following the section II, in the direction of the end eyes 9, 10, the side surfaces 23, 24 preferably run parallel to one another, so that the thickness of the strand body 8 remains constant. In the illustrated transition region between the thread eye 6 and the thinner part of the strand body 8, slot-like or groove-like recesses 29, 30, 31, 32 may be provided, in particular from FIG. 9 can be seen.
