Definitions

  • the invention relates to a heddle, which is adapted for processing warp threads, which are formed in the manner of ribbons.
  • looms which have at least one, but usually many so-called heald shanks for shedding.
  • Each weave is formed by a substantially rectangular frame made vertically arranged side supports and an upper and a lower spar, the so-called shaft rod exists.
  • Litzentragschienen are held on the shaft rods, which are usually formed by elongated steel rails with a rectangular cross-section. The steel rails are used to hold healds.
  • Each heald has end loops for threading onto the top and bottom steel rails. Between the end eyelets of the heddle body extends. Approximately in the middle a thread eye is provided, through which the warp thread leads. If the shaft rod is moved upwards or downwards, all warp threads leading through the thread eyes of the strands are guided out of the warp thread bundle upwards or downwards, so that a shed is formed.
  • the FR 394 156 discloses such a heddle made of flat strip steel.
  • the flat sides of the steel strip are oriented in warp direction.
  • the heald is compressed and punched in the area of the same.
  • the resulting thread eye has a height measured in the vertical direction which is greater than the width measured in the horizontal direction.
  • the thread eye is oriented in warp direction.
  • the DE-PS 22996 discloses a heddle with warp-oriented yarn eye.
  • the heald consists of two layers of thin metal strips that lie parallel to each other. In the area of the thread eye the metal strips are arched away from each other.
  • the heddle is wound around its longitudinal direction, so that the thread eye is oriented transversely to the end eyelets.
  • the presented healds are suitable for processing substantially round threads.
  • ribbon-shaped fiber arrangements for example, polyester, aramid or carbon fiber band-shaped thread arrangements are to be processed, e.g. for producing fabrics for reinforcing highly stressed composite structures.
  • the demand arises that the band-shaped fiber bundle retains its band-shaped structure in the weaving process, and e.g. aligned parallel to the tissue plane.
  • a heald for flat tape-shaped warp threads known, which consists of a flat material. In the region of its thread eye, it has a parallelogram-shaped limited area, which is provided with a transverse slot. The transverse slot forms the thread eye.
  • the US-B-6283163 and the GB-A-408188 disclose wire bent strands which are provided to form a thread eye with an annular grooved member.
  • the heddle according to the invention on a strand body with a thread eye, seen in the warp direction is wider than high.
  • the shape of the thread eye is insofar approximated to the shape of the band-shaped or ribbon-like warp thread or a corresponding warp thread group, which is considered here as a warp thread.
  • the width of the thread eye is at least a few tenths of a millimeter larger than the width of the ribbon-like warp thread for which the heald in question is provided.
  • the thread eye is provided at its upper and at its lower edge with a Fadenleit simulation, the yarn inlet side and / or yarn outlet side is rounded, wherein extending in the warp direction length of this yarn guide is greater than the thickness of the strand body to be measured in the same direction.
  • the heddle body can be made relatively thin and, for example, consist of sufficiently strong steel. The risk that form sharp edges on the thread eye, which can damage sensitive threads is banned by the inventively provided Fadenleitfiguration. The thickness of the heald can thus be reduced to a minimum, which reduces the weight of the strands and thus the material costs and on the other hand increases the possible achievable working speed.
  • the heald is rotated at least in the region of the thread eye transversely to the warp thread, i. the flat sides of the heald lie in a plane which also contains the two heddle rails or encloses with them an at least very acute angle near 0 °.
  • This ensures that the opening direction of the thread eye substantially coincides with the running direction of the warp thread.
  • the minimum thread eye width is made possible for the required opening width of the thread eye.
  • a first heald is moved down to the lower position and a second heald up to the upper position. Both heddles have healds according to the invention, through the thread eye of which warp threads run. After the movement of the first heald to the lower position and the second heald to the upper position, for example, each forms a warp thread of the first heald with a warp thread of the second heald a so-called shed.
  • the warp thread of the first heald passes through a thread eye of a strand in the first heald in the lower region, wherein the warp thread of the second heald passes through a thread eye a strand of the second heald in the upper region. This is how a shed is formed.
  • the two healds change their position.
  • the first weaving shaft goes up, at the same time the second weaving shaft goes down.
  • the heddles also change the positions of the heddles and thus the warp threads or warp thread bundles passing through the thread eyes of the heddles.
  • this position change of the warp threads of the warp thread of the second heald sweeps the outer edge of the adjacent heald passing the first hive.
  • the warp thread passing through the thread eye of the first heald passes the outer edge of the adjacent heald of the second heald.
  • the thread eye of a strand according to the invention is rotated transversely to the warp thread, the area between the outer edge of the strand and the thread eye can be made very small.
  • This provides a warp thread of an adjacent strand of an adjacent heald shaft when changing position enough space to pass freely past the edge of the heald of the adjacent heald shaft.
  • the risk of injury to warp threads when changing position is greatly reduced.
  • the formation of close-meshed tissues is possible.
  • the formation of close-meshed fabrics a slight inclination of the strand body in the region of the thread eye serve, whereby the opening direction of the thread eye is inclined at an acute angle of a few degrees against the plane mentioned in claim 3.
  • the heddle body consists of a band-shaped material, e.g. a steel band. At least on his thread eye he can be oriented transversely to the warp. The twist between the thread eye and the end eyelets is preferably 90 °.
  • the Enderia can be formed by a separate, connected to the heald body element.
  • it is an integral part of the Litzen stresses, ie it consists of the same material as this and goes seamlessly and seamlessly into this.
  • the heald can thereby be produced as a simple stamped body.
  • the end eyelet may have any known shape such as the so-called O-shape, C-shape or J-shape or any future developed form.
  • the end eyelets are formed by projections which are attached to the heald body and protrude over the flat side.
  • the projections may be formed for example by tongues, which are cut free from the heddle body and bent out laterally.
  • the projections may also be formed by subsequently attached to the flat side of the strand body elements.
  • Such elements may be, for example, by laser welding or riveted metal tabs, wherein the weld can be made longitudinally or transversely to the longitudinal direction of the heddle body.
  • the version with longitudinally oriented weld leads to a particularly high stability of the end eyelet thus formed.
  • Fadenleit vom which may be formed for example by tabs that are bent out of the thread eye.
  • the released tabs are bent out of the thread eye by at least 110 °. This results in generously dimensioned yarn guide surfaces, which can be used to weave brittle, break-sensitive threads.
  • the thread guide surfaces on separate elements which are connected to the strand body are connected. They thus form the upper and / or the lower edge of the thread eye.
  • the separate elements may be made of hardened steel, carbide, plastic or ceramic.
  • the elements can be connected to the strand body by gluing, soldering or welding.
  • cemented carbide or ceramic allows interweaving particularly aggressive tapes, such as aramid fibers.
  • the additional elements may also be provided with portions which protect at least a portion of the lateral flanks of the thread eye. This is achieved, for example, by having the elements in the form of a pin or disk end pin.
  • the elements clearly project beyond the upper and lower edges of the thread eye.
  • the elements are in the form of smaller, arranged on the flat sides of the strand body platelets whose edges are well rounded. These plates are attached to the front and back flat side of the strand body and lay according to their positioning, the height of the thread eye in the longitudinal direction of the strand. With this measure, thread eyes of different height can be realized on uniformly punched strand bodies, so that the respective strands can be set up for different band-shaped warp threads.
