Definitions

  • the invention relates to a heddle with at least one frame part and with at least one Litzentrag ⁇ rod attached to the frame part.
  • the heald frames should be as light as possible in order to enable high weaving speeds while, on the other hand, they should be as dimensionally stable and rigid as possible.
  • the frame parts are therefore made of a lightweight material, preferably as hollow profiles, in order to achieve the greatest possible flexural rigidity.
  • the heddle rods, which are adapted to the shape of the strands and which are exposed to wear due to movements of the strands, on the other hand are made of a hard as possible ver ⁇ wear-resistant material, in particular steel.
  • the frame parts are extruded aluminum alloy profiles.
  • the upper frame part is provided with a downwardly projecting flange and the lower frame part with an upstanding flange.
  • the bil ⁇ a receiving groove for the central web of a T-shaped heald rod between the bil ⁇ .
  • the center bar of the heald bar is glued into the groove.
  • the webs of the flange of the frame part are provided with projections. The frame members and the shaft support rods are placed in a press and held so that they can not move relative to each other when the adhesive is thermally cured at about 120 0 C.
  • the invention has for its object to provide a weaving shank of ein ⁇ initially mentioned type, in which a simple and secure connection between the frame part and the litz support rod is provided, the like without pressing or teaching or the like. can be produced.
  • the frame part is provided with a profile rib running in the longitudinal direction, and that the Lit ⁇ zentragstangen has a profiled longitudinal groove which engages around the profile rib.
  • the tread rib can easily be dimensioned so strong that the risk of damage is relatively low.
  • the material of the heald bar has a relatively higher strength, so that the longitudinal groove mounted in the heald bar does not pose a great risk of damage.
  • the profile rib of the frame part and the profiled longitudinal groove of the Litzentrag ⁇ rods form a positive connection transversely to the longitudinal direction.
  • a positive connection leads to the frame part and the heddle rod exactly aligned with each other during assembly be without a press or a teaching or stencil or the like. necessary is.
  • the profile rib of the frame part forms a latching connection with the profiled longitudinal groove of the heddle carrier rod. Such a locking connection allows a particularly simple installation.
  • the profile rib of the frame part is glued to the longitudinal groove of the heddle carrying rod.
  • the adhesive for example, a thermosetting adhesive, increases the safety of the connection between the frame part and Litzen ⁇ support rod.
  • the adhesive compensates for play between the profile rib and the longitudinal groove, but without determining the position of the two, which is determined by the positive connection.
  • FIG. 5 shows a section through the heddle rods according to FIG. 4, after having been given its final shape
  • FIG. 6 is a partial section similar to FIG. 2 on a larger scale
  • 7 shows a partial section similar to FIG. 6 with an additional damping profile

From the upper frame part 10 projects downwards from a flange 23, which is provided with a Profilrip ⁇ PE 24. On this Profilhppe 24 is a heddle rod 17th attached, which is a flat bar, which is provided with a profiled longitudinal groove which engages around the rib 24.

  • the heddle rod 17 is an extruded steel profile which is first extruded in the mold as shown in FIG. At first, it has a longitudinal groove 25 'which is rectangular in cross-section and whose side flanks are extended by means of longitudinal ribs 27, 28 protruding beyond the contour of the strip which is in itself flat. These longitudinal ribs 27, 28 are then plastically deformed by cold rolling so that they lie within the outer contour, so that a straight, smooth outer side results. The longitudinal ribs 27, 28 are pressed into the previously rectangular longitudinal groove 25 'so that the dovetail-shaped undercut longitudinal groove 25 results, as shown in FIG. 5. As can be seen from FIGS. 4 and 5, the longitudinal rib 28 is slightly smaller in cross section than the longitudinal rib 27.

Even if this adhesive should lose its adhesive effect over time, so keeps he is the function of balancing game as long as it still exists. Losing the adhesive effect over time may be advantageous for disassembling the heddle rod 17. It is therefore possible deliberately to use an adhesive which loses its adhesive effect after a predetermined time.
