Definitions

  • the invention relates to a heald frame with releasable corner connections between the side supports and the shaft rods consisting of hollow profiles, in the cavity of which a projection extending transversely from the side support engages in a pin-like manner with each corner connection and is clamped by means of a screw (see for example US-A-4 741 367).
  • the heald frames that oscillate in a weaving machine are known to be subjected to a very high load due to the constant load changes, and this is also becoming ever larger with the continuously improved weaving machines running at a higher number of revolutions, so that breakages caused by the high load on the side supports and in particular below the pin-shaped one Get ahead.
  • the heald frames are now preferably made of light metal, but this material has the property that the alternating bending strength of this material, plotted as a curve over the number of load changes, initially decreases steeper up to a certain value and then weaker but steadily further, which in contrast Steel is not the case from reaching a certain limit.
  • the material breakage due to the higher stress can occur at some point in view of the continuously decreasing curve mentioned above.
  • the heald frame has the features according to claim 1.
  • a projection 2 is fastened on one narrow side, which serves to connect the side support to a shaft rod, not shown, which is referred to as a corner connection.
  • the projection 2 serving to connect has a flat base part 2a extending in the direction of the longitudinal direction of the side support 1, which only has the purpose of increasing the area with which it bears against the vibration damping element 3 shown in cross-hatching. This is preferably connected by vulcanization to the side support 1 and to the projection 2. The larger this vibration damping element, the more the effect to be achieved is also better.
  • Fig. 4 shows the connection of a side support 1 with the shaft rod 4 of a heald frame, in the cavity 5 of which the projection 2 engages on the side support.
  • the connection is made by clamping by means of a clamping screw 6 pressed obliquely through the shaft rod 4 and against the chamfered upper edge of the projection 2, which is only shown with the center line.
  • the vibration damping element 3 is no longer than the projection 2 engaging in the cavity of the shaft rod 4.
  • a the overall length of the greater vibration damping element 3 is located between the side support 1 and the projection 2, which no longer lie against the vibration damping element with plane-parallel surfaces as in the previous examples.
  • the side support 1 and the projection 2 are in the examples according to FIGS. 5 and 6 in other words interlocking and between the boundary surfaces of the side support 1 and the projection 2 in the example according to FIG. 5 a V-shaped groove and in the example according to FIG. 6 a U-shaped groove is filled with the vibration damping element 3.
  • FIG. 7 and 8 show views from above of a side support 1 and the projection 2 connected to it, which is narrower than the side support in order to be able to be inserted into the cavity 5 of the shaft rod 4.
  • the vibration damping element 3 between them is the same width as the side support, which can have different profile shapes.
  • the side support 1 also serves as a guide, a U-shaped profile shape according to FIG. 7 including a guide rail or an L-shaped profile shape according to FIG. 8 being received on one side by a guide groove.
