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 which extends transversely from the side support engages in a pin-like manner with each corner connection and is clamped by means of a screw.
- the heald frames oscillating in a weaving machine are known to be subjected to a very high load due to the constant load change, and this is also becoming ever greater with the constantly improved weaving machines running with a higher number of revolutions, so that breaks on the side supports and caused by the high load in particular enter below the peg-shaped projection.
- the heald frames are now preferably made of light metal, but this material has the property that the flexural 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, on the other hand, is not the case with steel from reaching a certain limit value. In light metal, therefore, in view of the continuously decreasing curve mentioned above, the material breakage can occur at some point as a result of the higher stress.
- the heald frame has the features according to claim 1. With a vibration damping element in each corner connection between a side support and the shaft of the heald frame, the vibrations caused by the frequent load changes are counteracted and the force peaks are no longer transmitted hard from one part to another.
- 1 and 2 are side views of two different embodiments of a broken off side support with pre-tension
- FIG. 3 the side support according to FIG. 2 seen from the narrow side;
- FIG. 4 shows the corner connection of a heald frame, consisting of the side support in a further embodiment and the shaft rod shown broken off;
- a projection 2 is fastened on one narrow side, which is used to connect the side support to a shaft rod (not shown), which is referred to as a corner connection.
- a shaft rod (not shown), which is referred to as a corner connection.
- the projection 2 used for connection has a flat base part 2a which extends in the direction of the longitudinal direction of the side support 1 and 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 by Aufvul kani sieren with the side support 1 and with the projection 2 connected. 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 to 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 bevelled upper edge of the projection 2, which is shown only 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 vibration damping element 3 of greater overall length 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, they are interlocking and between the boundary surfaces of the side support 1 and the projection 2, a V-shaped groove is filled in the example according to FIG. 5 and a U-shaped groove is filled with the vibration damping element 3 in the example according to FIG. 6.
- 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 T is also used for guidance, 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.

Abstract
Pour avoir un raccord d'angle amovible sur une lame de métier à tisser, il est prévu d'utiliser une saillie (2) disposée sur le support latéral (1), laquelle est bloquée, au moyen d'une vis de serrage (6), dans la lamette (4) ayant un profil creux de la lame de métier à tisser. Entre le support latéral (1) et la saillie (2), il est prévu un élément amortisseur de vibrations (3) relié à cette saillie, de préférence par vulcanisation, constitué par un élastomère et présentant une forme de bande correspondant à la largeur du support (1). Le support latéral est ainsi raccordé à la lamette (4), pour chaque raccord d'angle, par l'intermédiaire de l'élément amortisseur (3), de sorte qu'on obtient un amortissement des vibrations qui se produisent, principalement aux régimes élevés de la machine, et qui pourraient entraîner des ruptures du matériau sur le support latéral.To have a removable angle connection on a loom blade, it is planned to use a projection (2) arranged on the side support (1), which is blocked by means of a tightening screw (6 ), in the lamette (4) having a hollow profile of the loom blade. Between the lateral support (1) and the projection (2), there is provided a vibration damping element (3) connected to this projection, preferably by vulcanization, formed by an elastomer and having a band shape corresponding to the width of the support (1). The lateral support is thus connected to the lamella (4), for each angle connection, by means of the damping element (3), so that one obtains a damping of the vibrations which occur, mainly at the speeds machine, and which could cause material breakage on the side support.
