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.

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.

Claims (5)

  1. Cadre de tissage comportant des jonctions angulaires amovibles entre les montants latéraux et les liteaux qui sont constitués de profilés creux et dans l'espace creux desquelles, pour chaque jonction angulaire, une saillie s'étendant transversalement à partir du montant latéral pénètre à la manière d'une goupille et est bloquée au moyen d'une vis, caractérisé en ce qu'entre le montant latéral (1) et la saillie (2, 2a) qui sert au blocage il est agencé un élément d'amortissement d'oscillation (3) qui est raccordé de façon adhérente aux deux éléments et qui agit sans être influencé par le couple de serrage de la vis de blocage (6).
  2. Cadre de tissage suivant la revendication 1, caractérisée en ce que l'élément d'amortissement d'oscillation (3) est une bande de matière qui est constituée d'un élastomère comme du caoutchouc, une matière en genre de caoutchouc ou du polyuréthanne et qui présente une section transversale sensiblement constante.
  3. Cadre de tissage suivant la revendication 1, caractérisée en ce que l'élément d'amortissement d'oscillation (3) est raccordé de façon adhérente par vulcanisation ou collage au montant latéral (1) et à la saillie (2, 2a).
  4. Cadre de tissage suivant la revendication 1, caractérisée en ce que la saillie (2, 2a) présente une partie de base (2a) plate, qui s'étend dans une direction parallèle au montant latéral au-delà de la partie pénétrant à la manière d'une goupille dans l'espace creux (5) du liteau (4), pour le raccordement par adhérence avec un élément d'amortissement d'oscillation (3) en forme de bande, plus long de façon correspondante et s'étendant sur toute la surface de la partie de base.
  5. Cadre de tissage suivant la revendication 1, caractérisée en ce que le montant latéral (1) et la saillie (2), séparée de ce support par l'élément d'amortissement d'oscillation (3) en forme de bande, sont réalisés de façon interpénétrante avec un contour de même forme de leurs surfaces d'adhérence raccordées à l'élément d'amortissement d'oscillation, et délimitent par exemple un canal en forme de V ou en forme de U rempli avec l'élément d'amortissement d'oscillation (3) en forme de bande.
