Definitions

  • the present invention relates to a damping system intended to be associated with a weaving machine mechanism of the kind comprising, for the selective control of a wire or a group of wires, at least one member which is positively animated by a desmodromic oscillating movement.
  • a mechanism for controlling the reciprocating movement of a group of wires in a weaving machine is known, for example documents EP-A-0 133 966 and CH-A-558 435.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and allow the general amortization of inertial forces of the moving masses of a machine mechanism weave.
  • each oscillating member is associated with elastic means which act in an antagonistic manner on said organ so as to tend to return it to its substantially median position.
  • the single figure in this drawing is a simplified general view of a dobby comprising a damping system produced according to the invention.
  • a known manner it comprises a control unit 1 that prints to an arm 1 has a reciprocating oscillating movement.
  • the free end of the arm 1 a is articulated to a connecting rod 2 which is pivotally connected to the end of the first branch 3 a of a square lever 3 mounted to pivot relative to a horizontal fixed axis 4.
  • a connecting bar 5 which attacks the branch 3 ' a of another lever 3' identical to that 3.
  • the connecting bar 5 comprises a yoke 5 a which cooperates with a link 12 oscillating about a fixed axis 13.
  • a plate in the form of a double T 14 is articulated to the link 12.
  • a series of springs 15, 15 ' which are further hung on a lug 16, respectively 16'.
  • Each of the latter cooperates with an adjustment screw 17, 17 'rotating freely in a fixed ear 18, 18'.
  • system according to the invention can be applied to any oscillating member of a textile machine mechanism, such as example the leaf or comb of a loom which cooperates with the warp and weft threads to clamp the picks together others, or the weft pass launcher of a shuttleless craft.
  • a textile machine mechanism such as example the leaf or comb of a loom which cooperates with the warp and weft threads to clamp the picks together others, or the weft pass launcher of a shuttleless craft.
  • coil springs 15 and 15 'are can be replaced by a flat profile blade with one end is fixed to one of the branches of at least one of the levers 3 while that the other cooperates with an adjustment device linked to the structure fixed.

Claims (3)

  1. Webmaschinenmechanismus von der Art, die für die wechselweise Betätigung eines Fadens oder einer Gruppe von Fäden wenigstens ein Organ (7) umfasst, das mittels einer Stange (5), die zwei Betätigungshebel (3, 3') des genannten Organs verbindet, positiv in eine desmodromische (desmodromique) schwingende Bewegung versetzt wird,
    dadurch gekennzeichnet,
    dass das schwingende Organ (7) mit elastischen Einrichtungen (15, 15') verbunden ist, die auf dieses Organ (7) eine Gegenwirkung ausüben, wobei eine Gelenkstange (12), angelenkt an einer festen Achse (13), durch die genannte Stange verschoben wird, während die genannten elastischen Einrichtungen (15, 15') auf die genannte Gelenkstange eine Rückstellkraft ausüben, die bestrebt ist, diese Gelenkstange in eine im Wesentlichen mittlere Stellung zurückzubringen.
  2. Mechanismus nach Anspruch 1, dadurch gekennzeichnet, dass mit den elastischen Einrichtungen (15, 15') Einstelleinrichtungen (17, 17') verbunden sind, mit denen einerseits die Stärke der Gegenwirkungs-Rückstellkräfte und andererseits der statische Gleichgewichtspunkt des schwingenden Organs verändert werden kann.
  3. Mechanismus nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, dass die elastischen Einrichtungen in Form von zwei elastischen Einrichtungen (15, 15') realisiert sind, angeordnet beiderseits eines Elements (12) und mit diesem verbunden.
