Definitions

  • the present invention relates to dobbies and other mechanical armor of the negative type for the formation of the crowd on weaving machines, and it relates more particularly to pulling systems intended to operate the control of heald frames associated with such mechanical.
  • the elastic means associated with each heald frame are most often constituted by two series or "registers" of parallel springs 1; in each register, these springs are retained between a rack 2 fixed to the structure 3 of the weaving machine and a clip 4 articulated at 5 on an oscillating lever 6, which is carried by a horizontal axis or pivot 7 integral with said structure 3
  • an operating cable 10 which is fixed laterally to the frame 8 to be controlled and whose free end, suitably returned, is hooked to the corresponding movable member of the armor mechanism.
  • the main cable 10 is found, but the latter is fixed on an oscillating lever 11 of a particular type, which is connected to the clip 4 of the corresponding register of springs 1 by a flexible cable-shaped member 12.
  • the secondary cable 12 is wound in a groove or slot 11a formed in the periphery of the lever 11 concentrically to the pivot axis 7.
  • One end of this cable 12 is secured to a bracket 13 (Fig 2) suitably retained on the clip 4, while the opposite end comprises an end piece 14 (fig. 3) housed in the groove 11 a and provided with a threaded rod which is screwed into a radial thread of a cylindrical core 15.
  • the latter receives in the same way an identical end piece 14 housed in the opposite groove 11 b of the lever 11 which guides the main cable 10, this second end piece 14 being fixed at the end of it.
  • the core 15, suitably supported laterally, is thus capable of coming to engage in a semi-cylindrical cradle 11 c formed in the periphery of the lever 11, between the adjacent ends of the grooves 11 a and 11 b .
  • each clip 4 and the springs 1 which are attached to it are driven by a perfectly linear alternating vertical movement, without any transverse component capable of generating parasitic oscillations, regardless of the speed of this alternating movement.
  • each lever or pulley 11 is joined to the heddle frame 8 to be controlled by an adjustable rod 18 associated with a crank pin 19 radially integral with said lever or pulley 11.
  • the horizontal orientation of the spring registers 1 allows the implantation of said registers in the part, most often not crowded, of the weaving machine which surmounts the heald frames 8. This horizontal orientation is obtained thanks to the adoption of cables secondary 12 and their winding on a bearing of the levers 11 concentric with the axis of rotation 7 thereof, and thanks to the mounting of the spacers 17 between the springs 1.

Claims (6)

1. Zugsystem zur Steuerung von Schaftrahmen von negativen Schaftmaschinen der Art, die für jeden Rahmen zwei oszillierende Hebel (11) umfaßt, von denen jeder auf der einen Seite über ein Hauptkabel mit der Schaftmaschine (16) und dem Rahmen (8) und auf der anderen Seite mit wenigstens einer Reile von Rückstellfedern (1) oder einem "Register" verkuppelt ist, dadurch gekennzeichnet, daß die Verbindung zwischen jedem oszillierenden Hebel und dem entsprechenden Register durch ein flexibles Element oder ein Sekundärkabel (12) sichergestellt ist, das sich auf einem Teil (11a) des Hebels aufrollt, der konzentrisch mit der Drehachse (7) desselben ist.
2. System nach Anspruch 1, dadurch gekennzeichnet, daß die Vertäuung der beiden Kabel (10, 12) auf dem oszillierenden Hebel (11) mit Hilfe einer Seele (15) durchgeführt wird, die mit den beiden Kabeln verbunden ist und die in einem entsprechenden, in die Peripherie des Hebels gearbeiteten Schlitten (11c) eingefügt ist.
3. System nach Anspruch 2, dadurch gekennzeichnet, daß das Ende jede Kabels (10, 12) mit einem radial in die Seele (15) geschraubten Kabelschuh (14) versehen ist.
4. System nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Peripherie des oszillierenden Hebels (11) mit Vertiefungen oder Rillen (11a, 11b) ausgehöhlt ist, die Führungen für das Aufrollen der beiden Kabel bilden.
5. System nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß jedes Federregister (1, 20) im wesentlichen horizontal ausgerichtet ist und mit Zwischenelementen (17) versehen ist, die zwischen den verschiedenen Federn eingesetzt sind, um ihre Berührung während des Betriebs zu verhindern.
6. System nach Anspruch 5, dadurch gekennzeichnet, daß die beiden Sekundärkabel (12), die mit ein und demselben Schaftrahmen (8) verbunden sind, mit den gegenüberliegenden Enden eines einzigen Registers (20) zusammenwirken.
