Definitions

  • a movement control mechanism back and forth from two claw frames from one trade to weaving is known, for example, from document DE-C-899 929 as well as CH-A- 433 139.
  • a crowd training system for a trade tape must have the most space small possible in length so as to decrease overall dimensions and moving masses.
  • the invention comprises on each side of its frame, at minus a set composed on the one hand a first lever articulated to this frame by one of its ends and to one of the claw frames by its opposite end, while said lever is associated with a command reciprocating and secondly a second lever whose ends are articulated respectively said claw frame and to the frame so that the latter, the two levers and the frame constitute a parallelogram irregular deformable, in order to communicate to it a movement such that in the high position it is oriented obliquely from its low position.
  • the distance between the axes of articulation of the two levers to the frame can be greater at the spacing between their axes of articulation to the frame.
  • each of the claw frames is arranged on either side of the frame 1, so that each frame of claws is cantilevered by compared to its control mechanism.
  • This provision is made possible by the fact that the width of frame 1 is weak when dealing with mechanics intended for the manufacture of narrow ribbons on a loom.
  • the frame 1 is crossed by a control shaft 3 rotating in synchronism with the control one of career.
  • This tree protrudes on each side of the frame to carry an eccentric 4.
  • Each eccentric constitutes a crank pin around which is rotatably mounted the head of a connecting rod 5 whose foot is articulated on an axis 6 integral with the top of a lever 7 of shape general triangular.
  • One end of the lever 7 is articulated with respect to the frame 1 around an axis 8, while its opposite end is articulated to the frame 2 via an axis 9.
  • Frame 2 is still connected to the frame by a second lever 10 whose axis hinge 11 on this lever is at a distance d below the hinge pin 9 of the lever 7 and which is different from that D separating the axis 8 from the axis 12 for pivoting the lever 10 relative to the frame 1.
  • the set of two levers 7 and 10 constitutes by therefore an irregular deformable parallelogram.
  • the connecting rod 5 causes a pivoting of the lever 7 around the axis 8. Because the presence of the lever 10, the frame 2 moves so in such a way that in the high position, illustrated in solid lines, it is oriented obliquely relative to its low position shown in broken lines.
  • the angular movement has lever 7, illustrated by the mixed lines 13, 14 uniting the centers of axes 8 and 9, causes the oblique displacement of the frame 2 upwards, so that the knives this frame which are arranged according to the mixed line 15, lie in a plane oblique to that in which they are located when frame 2 is at its low position.
  • lever 7, illustrated by the mixed lines 13, 14 uniting the centers of axes 8 and 9 causes the oblique displacement of the frame 2 upwards, so that the knives this frame which are arranged according to the mixed line 15, lie in a plane oblique to that in which they are located when frame 2 is at its low position.
  • eccentric 4 which controls the frame 2 is offset 180 ° from that which controls the second frame, not shown, so that these two organs move alternately in reverse directions in the known manner.

Claims (2)

  1. Steuermechanismus zur Hin- und Herbewegung der beiden Messerkästen einer Fachbildungseinrichtung des Jacquard-Typs eines Webstuhls, welcher Mechanismus auf jeder Seite seines Gehäuses (1) wenigstens eine Anordnung aufweist, die einerseits zusammengesetzt ist aus einem ersten Hebel (7), der an dem Gehäuse durch eines seiner Enden und an einem der Messerkästen durch sein entgegengesetztes Ende angelenkt ist, während der genannte Hebel (7) mit einem eine Hin- und Herbewegung ausführenden Antrieb (3, 4, 5) in Verbindung steht, und die andererseits mit einem zweiten Hebel (10) verbunden ist, dessen Enden an dem genannten Messerkasten (2) bzw. dem Gehäuse (1) angelenkt sind, so dass letzteres, die beiden Hebel (7, 10) und der Messerkasten (2) ein verformbares, unregelmäßiges Parallelogramm bilden, um auf dieses eine solche Bewegung zu übertragen, dass es dann, wenn es sich in der oberen Lage befindet, in Bezug auf seine untere Lage schräg ausgerichtet ist.
  2. Mechanismus nach Anspruch 1, dadurch gekennzeichnet, dass der Abstand (D), der die beiden Anlenkungsachsen (8, 12) der beiden Hebel (7, 10) an dem Gehäuse (1) trennt, sich von dem Abstand (d) unterscheidet, der zwischen den beiden Anlenkungsachsen (9, 11) mit dem Messerkasten (2) vorhanden ist.
