Definitions

  • the present invention relates to the dobbies of the negative type for training the crowd on the looms, and it relates more particularly to the mooring of the pulling cables on the suspension levers associated with the heald frames.
  • Fig. 1 is a very schematic view illustrating the installation of a negative type dobby, the suspension levers of which are fitted with mooring systems according to the invention.
  • Fig. 2 shows, prior to their assembly, the various elements of one of these systems.
  • Fig. 3 reproduced fig. 2 after assembly and assembly of the elements in place.
  • Fig. 4 is a side view with longitudinal cutaway.
  • Fig. 5 is a cross section along the plane indicated in V-V in FIG. 4.
  • Fig. 6 and 7 illustrate in section two variants for retaining the support pad against the end edge of the suspension lever.
  • Fig. 8 shows the application of the invention to a suspension lever associated with a single pulling cable.
  • reference 1 designates one of the heald frames mounted on a weaving loom.
  • the vertical operation of each frame 1 is ensured by two pulling cables 2 which are returned by pulleys 3 to moor to one of the suspension levers 4 of the dobby 5 installed on an upper structure 6 of the loom.
  • it is a negative dobby in which each suspension lever 4 is actuated, against the reaction exerted on each frame 1 by return springs 7, by a mechanism 8 of the balance.
  • This system comprises firstly, at the terminal edge of the lever 4, a rib or fin 4 a provided thinned in the embodiment considered, which rib is oriented longitudinally and is pierced with a transverse opening 4 b .
  • a small axis 10 which is retained axially by crimping, by force engagement or by welding. It will be observed that below the rib 4 a , the edge of the lever 4 is established at a curved profile and comprises a series of depressions 4 c , three in number in the exemplary embodiment envisaged.
  • the mooring system also includes a support pad 11, advantageously made of molded synthetic material.
  • the pad 11 in cross-section a U-shaped profile which opens downwardly defining two lateral wings 11a together upwardly by a central web 11b.
  • the outer surface of the disc 11 b is cut with two longitudinal grooves 11 c while the opposite face, arranged between the flanges 11a, comprises three bosses 11 d.
  • the shoe 11 has a profile complementary to that of the terminal edge of the lever 4, in order to be able to bear against it, in the manner which will be described later.
  • each eyelet 12 is pierced transversely at 12 b to allow it to be hung on the axis 10.
  • the shoe 11 is capable of being mounted on the terminal edge of the lever 4 envisaged, the raised parts formed by the bosses 11 d coming to cooperate with the depressions or hollow parts 4 c of said edge.
  • the axis 10 having been assumed to be placed in the opening 4 b of the rib 4 a , it suffices to introduce each eyelet 12 on the said axis through its hole 12 b .
  • the traction exerted on the cables 2 keeps them in the grooves 11 c of the shoe 11, which is thus firmly retained in place by interpenetration of the parts 4 c and 11 d .
  • the upper end of this shoe 11 is provided with two lateral nozzles 11 e which are positioned and profiled so as to come to be arranged slightly below the axis 10, thereby ensuring the retention of the eyelets 12 on said axis.
  • each suspension lever 4 is associated with two pulling cables, it is nevertheless capable of being applied to the dobbies in which each lever suspension 4 ′ ensures the operation of a heald frame 1 using a single cable 2.
  • the rib 4 ′ a can be profiled in the manner of a hook to enter the opening 12 ′ b of a closed eyelet 12 ′ crimped at the end of the cable 2.
  • the support pad 11 ′ does has only one longitudinal groove or guide 11 ′ c .
