Definitions

  • the present invention intends to remedy, and this by proposing a mechanism of the general type described in the document FR-A-2677380 cited above, but in which the funicular organs which carry the knives for controlling the hooks actuation are animated by a race which decreases parallel to the plane of movement of the warp threads.
  • the JACQUARD mechanism according to the invention is defined in claim 1.
  • the reciprocating drums which drive the funicular organs supporting the control knives are set at diameters which are decreasing, while the alternating rotation of these drums is carried out using the same longitudinal member which is driven by an oscillating movement and which is linked to each of the drums to be driven.
  • FIG. 1 shows in perspective the general arrangement of a mechanism established in accordance with the invention.
  • Fig. 2 is a view similar to FIG. 1, the fixed frame having been removed from the representation in order to make the drive device appear better.
  • the mechanical frame shown in fig. 1 comprises a lower base 1 made integral with two vertical flanges 2, oriented parallel to one another. Each flange 2 is associated with an upper cheek 3 which extends parallel to the envisaged flange and which is fixed to the latter by means of transverse connecting rods 4. It is between the two flanges 2 that the modules 5 for actuating with the aid of movable hooks 5a provided on opposite sides of said modules, arcades for the vertical control of the warp son.
  • These modules 5, advantageously of the type described in document FR-A-2586432 (STAUBLI-VERDOL), are arranged side by side in a series of parallel rows oriented transversely to the axis of the flanges 2.
  • each connecting rod 4 which is between the opposite faces of a flange 2 and its cheek 3 is machined so as to form a support for two drive drums 6, arranged side by side, the mechanics thus being provided with two longitudinal series of sets or pairs of drums 6.
  • each drum 6 are moored, using a clamp such as 6 a , the ends of a funicular member constituted by a belt 7 which is returned by pulleys 8 to wind around the periphery of the drum and to define two vertical strands, the aforementioned pulleys being mounted cantilevered against the outer face of the flange 2 concerned so as to be in line with the envisaged drum.
  • the diameters of the different drums 6 of the mechanics decrease from one end to the other of the latter, in the sense that the two inner drums of the first row of modules have a diameter slightly larger than that of the two outer drums, themselves set at a larger diameter than the two inner drums corresponding to the second row, and so on up to the drums 6 which are mounted at the rear end of the mechanics as as shown in fig. 1 and 2.
  • the oscillating drive of the drums 6 is operated using two longitudinal connecting rods 10 each of which is housed in the space defined between each flange 2 and its cheek 3, c ' that is to say between the two drums 6 mounted on each of the assembly rods 4.
  • Each connecting rod 10 is coupled at 11 to the drums of each of the sets of drums, the radial distance between each rod 4 and the coupling point 11 being identical for all the drums 6, as well as the angle of inclination of the line 11-4.
  • each of the two sets of drums 6 with a larger diameter is articulated at 12 the end of a vertical connecting rod 13 whose lower end is provided with a ring engaged on an eccentric 14.
  • the two eccentrics 14 are wedged on the same shaft 15, driven in a continuous rotational movement by an appropriate motor, not shown.
  • the hooks 5 a can in fact be mounted in any suitable manner.
