Definitions

  • weft pass-through member is constituted by a false shuttle launched through the crowd by two lateral sabers, but which are equipped with two fixed weft reserves while the false shuttle is provided with a wire clamp device suitable for grasping the wire of one reserves at the corresponding edge and to release it at the opposite edge.
  • the wire clamp device generally comprises a small frame 1 which is fixed against the underside of the false shuttle 2 and which extends laterally on the side thereof opposite the leaf of the loom.
  • a jaw 4 On a pivot 3 oriented parallel to the axis of the false shuttle 2 is articulated a jaw 4 which has a complex profile, suitable for defining in cross section: - a mobile jaw 4 is intended to cooperate with a fixed jaw 1 has provided on the frame 1; - A wing 4 b turned away from the jaw 4 a and subjected to the elastic action of vertical pushers 5 which tend to permanently apply said jaw 4 a against the jaw 1 a ; - And a vertical actuating heel 4 c housed with play inside a longitudinal groove 2 a of the body of the false shuttle 2.
  • the opening of the device is carried out using one or the other of the two shoes 6 fixed on the sides of the loom and profiled so as to engage in the groove 2 a of the false shuttle and to come thus wear against the heel 4 c .
  • the whole of the jaw 4 then swings around the pivot 3 against the elastic pushers 5, which has the effect of temporarily separating the jaw 4 a from the jaw 1 a and freeing the weft thread which was pinched between these.
  • the present invention mainly intends to remedy, which essentially consists in associating with the jaw an independent rocking lever which, receiving the action of the fixed control shoes, transmits it with gear reduction to said jaw.
  • the wire clamp device comprises a tilting jaw 14 which, as illustrated in FIG. 3, is integral with two ends of axis 21 oriented longitudinally relative to the axis of the shuttle in order to form pivots for said jaw.
  • each of these ends of the axis 21 is engaged in rotation in one of two perforations 22 a made side by side in dice 22 mounted against the body of the shuttle 12 in order to allow the jaw 14 to tilt.
  • jaw 14 is secured to a movable jaw 14 is adapted to cooperate with the fixed jaw 11 has the above-mentioned.
  • the jaw 14 has a wing 14 b which has imprints 14 ′ suitable for cooperating with the head of pushers 15, two in number in the embodiment envisaged.
  • Each pusher 15 slides in a threaded bushing 23 screwed into a vertical thread of a longitudinal guide 24 which borders on one side of the groove 12 a of the body 12 of the dummy shuttle. Between the end of each bush 23 and the head fulfilling the pusher 15 corresponding is interposed a spring 17 which tends to keep the jaw 14 is applied against the fixed jaw 11a.
  • the jaw 14 has no actuating heel.
  • This is in fact replaced by the vertical wing of a lever 25 with a square profile which, as shown in FIG. 3, is provided with two ends of axis or pivots 26 engaged in the second of the perforations 22 a of each die 22, so that said pivots are placed between the pivots 21 of the jaws 14 and the imprints 14 ′ above-indicated .
  • This lever 25 is thus capable of tilting along an axis parallel to that of the jaw 14, independently of the latter.
  • axle ends 26 are carried by lateral bosses 25a of the lever 25, projections between which engages the flange 14 b of the jaw 14.
  • the flange 14 b has thus bear against a sail 25 b which joins together the two bosses 25 a , as illustrated in FIG. 3, so that the tilting of the lever 25 according to the arrow F of FIG. 2 has the effect of causing the jaw 14 to tilt and the opening of the wire clamp device against the elastic return means 15-17.
  • the operation of the device according to the invention is in itself identical to that of conventional devices, in the sense that when the false shuttle arrives at one or other of its limit switches at level of the edges of the fabric, the hoof fixed 16 corresponding engages in the groove 12 a and controls the lever 25 which operates by tilting the opening of the jaws 14 a and 11 a .
  • the interposition of this double lever 25 between the shoe 16 envisaged and the jaw 14, joined to the positioning of the pivots 26 of said lever relative to the pivots 21 of the jaw introduces into the actuation system a force multiplier effect which allows easy control of the device upon opening despite the resistance exerted on the jaw by the springs 17 associated with the pushers 15 which ensure the elastic closure.
