Definitions

  • the invention relates to a device for inserting a weft yarn for a loom with two superposed sheets, and to a loom equipped with such a device.
  • double-ply looms In the field of double-layer weaving looms, sometimes referred to as “double-ply looms", it is known, for example FR-A-2552455 inserting the weft threads in the crowds defined by the loom by means of rigid lances whose heads are guided, on the one hand, by integral parts of the comb of the loom and, on the other hand, by the comb. These rigid lances have such inertia that their respective drive means must be able to develop significant power, which makes them expensive.
  • the guide means provided in the vicinity of the comb are capable of interacting only with the claws of the lances, which means that, in the case of looms with a large blade width, the lances are guided only on a small part of their length when fully deployed. They must therefore have a relatively high rigidity, which is penalizing in terms of mass and inertia. In addition, these lances impose a significant lateral bulk for the craft.
  • the invention more particularly intends to remedy by proposing a weft insertion device for a loom with two superposed sheets through which the lances can be efficiently guided, while the inertia of the parts in movement can be optimized.
  • the invention relates to a device for inserting weft threads for a loom with two superposed sheets, this device comprising flexible lances. provided with weft yarn feed dogs in a shed and a movable comb between a rear position, compatible with the insertion of weft yarns into the shed, and a striking position.
  • Each lance comprises a claw and a flexible part partially wound on a drive wheel, while each wheel rotates about a fixed axis relative to the frame of the loom and that the comb assembly is equipped with means, distributed according to the width of levee, guiding the flexible part of each lance.
  • the guide means are divided into two series, a first series of which is connected to the comb in the vicinity of its upper part and the second series of which is connected to the comb in the vicinity of its lower part, the first series being dedicated to guiding the part flexible of the upper lance (s), while the second series is dedicated to guiding the flexible part of the lower lance (s).
  • the guide means are able to guide the flexible parts of the lances without them interacting with the teeth of the comb.
  • the series of guide means are each formed by a succession of tabs distributed along the length of the comb and each defining a passage orifice of which at least a portion is substantially complementary in shape to that of the section of the flexible portion of the corresponding lance this passage opening having a shape adapted to guide the flexible portion. At least one of the orifices is provided with an opening for the passage of a junction part between the flexible part and the claw of a lance, such an opening being oriented towards the teeth of the comb.
  • the lances can be effectively guided on most of their trajectory in the crowd through guiding means that interact not with the single claw of each lance, but with its flexible portion or ribbon that extends over most of this trajectory when the spear is fully engaged in a crowd. Since the drive wheel of the flexible part of each lance is not driven by the comb assembly, this assembly is lighter and easier to use. lead.
  • the distribution of the guide means in two distinct series allows to arrange the guide means so that the position of the trajectory of the lances in the crowd is optimized. Since the guiding means are sufficient to guide the flexible parts or strips of the lances alone, these flexible parts are not likely to wear in contact with the front edges of the teeth of the comb.
  • the stroke of the comb must be sufficient so that, when the latter is in a rear configuration compatible with the introduction of a weft thread, the means for supporting the claws are arranged generally inside the body. crowd, whereas, in striking position, these guide means are arranged outside the crowd.
  • This relatively important race requires in practice to increase the distance between the points of striking and the smooth closest to these points of striking.
  • Such a rail can be mounted on a smooth frame or controlled by a Jacquard harness.
  • the greater this distance the longer the race of the pile yarns and warp threads is long, which induces significant stresses on the drive devices and in practice limits the speed of operation of a loom equipped with of these devices.
  • the comb when in the rear position, is located entirely between a plane containing the striking points and a plane perpendicular to the sheets of cloth before their separation, this perpendicular plane passing, for each tooth of the comb, by a point located, relative to that of the points of the front edge of this tooth intended to bear against the points of striking which is furthest from these points of striking at a distance equal to five times the width of the tooth at that particular point of its leading edge.
  • the shape of the comb minimises the distance between the impact points and the control strands of the pile and warp threads, which makes it possible to reduce the maximum strokes that the Jacquard machine has to print to the pile threads or that the fundamental armor mechanics must print to the warp threads.
  • the invention also relates to a loom with two superposed webs equipped with a weft thread insertion device as mentioned above.
  • Such a loom is more economical, easier to install and adjust than trades of the state of the art. It can also operate at a higher speed.
  • the trade M represented to figures 1 and 2 is intended for the formation of two plies N 1 and N 2 of tissues, for example two carpets T 1 and T 2 woven simultaneously and separated from each other by a knife 1 hair cutter carried by a carriage 2 and arranged downstream of two strike points P 1 , P 2 towards which converge respectively two crowds F 1 , F 2 defined by the warp yarns 4 of the loom whose vertical movement is controlled by heddles 3 actuated by a Jacquard harness as well as by warp yarns 4 'whose vertical movement is controlled by healds mounted on heald frames 3', themselves driven by a dobby or a cam mechanism not shown.
  • ⁇ 1 is a median plane of the plies N 1 and N 2 between the points P 1 and P 2 and their separation zone by the knife 1.
  • the plane ⁇ 1 is, in practice, substantially horizontal.
  • the weft threads 5 1 and 5 2 intended to constitute, with the corresponding warp threads, the plies N 1 and N 2 are inserted into the crowds F 1 and F 2 by means of two lances 11 and 12 each comprising a head or claw 111, respectively 121, on which can be hung a weft thread 5, and a flexible strip 112, respectively 122, for driving the corresponding claw in the direction of two axes Y 1 , respectively Y 2 , parallel between them and perpendicular to the wires 4 and 4 'and to the plane of the figure 1 .
  • An assembly 13 forming a comb and movable pivotally about an axis Y 3 parallel to the axes Y 1 and Y 2 comprises a leaf 131 and a comb 132 consisting of a row of teeth mounted on the leaf 131 and driven by the in rotation around the Y axis 3 .
  • the teeth 132a of the combs 132 can thus be brought in abutment against the points P 1 and P 2 , as shown in FIG. figure 2 where the leaf 131 has been pivoted about the axis Y 3 , relative to the position of the figure 1 by means not shown and known per se.

  • the profile 135 is made of light metal alloy, in particular based on aluminum.
  • Each tab 133 is pierced with an orifice 133a comprising two extensions 133a 1 and 133a 2 of substantially complementary shapes of the upper and lower portions of the cross section of the strip 112, which makes it possible to obtain a guiding effect of the strip 112 which constitutes the flexible portion of the lance 11, according to the width of the upper, as the claw 111 progresses towards the side of the comb 132 ópposed to that through which it enters the crowd.
  • the shape of the orifices 133a thus makes it possible to guide the ribbon 112 without interaction or contact between the lance 11 and the teeth 132a, which avoids premature wear of the ribbon 112 or the claw 111 by friction against the front edges 132b of the teeth 132a.
