Definitions

  • the invention relates to a method of manufacturing an elastic ribbon or not, with two mesh edges, simple or worked, the means of implementation and the products obtained.
  • the present invention aims to remedy these drawbacks.
  • the present invention as characterized in the claims solves the problem of creating, by weaving on so-called “hook” or “sickle” looms, quality ribbons whose mesh edges, simple or worked, have a beautiful regular appearance, without abnormal pulling on the warp threads, nor curling of the edges.
  • a single framing device (or hook or sickle) is used, which is moved transversely, driving a single frame at each stroke and in both directions, and is driven periodically and alternately, at by means of the weigher, beyond one edge or the other of the ply of warp threads, at least one warp thread not aligned inside the tread, we work alternately on a selvedge and on the other the weft, and periodically the warp thread driven, with a needle movable along each selvedge, and we release the warp thread drawn outside and linked to the selvedge when we drive the weft crosswise and the frame.
  • the weft, and periodically the driven warp thread is knitted directly and alternately in the hook of the needles which work along the selvedges.
  • At least one elastic or non-elastic filler wire is used on each selvedge, this wire being driven in relation to the weft yarn and the warp yarn drawn transversely.
  • the weaving loom known as “with hooks” or “with sickles” illustrated in FIGS. 1 to 5, essentially comprises a support frame 1 whose lateral sides 1a carry each a plate 2 intended to serve as a bearing for upper shafts 3 and 4.
  • intermediate bearings can be arranged, in order to avoid any bending.
  • Trees 3 and 12 on the one hand, and the eccentric axes 6 and 10 on the other hand, constitute a deformable parallelogram, and it should be noted that the crankpins 6a-1 Oa are offset by 180 degrees relative to each other to ensure the alternating translations of the selvedge mesh needles, the detail of which is described below.
  • a drive shaft 13 transmits the rotation movement according to arrow F1, to the eccentric axis 10, by means of a well known kinematics, with, in an intermediate manner, at 14, also the conventional control of a gearbox with cams (not shown) intended to move in alternative translations the threading frames 15 carrying the heddles of warp threads, according to the weaving phases.
  • a rod 20 in two parts, the other end of which is articulated at 21 at the rear of the block 16, while another rod 22, in two parts, and wedged on the shaft 4 parallel to the shaft 3, is articulated at 23 at the front of the block 16.
  • This deformable parallelogram construction enables alternative translations (arrow F3) of the block 16 carrying the needle 18 intended to mesh the right selvedge ( Figure 4) of the ribbon R which runs between this needle and the needle 19 of the left selvedge mesh ( Figure 5) whose carrier block 17 is connected to articulation, on the one hand to the 'rear at 24, to a link 25 wedged on the shaft 12, and secondly, at the front at 26, to a link 27 articulated on a support 28, in order to constitute another deformable parallelogram.
  • Said support is carried by a rod 29 integral with a bracket 30, the sole 30a of which is fixed to the frame 1.
  • a drive shaft 31 transmitting by appropriate kinematics, its rotational movement (arrow F4) to a pulley 32 wedged on a shaft 33 carried by the frame, and on which a crankpin 34 controls two rods 35-36 connected to articulation with rods 37-38 wedged on shafts 39-40.
  • the shaft 40 crosses the loom and carries a comb 41 (as many combs as there are ribbons to be produced) for sorting and packing the weft threads, while the shaft 39 carries a toothed sector 42 cooperating with a pinion 43 wedged at the end of an axis 44 carried by the bracket 30 ( Figures 4 and 5).
  • tramter or sickles 45 On the axis 44 is wedged the tramter or sickles 45, it being understood that there are also as many tramplers and members for their control (pinions 43, toothed sector 42), as there are ribbons to be produced.
  • the single screen 45 comprises a pivot 45a of angular connection with the axis 44, a spacer arm 45b at the end of which extend along curves approximately superimposed around the pivot, two branches 45c-45d.
  • the upper branch 45c has at the free end, an eyelet 45e for passage of the weft thread, and between the arm 45b and said end, the branch 45c carries below (on the side of the lower branch), a projection 45f directly formed or attached, and suitably oriented to retain and drive under the operating conditions described below, a warp thread.
  • the lower branch 45d, longer than the branch 45c has at the end a projection 45g similar to the projection 45f, but located above (on the side of the upper branch) and also intended to periodically retain and drive a warp yarn.
  • the warp threads A3, elastic or not, cut by donor systems, are conventionally divided into two layers N1-N2 ( Figures 9 and 11), by means of the heddles of the threading frames 15 and guided in the comb 41 , while an A4 weft thread located at the edge of the comb (to its right), is connected to the eyelet 45e of the single screen 45.
  • the filler wires A1-A2 are also located to the right and left of the comb and pass through the eyelets 46a-47a of levers 46-47 articulated on each side of the ribbon, substantially in front of the bar 48 bearing on the woven tape, or approximately at the hooks of needles 18-19 when they are in the maximum front position ( Figures 9 and 11).
  • the ribbon is woven in a conventional manner, that is to say by knitting or knotting the A1-A2 filler threads if necessary. , with the weft A4, on each side of the ribbon, in combination with the crossing of the plies N 1 -N2 of warp thread A3 and with the needles 18-19.
  • one of the warp threads located near the left border (the second in the example illustrated in FIGS. 12 and 13) is kept substantially in the middle of the gait by controlling its frame. threading (between the two layers N1-N2), to be hooked and driven by the projection 45f located under the branch 45c of the tra meur 45 moved along arrow F5 (FIG.
  • the warp thread A5 which has been pulled beyond the edge, when it is released by the weigher, resumes by elasticity, substantially its initial position by pulling the warp thread (s) A3 located between it and the border, which causes at this location E ( Figure 13), a withdrawal of the tape relative to the border.
  • This shrinkage is all the more important as the number of warp threads A3 located between the thread A5 and the edge, or the distance between the edge and said thread A5, is important, which gives the depth of the festoon.
  • the festoon on the right edge can be made in the same weft stroke or after a certain number of weft strokes, in the same way as for the left edge.
  • a warp thread A6 (the second in the example illustrated) is held substantially in the middle of the walking to be hooked and driven by the projection 45g of the branch 45d of the tramway, following the weft thread A4.
  • the two selvedges can be identical or worked differently, for example, the scallops can be equal in size and in appearance, or different in appearance, whether or not there is a filler wire, or by the distance between the edge of the ribbon and the warp thread driven by the weft, or the number of warp threads located between the edge and the wire driven by the weft.
  • the drive points (protrusions 45f-45g) of the warp threads A5-A6 are determined on the branches of the tramway, according to its axis of rotation lateral to the ribbon, which means that the lower branch has to be extended, so that the warp threads A5-A6 are not excessively drawn beyond the edge, which would bring risks of breakage or permanent deformation of said threads, but also to pull said warp threads sufficiently outside the ribbon, according to its width.
  • the means are simple in their design, assembly and operation. Manufacturing is more economical and the products have an attractive cost price.
  • the use of the two needles prevents slipping and tightening of the warp threads which are near the selvedges, by a frictional effect of the weft during the recalling of the weigher.
