Definitions

  • the invention relates to a method for producing a technical belt from a multi-layer, in particular two-layer, textile fabric according to the preamble of claim 1.
  • Such a belt made of an air-permeable textile fabric is produced in variable lengths (e.g. 150 m) and is used to fluidize dusty goods.
  • the lateral beads forming the fabric edges serve as clamping stops in the fluidization device and must be largely dimensionally stable so that permanent, secure clamping is ensured.
  • Such technical belts are known and are sold by the applicant under the name "FLUITEX”.
  • the beads of the pair of beads are formed on the edge of the fabric.
  • the height and width of each individual bead as well as the total width of the respective belt is specified by the user.
  • the belt is then cut on site according to the section length used.
  • the invention is based on the object of specifying a rational method for producing a textile technical belt of varying width with lateral, dimensionally stable beads running in the warp direction and forming the fabric edges.
  • the method according to the invention it is possible to weave several air-permeable textile belts of different widths simultaneously as a common fabric web, using the full loom width.
  • the specific dimensions of the user are taken into account by the location and the number of filler warp threads, the distance between the beads of a pair of beads determining the width of the textile belt to be produced.
  • the fabric web is then cut in the longitudinal direction between the beads of adjacent pairs of beads, thereby producing a large number of individual belts.
  • the arrangement of the bead-forming filler warp threads between the fabric layers ensures complete integration into the fabric, and depending on the number and thickness of the filler warp threads, bead formation on the top and / or bottom of the fabric is possible.
  • the beads of adjacent pairs of beads are arranged next to one another with a small distance, the fabric web being cut to form the individual technical belts in the narrow fabric section between the beads of adjacent pairs of beads.
  • the cut edges are sealed during the cutting process or afterwards, the bead not being damaged either during the cutting process or during sealing. This ensures high dimensional accuracy of the bead woven into the fabric of the textile belt.
  • the bead-forming filler warp threads woven in between the fabric layers ensure, due to their firm integration in the fabric, a high dimensional stability of the beads, which does not subside even under high clamping forces.
  • the technical belt can thus be firmly fixed in the clamping device of the fluidization device over a long period of operation.
  • a bundle of filler warp threads are preferably woven in, which are expediently arranged irregularly, which results in a stable formation of the bead.
  • the filling warp threads are fixed transversely to the longitudinal direction of the fabric web by the binding chain joining the fabric layers.
  • the separating cut required for separating the woven fabric web between the beads of adjacent pairs of beads takes place in particular between the sections of the binding chain that fix the filler warp threads.
  • the fabric web 1 produced on a loom has a maximum width B, which is limited by the maximum width of the loom.
  • the fabric web 1 consists, in a known manner, of weft threads 9 and warp threads 6, 6a, 7, 7a, 8, 8a, and 10.
  • the fabric web 1 is constructed in two layers, the first fabric layer 1a being composed of a weft thread 9 and a base warp from the warp threads 6 , 6a is formed; the second fabric layer 1b is formed by a weft thread 9 and the warp threads 7, 7a of a further basic warp.
  • the two fabric layers 1a and 1b are joined together by a binding chain with the threads 8, 8a lying firmly on top of each other.
  • the textile fabric web 1 is air-permeable. Plastics such as polyester, aramid or the like are preferably used as the thread material, so that the fabric can be cut thermally. Cotton can also be useful as thread material.
  • each pair of beads consists of two beads 2, 2a, 3, 3a and 4, 4a, which are preferably arranged at different distances.
  • the outer edges 12, 13 and 14 of the beads 2, 2a; 3, 3a; and 4, 4a of each pair of beads have a distance L2, L3 and L4 from each other, which corresponds to the finished size of the textile belt to be manufactured.
  • This finished size is specified by the user, who uses the belt, which consists of an air-permeable textile fabric, to fluidize dusty goods.
  • the user also gives the height and width, possibly also the shape of the beads 2, 2a; 3, 3a; 4, 4a, which are required as clamping stops in a fluidization device, not shown here.
  • the height and width and possibly also the shape of the beads 2 to 4a are determined by one or more filling warp threads 16 which - cf. Fig. 1 - are arranged between the upper fabric layer 1a and the lower fabric layer 1b of the two-layer fabric 1 in the embodiment.
  • Bundles 17, 27, 37 are preferably each arranged on filling warp threads 16, 26, 36, it being possible for approximately 40 to 50 warp threads 16 to be combined in one bundle 17, 27, 37.
  • the warp threads 16 preferably have the same thickness as the base warp 6, 6a or 7, 7a of the fabric layers 1a and 1b.
  • a bundle 27 of thicker filler warp threads 26 which have a larger cross section than the threads 6, 6a, 7, 7a of the base chains of the fabric layers 1a, 1b.
  • the arrangement of the filling warp threads 16, 26 is preferably irregular; a regular arrangement can be particularly useful to achieve a certain bead shape.
  • a mixture of warp threads 16, 36 of different thickness is also possible.
  • the bead-forming filler warp threads 16, 26, 36 or the bundles 17, 27, 37 formed by them are fixed transversely to the longitudinal direction 22 of the fabric web by the binding chain holding the fabric layers 1a, 1b together.
  • the filling warp threads 16, 26, 36 lie between the weft threads 9 of the upper and lower fabric layers 1a, 1b, so that they fill the cavity formed by the weft threads 9 and the binding chain 8-8a.
  • a bulge of height H is produced on at least one outside of the fabric web 1.
  • the arrangement of a bead on only one side of the fabric web 1 can be expedient.
  • a bead is formed on both sides of the fabric web 1, the height H of the bead elevation is preferably the same on both outer sides of the fabric web 1.
  • a different formation of the height H is possible through an increased or reduced number of filler warp threads 16, 26 and 36.
  • the fabric web 1 is cut in the longitudinal direction 22 by means of a cutting device (not shown here) along a cutting line 5.
  • the section line 5 runs approximately centrally between the beads 2a, 3 or 3a, 4 of adjacent pairs of beads 2 - 2a; 3 - 3a or 3 - 3a; 4 - 4a.
  • the cut edge is hot welded during the cut or subsequently by means of a flame or a soldering iron, not shown, in order to prevent the fabric from fraying.
  • the distance 7 between the beads 2a, 3; 3a, 4 is designed to be as narrow as possible so that after the cutting there is no excessively large protruding edge.
  • the distance z is chosen so large that an injury to the section of the threads 8, 8a of the binding chain which fixes the bundles 17, 27, 37 is reliably avoided, so that the bead is not injured when cutting along the cutting line 5.
  • a dimensionally stable bead which is structurally adapted to the clamping device of a fluidization device and which also remains dimensionally stable over a long operating time.
  • the filler warp threads 16, 26, 36 which are firmly woven into the fabric, cannot escape due to the fixation by the binding chain 8-8a and the weft threads 9.
  • the distances L2, L3, L4 which determine the finished size of the textile fabric belts to be manufactured can be the same or different.
  • the number of in A pair of beads to be woven in is determined by the number of belts to be woven at the same time and by the maximum production width of the loom.
  • the width of the loom can be largely fully utilized in each weaving operation, in that the textile belts to be produced are expediently manufactured with a predetermined finished size lying next to one another as a one-piece fabric web.
