Definitions

  • the invention relates to a loom according to the preamble of Claim 1.
  • the weft insertion means feature is broadest here Understood form and includes e.g. such as projectiles, Grippers, contactors, air jets, or other media for Inserting a weft thread into a warp thread Shed.
  • Such weft insertion means are also in large number known.
  • FR-A-2 547 602 is a defenseless weaving machine known in order to avoid the above disadvantages on everyone
  • Leaf tooth guide elements for forming an entry channel are molded onto a weft by means of air jets bring in.
  • this can increase the risk of getting caught of warp threads from untwisted yarns on the blow nozzles not be prevented because these are wider than that Distance between the leaf teeth and thus the warp threads and the latter are from the blow nozzles when pivoting the reed pushed apart.
  • the thickness of the guide elements only the guide elements correspond to the thickness of the leaf tooth very thin and have insufficient stability and can bend and thus the danger of getting sympatheticed out of warp thread parts enlarge.
  • the guide elements are definitely not suitable. Should one the leaf teeth would have to achieve sufficient stability and thus the guide elements are made thicker, so that only a coarser division of the reed teeth is possible would be, whereby only correspondingly coarser tissue is produced let.
  • a weaving machine according to the preamble of claim 1 is known as the closest prior art, in which the reed is provided with a shooter guide, the Store tracks has sliding elements that extend in the direction of Stretch warp threads and engage between the warp threads.
  • the sliding elements are wider than the warp thread spacing.
  • a displacement element arranged, which is at least the same width as the sliding element however, has a greater height than this and forms an alley between the warp threads.
  • the displacement elements form a tip.
  • the displacement elements the warp threads have to be formed for every change of subject pushing apart an alley.
  • This shooter guide can do not correct the problems described at the beginning because they is only suitable for high quality twisted yarns however for parallel yarns that are on the pointed displacement elements would be damaged or destroyed.
  • the object of the invention is a weaving machine of the beginning mentioned type so that parallel threads can be processed and this even if they are not with are provided with a size.
  • the deflection member preferably extends according to claim 2 preferably below the top of the guide element but to below the shed if the reed in the position furthest away from the stop edge of the fabric located.
  • the deflection of the warp threads is improved when the weaving machine is designed according to claim 5.
  • a reed tooth with the integrated guide element can be directly connected to the reed according to claim 9 be. In some cases, however, an embodiment can also be used be advantageous according to claim 10. But it is also conceivable if the guide element according to claim 11 formed in two parts is and a guide element part on the reed tooth and the other is arranged on a separate carrier.
  • FIG. 1 shows the weaving area of a first weaving machine, the one device 2 for forming a shed 4 Warp threads 6 has. From the device 2 to form the In the shed, only strands 8 are shown which open the warp threads 6. and move and thus open, close and the shed change.
  • the warp threads 6 are e.g. from parallel yarns, which are produced in the air swirling process and swirling points included as node 10.
  • the warp threads 6 are brought together on the stop edge 12, on the means of a reed 14 an entered in the shed 4, but not shown weft thread is struck and thus serves to manufacture the fabric 16.
  • the reed 14 consists of individual arranged in a reed T division Reed teeth 18 arranged in a lower carrier 20 and with each other at the upper end by a binding rod 22 are connected.
  • the reed is firmly clamped on the leaf lever 23.
  • Guide elements 24 are also on the leaf lever 23 arranged for guiding weft insertion means 26 serve, which in the present case is an entry band 28 have that between two groove-like recesses 30 in Teeth 32, 34 of the guide element 24 are guided.
  • the Guide element 24 is coplanar with that in the direction of movement lying central plane M of an associated reed tooth 18a arranged, as can be seen in particular from Figure 3.
  • a Deflector 36 present which is integral with the reed tooth 18a is formed.
  • the deflector for the warp threads 6 widens on both sides of the central plane M in the direction 38 of the Weft course so that it starts from the reed tooth 18a forms a wedge-shaped guide for the warp threads and these are moved laterally past the guide elements 24, without the risk that the warp threads on the Guide elements 24 get caught.
  • the deflection member 36 begins below a stop line 40 of the reed 14 and extends at least over the Top of the associated guide member 24 preferably but further down until it protrudes from the shed 4, as shown in Figure 1. Up and down is the deflector 36 with tapered sections 42,44 provided to deflect the warp threads when entering and Easy to extend into the shed. 1 Dash-dotted stop position of the reed the deflector is below the stop edge.
  • the deflector is preferably designed so that the maximum width B of the deflector at most ten times corresponds to the pitch T of the reed tooth.
  • the length L of the Deflector in the direction of movement of the reed 14 is at least half the thickness d of the reed tooth 18a. in the shown example corresponds to the distance A adjacent Deflectors 36 of the double pitch T of the reed teeth 18.
  • FIG. 3 shows further configurations of the deflection element 36 shown. So the reed tooth 18b consists of two along the Central plane M mirror-arranged parts 46, which for Formation of the deflection member 36a have thickened portions 48. The reed tooth 18b is also along the central plane M divided and mirrored. The single ones Parts 50 are made of sheet metal and the deflection members 36b are formed by angled edge areas 52.
  • Figures 4 to 7 show the weaving area of another Weaving machine in terms of weft insertion means 36 is identical to the weaving machine of FIGS. 1 to 3. However, here is the area between the reed tooth 56 and the guide element 54 as a deflector 58. In addition, the reed tooth 56 is not with the reed 60 connected, but is carried by the guide element 54, which is attached to the leaf lever 23.
  • FIG. 8 shows a mixed form between the exemplary embodiment of Figures 1 to 3 and 4 to 7, wherein the guide element 62 is divided into guide element parts 62a, 62b. Of the Guide element part 62b is via a screw 64 with a separate carrier 66 connected, which in turn on the leaf lever 23 of the reed is attached. The other part of the guide element 62a forms an integral part of the reed tooth 68, the deflector 70 in turn between the guide element part 62a and the reed tooth 68 is arranged.
  • Figures 9 to 11 show the weaving area of another Weaving machine, the guide elements 72 being designed in this way are that they use an air jet as a weft insertion means 74 use that of relay nozzles 76 in the guide elements 72 is blown in.
  • Deflectors 78 are integral with the associated reed tooth 80 formed and that analog to the deflector 36b Figure 3.
  • Figures 12 to 14 show the weaving area of another Weaving machine constructed similarly to that of Figures 9 to 11 is, however, in Figures 12 to 14, the guide elements 82 are integrally formed on a reed tooth 84 and the deflectors 86 between the reed tooth 84 and the Guide element 82 are integrally formed.
  • the one for blowing in the air serving relay nozzles 88 are attached to a carrier 90, which in turn is attached to the leaf lever 23 of the reed 14 is.
  • the distance A1 corresponds to adjacent guide elements 82 or the corresponding Reed teeth 84 of the triple pitch T of the reed teeth 84 of reed 14.
