Definitions

  • the invention relates to a weaving rotor for a series shed loom according to the preamble of claim 1.
  • a weaving rotor of this type is described, for example, in the patent specification CH-A-543 621.
  • This weaving rotor has weft insertion combs, the lamellae of which have lamellae which, when viewed in the axial direction of the weaving rotor, are aligned on a line.
  • a disadvantage of this aligned arrangement of the insertion combs is that when the warp threads are grasped, all the lamellas always immerse into the warp thread family at the same time, which, particularly with higher warp thread densities, can lead to warp threads being pushed into an incorrect position, i.e. H. instead of being raised to the top, stay low or vice versa, which leads to weaving errors.
  • the individual warp threads are also subjected to higher mechanical loads when the slats are immersed at the same time.
  • the object of the invention is to provide a weaving rotor with holding elements, d. H. Weft insertion combs to create, which largely excludes misalignment of warp threads in the compartment with gentle handling of these warp threads.
  • a holder 5 which extends over the length of the weaving rotor.
  • Several such holders are regularly distributed over the circumference.
  • Each holder 5 has a weft insertion comb 6 and a weft stop comb 7.
  • the entry comb 6 consists of a number of slats 8, which in groups 9 (Fig. 1) of z. B. five slats are arranged, and slats 10, (Fig. 4), each of which is a slat between two adjacent groups.
  • the slats 8 and 10 are fastened in a groove 12 of the holder 5 by means of a silicone casting compound 11. Both fins 8 and 10 are ceramic compacts.
  • the slats 8 have a fastening section 15, a weft guide section 16 and a warp guide section 17.
  • the fastening section 15 has an elongated recess 20, a lateral recess 21 in one side 22 and two lateral recesses 23 and 24 in the opposite side 25.
  • the lateral recesses 21, 23 and 24 each have recesses 26, 27 and 28 in the side walls 29 or 30 of the groove 12 opposite.
  • a groove 32 is made in a bottom 31 of the holder 5. All the grooves mentioned are filled with the silicone casting compound 11.
  • the weft guide section 16 of the slats 8 has a weft opening 35 and a weft exit openings 36 connected thereto.
  • the weft openings 35 of all the slats 8 together form a weft channel 37 for a weft thread 38, the outlet openings 36 a weft thread exit gap 39.
  • the warp thread guide section 17 of the slats 8 consists of two projections 40 and 41 which delimit a passage 42 for warp threads between them.
  • the bottom of the passage 42 forms the support surface 46 for the warp threads 47, which must be in the high shed position.
  • the contact surface 48 has an opening 48 ′ and an outlet 48 ′′ for the warp threads 47.
  • the projection 40 When the weaving rotor 1 rotates in the direction of arrow A, the projection 40 is located on a leading side 50, the projection 41 on a trailing side 51 of the lamella 8.
  • a point of immersion 52 of the leading projection 40 in the chain is higher than seen in the radial direction Immersion point 53 of the trailing projection 41.
  • the greatest radial height of the immersion point 52 of the leading projection 40 is due to the radial, highest point 7 "of the stop lamella 7 'of the stop comb 7, in that it must be smaller than this.
  • Both immersion points 52 and 53 are spaced apart in the circumferential direction, which results in a large inlet area 54 between the two projections 40 and 41, which ensures that the warp threads are correctly controlled by the warp thread control device.
  • the lamella can be made of a different material, e.g. B. consist of a light metal and be provided with a layer of ceramic or another smooth and hard material. Such a lamella can also be provided with such a layer only in the warp thread guide section 17.
  • the lamella can have a separate warp thread guide section.
  • This warp thread guide section can be a compact or a coated part. 1 is one such division of the lamella is indicated by a dividing line 55 between the warp thread guide section 17 and the weft thread guide section 16. Both parts can e.g. B. by gluing or a connector.
  • slats can be connected to one another for authenticity, e.g. B. by simultaneously pressing the molding compound.
  • the slats of a group 9 in FIG. 2 can be combined to form such a unit.
  • the slats 10 are largely identical to the slats 8, only a fastening section 57 and a weft guide section 58 are made narrower on a trailing side 59 below the weft opening.
  • the resulting partial shot opening 60 is aligned with the firing channel 17 formed by the slats 8.
  • a relay nozzle 62 In the created space 61 there is a relay nozzle 62, the air outlet opening 63 of which extends into the firing channel 17 and points in the direction of its entry.
  • the lower end 64 of the nozzle 62 is located in a longitudinal channel 65 in the weaving rotor 1.
  • One or more nozzles can open into a longitudinal channel.
  • Each longitudinal channel 65 is connected via a bore 66 to a switching tube 67 within the weaving rotor, the interior 68 of which is connected to a compressed air source.
  • a switching tube 67 within the weaving rotor, the interior 68 of which is connected to a compressed air source.
  • one or more relay nozzles are connected to this air pressure source via bores 69 in the switching tube.
  • the holder 5 On the side of the flanks of the lamellae 8 and 10, the holder 5 has bevels 70 and 71, respectively, which serve to facilitate the pouring in of the silicone casting compound 11.
  • the advantage of using silicone is that it can easily be cut out locally once it has hardened, so that any damaged lamella can be removed. The replacement lamella can be attached quickly and easily by pouring silicone casting compound.
  • the weft stop comb 7, which is not the subject of the invention, is mounted in a groove 75 of the holder 5. However, it can be installed in a separate holder.
