Definitions

  • the invention relates to a weaving rotor with pneumatic weft insertion, in particular for row shed looms, with at least one weft insertion comb consisting of lamellae, which lamellae surround the weft channel except for a weft outlet.
  • the invention has for its object to provide a weaving rotor of the type defined in the introduction, the lamellae of the weft insertion comb being used to form relay nozzles and passive nozzles.
  • This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous further developments.
  • a weaving rotor 1 has on its circumference a number of weft insertion combs 2 running in the longitudinal direction, which, as is known, alternate in the circumferential direction with (not shown) stop combs.
  • the direction of rotation of the weaving rotor is indicated by an arrow 3.
  • the weft insertion comb 2 consists of a groove 4, which is attached to the weaving rotor, and a large number of lamellae arranged therein.
  • the slats are lined up on two rods 6 and 7 running in the longitudinal direction through the channel 4.
  • the slats delimit a weft channel 8 for a weft thread 9.
  • the lamella 10 has a projection 13 in the weft direction, which surrounds the weft channel 8 with the exception of an outlet opening 14 for the weft thread 9.
  • the lamella 11 has a projection 15 which is directed opposite the projection 13 and surrounds it concentrically with the exception of the outlet opening 14. Since the projection 13 has a smaller diameter than the projection 15, an annular gap 16 remains between the two.
  • the spacer 12 has two webs 17 and 18, which on the one hand determine the distance d between the two lamellae 10 and 11, and on the other hand an air supply duct 19 with a depth t limit.
  • the air supply duct 19 is connected via a bore 20 in the trough 4 to a chamber (not shown) filled with compressed air in the weaving rotor 1.
  • a recess 21 in the spacer 12 surrounds the projection 13 at some distance and approximately concentrically, so that a cavity 22 arose.
  • the projection 15 of the lamella 11 has a cutout 15 'through which the air supply channel 19 is connected to the annular gap 16, so that the compressed air supplied from the weaving rotor can flow from the annular gap into the weft channel 8 and convey the weft thread 9.
  • the described arrangement formed from two adjacent lamellae is a so-called relay nozzle.
  • lamellas form relay nozzles in pairs; there is only one relay nozzle about every 50 mm in length of the weft insertion comb 2.
  • the lamellas in between form passive nozzles constructed in pairs in the same way, ie they are not pressurized with compressed air, so that they do not contribute to the conveyance of the weft. Due to their conical projection 13, they act bundled on the conveying air flow in the firing channel 8, so that the mutual distance between the relay nozzle can be chosen larger. It should be noted here that the lamellae of the passive nozzles need not be connected to one another by a spacer 12 since they do not carry compressed air.
  • the projection 15 of the lamella 11 serves as a support surface for the warp threads 23 when they are in a high position.
  • the slats 10 and 11 are provided in the region of the lower side 14a of the weft thread exit opening 14 with bends 25 and 26 facing one another. These prevent the warp threads from sticking to the slats when the warp threads are immersed in the deep compartment.
  • the projection 13 facing the firing channel 8 can be provided in the region of the outlet opening 14 with extensions 27 and 28 which extend in the direction of the outlet opening. These continuations prevent the blown air from escaping radially into this area.
