  • the Shed forming organs 5 are in the circumferential direction of the weaving rotor spaced that twelve weft insertion channels for the Result in entry of one weft thread.
  • the stock on a warp beam 6 Warp threads 3 are passed over a deflection tree 7 of the insertion device 4 fed.
  • the insertion device 4 comprises a holding device 11 and a plurality of spaced-apart holders 14, which are a plurality of Place the laying rails 10 so that they can move in the direction B of the weaving rotor 2.
  • Each laying rail 10 is mechanical with a drive device 12 connected.
  • the movement B of the laying rails 10 is so with respect to rotating movement of the weaving rotor 2 is controlled so that the warp threads 3 in High or low positions of the shedding organs 5 are inserted so that forms a shed through which the weft thread can be inserted.
  • the Warp threads loop around the weaving rotor 2 at an angle of approximately 120 °.
  • the finished tissue is placed on a breast tree 8 Tree 9 wound up.
  • the cross section of the weaving rotor 2 shown in FIG. 2 shows the other Shelf-forming organs arranged on the surface 5.
  • On the right side are the Laying rails 10 in guide support 13a, 13b, 13c, 13d and in relation to the Viewing plane slidably mounted in the vertical direction.
  • the warp threads 3 each pass through a recess 10a of the laying rail 10 and are thereby back and forth in a direction B vertical to the observation flexibly guided.
  • Fig. 3 shows the laying rail 10 with guide support 13 in detail.
  • Fig. 4 shows the arrangement shown in Fig. 3 in a section along the line A-A.
  • the laying machine 10 has a plurality of in the direction of the Laying rail 10 spaced recesses 10a or eyelets 10a, which serve to guide the warp threads 3.
  • the recesses 10a are elongated and have two end sections 10b, 10d, and an intermediate guide section 10c.
  • the end section 10b can also be referred to as a threading section 10b, which is used to thread a warp thread 3 into the recess 10a.
  • the web rotor 2 as well as the insertion device 4 with guide supports 13 and laying rails 10 are mutually arranged and designed such that the warp thread 3 during normal operation by the thread guide section 10c runs, as shown in Fig. 3 with the warp thread 3c.
  • the Thread guide section 10c preferably has a relatively narrow Gap width, which gives the advantage that the warp threads 3 with respect to Direction of movement B of the guide rail 10 can be guided very precisely can, and therefore can be inserted very precisely in the specialist organs 5.
  • the warp threads 3 move during weaving from the bottom up.
  • the warp thread 3b has one Thread thickening 3a.
  • the laying rail 10 Due to the narrow thread guide section 10c, the node 3a moves along the laying rail 10 outside the Guide section 10c upwards and takes place in the relatively wide End portion 10d a passage, as shown in Figures 3 and 4 is shown.
  • the laying rail 10 according to the invention thus has the Advantage on that it has a threading section 10b through which the Warp thread 3 is easy to thread that it is a relatively narrow Thread guide section 10c, which allows the warp thread 3rd to guide precisely, and that they have an outlet portion 10d and End portion 10d through which a thread thickening 3a can step through.
  • the warp threads 3 are thus even with existing ones Gaps 3a gently and without an excessive load from the Laying rail 10 passed through.
  • Fig. 5a shows a top view of the preferred embodiments of the recess 10a, which have two end sections 10b, 10d and an intermediate one Guide section 10c, wherein the recess 10a in the region of both end sections 10b, 10d has a greater width than on Guide section 10c.
  • Fig. 5b shows a cross section through an embodiment of a Laying rail 10 with the recess 10a shown in FIG. 5a.

  • the guide support 13 can for example consist of a Be made of plastic. The generated at the deflection points 15a, 15b, 15c This arrangement has little or no effect on the frictional heat Guide support 13, so that an expansion or contraction of the Guide support 13 due to the temperature fluctuations that occur is largely avoided. This allows extremely precise guidance of the Laying rail 10 in the guide support 13.

  • a A plurality of regularly spaced deflecting elements 15 are one Holder 14 held.
  • the warp threads 3 run advantageously in the insertion device 4 in such a way that, as in FIG shown, have two deflection points, the deflection on low-wear deflection element 15 takes place.
  • Warp threads 3 are guided such that the warp threads 3 in the deflection area 15a rest and run in the thread guide section 10c of the laying rail 10.
  • Warp thread 3 at short notice from the normal position described by the Thickening 3a, as shown in FIGS. 3 and 4, along the surface the laying rail 10 slides until it passes through the outlet opening 10d. Then the warp thread 3 automatically jumps back to the normal position back and again runs through the thread guide section 10c.
