Definitions

  • the invention relates to a weaving rotor Stop slats according to the preamble of claim 1.
  • the invention has for its object a Webrotor to create the named disadvantages overcomes.
  • the sub-claim 2 relates to another advantageous one Embodiment of the invention.
  • the task continues solved by a method having the characteristics of Claim 4.
  • the sub-claim 5 relates to a further advantageous embodiment of the method.
  • An advantage of the invention is the fact that the Distance between two stop slats in Direction of the axis of rotation of the weaving rotor is enlarged can be so that a warp thread with increased Reliability between the two stop slats can be inserted. Another advantage is there too see that through the direction of rotation of the weaving rotor staggered stop slats the weft threads evenly struck against a fabric stop edge become.
  • FIG. 1b shows a cylindrical weaving rotor 1 its surface compartment-forming compartment holding elements 4 are arranged, which in the direction of rotation 7 of Weaving rotor 1 running warp threads 6a, 6b-6h in one High position or in a low position bring so that a weft insertion channel 4d arises, through which a weft thread using a fluid such as Air can be entered.
  • a weft insertion channel 4d runs parallel to the shaft 8 of the weaving rotor 1 and extends across the entire width of the weaving rotor.
  • Direction of rotation 7 are on the surface of the weaving rotor 1 alternating shelf holding elements 4 and Stop slats 3a, 3b arranged.
  • the stop slats are as whole stop slats 3a or as half Stop slats 3b executed.
  • the whole Stop slats 3a are designed such that they one completely between the warp threads 6a-6h registered, and immediately before the Weft thread 9b located on the fabric stop edge 9a Effect against the tissue stop edge 9a.
  • Fig. La shows a plan view of the surface of the cylindrical web rotor 1.
  • Compartment holding elements 4 are on the web rotor 1 Compartment holding elements 4 arranged, which protruding parts 4a, 4b, and in between a saddle surface 4c form.
  • the warp threads 6a-6h are attached to the Surface of the weaving rotor 1 placed that a warp thread 6a-6h either over a saddle surface 4c Compartment holding element 4 runs so that the warp thread is a Occupies a high position, or such that a Warp thread 6a-6h between two compartment holding elements 4 runs and occupies a low position. Consequently a loom is formed through which a Weft thread can be entered.
  • the weaving rotor For inserting the warp threads 6a-6h in the weaving rotor serve laying elements 5a-5h, which are movable parallel to the shaft 8 of the weaving rotor 1, and position the warp threads 6a-6h in such a way that they Web rotor can be inserted.
  • inserting the warp threads 6a-6h is in addition to the position of the compartment holding elements 4
  • the position of the stop slats 3a, 3b must be taken into account.
  • Warp threads 6a in the weaving rotor 1 have the advantage that even very densely arranged warp threads are safe insertable between adjacent stop slats 3a, 3b are, or that between two neighboring, with a small distance Stop slats 3a, 3b a warp thread 6a can be safely inserted is.
  • the scope for time increases for inserting the warp threads.
  • the weaving rotor which rotates in the direction of rotation 7, conveys an inserted weft thread 9b to the fabric stop edge 9a, the weft thread 9b being lifted out of the weft insertion channel 4d so that it can be struck against the fabric stop edge 9a of the fabric 6 through the entire stop slats 3a.
  • the weaving rotor which rotates in the direction of rotation 7, conveys an inserted weft thread 9b to the fabric stop edge 9a, the weft thread 9b being lifted out of the weft insertion channel 4d so that it can be struck against the fabric stop edge 9a of the fabric 6 through the entire stop slats 3a.
  • the stop plates 3a, 3b are arranged in the direction of rotation 7 of the weaving rotor 1 in such a way that four successively arranged rows of stop plates 3a, 3b each have a spacing of a / 4 in the direction of the shaft 8, so that after a distance A the stop blades 3a, 3b the stop blades 3a, 3b are again arranged in the same alignment.
  • the distances A1, A2, A3, A4 between the rows of stop slats 3a, 3b are of the same size.
  • the combs 3 with stop lamellae 3a, 3b arranged in succession in the direction of rotation 7 on the surface of the weaving rotor are arranged offset from comb 3 to comb 3 in the direction of the shaft 8.
  • Two whole stop lamellae 3a have a distance a in the direction of the shaft 8. 1c, adjacent combs 3 are each offset in the direction of the shaft 8 by an amount a / 4, so that the stop lamellae 3a, 3b of the fifth comb 3 are again arranged identically to those of the first comb 3, as shown in FIG. 1c are.
  • This offset of the stop slats 3a, 3b, in particular the entire stop slats 3a causes the weft threads 9b to be struck evenly over the width of the fabric 6, so that a uniform fabric 6 is formed. If the stop lamellae 3a were not arranged offset in the direction of the shaft 8, warp streaking could result in the fabric.
  • stop lamellae 3a, 3b can also be arranged offset in the direction of the shaft 8 by an amount other than a / 4, in particular by an integral fraction of a.
