Definitions

  • the invention relates to a weaving rotor with stop blades according to the preamble of claim 1.
  • the course of the axis of rotation of the weaving rotor has a relatively small distance, so that it is difficult to securely insert a warp thread guided by laying elements between two adjacent stop lamellae.
  • a warp thread density there is a risk that the individual warp threads are incorrectly inserted into the interstices of the stop slats, which leads to warp streaking or to a weakening of the binding.
  • the invention has for its object to provide a weaving rotor that overcomes the disadvantages mentioned.
  • Subclaims 2 to 4 relate to further advantageous embodiments of the invention.
  • One advantage of the invention is that the distance between two stop slats can be increased in the direction of the axis of rotation of the weaving rotor, so that a warp thread can be inserted between the two stop slats with increased reliability.
  • Another advantage can be seen in the fact that the stop lamellae, which are arranged offset in the direction of rotation of the weaving rotor, strike the weft threads evenly against a fabric stop edge.
  • Fig. La is a top view of a weaving rotor
  • Fig. Lb is a side view of the weaving rotor
  • Fig. Lc another top view of the weaving rotor.
  • FIG. 1b shows a cylindrical weaving rotor 1, on the surface of which shed-forming shed holding elements 4 are arranged, which bring the warp threads 6a, 6b-6h running in the direction of rotation 7 of the weaving rotor 1 into a high shed position or a down shed position, so that a weft insertion channel 4d is created, through which a weft thread can be inserted using a fluid such as air.
  • a weft insertion channel 4d runs parallel to the shaft 8 of the weaving rotor 1 and extends over the entire width of the weaving rotor.
  • Direction of rotation 7 are alternately arranged on the surface of the weaving rotor 1, shed retaining elements 4 and stop plates 3a, 3b.
  • the stop slats are designed as whole stop slats 3a or as half stop slats 3b. The whole
  • Stop slats 3a are designed such that they If the weft thread 9b is completely inserted between the warp threads 6a-6h and is located immediately in front of the fabric stop edge 6a, the weft thread 9a is struck.
  • FIG. 1 a shows a top view of the surface of the cylindrical weaving rotor 1.
  • Shed holding elements 4 are arranged on the weaving rotor 1, which have projecting parts 4a, 4b and form a saddle surface 4c in between.
  • the warp threads 6a-6h are placed on the surface of the weaving rotor 1 in such a way that a warp thread 6a-6h either runs over a saddle surface 4c, a compartment holding element 4, so that the warp thread assumes a high position, or in such a way that a warp thread 6a-6h between two compartment holding elements 4 runs and occupies a low position.
  • a shed is thus formed through which a weft thread can be inserted.
  • Laying elements 5a-5h which are movable parallel to the shaft 8 of the weaving rotor 1, are used to insert the warp threads 6a-6h into the weaving rotor and position the warp threads 6a-6h in such a way that they are inserted into the weaving rotor.
  • the position of the stop slats 3a, 3b must also be taken into account.
  • the alternating arrangement of half and full stop slats 3a, 3b in the direction of the shaft 8 can be used advantageously for the insertion process by initially positioning a warp thread 6a by the laying element 5a in such a way that the warp thread 6a is securely closed between two whole stop slats 3a comes to lie.
  • the laying element 5a can be moved again to determine in which of the two through the half stop slat 3b arranged between the whole stop slats 3a trained spaces between the warp thread 6a is to be inserted.
  • the freedom of movement of the warp thread 6a is limited by the entire stop plate 3a, whereas the half stop plate 3b does not yet hinder the freedom of movement of the warp thread 6a.
  • the laying element 5a can thus be deflected such that the warp thread 6a lies against the entire stop lamella 3a, so that the warp thread 6a is securely inserted between the two stop lamellae 3a, 3b.
  • Such a method for inserting warp threads 6a into the weaving rotor 1 has the advantage that warp threads arranged in a very close manner can also be securely inserted between adjacent stop slats 3a, 3b, or that between two adjacent ones with a small distance
  • Stop slats 3a, 3b a warp thread 6a can be safely inserted. At the same time, this increases the time for inserting the warp threads.
  • the weaving rotor rotating in the direction of rotation 7 conveys an inserted weft thread 9b
  • 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 slats 3a, 3b the stop slats 3a, 3b are again arranged in the same alignment.
  • the distances AI, A2, A3, A4 between the rows of stop blades 3a, 3b are of the same size.
  • the successively in the direction of rotation 7 on the Combs 3 arranged on the surface of the weaving rotor with stop lamellae 3a, 3b are arranged offset from comb 3 to comb 3 in the direction of the shaft 8.
  • Two entire stop lamellae 3a have a distance a in the direction of the shaft 8. In the direction of rotation 7 adjacent combs 3 are, as shown in Fig.
  • Stop slats 3a not arranged offset in the direction of the shaft 8, so a warp streak could arise in the fabric. Without a staggered arrangement of a quarter of the distance a, four times as many stop slats 3a, 3b would have to be arranged per arranged row of stop slats 3a, 3b in order to achieve approximately the same quality of a weft thread on the fabric stop edge.
  • the stop plates 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.

Abstract

L'invention concerne le rotor (1) d'un métier à tisser avec ouverture des fils en série, qui présente des lamelles de butée (3a, 3b) disposées à la surface et orientées dans le sens de rotation (7). Le rotor (1) présente un arbre (8), et les lamelles de butée (3a, 3b) qui se succèdent dans le sens de rotation (7) sont disposées de manière à être décalées dans le sens de rotation de l'axe (8).
