Definitions

  • the invention relates to a stationary thread guide element according to the The preamble of claim 1.
  • the invention further relates to a Row shed weaving machine comprising a stationary thread guide element according to the preamble of claim 8.
  • a weft distributing device is known from the publication EP 0 433 216 B1 a row shed loom with air intake is known.
  • Such one Row shed weaving machine includes one rotatable about an axis of rotation mounted rotor, on the surface of which a plurality of Weft insertion channels in the direction of the axis of rotation and in Are circumferentially regularly spaced to simultaneously a plurality of weft threads, in particular four weft threads in the Enter the web rotor.
  • the weft distributing device comprises a stationary one Thread guiding element and one that rotates with the weaving rotor Thread guiding element.
  • the known row shed weaving machine is used two circular thread guide elements, one stationary and one co-rotating thread guide element, which are formed from metal, and which have a plurality of grooves on the end faces through which the weft is guided.
  • the two end faces lie during this Operation either on each other, resulting in mutual wear and tear leads, or they are arranged so that between the two End faces form an air gap, with very thin yarns in these Penetrate air gap, which leads to an incorrect entry.
  • Another disadvantage is that The fact that during the operation of the series shed loom Dirt accumulates between the end faces, reducing the mutual distance of the two end faces increased and the likelihood of additional Incorrect entries increased.
  • the object of the present invention is an economically more advantageous one Propose thread guide element.
  • the task is solved in particular with a stationary Thread guide element for a row shed weaving machine, which on a Front side has a plurality of concentrically extending grooves, wherein the thread guide element as a circular segment or as a circular sector is designed.
  • An advantage of the stationary thread guide element according to the invention is the fact that the thread guide element as a circle segment or as Circular sector is configured, and for example over a Angular range between 30 degrees and 180 degrees and preferably over 120 Degrees extends. On the one hand, this causes mutual wear of stationary and co-rotating thread guide element reduced, because of their the two faces no longer lie completely on top of each other, but only still along that formed by the stationary thread guide element Face.
  • Another advantage is the fact that the accumulation of Dirt between the two mutually touching end faces is reduced because the end face of the rotor is no longer covered continuously, so that the dirt either falls off by itself, or with, for example Support of additional fluid nozzles directed towards the end face, Will get removed.
  • the stationary one Thread guide element over an angular range of 120 °.
  • the stationary Thread guide element is thus very inexpensive to manufacture, in which a first manufacturing step, a circular body containing three Thread guide elements is processed, which in a subsequent Process step is divided into three parts of equal size, so that three stationary thread guide elements arise, each one Thread guide element extends essentially over 120 °.

In the illustrated embodiment, the stationary one Thread guide element 1 approximately in the circumferential direction of the holding means 3a 120 °, with the stationary thread guide element 1 on one side a narrow end, adjacent to the stationary transfer part 3c is arranged.
  • Fig. 2 shows a side view of the row shed weaving machine during the Business.
  • a weft thread 4a is passed through the fluid nozzle 3d
  • Weft feed channel 3b supplied passes through the stationary Transfer part 3c in the stationary thread guide element 1, is in it deflected, and on the rotatable thread guide element 2a and that Thread guide element 2e fed to a weft insertion channel 2c.
  • the stationary thread guide element 1 is in the direction of rotation 2f slidably supported by the guide means 3e and is by the in Direction of rotation of the axis of rotation 2f acting springs 3f to the front of the rotatable thread guide element 2a pressed.
  • the stationary Thread guide element 1 is slidably mounted in the direction of movement 1h. In the view according to FIG.
  • the stationary thread guide element 1 is in a left-hand stop position shown on the holding means 3a.
  • the stationary means can be set by means not shown Thread guide element together with the holding means 3a even further shift to the left, thereby the thread guide channels 1a, 1b, 1c, 1d to expose and make accessible, for example in the event of faults such as a weft break.
  • the stationary thread guide element 1 can 1h in the direction of displacement be moved and the end face of the rotatable thread guide element 2a are supplied.
  • Fig. 4 shows a perspective view of a section of another Embodiment of a stationary thread guide element 1, which has four grooves 1a, 1b, 1c, 1d spaced apart in the radial direction and slidably mounted in the direction 1h with respect to the fixed part 3 is.
