- Air jet weaving machines are equipped with a large number of air jets: A weft thread wound up as a supply on a storage drum becomes through at least one main nozzle to which compressed air is applied, pulled off and carried into the open shed.
- a weft thread wound up as a supply on a storage drum becomes through at least one main nozzle to which compressed air is applied, pulled off and carried into the open shed.
- Entry frequency and the textile properties of the weft yarn can several main nozzles one after the other as a group of so-called feed and main nozzles between the thread supply and the Shed entrance are arranged, depending on the number of wefts to be inserted double or the front and main nozzles can exist more than once.
- An automatic control ensures that the weft threads in the main nozzles with the optimal air volume can be accelerated.
- the onward transport of the Weft threads through the shed take over relay nozzles, which, in order To save compressed air, be controlled in groups.
- the relay nozzles are fed from one or more compressed air reservoirs, which, in order to reduce compressed air consumption, have different pressure levels.
- At least one stretching nozzle extends the inserted one Weft thread up to the leaf stop.
- blowing and Suction nozzles can be provided to remove faulty weft threads and / or to keep it in a defined position in the weaving area, and / or to Dispose of the cut weft at the shed exit.
- air pressure, air volume and timing for all air jets on the yarn to be processed and on the weaving width be adjusted.

The possibility of the separate compressed air supply unit Positioning largely freely is another big advantage by the Position considering local ergonomic considerations Space can be adjusted.
- Another advantage of the invention is that the separate Arrangement of the compressed air supply unit outside of the rest Loom harmful influences on sensitive components of the Compressed air supply, such as radiant heat in the drive area or Machine vibrations, can be completely eliminated.
- a weft thread 20 comes from a thread spool 21 into a thread store 22, from where it uses compressed air to a pre-nozzle 3 and then transported to a main nozzle 4.
- the actual Weft insertion takes place by means of the pre-nozzle 3 and compressed air Main nozzle 4, with an automatic control, which under the
- the term 'Time Controller' is known to ensure that the weft thread 20 is accelerated at the right time with the optimal amount of air.
- the term 'Time Controller' stems from the fact that the acceleration of the Weft 20 depending on the effectively measured flight time of the Weft 20 is controlled.
- Pre-nozzles 3 and a plurality of main nozzles 4 can be provided to alternately to enter different weft threads 20, which are in Can distinguish color, fineness, texture and material.
- the relay nozzles 5 are made from a compressed air distributor 15 or more compressed air reservoirs 14, which, in order to Reduce compressed air consumption, have different pressure levels can.
- a drawing nozzle 6 ensures that the inserted weft thread 20 remains stretched to the leaf stop.
- blowing and / or Suction nozzles can be provided in order to remove faulty weft threads 20.
- air pressure, air volume and timing for all air nozzles 3, 4, 5, and 6 to the yarns to be processed and to the Weave width can be adjusted.
