Field of the Invention The present invention relates to a method and a system for injection in a double nozzle type air jet room, and more particularly to an upstream side in a double nozzle type air jet room in which two main nozzles are cascaded in a weft insertion direction. The present invention relates to an injection control technique for a side main nozzle.

きる。2. Description of the Related Art A loom using a double nozzle as described above is disclosed in Japanese Patent Publication No. 61-37376. In the case of this prior art, the low-pressure injection force from each of the upstream and downstream main nozzles can be made smaller than that when one main nozzle is used. Can be reduced.

射をオフにして糸通しし易いようにしている。In the technique disclosed in Japanese Patent Application Laid-Open No. Hei 1-213436, a traction nozzle is provided upstream of a main nozzle so that low-pressure injection is always performed. When threading the main nozzle, the low pressure injection of the traction nozzle is always turned off to facilitate threading.

噴射によって経糸開口中に吹き込まれ易いのである。However, in any of the above-mentioned prior arts, the fly waste floating around due to the constant low-pressure injection from the main nozzle arranged on the upstream side is in the main nozzle arranged on the downstream side. There is a problem that it is blown into the warp shedding and becomes entangled with the weft or the warp, thereby deteriorating the quality of the fabric. In addition, fly waste adhering and depositing on the downstream main nozzle is easily blown into the warp shedding by the constantly low-pressure injection from the upstream main nozzle.

ることにある。In the case of the main nozzle on the further upstream side,
Since low-pressure injection is most often required during threading, it is not preferable to always perform low-pressure injection at other times from the viewpoint of energy saving. SUMMARY OF THE INVENTION It is an object of the present invention to prevent a decrease in fabric quality and waste of energy due to low-pressure injection by an upstream main nozzle in a double nozzle type air jet room.

Connected to the pressure source PS. The normal weft insertion pipe line has a regulator 31, a tank 33, and a specific on-off valve 32 shared with the first main nozzle N1. The low-pressure pipe line for threading has a regulator 11 and an on-off valve 12 which is opened only when threading. On-off valve 12
It is opened only during threading while the loom is stopped, based on the operation of a command switch (not shown). A check valve for preventing the backflow of the high-pressure fluid from the weft insertion pipe line is provided in each of the low-pressure injection, threading and cutting blow pipe lines.

ギーもそれだけ節減される。In the upstream main nozzle, low-pressure injection is performed at the time of threading, so that the threading operation itself can be performed without any trouble as in the case of the conventional double nozzle type air jet room. However, since the low-pressure injection is not performed in other periods, fly waste is not blown into the main nozzle and the warp shed on the downstream side, and the energy is saved accordingly.
