More specifically, the present invention relates to a deformed reed for stably operating a high-speed air jet loom having a loom speed of more than 600 rpm.

い。2. Description of the Related Art Conventionally, most of the rotation speed of an air jet loom with an auxiliary nozzle is 500 to 600 rpm.
However, recently, a higher speed type has been developed and put into practical use. However, when the speed is increased, the weft flying becomes unstable, and when the number of revolutions of the loom is 900 rpm or more, the number of loom stops is often more than 10 times / unit / day.

とができていないのが現状である。The loom rotation speed is 500 to 600 rpm.
However, the number of loom stops is 5 to 8 times per machine / day, which is not always stable. Most of the stops are caused by the entanglement of the weft thread called tangle, which does not reach the fabric end on the non-nozzle side. As an attempt to reduce this entanglement stop, research on the specifications of the main nozzles, sub-nozzles, air injection conditions, specifications of deformed reeds, etc. has been made so far, and various studies have been made on the specifications of deformed reeds. The current situation is that we have not been able to reduce the number of entanglement stops.

It is a modified reed for high-speed air jet loom, which is characterized by The modified reed for a high-speed air jet loom according to the present invention is, as shown in FIG. 1, a main nozzle side main wing 1, a cutter space 2, a decorative wing 3, a flat reed wing 4, a modified reed wing 5, an anti-nozzle side main wing.

It is 5 mm or less. If the array width exceeds 3 mm, the distance from the tip of the main nozzle to the deformed reed wing becomes long, so the diffused airflow of the jet air from the main nozzle collides with the upper and lower jaws of the deformed reed wing and the airflow is disturbed. Simultaneously with the generation of the weft yarn, the leading end portion of the weft yarn is also guided by this diffused air flow and collides with the upper jaw portion and the lower jaw portion of the deformed reed wing as well, so that the weft conveyance failure easily occurs. Further, when the arrangement width is 1.5 mm or less, it is less likely to be affected by the diffused air flow of the main nozzle jet air, and the weft flying is stabilized.

Reach The deformed reed for a high-speed air jet loom of the present invention requires that the void ratio of the modified reed arranged between the flat reeds 4 and 20 mm immediately after the flat reeds 4 is 40 to 55%. The function of converging the diffused airflow of the main nozzle jet air, which develops in the above, is deteriorated and the flight of the weft becomes unstable. On the other hand, if it is less than 40%, the space for inserting the warp becomes narrow and the warp cutting is likely to occur.

Porosity (%) of modified reed wing = ab−a × 100 a: Arrangement width (mm) of modified reed wing b: Total thickness (mm) of modified reed wing arranged in a (mm) The porosity, as a result of intensive studies by the present inventors,
The tip entanglement stop causes flight failure immediately after the weft starts to fly, leading the tip of the weft injected from the main nozzle into the deformed reed groove while maintaining a stable posture, and 30 mm from the main nozzle.
It was clarified that it is most effective to keep the flow velocity distribution within the range stable for the tip entanglement stop reduction.
