Claims

[Scope of utility model registration request]

Main nozzle 9 oriented obliquely to the weft direction
This is an air guide device for an air injection loom that performs multicolor weaving using a plurality of main nozzles including b and 9c, and includes recesses 4, 14, 24, and 3 arranged in the weft insertion direction.
4 rows of air guide grooves 8, 18, 28, 38
In the device for guiding the inside of the air guide groove toward the anti-weft entry side while reflecting the jet airflow from each main nozzle by the wall surface of these recesses, the jet airflow Jb from the obliquely oriented main nozzles, In the area where Jc is reflected, for all or part of the wall surfaces 25, 35 in the reflection areas L1, L2, the normal lines H1, H3 erected from these wall surfaces have a lower weft angle than other areas. An air guide device for an air injection type multicolor weaving loom, which changes the inclination of the wall surface so as to face the side.
