ABSTRACT:
A main nozzle for an air jet loom has an outer casing and is provided with a compressed air introduction duct and a mixing chamber. A mixer tube provided with an annular distributor ring is inserted into the outer casing to form with the outer casing and annular distribution chamber upstream of the distributor ring and, downstream of the distributor ring, and annular accceleration chamber which feeds into the mixing chamber. The distributor ring has annularly arranged blowing slots. The acceleration chamber is formed by an outer conical wall provided on a portion of the inside of the outer casing and an inner conical wall provided on a portion of the mixing tube. The tapered walls of the annular acceleration chamber optimize the air jet used for inserting the weft into the shed. The inclination of the taper of the outer wall of the nozzle annular acceleration chamber is 12.degree.-16.degree., and that of the inner wall is 4.degree.-8.degree.. In the preferred embodiment, the taper of the outer wall is 15.degree. and that of the inner wall is 7.degree..
