ABSTRACT:
A weft ejection nozzle for water jet looms is provided with a flow controller incorporated therein while embracing the nozzle main body in such an arrangement that the operating fluid from a given supply source is rendered to flow, in the first place, centripetally towards the periphery of the nozzle main body, to flow, in the second place, axially along the periphery of the nozzle main body, both being in the form of several flows separated from each other and being free of mutual interference, and to flow, finally, collectively and convergingly towards the weft ejection terminal of the nozzle, whereby the flow of fluid is so rectified as to entrain the weft for insertion into open sheds with increased propelling force.
