ABSTRACT:
An improved air nozzle for processing a fiber bundle such as a staple fiber roving or a multifilament yarn. The air nozzle comprises a narrow channel and a wide channel in series, and part of the narrow channel protrudes into the inside of the wide channel so that a double tube is formed in the connecting portion thereof. Further, at least one jet is provided in the wide channel in the vicinity of the protruding end of the narrow channel. Due to this construction, no turbulence occurs in the wide channel during operation and an excellent sucking effect, as well as an excellent twisting effect, is obtained.
