Abstract
An air jet nozzle is disclosed which is adapted for imparting entanglements to continuous filament synthetic yarns. The nozzle includes a body member having a yarn passageway therethrough, and a transverse air inlet channel which communicates with the yarn passageway. A yarn threading slot is provided along the length of the yarn passageway for permitting a running yarn to be introduced laterally into the passageway, and a closure plate is mounted so as to be disposed in and substantially close the slot at the periphery of the yarn passageway. The closure plate serves to avoid any disruption of the air currents and thus the entangling process which may otherwise be caused by the presence of the yarn threading slot.
