ABSTRACT:
A yarn texturizing nozzle and method of thread-up of the nozzle are disclosed, and wherein the temperature of the nozzle remains substantially unchanged during yarn thread-up. The nozzle includes a body member having a yarn passageway extending therethrough, and the passageway is adapted to be laterally opened to permit the lateral insertion of the yarn during thread-up. Means are provided for supplying a heated treatment fluid such as air to the passageway, and control means are provided for maintaining the mass flow rate of the air substantially the same during yarn thread-up as when the passageway is closed during normal yarn processing.
