ABSTRACT:
A yarn texturing nozzle is disclosed which comprises a rigid yarn feeding inlet portion wherein a yarn is subjected to a heated and pressurized treatment fluid to heat the yarn and also advance the yarn therethrough. The nozzle also includes a stuffer box comprising a thin walled tube which is located downstream of the inlet portion. The inlet portion comprises a block-like casing having a cylindrical bore extending therethrough, and a guide cylinder which is rotatably mounted in the bore and which includes a central yarn passageway. The casing and guide cylinder of the inlet portion include yarn thread-up slots which may be aligned by rotation of the guide cylinder to a thread-up position, and the guide cylinder may then be rotated to an operating position wherein the slots are non-aligned. The stuffer box also includes a thread-up slot which is aligned either with the slot in the casing of the inlet portion, or with the slot of the guide cylinder, and the slot of the stuffer box is adapted to be closed during operation of the nozzle.
