摘要： A yarn texturizing nozzle is disclosed which has two confronting sections that are separable along a separating plane projecting through and longitudinally of a yarn duct that extends through the nozzle and that is supplied with a pressurized fluid such as hot air. A piston within a cavity of one of the nozzle sections is biased by the pressure of fluid within such cavity into abutting engagement with the confronting surface of the other of the nozzle sections. The piston is so designed as to deform, under the force of such engagement, sufficiently as to conform to any unevenness of the confronting surface of the other nozzle section, and so as to minimize fluid leakage at the interface of the nozzle sections.

摘要： A yarn texturing nozzle is disclosed which comprises a 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 located downstream of the inlet portion. The inlet portion comprises a rectangular block which is divided into two parts along a plane extending coaxially through the yarn passageway to facilitate yarn threadup, and the stuffer box includes a slot through the side wall thereof which further facilitates yarn threadup.
