Abstract
A yarn texturing apparatus which comprises a nozzle having a passageway through which the yarn is advanced, and a duct system for introducing heated air into the passageway. A perforated stuffer box is disposed adjacent the outlet end of the passageway. The duct system for the heated air includes an annular duct surrounding the passageway, and a supply duct communicating with the annular duct. Also, an adjustable deflector is mounted in the supply duct immediately adjacent the annular duct for imparting a circumferential component to the heated air as it enters the annular duct, and which in turn imparts a slight twist to the advancing yarn so as to facilitate its smooth advance.
Claims18
An apparatus for texturing an advancing yarn with a pressurized heating fluid and comprising:
- a nozzle including a passageway through which the yarn is to advance at high speed from an inlet end to an outlet end of said passageway;
- duct means for conducting a pressurized heating fluid into said passageway during operation of said apparatus, and including an annular duct surrounding said yarn passageway in said nozzle, a supply duct communicating with said annular duct, and a conical duct extending from said annular duct to said yarn passageway;
- a perforated stuffer box disposed adjacent the outlet end of said yarn passageway for receiving and forming a compressed plug from the advancing yarn exiting from said passageway;
- and
- means mounted in said supply duct for adjustably controlling the direction of flow of the heating fluid into said annular duct.
