A method and apparatus for removing fluid and cooling the wad of textured yarn on the barrier screen of a moving cavity texturing jet by deflecting the hot fluid (such as steam) away from the underside of the screen with rotating turbine blades and by drawing ambient air across the screen with a vacuum line under the screen has been discovered.

Yarn texturing by moving cavity jet with fluid removal

Apparatus and method are disclosed to prevent melted yarn when stopped in a high temperature texturing jet device utilizing high temperature fluid such as steam. The device of this invention is attached to the prior art texturing jet device. The attachment comprises a sleeve around the yarn ejector. The sleeve has at least two orifices communicating with a conduit for high pressure fluid having a valve actuated by a sensor to detect yarn stoppage. The high pressure fluid, such as air, blows the yarn plug and yarn from the texturing jet device. The method comprises sensing yarn stoppage with a sensor and actuating the valve in the high pressure fluid conduit communicating with at least two orifices in the sleeve surrounding at least the down stream portion of the injector and blowing any yarn in the texturing chamber out of the chamber with high pressure fluid.

Method and apparatus to blow yarn and plug from high temperature yarn

An improved process and apparatus for production of synthetic multifilamentary yarns having uniform quality. The method comprises extruding a molten synthetic polymer downwardly through a spinneret, advancing the extruded filaments downwardly through a substantially stationary column of heated air, and subsequently advancing the filaments downwardly through a quenching zone wherein they are in contact with cooling air introduced into the path of the filaments under controlled conditions of air velocity and direction of flow. The apparatus for carrying out the process comprises an extrusion spinneret for extruding a number of filaments directly into a heated sleeve having walls that are imperforate, said heated sleeve leading to a quenching chamber having opposite, essentially vertical inlet and outlet panels for allowing cooling air to pass through the chamber, and means for regulating the stream of cooling air whereby both the velocity of the air stream going through the quenching chamber and its general direction as it contacts the descending filaments may be regulated.
