Abstract
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.
