  • Patent number: 8468791
    Abstract: A texturing machine is described comprising a plurality of processing points for texturing a plurality of multifilament threads. The texturing machine comprises a plurality of delivery mechanisms per processing point and a texturing system for guiding, drawing and texturing one of the threads. A central heating device is associated with the processing points for thermal treatment of a plurality of threads, wherein the texturing systems within the processing points downstream of the heating device each delimit a texturing distance. In order to treat all threads qualitatively the same, according to the invention the texturing systems of the processing points associated with a thread outlet of the heating device are held in a symmetrical arrangement with respect to the heating device such that the threads within the processing points can be guided in texturing distances of the same length.

  • Patent number: 6799414
    Abstract: A texturing machine for producing a crimped yarn and which has a plurality of serially arranged yarn processing units leading to a takeup device. A threading device is provided for threading a yarn for the first time before the start of a process. For this purpose, the threading device comprises at least one guide tube and an air injector connected thereto, with the guide tube including a suction inlet for receiving the yarn. In accordance with the invention, a cutting device is arranged in the region of the suction inlet of the guide tube, with the cutting device cutting the yarn while being threaded into the suction inlet.
