  • Patent number: 6609277
    Abstract: There is put forward a method for texturing thermoplastic yarns with which the thread before the provision of texture is brought to the necessary texturing temperature (T2) and during the actual texturing provision is cooled to a setting temperature (T23). The heating to the texturing temperature (T2) is effected in two steps. The actual texturing line (24) is provided with an active cooling, by which means the yarn is actively cooled to a setting temperature.

  • Patent number: 5873392
    Abstract: A process for automated monitoring of faults occurring in textile webs. At least one marking is worked into the web under manufacture. The marking permits incremental measurement of the textile web and facilitates the determination of particular positions thereon. Web faults and other events are detected during manufacture and their positions stored electronically. Detected faults can then be efficiently located and examined using the electronically stored location coordinates and the marking. Since the marking is worked into the web, the location of the fault can be efficiently determined even at later stages in the manufacturing process.
