  • the texturing process is submitted to partially stretched spun synthetic threads.
  • each thread is individually textured within a texturing zone and simultaneously stretched.
  • the threads preferably receive a false twist, which is fixed in the texturing zone by means of a heating device and a cooling device. After leaving the texturing zone, the so crimped yarn is wound up into a bobbin.
  • the thread tension of the guided in the texturing zone thread has proven.
  • This is in the known method for quality monitoring, continuously measuring a yarn tension within the texturing zone on the already crimped yarn.
  • the thread tension is monitored for its uniformity.
  • the known device for texturing has for this purpose a yarn tension sensor which is arranged between a texturing unit and a second delivery roller.
  • mechanical means are used, which require an additional thread deflection in the yarn path. In principle, however, any mechanical intervention on the thread to produce a uniform crimping of the filaments within the thread to avoid.
  • alternative methods and devices are known in which the thread tension is monitored by the drives of the delivery rollers.
  • This method thus requires a variety of quality parameters to monitor a texturing process.

  • Another object of the invention is to provide a generic method for quality monitoring during texturing and a generic device for texturing, in which both the stretching and the texturing of the thread can be monitored.
  • This object is achieved by a method for monitoring the quality of texturing a synthetic thread with the features of claim 1 and by a device for texturing a synthetic thread with the features of claim 10.
  • the invention is based on the recognition that the delivery roller arranged on the outlet side of the texturing zone has a significant influence on the overall texturing process.

  • a limit value or a limit value range of the operating torque can be stored, which corresponds to a desired thread quality if it is adhered to.
  • the overshoots or undershoots can be differently evaluated by the actual value of the operating torque.
  • a difference value of the operating torque between the actual value and the relevant limit value is determined and a signal generation and / or a process change is initiated as a function of the size of the difference value. Absolute value differences can thus be used directly for process control.
  • a time duration of the overshoot or undershoot is determined when the limit value and / or limit range is exceeded or undershot, wherein the time duration is compared with a limit duration, and when the limit duration is reached a signal generation and / or a process change initiated becomes.

  • Another alternative method variant is often used to make a quality rating of the yarn produced.
  • the overshoot or undershoot of the limit value or limit value range can be detected by an actual value as a disturbance event.
  • the disturbance events are added up to a number of disturbances, whereby signal generation and / or a process change is initiated when a marginal disturbance number is reached.
  • This variant of the method can also be used preferably to define maintenance cycles on the units.
  • the process variant is preferably carried out, in which prior to a process start the supply roller is driven by the electric motor without thread, in which an idle actual value of the operating torque is detected and in which the idle actual value of the operating torque with a predetermined idle setpoint of Operating torque is compared.

  • the stored reference set point of the operating torque can then be used to be converted with a stored tolerance value and / or tolerance value range to the limit value and / or limit value range of the operating torque. This ensures that possible disruptive parameters such as bearing friction or air resistance at the delivery roller can be neutralized.
