A handheld yarn measuring device () for monitoring yarn in yarn processing machines. The yarn measuring device includes a catcher (), which when a trip lever () is actuated, places the yarn over a yarn applicator element () of a force sensor (). The yarn tension and speed is detectable and delivered to a processing device for display and further processing. The device, which may be operated by one hand, has a boomerang-shaped housing () one end of which supports the trip lever (), a control knob () and a display (). The control knob () can be twisted and depressed by the user's thumb so that the selection of all the measurement and operating modes can be done with only the thumb. The measurement is performed by means of the trip lever (), which actuates both the yarn catcher () and a measurement activation switch ().

In a method and system for the detection of faults in a length of textile fabric, the length of fabric is continuously scanned by an electro-optical sensor head. Light detectors located in a strip-form sensing zone of the sensor head are assembled in groups and emit group-specific fault signals. These fault signals are analyzed multi-dimensionally for the identification of spot faults and/or long faults, the criteria for analysis being the signal amplitude, the signal length, the recurrence of the signals and their periodic repeat at each revolution of the machine. Display, control counter devices and the like are energized as a function of the result of the analysis.
