In a method for the detection of faults in a length of textile fabric the length of fabric is continuously scanned by means of 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 analysed 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 suchlike are energised as a function of the result of the analysis.
