Abstract
An apparatus for controlling a plurality of spinning stations by evaluating yarn signals based upon detection of approximately periodic variations in yarn cross section provides for conversion of the signals to digital form and application of the digital signals to a microcomputer in which the sum of the differences between the original yarn signal and a yarn signal delayed in time is continuously formed. Specific fault signals are produced from the summed differences which are checked against predetermined reference values.
