Abstract: An apparatus for the automatic adjustment of a yarn cleaner at a winding machine, such yarn cleaner embodying at least one measuring cell, an amplifier and a pulse shaper. A signal feedback circuit electrically couples the output of the pulse shaper with the input of a control device which by means of its output signal brings about the adjustment of the amplification gain at the aforementioned amplifier. The signal feedback circuit embodies a pulse evaluation circuit which serves to generate an average value signal from a predetermined number of signals appearing at the output side of the pulse shaper.
