ABSTRACT:
A yarn cleaner for cleaning defects from a yarn, by means of a head for measuring at least one yarn parameter for comparison against cleaning limits determined for the yarn parameter. If the cleaning limits are exceeded, a defect in the yarn is indicated whereby intolerable defects may be cut out from the yarn. The yarn cleaner is set up for cleaning an effect yarn, also called a novelty or fancy yarn, formed from an alternating thinner webs and thickened effects in the yarn. At least one value of the yarn parameter is predetermined for webs and for effects and the cleaning limits of the yarn cleaner are adjusted such that they lie outside the predetermined value of the web parameter and outside the predetermined value of the effect parameter.
