Abstract
In a method and a device for clearing yarn, properties of the yarn are acquired and used to determine a yarn defect density profile. Yarn defects to be removed are defined by means of an adjustable clearing limit which is based on the density profile. In order to provide an optimum adjustment as frequently as possible, the clearing limit is automatically adjusted on the basis of the acquired properties in a control loop.
