The invention relates to a device for measuring properties of a longitudinally moved test material in a measuring cell. In order to provide a device which is easier to adapt to the requirements of a customer and to the special conditions of a production machine for longitudinally moved test material, the measuring cell ( ) is connected to a processor ( ), which is associated exclusively with the measuring cell.

Device for measuring properties of a longitudinally moved specimen such as yarn

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.
