Abstract
The winding station of an automatic bobbin winding machine has a splicing device ( ) for the connection of yarn ends following a yarn break. Wet splices are created by the introduction of a liquid. A capacitive sensor ( ) is arranged downstream of the splicing device ( ), by means of which a dielectric change is detected when the moistened yarn passes. The capacitive sensor ( ) is connected with an evaluation unit ( ), which generates a signal when the change falls below a predeterminable threshold value D ( ) because of an insufficient water content. The signal trigger a cleaning cut. The signals are used for monitoring of the yarn quality and monitoring the ability of the splicing device ( ) to function. The invention permits the creation of wet splices of very low moisture content, without causing malfunctions in the winding process or reducing the yarn quality.
