Estimating the term…
The winding station of an automatic bobbin winding machine has a splicing device (7) for the connection of yarn ends following a yarn break. Wet splices are created by the introduction of a liquid. A capacitive sensor (13) is arranged downstream of the splicing device (7), by means of which a dielectric change is detected when the moistened yarn passes. The capacitive sensor (13) is connected with an evaluation unit (12), which generates a signal when the change falls below a predeterminable threshold value DSW (32) 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 (7) 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.
A winding station of an automatic bobbin winding machine, comprising a splicing device for connecting yarn ends after a yarn break, means associated with the splicing device for introducing a liquid into a spliced connection of yarn ends, a capacitive sensor arranged downstream of the splicing device for detecting a dielectric change representing the liquid in the spliced connection, and an evaluation device connected with the capacitive sensor and adapted to generate a signal when a detected dielectric change fails to satisfy a preselectable value.
