Abstract: 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.

Abstract: A yarn-connecting device for a cheese-producing textile machine having a pneumatic splicing device (22) located outside of the normal travel path of the yarn, a gripper tube (25) acted upon by suction air for manipulating yarn ends to be spliced, and a pivotable gripper tube flap (18) for closing the gripper tube mouth (27). A control crank (33) is arranged at an upper end position (II) of the gripper tube (25) for acting on the gripper tube flap (18) such that in the course of pivoting the gripper tube (25) into the position (II), the gripper tube flap (18) is lifted slightly off the gripper tube mouth (27), while the gripper tube flap (18) always closes the gripper tube mouth (27) when the gripper tube (25) is pivoted out of the position (II).
