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.

Winding station of an automatic bobbin winding machine with a wet splicing device

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

Yarn-connecting device for a cheese-producing textile machine

A method for operating a cheese-producing textile machine which produces cheeses of the &ldquo;random winding&rdquo; type, wherein the contact pressure of the cheese on the yarn guiding cylinder is reduced and the cheese is simultaneously charged with a braking torque for preventing pattern windings. The angular velocity w of the cheese (,) is continuously determined and processed in a control device (,) such that, when or shortly prior to reaching a so-called pattern winding zone (BWZ), the angular velocity w,determined by the diameter d,of the cheese (,) is reduced by means of the definite adjustment of the contact pressure with which the cheese (,) rests on the yarn guiding cylinder (,), to an angular velocity w,which lies below the angular velocity w,of a cheese of the critical diameter d,, driven without slippage, which causes pattern winding.
