AUTOMATED YARN PACKAGE HANDLING SYSTEM AND METHOD
An apparatus and method of automatically moving yarn packages between yarn processing stations in a textile environment that includes the steps of providing a yarn package elevator, transporting a yarn package on the yarn package elevator from a textile machine position to a common transfer location, and holding the package in a stationary position on an elevator tray. A label is applied to a surface of the package and the elevator tray and package is moved to a knot-tying location, the package is removed from the elevator tray to a knotting head apparatus at the knot-tying location and a knot is tied in a package yarn tail of the package to secure the package tail from unraveling in subsequent package handling steps. Correct application of the knot to the yarn tail is either validated, or in the alternative, if the knot is not validated, the package is forwarded to a location for manual reworking to apply a correct knot to the yarn tail.
Method for monitoring air flows required for handling a thread and/or fiber band and spinning machine unit
A method for monitoring air flows required for handling a thread and/or fiber band in a spinning machine, and to a spinning machine unit. At least one air flow-generating source is connected to an air flow duct. An air volume flow measuring unit is connected to an evaluation device for data transmission. The air volume flow is measured by the air volume flow measuring unit and the measurement result is transmitted to the evaluation device. The number of productive and/or non-productive spinning positions is detected. An air volume flow target value is determined by the evaluation device. The air volume flow target value is compared with actual value of the measured air volume flow by the evaluation device, the evaluation device making an evaluation on the basis of the comparison as to whether there is an unacceptable deviation between the actual value and the air volume flow target value.

Ring spinning system and method for operating
A method to operate a ring spinning system containing a ring spinning machine having spinning positions and a winding machine having winding positions. Yarn is spun at the spinning position and wound to a cop. Values of a spinning parameter are determined at different times during the winding of the cop and stored as spinning data. The cop is transported from the spinning position to the winding position, where the yarn is rewound from the cop onto a bobbin. Values of a yarn parameter are determined at at least two different times during the rewinding, and stored as yarn data. The spinning data and the yarn data are assigned to each other such that they relate to the same yarn section. Based on the spinning data and yarn data assigned, an intervention is made on the ring spinning machine.
