A yarn producing apparatus produces carbon nanotube (CNT) yarn by aggregating CNT fibers, A substrate support supports a CNT forming substrate, a winding unit continuously draws the CNT fibers, a yarn producing unit aggregates the CNT fibers, a status monitor monitors a state of the CNT yarn, and a supply state changing mechanism changes a supply state of the CNT fibers, based on a result of monitoring by the status monitor.

A method is provided for operating a textile machine having a plurality of work stations wherein, during normal operation of the work stations, a yarn is produced or is rewound from a delivery coil onto a receiver coil. The normal operation is initiated at the individual work stations after a stop of the textile machine, or is interrupted at certain time intervals by a service operation in the form of a piecing process, a tube changing process, or a yarn joining process. The service operations are divided into several partial sequences. A pending partial sequence for one of the service operations is carried out so long as energy resources required for carrying out the pending partial sequence are available independent of whether the energy resources for carrying out the other partial sequences for the service operation are available.

An intelligent yarn loading system and a control method are provided. The intelligent yarn loading system comprises a twisting machine, a self-walking trolley and a dispatching control system; the twisting machine is provided with a twisting machine wireless communication module for sending a working state of the twisting machine to the dispatching control system; the self-walking trolley is provided with a trolley wireless controller and a self-walking device for receiving an instruction of the dispatching control system and walking to a station of the twisting machine to take off an empty bobbin, and put a basic yarn on a creel of the twisting machine or take off a finished product package for stacking.

The present invention is a part of a yarn transfer system used for transferring yarn from a full bobbin to an empty bobbin typically fitted on a winder frame. The invention broadly comprises a yarn traverse device used in transferring a continuously arriving yarn onto an empty bobbin for commencing of winding process during bobbin changeover process in automatic turret winder without any stoppage. This is achieved with the provision of an actuation device that facilitates axial movement of the yarn traverse device. In the present invention, during the bobbin changeover operation, the yarn traverse device is moved axially through the actuation device and allows the traverse guidewhile maintaining its normal traverse speed at all timesto move beyond the normal yarn winding zone such that the advancing yarn is within the reach of the yarn grasping device of the ready-to-be-wound empty bobbin. After the yarn transfer is completed, the traverse device moves back to the normal winding zone.
