Method and device for monitoring a yarn tension of a running yarn

Techniques are directed to a method and a device for monitoring a yarn tension of a running yarn in a yarn treatment process. To this end, the yarn tension of the yarn is continuously measured and the measurement signals for the yarn tension are compared with a threshold value of an admissible yarn tension. In the event of an inadmissible tolerance deviation of the measurement signals, a short-term signal path of the yarn tension is detected as a fault graph. In order to enable a fault diagnosis, the fault graph of the yarn tension is analyzed using a machine learning program. The fault graph is then allocated to one of the existing fault categories or to a new fault category. A device for this purpose may include a diagnosis unit, which cooperates accordingly with the yarn tension evaluation unit.

Techniques involve monitoring a texturing process for producing crimped threads. A thread tension is measured continuously on the textured thread and the measured signals of the thread tension are detected and analyzed continuously, at least in one time interval. For the early diagnosis of one of multiple sources of faults, a sequence of the measured signals occurring in the time interval is analyzed by means of a machine learning program. To this end, a device for monitoring has a diagnostic unit, which interacts with the thread tension measuring device in such a way that the measured signals of the thread tension can be analyzed by means of a machine learning program in order to identify one of multiple sources of faults.

Modular festoon system

In one example, a festoon system comprises a festoon module having a support assembly, and further comprises at least one upper sheave and at least one lower sheave, which are movable relative to one another by movement of at least one of the upper sheave or the lower sheave. At least one wire is configured to enter the festoon module at an entrance region, extend around a groove of the least one lower sheave and at least one groove of the at least one upper sheave, and then exit the festoon module at an exit region. A first coupling location of the support assembly is adjacent to the entrance region of the festoon module, and a second coupling location of the support assembly is adjacent to the exit region of the festoon module. Different modules are configured to be coupled to the second coupling location.

During normal operation of a textile machine, a fiber bundle is supplied to a consolidating means to produce a roving having a protective twist, the roving wound onto a tube with a winding device. The roving downstream of the consolidating means is monitored for whether the roving is being produced by the consolidating means or whether the roving produced by the consolidating means is being wound onto the tube. In no roving is being produced or the roving produced by the consolidating means is not being wound onto the tube, an interruption of the normal operation of the textile machine is initiated and the tube partly loaded with roving by the winding device prior to the interruption is replaced with an empty tube during a tube changing process. The consolidating means is started up and the roving produced thereby is brought into contact with the empty tube. Normal operation is resumed and the roving is wound onto the empty tube.

Bobbin carrier for a braiding, winding or spiraling machine

The invention relates to a bobbin carrier for receiving a bobbin which is set up for unwinding a strand material, wherein the bobbin carrier is provided for use in a braiding, winding or spiraling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier has a tensile-force measuring device for measuring the tensile force of the strand material unwound from the bobbin and has a first data transfer device for transferring data. According to the invention, the first data transfer device is set up to transfer measured tensile force values to a second data transfer device arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material can be detected early at the individual bobbin carriers. The tensile force can be kept largely constant by the transfer of set point tensile force values from the second data transfer device to the first data transfer device and by a suitable control or regulation device at the bobbin carrier.
