Resumen:
Una universidad alemana de ciencias aplicadas ha desarrollado un método óptico para monitorizar la velocidad y longitud de un hilo común durante el proceso de producción textil. El uso de un método de medición óptica ofrece una alta precisión sin tensión y sin dañar el hilo. Un haz láser se divide en dos haces paralelos. Ambos haces atraviesan un volumen de medida, que también es atravesado por el hilo. Solo el primer haz se dirige al hilo, mientras que el segundo sirve de referencia. Debido a la dispersión producida por el hilo en las ondas esféricas, se produce una señal Doppler. Esta señal se mide con un detector óptico del primer haz, de manera que puede medirse la velocidad y longitud del hilo. Se trata de un método asequible y fácil de mantener. La universidad ofrece licencias a empresas de la industria textil o la posibilidad de establecer acuerdos de cooperación técnica para promover la tecnología.

Method to measure speed and length of a running thread in textile production processes
Summary:
A German university of applied sciences developed an optical method that monitors the speed and length of a running yarn during the ongoin production process. The use of an optical measuring method offers high precision without stressing or even damaging the thread. This method is inexpensive and easy to maintain. The university offers licenses to companies active in the textile industry or the possibility of a technical cooperation in order to advance the technology.
Description:
A German university of applied sciences developed a non-contact measuring method with which the speed and the length of a running thread can be measured. For this purpose, a laser beam is split by prism optics into two parallel beams. Both beams pass through a measurement volume, which will also be passed through by the thread. Only the first beam is directed to the thread, the second beam serves as a reference. Due to the scattering resulting from the thread on the spherical waves, a Doppler signal arises. This signal is measured by means of an optical detector of the first beam. In this way the speed and length of the running yarn can be measured. Furthermore, by reducing the intensity of the first beam by the thread, it is possible to determine the thickness of the yarn.

Due to the use of an optical measuring method velocity and length can be measured with high precision, without stressing the thread itself or even damaging it. The measurement is carried out continuously and it is inexpensive and easy to maintain.

The invention finds particular application in the textile industry for the monitoring of ongoing production processes. Running processes can be accurately monitored with this technology while at the same time waste and defects in the production can be significantly reduced.

The University offers companies active in the textile industry the possibility of licensing the technology or a technical cooperation in order to advance/adapt the technology.
