Abstract
The present invention relates to a loom control system operable to stop a loom in the presence of a yarn breakage. This loom comprises a feeding device having a yarn storage drum for temporarily storing the yarn and a yarn store sensor for sensing the quantity of yarn stored on the drum of the feeding device and for transmitting an electric sensor signal representing the quantity of yarn stored on the drum to the feeding device to control the operation of the feeding device and to thereby control the quantity of yarn stored on the drum. A monitor circuit is electrically connected to the yarn store sensor for receiving the sensor signal, wherein the monitor circuit derives information on yarn breakage before and/or after the feeding device from the sensor signal or its variation with respect to time to generate a stop signal for the loom.
