Abstract

The invention relates to a detection system (1) for detecting and avoiding knots and/or irregularities in weft yarns (10) when weaving a fabric on a weaving machine (20), where the knot and/or the irregularity may be manually removed by stopping the weaving machine or may be automatically removed by having a colour selector stop, and the detection system (1) being provided with one or several knot detectors (4) to detect the knots and the irregularities of the weft yams (10) and which is provided, when detecting a knot and/or an irregularity of the weft yarn (10), to determine the length of the weft yarn (Lt) between the knot and/or the irregularity and the weaving machine and provided to activate the weaving machine (20) to continue its weaving operation until the moment that the length of the weft yarn (Lt) between the knot and/or the irregularity and the fabric equals the width of the fabric, and at that moment, to send a signal to the weaving machine (20) in order to stop the weaving machine or the colour selector in order to remove the knot and/or the irregularity manually, respectively automatically. <IMAGE>
