Optical Sensors for Control in Textile Industry

The proposed paper presents optoelectronic sensors for detection of a lack of thread in two types of textile machines. Possible reasons for this failure may be thread breaks or running out of material in the supply bobbin. The application of this method results in a rapid and timely stop of the workflow and reduces the time for restoring the operation of machines. This leads to an increase in l...
