The diffuse reflection photoelectric sensor 903 moves from the origin by the stepping slider module 904904 to sense the cloth width. The diffuse reflection photoelectric sensor 903 gives a switch signal and transmits it to the width measurement system. The width measurement system calculates the number of steps to obtain the cloth width, thereby achieving the use effect of automatic cloth width measurement;
