PURPOSE: A device for detecting threaded knots in a bobbin winder is provided to evenly wind thread in a bobbin by reducing tension deviation. CONSTITUTION: A device for detecting threaded knots in a bobbin winder comprises a knot detector(8). The sensor is installed in a fixing table of the bobbin winder basic body in order to detect knot. The knot detector comprises inner and outer friction discs(20,22) and an adjusting unit. The inner side friction disc guides threads to a fixed bar. A sensing operation board(30) is attached to the outer friction disc. The adjusting unit is installed in the outside of the outer friction disc and controls the elastic support power of the spring.
