A monitor and malfunction detector for the thread feed of a textile machine. The monitor combines electronic information and mathematical analysis of the movement of the thread, including speed, tension and fiber and consistency, thereby permitting the determination of: 1) presence of knots and inconsistencies in the thread 2) the operating status of the textile equipment and thread feed; 3) the prediction of problems based upon the change of operating characteristics including speed, tension, draw and duty cycle patterns; 4) the control of the textile machine being monitored; 5) the diagnosis of mechanical faults; 6) production accounting; and 7) needle burr detection. The monitor also employs a unique signal comparison incorporating differential circuitry, pattern recognition, and averaging functions to achieve these goals efficiently and reliably as well as means to reduce or eliminate the effect of undesirable electromagnetic transients on the operation of the textile machine.
