Abstract
In a textile winding machine of the type wherein yarn is cross-wound onto a bobbin peripherally driven by a friction roller, the winding operation may be monitored and controlled to achieve a high winding quality by constantly varying the time period per revolution of the friction roller, constantly measuring the respective time periods per revolution of the bobbin and the roller, at least intermittently comparing the measured revolution time periods, and regulating the friction roller drive or stopping the winding operation altogether or otherwise intervening in the winding operation as a function of deviations of the comparison result from established theoretical values.
