ABSTRACT:
A method and apparatus for operating an open-end friction spinning machine with a plurality of spinning units whereby yarn twist of yarn at the spinning units is monitored by a measuring and evaluating device. This monitored yarn twist is then compared with a predetermined desired yarn twist value. In response to deviations from the predetermined desired yarn twist, at least one parameter of spinning conditions is adjusted.
