Abstract: Automatic operation of a ring spinning system containing a ring spinning machine having spinning positions and a winding machine having winding positions. Yarn is spun at one of the spinning positions and wound up to a cop. Values of a parameter characteristic for the operation of the spinning position are determined during the winding of the cop and stored as spinning data that is assigned to the cop.
