Abstract (en)
[origin: WO2019227241A1] The invention relates to a method for operating a ring spinning system (1) which contains a ring spinning machine (2) with a plurality of spinning points (21) and a winding machine (3) with a plurality of winding points (31). Yarn (92) is spun on one of the spinning points (21) and is wound into a cop (91). Values of a spinning parameter are ascertained at different points in time during the winding process of the cop (91) and stored as spinning data. The cop is transported from the spinning point (21) to one of the winding points (31). The yarn (92) is rewound from the cop (91) onto a yarn bobbin (93) at the winding point (31). Values of a yarn parameter are ascertained at at least two different points in time during the rewinding process of the cop (91) and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other so as to relate to the same yarn section. An operation is carried out on the ring spinning machine (2) on the basis of the mutually assigned spinning data and yarn data.
