After recording the image (32), the container (16) is closed in order to avoid the fragments (10) of the needle (11) being lost away from the sewing workstation.

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. The spinning data assigned to the cop is taken into account when deciding whether to feed the cop after it has been set down to one of the winding positions. The assignment is based on an identification of a point in time of winding of the cop and an identification of the spinning position at which the cop was wound.
