An improved method for operating a textile machine having plural workstations comprising exchangeable components, each having a readable and writable transponder arranged on or integrated in the exchangeable components. During the lifecycle of the exchangeable components at least the operating data which influence the wearing of the exchangeable components are automatically stored on the respective transponder. Textile machines for carrying out the method are characterised by arranging in the region of each workstation at least one transceiver for writing and reading the transponders attached to or integrated in the exchangeable components.

Method for operating a textile machine

A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

A spinning rotor for use at high speeds in open-end spinning machines has a rotor cup having an annular wall portion defining a rotor opening, a bottom wall portion merging with the annular wall portion, and a mounting hub extending exteriorly from the bottom wall portion. A rotor shaft is affixed to the mounting hub coaxially with the rotor cup. The merger of the bottom and annular wall portions of the rotor cup defines a maximum exterior diameter of the rotor and an interior rotor groove. The annular wall portion, the bottom wall portion and the mounting hub are of different cross-sectional thicknesses with the cross-sectional thickness of the bottom wall portion increasing from the rotor groove to the mounting hub. The wall thickness is less than 1.2 mm in the area of the maximum exterior diameter of the rotor cup () and the rotor cup has an aerodynamic exterior contour free of edges for deterring turbulent boundary layer air flow thereabout and an interior contour for promoting fiber spinning into a yarn.

An apparatus removes textile articles such as empty tubes or full yarn packages from the individual posts on which such articles are supported simultaneous with advancing movement of the posts. The textile articles are removed in a direction generally parallel to the axis of the posts so that during removal detrimental binding of the textile article relative to the post does not occur. According to one aspect of the invention, at least one pair of endless belts are mounted in spaced, parallel relation to one another to form an elongate opening therebetween. The elongate opening is aligned with the travel path of the textile articles being advanced on the posts so that the textile articles automatically enter the elongate opening and are engaged by the endless belts without the need to stop or otherwise control the advancing movement of the textile articles. In another aspect of the invention, a pair of spaced, parallel elongate rollers are provided, the elongate rollers being rotated in opposite directions to effect removal of a textile article which has been advanced into the elongate opening formed between the rollers. The textile article removal apparatus preferably also includes a collection assembly for collecting removed textile articles in an orderly manner and an assembly for transporting loads of removed textile articles to a location for further handling.
