Abstract: The invention relates to a spinning means for a work station of a textile machine having a plurality of work stations, comprising a first spinning means identification for identifying and/or authenticating the spinning means at a work station. Furthermore, the invention relates to a textile machine having a plurality of work stations and a method for operating the same, wherein the work stations have replaceable spinning means, each having a first spinning means identification. In order to provide a spinning means that has a particularly forgery-proof spinning means identification, it is provided that the first spinning means identification is formed by at least one specific, sensor-detectable material property of a spinning means material and/or a coating applied to the spinning means material.

Abstract: Fibre band opening device for an open-end spinning device having a feed tray, a fibre band pull-in cylinder, and an opening roller having an opening roller clothing, the tips of which lie on a circular cylindrical surface, a support surface for fixing a fibre tuft, which is processed by the opening roller by combining, the distance of which support surface from the circular cylindrical surface is tapered in the fibre transport direction to a minimum distance, and a transition area having a convex curvature between the clamping surface and the support surface. The support surface has a distance of between 4 and 8 millimetres from the circular cylindrical surface at the beginning of the support surface with respect to the fibre transport direction, and the minimum distance of the support surface from the circular cylindrical surface is less than 1.5 millimetres.

Abstract: Fibre band opening device for an open-end spinning device and feed tray for the fibre band opening device. The feed tray has a clamping surface, which is designed to transport, in conjunction with a fibre band pull-in cylinder, a feed fibre band towards an opening roller having an opening roller clothing, the tips of which lie on a circular cylindrical surface, a support surface for fixing a fibre tuft, which is processed by the opening roller by combining, the distance of which support surface from the circular cylindrical surface is tapered in the fibre transport direction to a minimum distance, and a transition area having a convex curvature between the clamping surface and the support surface. The support surface has a distance of between 4 and 8 millimetres from the circular cylindrical surface at the beginning of the support surface with respect to the fibre transport direction, and the minimum distance of the support surface from the circular cylindrical surface is less than 1.5 millimetres.

Abstract: A fibre guide insert for an opening roller housing, with an insert body to be pushed into a mounting opening of the opening roller housing, the insert body having a fibre guide surface forming a fibre channel inlet and a fibre channel connection section connected to a fibre channel input. An opening roller housing for an opening device of an open-end rotor spinning device, having a fibre channel leading into an opening roller housing interior, where it adjoins a fibre channel input for fibres, and a mounting opening for a fibre guide insert, which mounting opening is open towards the opening roller housing interior.
