Abstract: A spinning element of an air-jet spinning nozzle for an air-jet spinning machine for producing a yarn from a sliver using an airflow. The spinning element of the air-jet spinning nozzle for the air-jet spinning machine and a corresponding air-jet spinning nozzle allows a particularly inexpensive, low-maintenance, and simple operation of an air-jet spinning machine without compromising the quality and strength of the air-jet spun yarn and without requiring frequent cleaning. This is achieved in that the spinning element has at least one fibre- and/or thread-guiding surface, an anti-adhesive coating being located on at least some sections of the fibre- and/or thread-guiding surface.

Abstract: A spinning position of an air-spinning machine and method of cleaning a yarn forming element of an air spinning nozzle are provided. The spinning position has an air spinning nozzle with a yarn forming element arranged within a vortex chamber for producing a yarn from a fibre band supplied to the air spinning nozzle, in which case the air spinning nozzle can be transferred from a closed state for yarn formation to an open state in which the yarn forming element can be cleaned. At least one cleaning nozzle for cleaning the yarn forming element in the open state of the air spinning nozzle is arranged at the spinning position, the cleaning nozzle being positioned and/or aligned or positionable and/or alignable, such that, at least in the open state of the air spinning nozzle, the yarn forming element can have a cleaning medium applied to it through the cleaning nozzle.

Abstract: A method for arranging a fibre strand on a spinning device of a spinning station, wherein the spinning device is fed the fibre strand in order to produce a spun thread from the fibre strand by means of a drafting unit having a plurality of roller pairs. The roller pairs of the closed drafting unit are each operated, in a manner corresponding to the predefined drafting ratio of the fibre strand, with an introduction speed lower than the operating speed of the drafting unit, the fibre strand is subsequently introduced into the clamping region of an input roller pair of the drafting unit and the drafted fibre strand, after passing through the closed drafting unit and exiting a clamping region of an output roller part of the drafting unit, is subsequently fed to the spinning device.

Abstract: A top apron cradle for an apron drafting system of a textile machine with an apron guide unit for circumferentially guiding a top apron looped around a top roller of the apron drafting system. The apron guide unit has an apron guide section for guiding the top apron, the apron guide section having an entrance section and a deflection section. The apron guide unit has a receptacle, which is assigned to the entrance section, for a replaceable tensioning element which can be brought into pressure contact with an inner side of the top apron, and the tensioning element. For guiding the top apron via the tensioning element and the deflection section, the receptacle and the tensioning element replaceably accommodated in the receptacle are formed at a distance from the area of the apron guide section enclosed by the tensioning element and the deflection section.

Abstract: A compactor device for compacting a sliver that is drawn by a drafting system of a textile machine is provided. In accordance with the invention, it is envisaged that the compactor device is designed as a channel compactor and has a guide channel, designed in the shape of a screw in the running direction of the sliver, wherein the entry opening of the guide channel is widest horizontally and the exit opening of the guide channel is arranged rotated at least 30° with respect to the entry opening.
