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.

A method for preparing of a workstation of an air-jet spinning machine for the resumption of a yarn spinning process after an interruption includes inserting the yarn end into an inlet opening of the spinning nozzle and transporting the yarn in a reverse motion with aid of the spinning nozzle and a fiber feeding device to a guide channel disposed before the spinning nozzle. A spinning-in yarn end is formed on the yarn in the guide channel. A yarn reserve is formed in an underpressure yarn storage device in from of a yarn winding device. The reverse motion of the yarn to the guide channel is performed by reverse motion of a yarn drawing-off mechanism at the workstation. A workstation configured to perform the method is encompassed by the invention as well.

A method for operating a textile machine is provided to produce roving from a fiber bundle with a consolidating means, the roving having a protective twist. The produced roving is wound onto a tube with a winding device. During the winding process, the roving is guided a guide element arranged between the consolidating means and the tube, wherein the guide element exerts a decelerating effect on the roving. The decelerating effect is controlled during operation of the textile machine such that the decelerating effect is lower during a start procedure while the roving leaving the consolidating means is brought into contact with a tube or during a tube change while a wound tube is replaced by an empty tube than during a winding process that takes place between the start procedure and the tube change.

A spinning machine includes a plurality of work stations arranged side by side between two front-side ends along at least one longitudinal side of the spinning machine. Each work station has a draw-off device, and an individual drive for the draw-off device. Each work station further includes additional driven work elements for production and winding of a yarn, the additional work elements including at least a feed device, a spinning chamber, and a winding device. A suction device generates negative pressure at the work stations and includes at least one negative pressure source and at least two negative pressure channels. Each of the negative pressure channels extends in a longitudinal direction of the spinning machine only over one part of the work stations.

A spinning device for manufacturing a thread from a supplied fibre band by a circulating air flow having a hollow spinning cone arranged in a spinning housing, the spinning housing having an envelope wall arranged coaxially and at a distance from the spinning cone and forming an envelope gap, and a nozzle device to which compressed air can be applied for producing an air flow circulating the spinning cone in the envelope gap. The spinning device having the spinning cone and the envelope wall for forming a capacitor unit to have electrodes arranged opposite one another with the envelope gap interposed and forming an electrode pair. A method for monitoring the spinning operation on the spinning device is also provided.

The invention relates to a cleaning device for a yarn forming element of an air-spinning nozzle, to a spinning position of an air-spinning machine and to a method for cleaning a yarn forming element of this type. In order to provide a spinning position of an air-spinning machine and a method for cleaning a yarn forming element of an air-spinning machine which allow long and trouble-free operation with constant quality and strength of the yarn produced, it is provided that the cleaning device has a cleaning strip and a storage unit for providing and retracting the cleaning strip, a fixed end of the cleaning strip being fastened to the storage unit, and a free end of the cleaning strip being able to be provided for cleaning and retracted again after the cleaning. Furthermore, the cleaning device has a cleaning strip guide for feeding the free end of the cleaning strip to the yarn forming element of the air-spinning nozzle for mechanical cleaning.

A textile machine and associated method are provided for operating the textile machine that includes a plurality of workstations, wherein each workstation includes at least one stepper motor configured to drive an element at the workstation. The method includes measuring a load variable, for example a load angle, of the stepper motor and detecting an approach of the element to an end position based on changes to the load variable.
