A spinning station of a spinning machine for producing a thread from a sliver. A thread end is taken up by a take-up device and transferred to a preparation device downstream from a vortex chamber of the spinning device, the thread end is subsequently treated in the preparation device and then transferred to the vortex chamber, a drafting system for supplying a sliver to the vortex chamber is powered up, wherein an exit roller pair of the drafting system is accelerated to a predetermined draw-off speed, and the sliver is spun onto the thread end in the vortex chamber and a draw-off device for drawing off the thread spun in the vortex chamber is powered up and accelerated up to the draw-off speed. The speed of the exit roller pair and/or of the draw-off device increases non-linearly and/or approaches the predetermined draw-off speed non-linearly around the end of powering up.

Spinning station of an air-jet spinning machine and method for carrying out a piecing process at such a spinning station

A drafting system for conveying a sliver to an inlet opening of a vortex chamber of an air-jet spinning device, for a drafting system having an exit roller pair and at least one additional drafting system roller pair and/or apron roller pair. A sliver is supplied at a spinning station of an air-jet spinning machine for the production of a thread to the vortex chamber. The exit roller pair can be driven decoupled from the at least one additional pair of drafting system rollers and/or apron rollers. In the method, the roller pair is driven for combing the sliver end after a spinning interruption at a predetermined combing speed and the at least one stretching mill roller and/or belt roller pair upstream of the starting roller pair is stopped or operated at a holding speed associated with the combing speed, which is at most 10% of the combing speed.

Sliver preparation

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.

Cleaning device for a yarn forming element of an air-spinning nozzle and method for cleaning a yarn forming element of this type

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.
