Abstract: 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.

Abstract: 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.
