Abstract

The invention relates to a spinning station of an air-jet spinning machine for producing a thread from a sliver, and to a method for carrying out a piecing process at such a spinning station, wherein a thread end that has run onto a take-up bobbin is taken up by means of a thread take-up device and transferred to a thread-end preparation device arranged downstream from a vortex chamber of the air-jet spinning device in the thread running direction, the thread end is subsequently treated in the thread-end preparation device and then transferred to the vortex chamber of the air-jet spinning device and positioned there, a drafting system for drafting and 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 wherein the sliver is spun onto the prepared thread end in the vortex chamber and a motor-driven draw-off device for drawing off the thread spun in the vortex chamber is powered up and thereby accelerated up to the draw-off speed. In order to provide a method for carrying out a piecing process and an air-jet spinning machine which allow a reliable piecing process, it is provided that the drafting system and/or the draw-off device are powered up in such a way that the speed of the exit roller pair and/or of the draw-off device increases non-linearly at the beginning of powering up and/or approaches the predetermined draw-off speed non-linearly around the end of powering up.
