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.

A ring spinning machine includes a reciprocating, displaceably supported spindle rail that is driven by a motor via a shaft that passes through the ring spinning machine. The spindle rail is arranged along opposite sides of the ring spinning machine in a longitudinal orientation of the ring spinning machine and is subdivided into sections along each of the opposite sides. Cross braces extend between the opposite sides of the ring spinning machine and connect opposite sections of the spindle rail. The shaft is supported between the sections of the spindle rail. The spindle rail is suspended from at least one cam disc that is seated on the shaft. A circumferentially biased spring is configured with the shaft or the cam disc to provide torsional compensation on the shaft.

A device for piecing a thread at a workstation of a textile machine includes a suction nozzle configured to pick up a thread end of the thread from a bobbin, the suction nozzle including an entry opening for the thread. A feeder unit is movable with respect to the suction nozzle and includes a cover element configured to close the entry opening in a first position (I) of the feeder unit and to unblock the entry opening in a second position (II) of the feeder unit. The cover element includes a thread-guiding element having an open contour.

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.
