Abstract

In a process and arrangement for false-twist spinning, it is provided that, by use of an air current in the delivery area of a drafting unit, an increased number of fiber ends are spread away which subsequently, in a controlled manner, are wound around the sliver by means of a guiding element moving in the travelling direction of the sliver and holding the spread-away fiber ends.
