ABSTRACT:
In the case of a process for producing a twisted yarn from slivers that are drawn to the desired size and subsequently are prestrengthened by means of pneumatic false twisting, it is provided that the fiber ends in the form of helixes are wound around the core with such a steep slope that, during the twisting, the fiber ends that were previously wound around the core are wound off the core as much as possible.
