Abstract
A linear course of thread is required for a high speed friction false-twisting unit. For this purpose, the region of travel of the thread through the center of a three spindle disk set triangle should be freely accessible. One of the disk sets is adapted to be swung out on a lever from the other two disk sets. A toothed belt drive is used both in the case of a tangential belt drive and in units driven by an electric motor. A further advantage is that this arrangement can be used in units which have the possibility of a change of the center-to-center distance. The belts from driving rollers which drive the disk set spindles are held outside the center of the disk triangle through which the thread passes.
