A friction false-twisting unit has three upstanding parallel shafts supported on a base plate. Each shaft carries a plurality of friction disks and the disks are overlapping and interleaved for applying a false twist to filament yarn drawn through the array of disks where they overlap. To damp the oscillation of the entire false twisting unit, it is fastened to the machine bed through interposed damping elements. There is a holding mandrel on the base plate which passes through a guide sleeve. The guide sleeve is, in turn, attached to the mount via the damping elements. With the false-twisting unit absent, the damping elements tilt the guide sleeve and when the unit is in place, its weight in use returns the guide sleeve to a correct orientation, so that the plane of the side of the drive whorl on one of the shafts is parallel to the plane of the tangential drive belt for that shaft where that belt passes the drive whorl.
