Abstract (en)
[origin: WO2005031051A1] Disclosed is a device for false-twisting a synthetic thread, comprising several shafts that are rotatably mounted on a bearing block. Said shafts are arranged at a respective axial distance from each other so as to form a triangle. Several friction disks are mounted on the shafts so as to be offset relative to each other. The friction disks have a diameter that is large enough for the friction disks to overlap in the center of the triangle while the circumferential surfaces thereof form a wound thread course. In order to lower the thread tension at high production speeds while obtaining a great twisting effect, the degree of overlapping of the friction disks is determined by a ratio between the disk diameter and the axial distance, which is >1.45, the friction disks having a width ranging between 9.5 mm and 11.5 mm.
