A disk combination which permits a thread false-twisting device to be operated at a high withdrawal speed is disclosed. The false-twisting device has three parallel rotatable shafts. On a first shaft is a first inlet guide disk for guiding entering thread into a thread path. A second inlet guide disk on a second shaft guides the thread along the path. After the second inlet guide disk, a first working disk on the first shaft begins false-twisting the thread. The first working disk may be one of five working disks, each of which is positioned in the rotational direction from the preceding disk. After the last of the working disks the exiting thread contacts an outlet guide disk, also positioned in the rotational direction from the preceding disk. The disks may be made of a soft material, such as polyurethane, or may be rigid disks coated with a hard material such as nickel containing diamond particles. The thread can be drawn through the device at a speed in excess of 600 meters per minute.
