Abstract
A friction false twisting unit having three spindles and respective plurality of disks on each spindle. One spindle and its disks are on a swingable housing which swings out with respect to a stationary housing holding the other two spindles. A lower thread guide is beneath the lowest disk on the first spindle on the swingable housing. The lower thread guide eyelet opening opens toward the front spindle on the stationary housing. The lowest disk on that spindle is a thread guide disk, not a texturing disk. An upper stationary thread guide above the disks has an eyelet opening toward the rear of the housing and toward a respective lateral side of the housing depending upon whether an S twist or a Z twist is being applied to the thread, and the center of the eyelet opening of the upper thread guide is off the center of the triangle defined by the spindles.
