Abstract
The double torsion twisting mechanism includes a rotatable spindle which rotatably supports a bobbin. A coupling unit connected to the bobbin has its axis offset to the bobbin axis to prevent rotation of the bobbin. A yarn ballooning plate is secured to the spindle and rotates the coupling unit via a flexible membrane connected between the plate and the coupling unit. The flexible membrane is cut-out in the region of a radial yarn guide channel which rotates with the spindle.
