ABSTRACT:
The apparatus comprises at least two spaced parallel discs having a relatively small thickness and mounted on one rotary shaft, and an intermediate disc having a relatively large thickness and mounted on the other shaft between the discs of small thickness. The two shafts are spaced from each other and the discs having small and large thicknesses have diameters such that the peripheral portions of the discs overlap one upon the other to form intersections therebetween on the rear and front sides. The yarn to be twisted is threaded through an intersection on the rear side, about the periphery of the intermediate disc and then through an intersection on the front side.
