Abstract (en)
The device consists of a flange (15) that is solid with a draft roller (7) of the spinning unit. The flange forms a convex surface of revolution coaxial to the said roller (7) and is facing towards the pressure roller (8) placed against the draft roller. An adjustable thread guide (13) imposes to the slubbing (2B) that has to be processed, such a trajectory that the slubbing leans against said convex revolving surface, which in this way imposes an adjustable false twist to the slubbing, in the tract (2B) of path subject to drafting. <IMAGE>
