Abstract (en)
[origin: WO0204722A1] The invention relates to a device and method for producing an automatically twisted yarn (1), wherein at least two roves (2, 3) are initially guided between at least one false twisting device (4); the roves (2,3) are periodically and alternately provided with areas consisting of S and Z shaped twists which are separated from each other by areas devoid of twists (0), and the roves (2, 3) are subsequently combined in such a way that they become automatically twisted as a result of their own twists; the areas devoid of twists (0) are provided with a phase difference ( phi in the automatically twisted twined yarn (1). In methods and devices known per se used to carry out such methods, the rove threads often break and the automatically twisted yarn (1) lacks resistance. The aim of the invention is to provide a method and device for producing an automatically twisted yarn (1) which is as resistant as possible. The phase difference ( phi is thus produced by using at least one deflection roller (5) to guide at least one of the roves (2) onto a guide roller (6) once it has passed through the false twisting device (4), whereupon the roves (2, 3) are combined on the guide surface (6a) of the guide roller (6).
