ABSTRACT:
A yarn guide device for the formation of cross-wound bobbins in textile machines, comprising a driven cylinder having over the entire length of its outer surface an uninterrupted helical groove for guiding the yarn in one direction of the transverse movement with respect to the direction of the run movement of the yarn and a helical groove running in the opposite direction and interrupted by the first groove for guiding the yarn in the other direction of the transverse movement of the yarn; a rotating driven rotor installed before and under said driven grooved cylinder; said rotor including at least one carrier for pre-aligning the yarn during its transverse motion imposed by the uninterrupted groove of said grooved cylinder; and means for driving the rotor with a speed having an unchanging relationship to the speed of rotation of the grooved cylinder.
