ABSTRACT:
In a method for manufacturing a twisted yarn by an integrated spinning-twisting process a vacuum is generated within the spindle rotor. Individual staple fibers are fed by vacuum to at least two rotor spinning devices positioned within the spindle rotor in which individual spun yarns are spun from the individual staple fibers. The individual spun yarns are gathered and guided in a first direction through the spindle rotor in order to subject the individual spun yarns to a first twist. The twisted yarn is guided in a second direction counter to the first direction to a centering element positioned above the rotor spinning devices whereby the twisted yarn forms a rotating yarn balloon about the spindle rotor. The twisted yarn is then wound onto a bobbin. Feeding of the individual staple fibers includes supplying them essentially in a radially inward direction through a fiber material feed tube to an annular space, positioned at the spindle rotor coaxially to a central axis of the yarn balloon, and from the annular space through respective fiber material supply channels to the at least two rotor spinning devices. The envelope of the yarn balloon extends through the annular space and the individual staple fibers pass through the yarn balloon. In the step of guiding the twisted yarn in a second direction counter to the first direction the twisted yarn is routed through a yarn guide element rotating with the yarn balloon.
