Abstract
In a method and device for manufacturing a twisted yarn a spindle rotor having a hollow spindle axle with inlet and outlet and a yarn guide channel extending radially outwardly from the outlet is provided. The yarn exiting the yarn guide channel forms a yarn balloon. A stream of dissolved fiber material is fed axially through the spindle rotor into the space delimited by the yarn balloon and is divided into two partial streams. Each partial stream is guided first radially outwardly, then upwardly substantially parallel to the hollow spindle axle to a predetermined level, and subsequently radially inwardly to a respective spinning device arranged within the space delimited by the yarn balloon. A fiber is spun in each of the spinning devices, withdrawn, and guided axially downwardly. The fibers together are fed into the inlet of the hollow spindle axle to form a yarn. The yarn is guided through the hollow spindle axle and the yarn guide channel from where it exits and forms the yarn balloon. In the balloon the yarn is guided in a direction parallel to the upward direction of the partial streams to a centering element positioned on an extension of the axis of the hollow spindle axle such that the partial streams maintain a constant distance to the yarn in the yarn balloon.
