ABSTRACT:
In a method for manufacturing a twisted yarn a spindle rotor is positioned in a stationary cylinder housing. At least two spinning devices are supported in a receiving chamber of the spindle rotor such that the spinning devices are located adjacent to one another and symmetrical to the central axis of the spindle rotor. A vacuum is generated within the receiving chamber. Dissolved fiber material is supplied from a fiber supply device to the hollow spindle axle of the spindle rotor. The individual fiber material is fed by the vacuum within the receiving chamber via the hollow spindle axle 6 of the spindle rotor 7 and via feed channels, connecting the hollow spindle axle to the spinning rotors, to the spinning devices. From the dissolved fiber materials spun yarns are spun in each one of the spinning devices. The spun yarns are gathered as a twisted yarn at a centering point positioned on the extension of the central axis of the spindle rotor. The twisted yarn is wound onto a spool.
