Method and device for directly manufacturing a twisted yarn from dissolved fiber material

A device for manufacturing a twisted yarn, said device comprising:

• a rotating spindle rotor comprising a hollow spindle axle and a receiving chamber;
• at least two spinning devices positioned in said receiving chamber of the spindle rotor such that said spinning devices are positioned adjacent to one another and symmetrical to a central axis of the spindle rotor;
• a vacuum source for generating a vacuum within said receiving chamber;
• a vacuum chamber connected to said vacuum source and communicating with said receiving chamber, said vacuum chamber at least partially surrounding said spindle rotor;
• a fiber supply device for supplying dissolved fiber material to a free end of said hollow spindle axle of the spindle rotor;
• said hollow spindle axle having an inner end remote from said free end;
• feed channels connected to said inner end of said hollow spindle axle and extending to said spinning devices, wherein the dissolved fiber material is fed by the vacuum within the receiving chamber via said hollow spindle axle of the spindle rotor and via said feed channels to said spinning devices for spinning from the dissolved fiber material spun yarns in each one of said spinning devices;
• a centering point for gathering the spun yarns as a twisted yarn, said centering point positioned on an extension of the central axis of said spindle rotor;
• and
• wherein said vacuum source generates a vacuum via said vacuum chamber and said receiving chamber within said hollow spindle axle and said feed channels for supplying the dissolved fiber material to said spinning devices.
