Abstract
In a method and apparatus for manufacturing a yarn from fiber material at least two spinning devices arranged adjacent to one another are provided. Fiber material is dissolved and fed to the at least two spinning devices. Each spinning device generates an individual spun fiber. The individual spun fibers are combined at the inlet opening of a hollow spindle axis to form a yarn. The yarn undergoes a two-for-one twisting operation by being passed in a first yarn feeding direction through the hollow spindle axis to an outlet opening of the hollow spindle axis, then radially guided from the outlet opening, and guided in a second yarn feeding direction counter to the first yarn feeding direction to form a yarn balloon rotating in a direction of rotation about the at least two spinning devices. A centering element is arranged on an axis extending along the hollow spindle axle so as to be spaced from the inlet opening of the hollow spindle axle. The yarn is fed from the yarn balloon via the centering element to a winding device.
