PROBLEM TO BE SOLVED: To provide a device for producing a yarn from fiber bundles, in which a rotated air flow is loaded on fibers in a nozzle block 20 having one or a plurality of nozzles 21, thereby rotating the fibers in the inlet port of the yarn path of a spindle 32 to form the yarn, wherein the fibers are transported to the nozzle block through fiber transport paths 14, 15 for guiding the fiber bundles and through a prescribed formed means between a fiber delivery site and the inlet port of the spindle, and wherein the core fibers and the outer peripheral fibers are maintained to give the optimal number of fibers and the optimal wound length. SOLUTION: The path 14 has larger central transport length 24, 12 than the central transport length 24, 13 of the path 15.
