A yarn producing apparatus 1 is an apparatus for producing CNT yarn Y from CNT fibers F while allowing the CNT (carbon nanotube) fibers F to run. The yarn producing apparatus 1 includes a wind driving mechanism 20 configured to allow a winding shaft 21 provided with a winding tube T to rotate about a winding centerline of the winding shaft 21 to thereby wind the CNT yarn Y onto the winding tube T, a twist driving mechanism 30 configured to allow a guide 31 to rotate around the winding tube T, the guide 31 configured to guide the CNT yarn Y to the winding tube T, to thereby twist the CNT fibers F and produce the CNT yarn Y while allowing the CNT fibers F, CNT yarn Y, or both to swirl, and a traverse driving mechanism 40 configured to allow the guide 31 to reciprocate relative to the winding tube T along the winding centerline of the winding shaft 21 to thereby allow the CNT yarn Y to traverse the winding tube T.

A yarn producing apparatus is provided that produces high-density carbon nanotube yarn at high speed. The yarn producing apparatus 1 includes: a substrate support 3 supporting a carbon nanotube (CNT) forming substrate S; a winding device 9 configured to continuously draw CNT fibers F from the CNT forming substrate S supported on the substrate support 3 and to allow the CNT fibers F to run; and a yarn producing unit 5 provided between the substrate support 3 and the winding device 9 to directly take in the CNT fibers F drawn by the winding device 9 and twist the taken-in CNT fibers. The yarn producing unit 5 false-twists the CNT fibers F with a swirl flow of compressed air.
