Provided is a yarn manufacturing apparatus capable of speeding up the manufacturing of carbon nanotube yarn. A yarn manufacturing apparatus (1) is provided with a yarn manufacturing unit (5) for aggregating a group of travelling carbon nanotube fibers (F). The yarn manufacturing unit (5) has: a nozzle body (10); a first nozzle (20) which is provided in the nozzle body (10) and which generates, by compressed air, a first swirl flow (SF1) in a direction perpendicular to the travelling direction of the group of carbon nanotube fibers (F); and a second nozzle (30) which is provided in the nozzle body (10) and which generates, by compressed air, a second swirl flow (SF2) in a direction that is perpendicular to the travelling direction of the group of carbon nanotube fibers (F) and that is opposite to the first swirl flow (SF1). The first nozzle (20) and the second nozzle (30) are disposed in the nozzle body (10) at different positions in the travelling direction of the group of carbon nanotube fibers (F). |
