PROBLEM TO BE SOLVED: To reduce a clogging tendency to improve the operation stability and reliability of a spun yarn-producing apparatus which is used for producing a spun yarn (1) from a stable fiber bundle (2), comprises a drawing frame (3) having a feed roller pair (9, 10), an air nozzle device (4) disposed on the downstream side of the drawing frame (3) and including a turbulence chamber (13) equipped with an exhaust line (16), and a cleaning line (20) whose suction port (19) is disposed near to the feed rollers (9, 10), wherein the exhaust line (16) is formed as a circular line (17) surrounding a fixed spindle-like member (18) at least in its starting region, and the cleaning line (20) is integrated with the exhaust line (16) and connected to their common negative pressure source (24). SOLUTION: This spun yarn-producing apparatus is characterized in that the cleaning line is first integrated with the exhaust line behind the circular line in the air-flowing direction.
