(54) Spinning machine


(57) A spinning machine (100) is provided with a plurality of spinning units (1), each of which has an air-jet spinning device (6) that twists a fiber bundle F using a whirling airflow. The spinning machine (100) includes an air transporting device (21) that transports air, an air pipe (22) that guides the air transported by the air transporting device (21), an additive supplying device (3) that supplies an additive to the air pipe (22) at upstream of a branch where the air flowing through the air pipe (22) branches off towards the air-jet spinning devices (6), and a control device (C) that adjusts the volume of an additive to be supplied by the additive supplying device (3).
