Abstract (en)
A static pressure control method includes a startup process of activating a suction blower (41) so that a static pressure of a suction airflow becomes higher than a predetermined set value (P1) at a time of startup of a plurality of winding units (2); an initial feedback process of feedback controlling a frequency of the suction blower (41) to lower the static pressure of the suction airflow to the set value (P1) after the startup process; and a normal feedback process of feedback controlling the frequency of the suction blower to maintain the static pressure of the suction airflow at the set value (P1) after the initial feedback process. A control period in the initial feedback process is shorter than a control period in the normal feedback process.
