Abstract (en)

In a spinning frame (1), opening / closing members (a first opening / closing member (65) and a second opening / closing member (66)) are arranged in a flow path in which a suction current (82, 83) generated by at least one of a section blower (32) and a main blower acts in each of section ducts (31). Supporting members openably / closably support the opening / closing members (65, 66) to change an open / closed state of the flow path according to difference between a pressure at an upstream side and a pressure at a downstream side of the opening / closing members.
