Abstract (en)

An air-jet spinning machine (1) includes a draft device (6), a pneumatic spinning device (7), and a detecting device (8, 9, 36, 38, 39, 51) adapted to detect a presence or an absence of the yarn (Y). The draft device (6) includes a moving section (100) adapted to move a top roller (17b) between a contacting position and a separated position, the contacting position being a position where the top roller (17b) makes contact with a bottom roller (17a) and the separated position being a position where the top roller (17b) is located away from the bottom roller (17a) and an inlet (7a) of the pneumatic spinning device (7). The moving section (100) moves the top roller (17b) to the separated position at interruption of spinning operation.
