Abstract (en)

A spinning machine includes a spinning device (9), a winding device (13), a yarn accumulating roller (21), a yarn hooking member (22), and a yarn removing lever (28). The yarn accumulating roller (21) winds spun yarn around an outer peripheral surface thereof and rotates with the spun yarn wound around to feed the spun yarn from the spinning device (9) while applying tension to the spun yarn. While being engaged with the spun yarn, the yarn hooking member (22) rotates integrally with the yarn accumulating roller (21), and thus prevents the spun yarn from being unwound from the outer peripheral surface of the yarn accumulating roller. The yarn removing lever (28) is arranged downstream of the yarn hooking member (22) in a yarn transporting direction, and can be moved between a lowered position where the yarn removing lever (28) does not make contact with the spun yarn and a lifted position where the yarn hooking member (22) makes contact with the spun yarn. At the lifted position, the yarn removing lever (28) removes the spun yarn from the yarn hooking member (22).
