A spinning frame includes a yarn accumulating roller (21), an electric motor (25), and a unit controller (60). The yarn accumulating roller (21) temporarily accumulates a spun yarn produced by a spinning device (9) by winding the spun yarn around an outer peripheral surface thereof and rotating. The electric motor (25) drives and rotates the yarn accumulating roller (21). The unit controller (60) carries out a first control to control the electric motor (25) to rotate the yarn accumulating roller backward when it is necessary to unwind the spun yarn wound around the yarn accumulating roller. Next, the unit controller (60) carries out a second control to control the electric motor (25) to rotate the yarn accumulating roller (21) backward at a speed which is higher than a rotational speed during the first control. Then, the unit controller (60) carries out a control to spin off a yarn entangled with a flyer (38) or the like by temporarily increasing a backward rotational speed of the yarn accumulating roller (21) during the second control.
