Abstract (en)
[origin: EP2302115A1] A spinning frame includes a yarn accumulating roller (21), a yarn hooking member (22), a yarn removing lever (28), a suction pipe (44), and a unit controller (60). The hooking member (22) can wind a spun yarn (10) around the yarn accumulating roller (21). The yarn removing lever (28) can remove the spun yarn (10) from the yarn hooking member. The suction pipe (44) can catch a yarn end of the spun yarn (10) and includes a twisting nozzle (67) capable of applying twists to the caught spun yarn (10). The unit controller (60) controls the twisting nozzle (67) to operate while the spun yarn (10) caught by the suction pipe (44) is being wound around the yarn accumulating roller (21), and controls the twisting nozzle (67) to stop before the yarn removing lever (28) removes the spun yarn (10) from the yarn hooking member (22).
