PURPOSE: To prevent ribbon winding generated due to a diameter rate by comparing each angle of rotation of a thread guiding drum and a twilled fabric winding bobbin rotating in contact with this thread guiding drum, and confirming the deflection of the angle of rotation as the start of ribbon winding, and interfering the winding process with braking at the latest.

CONSTITUTION: A thread 2 is supplied through a guide ring 4 to a guide groove 5 of a guide drum 3 at a winding part 1. Then, the thread 2 is wound around a twilled fabric winding bobbin 8 by the guide drum 3. In this case, the guide drum 3 is driven by an electric motor 17, and the twilled fabric winding bobbin 8 is brought into contact with the peripheral face of the thread guide drum 3, and simultaneously driven. At that time, each angle of rotation signal generator 22 and 21 is respectively installed at the guide drum 3 and the twilled fabric winding bobbin 8, and each angle of rotation signal is inputted to a controller 20 equipped with a calculator 23. On the other hand, a prescribed control signal is outputted from the controller 20 through a power inverter 18 to an electric motor 17, That is, the deflection of each angle of rotation signal is confirmed as the start of ribbon starting, and the winding process is interfered with braking at the latest.
