Abstract
When a residual amount R of a roving required to make a bobbin full at a desired stopping position A of the bobbin rail which moves upwardly is smaller than the amount (4.times.L) corresponding to remaining four layers of the roving for a normal winding process, a desired amount Q is calculated as the residual amount R divided by 4. The switching of the roving during the downward movement of the bobbin rail is done when the amount of the roving from the top end of the bobbin rail is equal to the desired spinning amount Q. This operation is repeated until a full bobbin amount is detected by an encoder, and the flyer frame is stopped.
