ABSTRACT:
A spindle drive type yarn winding apparatus of the bobbin changing type includes a motor for driving a bobbin holder; an inverter for supplying electric power to the motor; a contact roller for contacting with and driven by a bobbin inserted on the bobbin holder or a package wound on the bobbin; a controller for performing at least integral control action to the motor so as to control the rotating speed of the contact roller at a predetermined value; a setter which sets the winding speed, density of the wound package, stroke of the wound package and denier of the wound package, a first arithmetic circuit which calculates the diameter of the wound package; a second arithmetic circuit which calculates a gain of the controller based on winding conditions set by the setter, and diameter calculated by the first arithmetic circuit; and an altering device which alters the gain of the controller based on at least one factor set by the setter and the diameter of the wound package calculated in the first arithmetic circuit.
