ABSTRACT OF THE INVENTION An apparatus is claimed for maintaining the relative position between wire being fed onto a bobbin and wire wound about the bobbin for forming a coil comprising guide means for guiding the wire onto the bobbin, a sensing arm movably responsive to shifting of the wire upon winding thereof onto the bobbin and displacing means for synchronously displacing the guide means dependent upon the position of the wire wound about the bobbin. The displacing means comprises, prefer- rably, a balanced rotary hydraulic servo-valve, a shaft which connects the sensing arm and the servo-valve, and a hydraulic cylinder secured to the servo valve, shiftably moveable rela- tive to the bobbin, responsive to movement of the sensing arm, such that as the angle between the wire being fed onto the bob- bin and the wire wound about the bobbin changes, the sensing arm is displaced thereby actuating said displacing means and causing movement of said guide means thereby re-establishing the rela- tive position between the wire being fed onto the bobbin and wire wound about the bobbin. As the wire is fed onto the bobbin thereby forming a coil, the sensing arm shifts and, through the shaft, generates an error from null in the servo-valve. The hydraulic cylinder, secured to the servo-valve housing, shifts responsive to such error from null, thereby moving the guide means, through move- ment of the servo-valve and shaft, to re-establish such null.
