ABSTRACT OF THE INVENTION An apparatus is claimed for maintaining the relative position between wire being fed onto a spool and wire wound about the spool for forming a coil comprising guide means for guiding the wire onto the spool; a sensing arm movably responsive to shifting of the wire upon winding thereof onto the spool and displacing means for synchronously displacing the guide means dependent upon the position of the wire wound about the spool. The displacing means comprises, preferrably, a 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 movable relative to the spool, responsive to movement of the sensing arm, such that as the angle between the wire being fed onto the spool and the wire wound about the spool changes, the sensing arm is displaced thereby actuating said displacing means and causing movement of said guide means thereby re-establishing the relative position between the wire being fed onto the spool and wire wound about the spool.
