In a toroidal coil winding machine to wind a tape or heavy wire on a toroidal core, the shuttle retains a length of wire or tape formed into a coil. A roller system is driven to support and maintain the inner diameter of the coil constant and the wire or tape is payed out from the inner diameter, to avoid stress on the wire or tape. An air motor independently drives a tension control roller which controls the pay-out tension without imparting undue stress to the wire or tape.

A coil winding machine adapted to wind an elongated conductor about a toroidal core having a hole therethrough, the coil winding machine including a base, and mounted thereon: clamp means to removably hold a toroidal core; shuttle means rotatably mounted on said base and including a ring-like shuttle magazine which passes through said toroidal core hole, said shuttle magazine removably retaining therein a length of the elongated conductor formed in a coil; drive means to rotate said shuttle magazine in one direction to load said elongated conductor into said shuttle magazine and in the opposite direction during winding to unload said elongated conductor from the inner diameter of said shuttle magazine and wind said elongated conductor through said core hole and about said core; a hold-up means to support the inner diameter of the elongated conductor coil in the shuttle magazine and, during winding, to move outwardly relative to the imaginary center of the shuttle magazine; and a pay-off tension control means positioned adjacent the inner diameter of said conductor coil in the shuttle magazine to control the tension on the conductor as it is being wound on the core.
