Abstract
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.
