摘要： A toroidal yoke having a modified core which contains projecting slewing points whereby the separate and distinct coils of the yoke can be wound as a single coil, thus eliminating the need for stopping the winding machine periodicaly during manufacture. The single coil is after formed into a plurality of separate coils by cutting the wire in the proper locations.

摘要： Projecting points on a yoke core are utilized to permit the winding of a number of separate and distinct coils as a single coil capable of subsequent separation into said separate coils. After the winding of a first coil the wire is snubbed against a first of such projecting points and the winding operation is stopped. The yoke core, however, is continuously rotated, dragging the wire across the yoke core until a second projecting point is reached, at which time the winding of a second coil is commenced.
