A method for the production of from spiral fashion wound strips of predetermined width of an insulating material layer having provided thereon a conductive material existing flat coils detected

摘要

This invention provides a method of fabricating thin plate like coils of high winding density, in which a coil material formed by providing a number of parallel conductors in the form of stripes on an electrical insulating layer is lengthwise cut between the parallel conductors while winding the conductors on winding means.
