    Abstract: An electrical conductor-dielectric laminate having an elongated electrically conductive strip and a dielectric web adhesively secured to the conductive strip. The adhesive securing the conductive strip to the dielectric is spaced inwardly from the transverse edges of the dielectric web. The dielectric web has nonplanar portions between the adhesive and the transverse edges to provide a restricted width. The dielectric web has a restricted width generally equal to the width of the conductive strip and an expanded width greater than the width of the conductive strip. An electrical coil wound from the electrical conductordielectric laminate having the expanded width dielectric web serving as an electrical insulator between adjacent conductive wraps of the coil.

    Abstract: A method of manufacturing an electrical coil comprising providing an electrically conductive strip which is superposed and adhesively secured to a dielectric web having nonplanar portions intermediate the adhesive and the transverse edges of the dielectric web. Effecting transverse expansion of the dielectric web to a width greater than the conductive strip by compressing the laminated strip. An alternate laminate structure wherein some or all of the nonplanar dielectric web portions are loosely bonded to the conductive strip in such a fashion as to permit transverse expansion of the dielectric web responsive to application of a compressive force. In one form of the invention, the laminated conductive strip is wound into coil form under sufficient winding tension to cause sequential application of compressive force to successive wraps of said coil in order to transversely expand the dielectric web. The dielectric web serves to insulate edges of adjacent conductive wraps of the coil. Establishing a multiple width laminate of the conductive strip and subsequently longitudinally slitting the multiple width laminate into a number of individual laminated strips. An electrical conductor-dielectric laminate having an elongated electrically conductive strip and a dielectric web adhesively secured to the conductive strip. The adhesive securing the conductive strip to the dielectric is spaced inwardly from the transverse edges of the dielectric web. The dielectric web has nonplanar portions between the adhesive and the transverse edges to provide a restricted width. The dielectric web has a restricted width generally equal to the width of the conductive strip and an expanded width greater than the width of the conductive strip. An electrical coil wound from the electrical conductor-dielectric laminate having the expanded width dielectric web serving as an electrical insulator between adjacent conductive wraps of the coil.

    Abstract: A method of forming a laminate including providing an elongated laminate strip having a metal ply and a layer of a thermoplastic material bonded thereto with the metal ply and thermoplastic layer initially having a substantially equal width. Compressively reducing the thickness of the thermoplastic layer and simultaneously establishing transverse enlargement of the thermoplastic layer in both transverse directions to cause the thermoplastic layer to extend farther outwardly than the metal ply. The thickness reduction and transverse expansion may be effected at a laminate temperature of about 250* to 600* F. The reformed laminate may subsequently be coiled in order to establish an electrical coil having insulation between edges of adjacent wraps of the metal ply.
