ABSTRACT:
A laminated amorphous metal strip has a first layer having at least two side-by-side strips of amorphous metal of unequal widths. A second layer has at least two side-by-side strips of amorphous metal of unequal widths, the layers being in reverse order with respect to the widths of the strips such that the wider strips overlap and form a brickwork cross-section pattern. A flexible polymeric bonding material is disposed between the layers. The polymeric bonding material is an adhesive and has excellent electrical properties. A device for forming the laminated strip of amorphous metal has a plurality of rolls of amorphous metal. Strips from a roll are positioned side-by-side with strips from a wider roll. A bonding material is applied from spray guns to the surface of the strips. Strips from a roll of metal and a wide roll of metal are positioned on the bonding material in a reverse order of the wider strips. Pressure is applied to the laminate. The laminate is advanced by a continuous belt to which the laminate is magnetically coupled. The device includes a means for cutting the laminate to a desired length. A method for fabricating a laminated strip of amorphous metal includes providing the rolls of metal, positioning the strips having differing widths, applying the bonding material, applying pressure advancing the laminate and cutting the laminate.
