Abstract
Abstract A method of manufacturing fuses in which a core wire composed of a non-conductive fibrous material is provided with a layer of thermosetting material. The thermosetting layer is set by heating, so that the core wire is rigidified. The core wire is subsequently wound with a very thin metal wire. The wound core is then cut into segments of predetermined dimensions. The segments are mounted in suitable containers, so that fuses are obtained.
