Patent

CA 2224183

The invention relates to a process for making metal wire, comprising: (A) forming metal foil (28); (B) cutting (20) said foil (28) to form at least one strand (30) of metal wire; and (C) shaping (22, 24) said strand of wire to provide said strand with desired cross-sectional shape and size. The process is particularly suitable for making copper wire, especially copper wire having a very thin diameter (e.g., about 0.0002 to about 0.02 inch).

L'invention concerne un procédé de fabrication de fil métallique. Ce procédé consiste à (A) former une feuille de métal; (B) couper cette feuille pour former au moins un toron de fil métallique; et (C) mettre en forme ce toron de fil métallique pour lui conférer la forme et la dimension de section transversale appropriées. Ce procédé est particulièrement adapté à la fabrication du fil de cuivre, en particulier, du fil de cuivre présentant un diamètre très mince (par exemple, d'environ 0,0002 à environ 0,02 pouce.)
