Abstract (en)
[origin: WO8604549A1] The fabrication comprises the regular punching of a sheet and covering the sheet with a thin layer so as to close the perforations of the sheet. According to the desired pattern, material of the covering layer is removed from the perforations. To this effect, the sheet is spread and, at the desired locations, it is subjected to a laser beam which frees the perforations of the sheet.
