<p>A metal sheet (2) is cut along a cutting line (9) of given shape by coating the sheet (2) with a layer (6) of insulating material to define an exposed portion (8) of the same shape as the required cutting line (9); positioning the sheet (2) inside an electrolytic cell (10) having an anode and a cathode; connecting the sheet (2) to the anode; and operating a direct-current generator (25) to generate, between the anode and cathode, a potential difference such as to oxidize the metal of the sheet (2) at the exposed portion (8). <IMAGE></p> |
