Claim 5:
6. The method according to claim 4, wherein b) comprises:
b1) defining a second orthogonal coordinate system whose point of origin is the first point, and whose abscissa-axis, ordinate-axis and height-axis, are superimposed with the axes of the most recently-defined first orthogonal coordinate system, at a1) or a72);
b2) defining a new abscissa-axis as the abscissa-axis of the second orthogonal coordinate system;
b3) defining, in the second orthogonal coordinate system, an initial point as a point on the strip of the surface to be coated, whose abscissa is the smallest among the points of the strip;
b4) defining, in the second orthogonal coordinate system, a cut point as a point on the strip of surface, situated, in relation to the initial point and along the new abscissa-axis, at a given distance;
b5) calculating an average normal vector for a temporary portion of the defined strip of surface to be coated, defined between a third plane and a fourth plane perpendicular to the new abscissa-axis, and passing through the initial point and the cut point, respectively;
b6) calculating a temporary longitudinal axis equal to the normalized vector product of the average normal vector calculated at b5) and of the opposite of the ordinate-axis of the second orthogonal coordination system;
b7) comparing the new abscissa-axis and the temporary longitudinal axis;
b8) if the new abscissa-axis and the temporary longitudinal axis are identified as being different at b7), then:
b81) redefining the new abscissa-axis as being equal to the temporary longitudinal axis; and
b82) implementing b3) to b7) again; and

b9) if the new abscissa-axis and the temporary longitudinal axis are identified as being equal at b7), then defining a portion of the strip to be coated as equal to the temporary portion at b5).
