A method is described which is characterised in that copper foils are twice-coated with meltable coating means in such a way that the copper foil (19) is guided approximately half encirclingly about a heatable roll (1), and coated by means of two heatable roll-type coating units (2, 4 & 3, 5) in such a way that in a first coating operation, there is applied from the melt an ultravioletly and thermally hardenable solvent-free coating means and in a second coating operation, a solvent-free, only thermally hardenable, meltable coating means is applied over the first coating means, and in that the first binding agent layer is cross-linked by radiation by ultraviolet radiators disposed downstream. There is furthermore described an apparatus for execution of the method. |
