Coil coating process

The invention relates to a coil coating process for multilayer coating of a continuous metal strip (3) which is located in the strip passage, wherein on a flat side (4) of the metal strip (3) a curable polymer primer (9) is applied and cured with the aid of a roller application in order to form an electrically insulating primer coat (10) and onto this primer coat (10) a curable polymer varnish (11) is applied and cured with the aid of a roller application in order to form an electrically insulating varnish layer (12), wherein at least one at least electrically conductive track (15) is printed at least in some areas between the primer coat (10) and the varnish coat (12). In order to increase the reproducibility of the coil coating process, according to the invention the conductive track (15) is printed in some areas on the pre-cured primer coat (10) and the conductive track (15) and the varnish (11) are applied by a wet-on-wet process.
