Abstract (en)
A method for producing electric heating elements (1) comprising a substrate (2, 2a) provided with one or more electrically conductive elements (3) that heat said substrate (2, 2a) when the electrically conductive elements (3) are crossed by an electric current, the method comprising a first step in which the electrically conductive elements (3) are applied to the substrate (2, 2a), a second step in which the electrically conductive elements (3) are sintered, a third step in which at least one dielectric protective layer (4) is laid on the sintered electrically conductive elements (3), and a fourth step in which the dielectric protective layer (4) is polymerized. In particular, the electrically conductive elements (3) comprise an electrically conductive substance that is laid on the substrate (2, 2a) by means of dispensing means (6) that are associated with movement means moving the dispensing means (6) according to two or more directions with respect to said substrate (2, 2a) to configure the electrically conductive elements (3) according to a geometry with one or more continuous strips (8).
