Abstract: A method for producing a heating system on a 3D plastic window, such as a car window. The heating system having an electric heat conductor structure with at least two bus bars and a grid line pattern with a plurality of grid lines. The method having: a step in which the two bus bars, made of a first electrically conductive paste are screen-printed onto the window by a displaceable squeegee; a step in which the grid line pattern is applied onto the window such that it respectively overlaps the two bus bars with at least one second electrically conductive paste which has a greater electrical resistance than the first electrically conductive paste, and a final step in which the two bus bars and the grid lines overlapping these bus bars are at the respective overlapping points electrically connected into the electric heat conductor structure by means of electrical connectors.

Abstract: According to an example aspect of the invention, there is provided a method for producing a heating system on a 3D plastic window such as a car window of plastic, comprising an electric heat conductor structure consisting of at least two bus bars (principal heat conductors) and a grid line pattern with a plurality of grid lines (branch heat conductors), comprising a step, in which the two bus bars are respectively screen-printed onto the 3D plastic window, preferably on the edges of the latter, by means of at least one displaceable squeegee with screen-printing ink in the form of a first electrically conductive paste, preferably a first silver paste, a step, in which the grid line pattern is applied onto the 3D plastic window such that it respectively overlaps the two bus bars with at least one second electrically conductive paste, preferably a second silver paste, which has a greater electrical resistance than the first electrically conductive paste, and a final step, in which the two bus bars and the grid

Abstract: The invention relates to a device for the pre- and/or aftertreatment of a component surface by means of a plasma jet, particularly by means of a jet of an atmospheric plasma, with a plasma head (1) forming a plasma generator with voltage and carrier-gas supply, to which plasma head a nozzle tube (8) of a plasma nozzle (7) is connected, which plasma nozzle encompasses a plasma electrode (17) of the plasma generator, which is electrically insulated with respect to the plasma nozzle, and is connected in terms of flow technology to a working gas channel (19) and has a nozzle head (11) with an outlet opening (12) for the plasma jet at its end (9) opposite to the plasma head (1), wherein the tip (18) of the plasma electrode (17) is arranged set back in the direction of the longitudinal axis (13) of the plasma nozzle (7) with respect to the outlet opening (12) of the nozzle head (11).
