HEATABLE, THREE-DIMENSIONAL PANE WITH SUN FILTRATION CHARACTERISTICS, METHOD AND DEVICE FOR PRODUCING, AND/OR COLOURING THREE-DIMENSIONALLY CURVED GLASS AND/OR PLASTIC PANES

摘要

The aim of the invention is to provide a method for printing decorative and functional elements on curved, i.e. convex glass panes, e.g. on heating surfaces, in different shades with a permeability to visible radiation that can be adjusted and to provide corresponding devices for carrying out said method, which do not have the disadvantages of known methods, in particular screen printing. The method for printing and/or colouring three-dimensionally curved glass and/or plastic panes is characterised in that the printed elements or application of colour that form the functional or decorative elements are applied to the three-dimensionally formed glass pane using an ink-jet method and a laser method and/or a photolithographic method and a laser method, or using sputter technology. The inventive device comprises: a loading and retrieval robot (1); a revolving mechanism (2) comprising different stations, such as a centring station (2.2), a colour application station (2.3), a decorative element baking station (2.4) etc. and coupled to a horizontal transport section (3), which likewise comprises several stations, such as a heating-field application station (3.2), a sintering station (3.3), a terminal application station comprising a measuring and evaluation station (3.4) of the total resistance etc.; and a sputtering system (5) running parallel to the horizontal transport section (3). The heatable pane (6) comprising a series of layers that exhibit excellent heating and sun filtration properties consists of a layer (7) that functions as a heating layer (7), composed of a semiconductor material and/or a metal oxide and an organic or inorganic protective layer (8) applied to the aforementioned layer. The main application area for the invention is the production of panes used in automobiles.
