| 摘要 |
The invention relates to a method for processing a plastic substrate consisting of a step in which a partial surface is masked against coatings. Prior to the application of a coating (4) to the substrate, specific parts of the surface thereof are covered with the aid of removable masking, which at least temporarily adheres to the substrate. According to the invention, the masking is made of a liquid forming a film or a melt, acting as a film or body when applied to said partial surfaces of the substrate to which other materials are applied adhesively in other machining steps. The liquid forming a film or the melt is adapted to the material or material of the substrate in such a way that the masking (3) can be removed after the substrate (1) has been coated, without leaving any residues and without detracting from the adherence of the masked surface before that substrate is supplied for further processing. According to the invention, said further processing involves other materials (assembly profile 5, trace of adhesive 6) being applied to the surfaces that had been kept free of the coating (4) by means of the masking with adhesive connection to the substrate. |
