A method and a device for contactless application of a coating on a three dimensionally distributed surface ( 14;24;34;44;54;74;84;104 ). The method comprises application of electrically charged particles ( 15;25;35;55;65;75;85;105 ) in such positions on said surface as to form a predetermined pattern, by guiding each of said particles individually to a predetermined position on said surface. The guiding is made by means of an adjustable electric field ( 12;22;32;42;52;72;82;102 ) having flux lines with a longitudinal direction extending through said surface, whereby said particles form said coating according to said predetermined pattern on said surface. |
