Abstract
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.

A method for contactless application of a coating on a three dimensionally distributed surface (14;24;34;44;54;74;84;104), said method comprising
- applying 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 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 surfaces,
- wherein said electric field is applied over said surface between an electrode (11;21;31;41;51;71;101) and a means (10;20;30;40;50;60;70;80;100) for ejecting said particles,
- adjusting the relative positions of said means (10;20;30;40;50;60;70;80;100) for ejecting said particles and said surface and said electrode (11;21;31;41;51;71;101) in order to control the positions at which said particles are applied on said surface.
A device for applying a coating on a three dimensionally distributed surface (14;24;34;44;54;74;
- 84;104), said device comprising
- means (10;20;30;40;50;60;70;80;100) for ejecting electrically charged particles (15;25;35;55;65;75;85;105),
- an electrode (11;21;31;41;51;71;101) for forming an electric field (12;22;32;42;52;72;82;102) between the electrode and said means for ejecting said particles, wherein said electric field has flux lines with a longitudinal direction extending through said surface in order to guide said particles to said surface so that they form said coating, and
- means for predetermining a pattern according to which said particles are arranged to form said coating,
- wherein said means (10;20;30;40;50;60;70;80;100) is movable in relation to said electrode (11;21;31;41;51;7l;101) and said surface (14;24;34;44;54;74;84;104) in order to control the positions at which said particles are applied on said surface.
