Abstract

A method for painting a component such as a motor vehicle body component includes applying to the component a base coat layer, a pattern such as a decorative strip or a graphic element, and applying a clear lacquer coat. The pattern ( 7 ) is applied to the base coat layer without interposing a clear lacquer coat. A corresponding painting facility is provided.

First claim

The invention claimed is:

1. A method of painting a component, comprising:
applying a single base coat layer onto the entire component;
applying a pattern directly onto the base coat layer previously applied to the component without the use of a mask, wherein the pattern is applied with a jet of coating agent that does not emit a coating agent mist;
applying a clear coat layer onto the component.

2. The method of claim 1 , further comprising flash-drying of the base coat layer after application of the base coat layer and before application of the pattern.

3. The method of claim 1 , further comprising intermediate drying of the base coat layer after application of the base coat layer and before application of the pattern.

4. The method of claim 1 , further comprising flash-drying of the pattern after application of the pattern and before application of the clear coat layer.

5. The method of claim 1 , further comprising intermediate drying of the pattern after application of the pattern and before application of the clear coat layer.

6. The method of claim 1 , wherein the base coat layer and the pattern are applied wet-on-wet without intermediate drying.

7. The method of claim 1 , wherein the base coat layer and the pattern and the clear coat layer are applied wet-on-wet in a 3-wet process without intermediate drying.

8. The method of claim 1 , wherein
the pattern and the clear coat layer are applied in separate paint booths.

9. The method of claim 1 , wherein
the base coat layer, the pattern and the clear coat layer are applied automatically by means of a multi-axis, freely programmable painting robot.

10. The method of claim 9 , wherein
the pattern is applied by an applicator which does not emit a coating agent mist but emits a narrowly delimited jet of coating agent.

11. The method of claim 10 , wherein
the base coat layer and the clear coat layer are applied by an atomiser.

12. The method of claim 11 , wherein
the base coat layer and the pattern and the clear coat layer consist of wet paint.
