Paint particles are applied to an object (15), such as an aluminium section, which is conveyed along a horizontal path through a spray booth (1) in which electrically charged paint particles are sprayed onto the object. The spray booth has two belt assemblies (17) which each have a belt (18) comprising an upper run (18') and a lower run (18'') merging with the upper run in a wedge-shaped point and which are arranged one on each side of the path, the point being directed at the path. The upper run (18') of the belts (18) forms the bottom of the spray booth (1). The belt assemblies (17) are set so as to form an air gap between the point and the object (15) and mark a boundary line on the object, paint particles being applied to the object on one side of the boundary line while there is no such application on the other side. Each belt (18) is driven in such a direction (P3) that its upper run (18') is moving away from the path. An exhaust means (32) is provided in the spray booth (1) to generate a negative pressure therein. |
