  • Patent number: 5096750
    Abstract: An apparatus and a method for curtain coating of paint or varnish on objects having profiled application surfaces, such as profiled door leaves, comprising a curtain head provided with a paint/varnish inlet and return outlet. The curtain head hereby exhibits two curtain lips positioned opposite each other, as well as an upper and a lower flow-equalization rail. The curtain head is further positioned at a predetermined height over a collector channel. A return line connects the return outlet with the collector channel and a conveyor is arranged to feed the profiled object inbetween the curtain head and the collector channel when applying the paint/varnish. The invention relates specifically to that the curtain height between the lowermost edge of the curtain lips and the application surface of the profiled object is at least 250 mm, and that the distance between the upper and the lower flow-equalization rail decreases in a direction from the paint/varnish inlet to the return outlet.
