Abstract

A spray applicator is disclosed. The spray applicator can include a carrier body including a number of contact surfaces and at least two nozzle bodies. Each nozzle body can be fastened on one of the contact surfaces and have a spray slit for producing a spray jet fanned out transversely to a center plane. the center planes can cross one another along a straight line. The straight line can extend outside the carrier body. The contact surfaces can face the straight line and be offset with respect to one another in the direction of the straight line.

First claim

What is claimed is:

1. A spray applicator comprising:
a carrier body comprising at least three contact surfaces, the at least three contact surfaces comprising a first contact surface, a second contact surface, and a third contact surface, the second contact surface being inclined with respect to the first contact surface by an angle α, the third contact surface being inclined with respect to the first contact surface by an angle 2α;
at least two nozzle bodies, wherein each nozzle body is fastened on one of the contact surfaces and has a spray slit for producing a spray jet fanned out transversely to a center plane, the center planes cross one another along a straight line, the straight line extends outside the carrier body, and the contact surfaces face the straight line and are offset with respect to one another in the direction of the straight line; and
at least two independent material feed channels each having a through-bore, each of the material feed channels configured to independently supply the spray slit of one of the nozzle bodies and extending through the carrier body and the contact surface of the nozzle body via the through-bore.

2. The spray applicator of claim 1 , wherein the straight line extends through at least one nozzle body of the at least two nozzle bodies.

3. The spray applicator of claim 1 , wherein the nozzle bodies are structurally identical to one another.

4. The spray applicator of claim 1 , wherein the spray jets are fanned out in jet planes parallel to one another.

5. The spray applicator of claim 1 , wherein a distance between adjacent ones of the at least two nozzle bodies measured along the straight line is less than the thickness of both of the at least two nozzle bodies measured along the straight line.

6. The spray applicator of claim 5 , wherein a length of the contact surfaces measured transversely to the straight line is greater than the thickness of at least one of the at least two nozzle bodies measured along the straight line.

7. The spray applicator of claim 1 , wherein at least one of the nozzle bodies has a shaft extending transversely to its contact surface and feet protruding from one end of the shaft transversely to the straight line and lying against the contact surface.

8. The spray applicator of claim 7 , wherein the feet have in each case a screw hole, which corresponds to a threaded bore of the carrier body.

9. The spray applicator of claim 1 , wherein a distance between mutually facing sides of two spray slits of the at least two nozzle bodies, seen along the straight line, is less than the distance between the ends of a single spray slit.

10. The spray applicator of claim 1 , wherein, seen along the straight line, the spray jets of the first and second nozzle bodies are adjacent to one another.

11. The spray applicator of claim 10 , wherein the spray jet of a third nozzle body overlaps with the spray jets of the first and second nozzle bodies.
