1. An applicator head for a vacuum coating system for applying a coating to a workpiece, the applicator head comprising:
a first applicator manifold comprising:
a first manifold plate including a first manifold aperture fluidically coupled to a first conduit; and a second manifold plate affixed to the first manifold plate, wherein a first applicator channel is formed between the first and second manifold plates, wherein the first applicator channel is fluidically coupled to the first manifold aperture and forms a first applicator port at a first leading edge of the first applicator manifold, and the first leading edge is configured to be complementary in shape to an edge of a workpiece; a second applicator manifold comprising:
a third manifold plate including a second manifold aperture fluidically coupled to a second conduit; anda fourth manifold plate affixed to the third manifold plate, wherein a second applicator channel is formed between the third and fourth manifold plates, wherein the second applicator channel is fluidically coupled to the second manifold aperture and forms a second applicator port at a second leading edge of the second applicator manifold, the second leading edge is configured to be complementary in shape to the edge of the workpiece, and the fourth manifold plate has a greater width than the third manifold plate at the second leading edge adjacent the second applicator port; and a first face plate and a second face plate, each of the first and second face plates disposed over the first and second leading edges of the first and second applicator manifolds, thereby covering at least a portion of each of the first and second applicator ports. |
