METHOD AND APPARATUS FOR APPLYING THIN FLUID COATING STRIPES

A SYSTEM FOR COATING A SUBSTRATE WITH ULTRA-THIN LAYERS IN STRIPES INCLUDES MOVING THE SUBSTRATE (32) THROUGH A COATING STATION AND FORMING A COMPOSITE LAYER (48) INCLUDING COATING FLUIDS (244, 248) AND A CARRIER FLUID (252). THE COMPOSITE LAYER (48) FLOWS AT A RATE THAT IS SUFFICIENTLY HIGH TO FORM...

Zusammenfassung:	A SYSTEM FOR COATING A SUBSTRATE WITH ULTRA-THIN LAYERS IN STRIPES INCLUDES MOVING THE SUBSTRATE (32) THROUGH A COATING STATION AND FORMING A COMPOSITE LAYER (48) INCLUDING COATING FLUIDS (244, 248) AND A CARRIER FLUID (252). THE COMPOSITE LAYER (48) FLOWS AT A RATE THAT IS SUFFICIENTLY HIGH TO FORM A CONTINOUS FLOWING FLUID BRIDGE OF COMPOSITE LAYER TO THE SUBSTRATE SURFACE AND TO CONTACT THE SUBSTRATE (32) WITH THE FLOWING COMPOSITE LAYER TO INTERPOSE THE COATING LAYERS BETWEEN THE SUBSTRATE AND THE CARRIER FLUID. THE CARRIER FLUID (36) IS REMOVED WHILE LEAVING THE COATING FLUID DEPOSITED ON THE SUBSTRATE AS A COATING LAYER.
