ABSTRACT:
A method and apparatus for continually depositing coating materials on a moving web in precise shapes or patterns. Two enclosed chambers and a rotatably mounted mask having pattern-shaped openings formed therein are provided, with the mask openings being alternately movable between each of the enclosed chambers. In one enclosed chamber, coating materials are applied through the mask openings to web materials presented thereat. In the other chamber, cleaning apparatus continuously cleans rotary mask surfaces to thereby prevent pattern-definition-degrading coating material buildup on rotary mask surfaces immediately adjacent the mask openings. Apparatus is also provided for generating and maintaining a partial vacuum within each enclosed chamber.
