  • Multi-layer coating apparatus, system and method
    Patent number: 4369876
    Abstract: Multi-layer coating apparatus and system for coating a substrate having a coating chamber and means for advancing the substrate in a horizontal position through the coating chamber. The coating chamber is provided with means for depositing the coating on the bottom side of the substrate as it is advanced through the chamber. Means is provided for preventing one substrate from bumping into another and for providing a predetermined spacing from the substrates as they are advanced through the coating chamber.
    Type: Grant
    Filed: November 13, 1980
    Date of Patent: January 25, 1983
    Assignee: Optical Coating Laboratory, Inc.
