Abstract: The invention is generally directed to techniques for reducing premature drying of solvent-based coatings, including premature drying at sites on the apparatus that applies the coatings. By introduction of solvent vapor proximate to the coating apparatus, and by passively bringing the solvent vapor to the site, the risk of premature drying is reduced. In the presence of the solvent vapor, solvent in the coating fluid tends not to evaporate quickly. The solvent vapor may be introduced by any of a variety of solvent vapor emission devices, and may be brought to the site passively by, for example, increasing the concentration of solvent vapor in a boundary layer that moves with the substrate being coated, diffusion, or natural convection.

Abstract: A system for coating a substrate with ultra-thin layers in stripes includes moving the substrate through a coating station and forming a composite layer including coating fluids and a carrier fluid. The composite layer flows at a rate that is sufficiently high to form a continuous flowing fluid bridge of composite layer to the substrate surface and to contact the substrate with the flowing composite layer to interpose the coating layers between the substrate and the carrier fluid. The carrier fluid is removed while leaving the coating fluid deposited on the substrate as a coating layer.

Abstract: A curtain coating method and apparatus using a rotatable or slidable coating plate and in which a coating liquid freely falls in the form of a thin film from a hopper. The thin film collides with a web continuously running and circumferentially turning around a backup roller to coat the web. The coating plate is rotated or slid to retract so that the freely falling coating liquid reaches the web so as to coat the web after the freely falling coating liquid flows along a checking plate which is doglegged in section and provided on a forward end of the coating plate, thereby coating the web with an even thickness at the start of coating operations.

Abstract: The dielectric layer or layers in a ceramic capacitor having at least one buried electrode is deposited by a curtain coating process that includes obtaining a measure of the ceramic-paint-curtain thickness. A source of electromagnetic radiation, e.g. in the infrared range, is directed equally near the left and right edges of the curtain, and detectors at the opposite curtain surface side pick up the difference in the radiation transmissivity which is a measure of curtain thickness assymetry left to right. By adjusting the paint reservoir from which the curtain issues to make the difference zero and the curtain symmetrical, uniformity in paint coating thickness is achieved.

Abstract: A process for the multiple coating of objects or webs which are continuously moving past a coating point, using coating apparatus according to the curtain coating process. This process is carried out such that any number of comparatively high viscosity layers is embedded between an accelerating layer which is positioned below the layers and has a viscosity range of from 1 to 20 mPas and a layer thickness of from 2 to 30 .mu.m, and a spreading layer which is positioned above the comparatively high viscosity layers and has a viscosity range of from 1 to 10 mPas and a layer thickness of from 5 to 20 .mu.m. By the curtain coating process, coating rates of 400 m/min and more may be achieved with a good coating quality.
