ABSTRACT:
A web coating process and apparatus employing a coating applicator, dryer or curing station and web-handling equipment for conveying the web past the coating applicator and through the dryer. The web is enclosed from at least the coating applicator to the dryer or curing station in a close-coupled enclosure or series of close-coupled enclosures supplied with one or more streams of conditioned gas flowing at a rate sufficient to reduce materially the particle count or change materially a physical property of interest in a close-coupled enclosure.
