  • Method for drying solvent based film
    Patent number: 5553835
    Abstract: Solvent based film is produced in an endless belt casting apparatus (10) in which, within initial compartments (46-52), flows of gas are directed through transversely elongated inlet channels (85.sub.i) to contact a layer (36') of polymer and solvent supported by an endless belt (26) and flows of gas and solvent vapors are withdrawn from the vicinity of the layer by transversely elongated gas plenums (68); within subsequent compartments (54-62), flows of gas are directed through elongated inlet plenums (74) to contact the layer and flows of gas and solvent vapors are withdrawn through transversely elongated exhaust channels (85.sub.o); within all compartments along upper and lower spans of the belt, flows of gas are directed at the inner side (30) of the belt from transversely elongated gas plenums (70) and flows of gas are withdrawn though outlets (72); and within initial compartments (46-52), flows of cooling gas are directed at the edges of the inner side of the belt from cooling nozzles (146,148).
    Type: Grant
    Filed: April 7, 1995
    Date of Patent: September 10, 1996
