ABSTRACT:
A method of drying [apparatus for ] a strip of material or web, which may advantageously be performed by providing a drying apparatus including a conditioning zone immediately following but fully integrated with the [dryer] drying zone, to lower the bulk temperature of web. The web of material can be introduced to conditioned air which is substantially free of contaminants being evolved from the coating on the web. The temperature of the conditioned air is low enough to absorb heat from the web, effectively lowering the solvent evaporation rate, and can be controlled such that it is greater than the dew point of the contaminants being evolved from the web, thereby mitigating condensation that normally forms and visible vapors that form outside of the dryer enclosure. Pressure control is provided in the conditioning zone so that solvent vapors will not escape and so that ambient make-up air can be regulated as required. Gas seal between the conditioning zone and the dryer prevents hot, solvent vapor laden air from the dryer from escaping into the conditioning zone.
