ABSTRACT:
An improved drying system for drying coating fluids is provided by which conventional drying times are greatly reduced by subjecting the coating on a moving support web to a corona discharge in a manner creating a drying current flow along the length of the coating. Further reductions in drying time are realized by subjecting the coating to an intense electrostatic field, air streams and/or heat from a heated platen.
