Abstract: A method and apparatus for drying a fiber web is provided by pressing the web, preferably by impulse drying and then introducing the web into a gas pressurized zone followed by reducing the pressure in the zone, the reduction preferably being effected with cooling of the fiber web. In another embodiment, the web exiting a nip formed between press rolls is wrapped an appropriate amount about the surface of the heated roll to provide a final stage of pressurization.
