ABSTRACT:
A method of drying a cardboard or a paper web by passing the wet web supported by a drying band between two moving, nonpermeable surface elements having good heat conducting properties. The surface element contacting the web is subjected to heating and the surface element contacting the drying band is subjected to cooling. Due to the heating of the web the water contained therein is caused to evaporate and the evaporated water is caused to condense into the drying band due to the cooling of the drying band. The water is removed from the drying band after the web and the drying band have left the surface elements and have been separated from each other.
