A method and device for drying and/or cooling a paper web or equivalent in which the web is passed over the circumference of a revolving roll on support of a face of a support wire that faces the roll. The web is dried and/or cooled by means of a gas blown through openings in the mantle of the roll into a space between the outer face of the roll and the web supported by the support wire, whereby a support zone formed by pressurized gas is formed between the outer face of the roll and the web. Humidified gas is passed out of the support zone into the interior of the roll through other openings in the mantle of the roll into a system of exhaust ducts placed inside the roll.
