Abstract
A method for drying a fibre web comprising passing the fibre web with at least one paper machine fabric between two bands which move in parallel. The bands have a good thermal conductivity and are impermeable to air. The fibre web and paper machine fabric are passed between the bands so that the fibre web is in contact with a first band to be heated and the paper machine fabric is in contact with a second band to be cooled. The method includes heating the first band with pressurized hot water, and cooling the band to be cooled with cooling water having substantially the same pressure and a lower temperature than the hot water.
