Transfer of the paper or board web is improved, especially for heavy grades, with regard to the open draw length, the web stretch and web drying. The drying cylinder, guide roll and endless support belt looped therearound are interposed between the press section and first cylinder drying group, which is not drivingly coupled to the first cylinder. A clothing generally looped around and operable with the first cylinder drying group contacts the endless support belt for transfer of the web.
