60%, wherein the web can be conveyed when so desired fully supported from the wiresection of the paper- or boardmaking machine up to the winder, while simultaneouslyutilizing the quality benefits obtained from a controlled reduction of the web moisturecontent and dewatering of the same. The web is conveyed supported by a transfer belt ()through at least one web surface treatment apparatus such as a coater station (S1B) or acalender prior to passing the web to the first dryer cylinder group () of the paper- orboardmaking machine. One nip () supported by a transfer belt () is suitable for

dewatering simultaneously with the application of a treatment substance to the web. Thedewatering nip () may be formed between a transfer belt () and the wire () of the wiresection or the felt () of the press section.
