The invention relates to a method of and an apparatus for drying a fiber web, whereby the fiber web (5) is dried in a cylinder drying unit (12) and in a band drier unit (11). The cylinder drying unit (12) and the band drier unit (11) are arranged one above the other. A considerable space saving is then achieved and the building costs remain rather moderate. Simultaneously, a remarkable addition to the drying capacity is achievable by moderate investments by means of existing apparatuses, for instance. (FIG. 1)
