Abstract
A method for drying a fibrous web, especially a paper, cardboard or tissue web, the moving web is treated with hot air from a hot air hood in the area of a upstream pre-defined drying zone, and is subsequent carried to the drying zone in a downstream drying cylinder, especially a Yankee-Cylinder, to which an additional hood is allocated and in whose area the fibrous web is dried further. The hot air for the hot air hood allocated to the upstream drying zone is recovered, at least partially, from the exhaust air of the hood allocated to the downstream drying cylinder.
