The machine including a hot air hood, an upstream drying zone, a downstream dryer cylinder and a dryer hood. The upstream drying zone has an area in which the moving fibrous web is treated with hot air from the hot air hood, the hot air hood being allocated to the upstream drying zone. The downstream dryer cylinder is a Yankee-Cylinder. The dryer hood is associated with the downstream dryer cylinder for further drying of the fibrous web. The hot air for the hot air hood is at least partially recovered from the dryer hood which is associated to the downstream drying cylinder.
