Abstract
A machine for producing a fibrous web, in particular a paper web, paperboard web or tissue web, includes a former on which the fibrous web is formed on a structured belt and is dewatered between said structured belt and a forming belt, and a drying apparatus for the further dewatering of the fibrous web, through which the fibrous web is guided together with the structured belt and in which hot air flows through the permeable structured belt and the fibrous web. The forming fabric is formed by a printed forming fabric or a DSP fabric with zonally different permeability.
