Abstract

See full text

A method for determining the dryness of a fibrous web, in particular a tissue web, during the production of the fibrous web, is carried out in a machine including a drying cylinder, in particular a Yankee cylinder, to which at least one, preferably two, dryer hoods are assigned, and a reel-up for winding up the fibrous web. The determination of the dryness of the fibrous web is carried out before the drying cylinder on the basis of measured values which describe the following variables: the amount of solids in the fiber web at the reel-up, the amount of water in the fiber web at the reel-up, and the amount of water which is evaporated in the dryer hood or hoods. A method for controlling or regulating a machine for producing a fibrous web, a computer program and computer program product are also provided.
