Patent ID: 8092650

Claim:
A method for one of producing and treating a fibrous web, comprising the steps of: establishing at least one property of the fibrous web such that one of a preselected quality range is adhered to and a predefined quality value is undershot by no more than a predefined deviation, said at least one property of the fibrous web including a cross direction profile, said step of establishing further including reducing a power consumption by establishing said at least one property such that one of (a) a lowest permissible value of a quality range is reached and maintained and (b) a maximum permissible deviation is reached and maintained at least approximately on a straight line such that said cross direction profile, which has been detected, is adjusted on a zonal basis to an at least approximately constant value across substantially all of said cross direction profile, substantially along one of said lowest permissible value and said maximum permissible deviation, said power consumption including a heat energy input.
