This invention relates to a method for producing or treating a fibrous web, in particular a paper web or paperboard web, with which at least one property of the fibrous web, in particular a CD (cross direction) profile, such as the moisture CD profile, is established such that a preselected quality range is adhered to or a predefined quality value is undershot by no more than a predefined deviation, wherein the power consumption of the method, in particular the heat energy input, is reduced therewith by establishing at least one property such that the lowest permissible value of the quality range or the maximum permissible deviation is reached at least approximately on a straight line.

Method for producing or treating a fibrous web

Process and apparatus for monitoring the condition of a rotating belt in a paper or cardboard machine. The process includes recording data related to a condition of the belt, and creating an at least two-dimensional image of the belt condition from the recorded condition data. The image depicts a condition characteristic in a machine travel direction and a condition characteristic in a machine crosswise direction. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Process and device for monitoring the condition of a belt

Sensor and process for measuring mass of water on a sheet forming fabric. The sensor includes a microwave element positionable to couple an electromagnetic field into a stock layer to be measured, and a microwave signal generator coupled to the microwave element to generate, in the microwave element, a microwave signal having a frequency lower than a relaxation frequency of water. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
