Patent ID: 8260592

Claim:
A method to provide a prognosis of a surface topography for a tissue paper which is to be produced in a paper manufacturing process by utilizing a specified structured fabric and into which a structure is embossed by the fabric, the method comprising the steps of: plotting a surface topography of at least one structured fabric which is already utilized in a paper production process, whereby sensor data originating from the surface topography of the already utilized structured fabric is used in the plotting; simulating a surface topography of a simulated tissue paper through data processing by a simulation of the paper production process using the plotted surface topography of the structured fabric; calibrating an algorithm used for the simulation step including a comparison of the simulated surface topography of the simulated tissue paper with a surface topography of an actual tissue paper produced with the structured fabric which is already being utilized in the paper production process; and simulating a surface topography of the tissue paper which is to be produced using a surface topography of the specified structured fabric by utilizing the calibrated algorithm in order to provide the prognosis of the surface topography of the tissue paper which is to be produced.
