摘要
This invention relates to an apparatus and method for identifying periodic roughness variations on a paper surface. Such devices of this type, generally, collect topography data from the paper surface, analyze the data, and compare the data with known signature topographies of paper machine clothing and equipment to determine the location in the paper manufacturing process where the periodic roughness variations on the paper surface are being produced.
