METHOD OF MEASURING THE QUALITY PROPERTIES OF PAPER AND/OR BOARD ON MOVING WEBS

摘要

Detection of the thickness of a moving web, whereby optical methods are used in a contactless manner and the spectra (1) are evaluated with chemometric methods, is already known per se. According to the invention, an evaluation method (10, 20, 30) consisting of various steps is used. According to said method, various qualities of the paper or cardboard are determined in additi on to basic qualities thereof by means of multi-step modeling.
