Method and apparatus for process control of mechanical embossing texturing

Abstract From the Canadian patent

Disclosed is both a method and apparatus for controlling and measuring an embossed texture on a decorative article. The embossed textured article includes both, peaks and valleys that are measured arad quantified to determine a profile of the, textured article. Typically, the textured article comprises both chemically and, mechanically embossed areas. The method uses moving average subtraction and peak/valley determinations to eliminate web flutter that often distorts the quantification of the mechanically embossed texture. The resulting profile may then, be used to control a desired embossed profile.
