METHOD AND APPARATUS FOR PROCESS CONTROL OF MECHANICAL EMBOSSING TEXTURING

摘要

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 o f 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 m ay then be used to control a desired embossed profile.
