METHOD AND APPARATUS FOR EMBOSSING WEB MATERIAL USING AN EMBOSSING SURFACE WITH OFF-CENTERED SHOULDERS

摘要

Webs can be embossed using matched embossing elements with shoulders located off-centered. Such a configuration increases the bulk of the web and maintains the web's strength. The shoulder of one roll is located above or below the embossing surface mid-plane. The shoulder of the second roll substantially matches the off-centered elements of the first roll.
