Abstract
Embossing a web between unmatched male and female embossing elements, wherein the sidewall slope of the female element is different than the sidewall slope of the male element, provides an embossed web having markedly improved embossing pattern definition and, in the case of roll products, greater roll bulk at equivalent roll firmness. The unmatched male and female embossing elements are preferably made by laser engraving rubber embossing rolls.
Claims13
A method for embossing a web comprising deflecting the web between a plurality of engaging unmatched male and female embossing elements having sidewalls sloped at an angle to the plane of the undeflected web during embossing, wherein the sidewall slope of the female embossing elements is different than the sidewall slope of the male embossing elements with which the female embossing elements are engaged.
A method of embossing a tissue web comprising deflecting the tissue web between a plurality of engaging unmatched, laser-engraved, rubber or plastic male and female embossing elements having sidewalls sloped at an angle to the plane of the undeflected tissue web during embossing, wherein the sidewall slope of the female embossing elements is different than the sidewall slope of the male embossing elements with which the female embossing elements are engaged, and wherein the bulk of the tissue web is increased.
