METHOD OF PRODUCING LAMENTED EMBOSSED WEBS HAVING EQUAL EMBOSSED DEFINITION ON BOTH SIDES

摘要

A method of forming a multi-ply web by embossing a first plybetween a first pair of matched embossing rolls including a firstembossing roll having protuberances formed in a substantially rigid outersurface and a second embossing roll having protuberances formed of aresilient material thereby forming raised portions and recessed portionsin the first ply, embossing a second ply between a second pair ofmatched embossing rolls including a third roll having protuberancesformed in an outer surface formed of a resilient material and a fourthroll having protuberances formed in a substantially rigid outer surfacethereby forming raised portions and recessed portions in the second plywith the first and second pairs of matched embossing rolls beingpositioned such that the first embossing roll is positioned adjacent thethird embossing roll forming a nip region between the respectiveprotuberances formed in each roll. An adhesive is then applied to theweb carried by the third adhesive roll with the first ply and second plybeing adhered to one another in the nip region wherein the raisedportions of the first and second plies are adhered to one another and therecessed portions of the first and second plies are spaced from oneanother.
