Abstract
The novel tissue products of the present invention are generally produced by calendering a tissue basesheet using at least one patterned roll. In one embodiment the patterned roll replaces the flat steel roll commonly used in calendering. The elements on the patterned roll provide a means of providing a nip having variable loading such that Z-direction variability in the web is reduced, yielding a smoother web, but without subjecting the web to excessive compression forces and preventing excessive caliper loss. Thus, webs converted according to the present invention tend to retain a greater percentage of their caliper and bulk when converted compared to webs converted using conventional calendering means.
