Abstract
An improved contact nip roll, a method for assembling an improved contact nip roll, a system for nipping a web, and a method for nipping a web are provided. The improved contact nip roll integrates an inner softer core that can provide compliancy to web caliper variations, while rigid annular rings and a harder outer skin can maintain a uniform contact area.
