ABSTRACT:
An apparatus for processing a self-supporting web includes a rotatable mandrel and a stationary block member which defines a recess adjacent the mandrel. The recess is shaped to form a converging chamber between the mandrel and the block member, which converges in the direction of motion of the self-supporting web. A belt is mounted for movement through the chamber and is positioned between the self-supporting web and the block member. The chamber is sized to compress the self-supporting web between the block member and the mandrel, thereby reducing the thickness of the self-supporting web as it passes through the chamber. This apparatus can be used for laminating, liquid removal, or caliper reduction operations on the self-supporting web.
