Abstract
Equipment for laminating webs has a pressure sensitive roller formed of a polymeric material layer resistant to wetting by molten polyethylene resin. A web transport surface for conveying the web during lamination is formed by the pressure sensitive layer and abutting solid, relatively thick polymeric material layers, preferably Teflon, which is secured against movement about the core and urged into substantial uniformity with the pressure sensitive layer by a locking ring assembly.
