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.

Lamination equipment

A roller for conveying web in a resin coating environment is formed by a core having solid polymeric material layers arranged on opposite end portions of a pressure sensitive layer. Means of securing the polymeric material layer to the core is provided to prevent the polymeric material from moving axially along the core. Hence, the polymeric material layer and pressure sensitive layer are arranged on the core to form a generally uniform rotatable web transport surface for conveying web exposed to molten polyethylene resin without the web transfer surface bearing the web being attacked and wetted with the coating material.
