Abstract
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.
