Abstract

A multi-layer roll having a thin fluoropolymer top coat on an elastomeric base layer bonded to a substantially rigid insert is provided. The top coat is formed by placing a thin non-self supporting fluoropolymer sleeve about the insert, or wrapping extruded fluoropolymer film about the insert which is placed in a mold sleeve and positioned in a book mold to hold the membrane in place. Liquid or flowable elastomer is injected into the space between the insert and flexible top coat at a point downstream of where the top layer is held in position between mold elements to prevent wrinkling. The mold is then heated to cure the elastomer.
