  • Patent number: 6481995
    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.
    Type: Grant

  • Publication number: 20010006268
    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 and about the insert, or wrapping within extruded fluoropolymer film about the insert which is placed in a mold sleeve and positioned in a book mold to holds 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.

  • Patent number: 6141873
    Abstract: A micro-compliant roll having a PTFE top layer on a silicone rubber baselayer bonded to a metallic insert is provided. The roll with PTFE top coat is heated under pressure to a temperature below the PTFE crystalline melting point and quenched to provide a compliant top layer having crystallinity of no more than about 70 percent. The PTFE top layer is applied by adhering a fibrillated PTFE membrane to a silicone rubber baselayer using a primer of a blend of silane and a polyamide resin, or wrapping the PTFE film about an insert with end spiders placed in a sleeve mold and liquid or flowable elastomer is injected into the space between the insert and PTFE membrane.
