Abstract:
An apparatus for fabricating a multi-layer roll with a fluoropolymer top coat formed from a fluoropolymer membrane on an elastomeric base layer bonded to a substantially rigid cylindrical core, comprising:a mold having a cylindrical mold cavity having an inlet and an outlet for receiving a cylindrical mold sleeve; a cylindrical mold sleeve and spider elements for mounting on the ends of the core and extending beyond the ends of the mold sleeve to form a roll assembly and when inserted into the mold sleeve adapted to seat within the cylindrical cavity of the mold; the spider elements mounted on at least one end of the core for directing injected flowable elastomer material into the roll assembly between the core and top coat membrane positioned in the mold sleeve; the cylindrical mold cavity including a region for engaging the top coat membrane between the spider elements and the mold when the mold sleeve is placed in the mold; a source of elastomeric material for injection into the roll assembly; and means for heating the mold to cure the elastomeric material.
