ABSTRACT:
The heated laminating roll of the present invention comprises a cylindrical core having an exterior surface, an electrical resistance heating wire disposed on the exterior surface of the cylindrical core, and a silicone rubber cover disposed on the core. The silicone rubber cover provides the exterior surface of the roll. A metallic mesh is disposed within the silicone rubber cover. The metallic mesh is electrically insulated from the heating wire and is also electrically grounded. The metallic mesh layer is typically constructed of copper. The roll also may include temperature sensing devices disposed within the silicone rubber cover. The temperature sensing devices may also be disposed within the interior of the cylindrical core. The heated laminating roll provides the benefits of using an electrical resistance heater wire and additionally includes means to effectively conduct heat throughout the roll as well as providing means to safely shield the user from electrical shock.
