The press roll includes a rigid inner shell and flexible, elastic outer shell which rotates around the inner shell. An outwardly pressurized elongate pressure ledge is placed in the inner shell at the nip to produce an elongated nip and to be pressurized in opposition to the associated roll at the nip. In an alternate embodiment, the pressure ledge has a pressurized, outwardly facing recess facing the outer shell. A drive roll drives the outer shell to rotate around the inner shell. Recesses in the inner shell carry lubricant for lubricating the rotation thereof. |
