  • Publication number: 20100206505
    Abstract: A machine and process for production of wet formed fibrous webs, in which the web is formed from a suspension on a fabric and subjected to a final drying process such as a Yankee dryer roll, while further subjecting the Web to an intermediate drying on a high-heat-transfer roll, with or without hood, before the final drying process. The intermediate dryer roll has a solid, gas-impermeable surface, and a localized heat source directly heats the dryer to a higher temperature than in the final drying process.
