  • Machine for drying webs, including suction and heat-contact cylinders
    Patent number: 4000035
    Abstract: A paper-making machine has a plurality of drying cylinders for removing moisture from a wet web. The drying cylinders are arranged so that some of them are located in an upper plane and are hollow and have their interior connected to a source of suction, and others are located in a lower plane and are heated to form contact heaters. An endless traveling carrier band is trained about these cylinders in such a manner that its one surface which carries the wet web faces away from the hollow cylinders as it travels about them and faces towards the heated cylinders as it travels about the latter.
