Abstract (en)

[origin: US6442865B1] Drying section of a machine for producing a material web. The drying section includes a support roll with an associated impingement dryer, and at least one straight or curved section forming at least a part of a closed path between a last nip of a press section adjacent the drying section and the support roll. The support roll and the impingement dryer are arranged to guide the material web over the support roll, and, thereby, to subject the material web to at least one of hot air and hot steam impingement. The at least one straight or slightly curved section is structured and arranged to form at least one of an impingement drying section and a transfer foil section.
