Abstract
The device ( ) and method are used for ventilating an offset pocket space ( ) located in a drying section of a papermaking machine by injecting air from at least one heated dry air supply inlet ( ). The offset pocket space ( ) is situated between three axially-parallel drying cylinders ( ) over which consecutively runs a paper web ( ). A first and a third of these cylinders ( ) are vertically spaced from a second one. The paper web ( ) is pressed against the first and the third cylinder ( ) by a felt ( ) which further runs around a felt roll ( ) having a rotation axis parallel to that of the cylinders ( ). The felt roll ( ) is disposed between the three cylinders ( ) in an offset position which is closer to the first cylinder ( ) than the third cylinder ( ).
