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 a heated dry air supply inlet ( ). The offset pocket space ( ) is situated between a set of three axially-parallel drying cylinders ( ) over which consecutively runs a paper web ( ). The device ( ) comprises a first air outlet ( ) where a first air stream is directed into a cleft ( ) defined where the felt ( ) rejoins the felt roll ( ), and a second air outlet ( ) where a second air stream is directed in close proximity to the felt ( ) at a location which is upstream of the cleft ( ). In use, the device ( ) and the corresponding method allow the first air stream to flow through the felt ( ) and lift the paper web ( ) away from the felt ( ) so as to reach the offset pocket space ( ). The second air stream creates an air curtain to lower the pressure in a zone between the first ( ) and the second air outlet ( ).
