Abstract: A system and a method for ventilating an offset pocket space located in a drying section of a papermaking machine, the offset pocket space being situated between three axially parallel drying cylinders over which a paper web consecutively runs, a first and a third of the drying cylinders being vertically spaced from a second of the drying cylinders, the method comprising creating a positive pressure zone between the body and the felt between the third cleft and the second cleft.

Abstract: The device (10) and method are used for ventilating an offset pocket space (12) located in a drying section of a papermaking machine by injecting air from at least one heated dry air supply inlet (11). The offset pocket space (12) is situated between three axially-parallel drying cylinders (20) over which consecutively runs a paper web (14). A first and a third of these cylinders (20) are vertically spaced from a second one. The paper web (14) is pressed against the first and the third cylinder (20) by a felt (16) which further runs around a felt roll (26) having a rotation axis parallel to that of the cylinders (20). The felt roll (26) is disposed between the three cylinders (20) in an offset position which is closer to the first cylinder (20) than the third cylinder (20).
