ABSTRACT:
A method and an apparatus for cleaning a continuous web of material (1), for instance a paper web, whereby the web of material is brought to pass through a suction chamber (2) having inlet (12) and outlet (13) for the web of material and one or more air outlets (11), for instance at the bottom thereof, which outlets are connected to a suction source. A means (4) for working the web of material (1) may be provided inside the suction chamber. The inlet (12) and the outlet (13) have substantially the same cross-section area. The amount of air entering the suction chamber through the web inlet (12) is restricted to cause a greater amount of air to flow into the suction chamber through the web outlet (13) than flows into the suction chamber through the web inlet (12).
