    Patent number: 6511015
    Abstract: A method and a device for stabilizing the web run in a paper machine or the like having a blow suction module (12) mounted above and/or below the web. The blow suction module comprises a blow nozzle unit (14) extending across the web, through which gas, such as air or combustion gas, is blown against the web (10) from the blow nozzle unit, and a first air discharge unit (18) arranged on the front side of the blow nozzle unit, and a second air discharge unit (22) arranged on the back side of the blow nozzle unit, which remove air or gas from between the web and the blow suction module. The blow suction module is asymmetric regarding the first and second air discharge units, so that more air or gas is discharged via the first air discharge unit than via the second air discharge unit.
