Abstract:
A method for stabilizing a web in a paper handling machine, comprising the steps of:mounting a blow suction module to extend across the web; blowing gas through at least one gap nozzle extending across the web in a blow nozzle unit which forms a part of the blow suction module; removing gas from between the web and the blow suction module at a first rate through a first suction nozzle extending across the web, the first suction nozzle being part of a first gas discharge unit, the first gas discharge unit extending across the web and arranged on the front side of the blow nozzle unit, as seen in the travel direction of the web; and removing gas from between the web and the blow suction module at a second rate, which is less than the first rate, through a second suction nozzle extending across the web, the second suction nozzle being part of a second gas discharge unit, the second gas discharge unit extending across the web, and arranged on the back side of the blow nozzle unit, as seen in the travel direction of the web, in order to stabilize the web run and optimize runnability of the web.
