Abstract:
An apparatus for processing a moving fibrous web in a paper machine comprising:a first device for processing a fibrous web;a second device for processing a fibrous web positioned downstream of said first processing device, said first and second devices defining a unidirectional path of travel for a fibrous web therebetween; andan air foil extending, between said first and second devices,said air foil including a substantially continuous web support surface extending substantially the entire distance of the path of travel between said first and second devices and a defining a first air supply channel extending across the web support surface in a direction generally perpendicular to said unidirectional path of travel, and a second air supply channel located downstream of said first air supply channel and extending across the web support surface in a direction generally perpendicular to said unidirectional path of travel, andsaid first and second air supply channels each being, adapted to provide a flow of air in the direction of the unidirectional path of travel, so as to provide a layer of air having a reduced static pressure along said substantially continuous web support surface.
