A bridge (70) for a papermaking apparatus having a headbox (12), an apron lip (42) and a forming surface (16). The bridge spans a gap between the apron lip of the headbox and the forming surface to substantially eliminate a free jet of stock slurry as it leaves the headbox apron lip. This serves to maintain pressure from the headbox to the forming zone above the forming surface thereby eliminating the reduction in velocity of the stock slurry in the forming zone. In an aspect of the invention, the bridge generates micro- turbulent flow of stock slurry within the forming zone.

L'invention concerne un pont (70) destiné à un appareil de formage du papier, qui est composé d'une caisse de tête (12), d'un bord (42) de tablier et d'une surface de formage. Le pont enjambe un espace entre le bord de tablier de la caisse de tête et la surface de formage (16), ce qui empêche sensiblement la formation d'un jet libre de suspension de pâte au moment où cette dernière sort de la caisse de tête. Ainsi, la pression de la tête à la zone de formage est maintenue et la réduction de la vitesse de la suspension de pâte dans la zone de formage est supprimée. Selon un mode de réalisation particulier, le pont libère un flux à micro turbulence de suspension de pâte dans la zone de formage.
