A method and apparatus for impingement of fluid onto a moving surface. The apparatus (40) includes an asymmetric slot nozzle (50) having an opening (56) formed between an upstream wall (58) and a downstream wall (59). The nozzle (50) is disposed generally adjacent the surface (26) onto which the fluid is to be impinged forming an impingement distance between each of the walls of the nozzle and the surface. The impingement distance (60) of the upstream wall (58) is greater than the impingement distance (62) of the downstream wall (59) such that at least a portion of the fluid is delivered through the nozzle (50) in a direction that is counter to the machine direction (MB).
L'invention concerne un procédé et un appareil permettant de précipiter un fluide sur une surface mobile. L'appareil (40) comporte une buse (50) en fente asymétrique ayant une ouverture (56) formée entre une paroi en amont (58) et une paroi en aval (59). La buse (50) est disposée généralement contiguë à la surface (26) sur laquelle le fluide doit être précipité pour former une distance d'impact entre chaque paroi de la buse et la surface. La distance d'impact (60) de la paroi en amont (58) est supérieure à la distance d'impact (62) de la paroi en aval (59) de manière qu'au moins une partie du fluide est distribuée par la buse (50) dans une direction opposée à la direction de la machine (MD).
