(57) Abstract :
The present invention relates to a gas blower device for blowing gas onto a face of a traveling strip of material, the device comprising
at least one hollow box (20) fitted with a plurality of tubular nozzles (30) pointing towards the face in question of the strip (15) of
material. In accordance with the invention, on the side facing towards the face in question of the strip (15) of material, the hollow box
(20) presents a surface (22) of profile (P) that varies in at least one given direction (D) symmetrically about a midplane (Q)
perpendicular to the plane of the strip (15), and the tubular nozzles (30) are fastened via their roots to the varying-profile surface (22)
in such a manner that their respective axes are essentially orthogonal to said varying profile at the point in question, said tubular
nozzles having respective lengths that are selected so that the outlet orifices lie in a common plane substantially parallel to the plane o
f
the strip (15).
