Abstract (en)
[origin: WO2019106315A1] The invention relates to a method for producing a spray wall (26) pierced with holes (O1, O2, O3), through which the pressurized fluid product passes so as to be sprayed into fine droplets, the method comprising the following steps: a- deforming a strip of initially flat, deformable material so as to create a bulged zone, b- drilling parallel holes in the bulged zone so as to create a pierced bulged zone, c- deforming the pierced bulged zone so as to create a doubly deformed, pierced zone (Z4), at which the holes (O1, O2, O3) are divergent, and d- cutting the strip around the doubly deformed, pierced zone (Z4) while advantageously leaving a flat peripheral region (Z5) around the doubly deformed, pierced zone (Z4) so as to obtain the spray wall (26).
