Abstract:
A device for the treatment of sheet materials by means of water jets, said device comprising:a body (1) for supplying pressurized water, said body comprising a feed chamber (2) which extends over the entire length of said body and inside which the pressurized water is taken through a filter (4); a distribution region, distributing the pressurized water over an entire treatment width against a perforated plate (7) provided with microperforations, said microperforations defining water jets (8) directed against the surface of a material (S) to be treated, said material being supported by a transporter element subjected to a suction source allowing the treatment water to be removed, wherein the water is transferred from the feed chamber (2) to the perforated plate (7) via a channel (22) of rectangular cross section extending over an entire length of the plate, from the periphery of the feed chamber (2) to the surface of the perforated plate (7), a chamber between side walls (21) of this channel and a height of the channel producing a unidirectional, stable and turbulence-free flow of water.
