US 6,474,571 B2 · Device for treating sheet materials using pressurized water jets

Abstract

A mechanism for the treatment of materials by pressurized water jets includes a body (1) for supplying water under pressure which includes a feeding chamber (2) extending over the whole length of the body, and wherein water under pressure is fed to the feeding chamber through a filter (4). The body also includes a distributing zone for distributing water under pressure over a whole treatment length against a plate (7) provided with micro-perforations which define water needles (8) directed against the surface (S) of the material to be treated. The material is supported by a carriage element subjected to a suction source eliminating the treatment water. Further, water transfer from the intake chamber (2) to the perforated plate (7), is done through a channel (22) with a rectangular cross-section extending over the whole length of the injector, from the periphery of the feeding chamber (2) up to the surface or the perforated plate (7), wherein the spacing between the side walls (21) of the channel and the height thereof produces a unidirectional and stable stream of water without turbulence.

Dependent claims

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.
