Abstract (en)
[origin: US6668436B2] A device for treating sheet-like material using water jets/needles. The device comprises a pressurize water supply body consisting of a feed chamber extending along the entire length of the body and inside which pressurized water is guided through a filter, and a distribution area distributing pressurized water along the entire length of treatment. The distribution area includes a plate (7) which is provided with microperforations, whereby the holes thereof define water needles which are directed against the surface of the material which is to be treated. The invention is characterized in that the microperforations (15) are provided inside inserts (13) which are made of a hard material. The inserts are set inside pre-made hoes (12) in the plate.
