High pressure fluid processing device

Claim 1

A high pressure fluid processing device for removing burrs from molding plastic or processing inorganic fiber woven cloth to be used as a reinforcement material for printed circuit boards or composite material comprising: means for conveying workpieces to be processed, a frame positioned across said conveying means, a header means having a plurality of nozzles thereon positioned at intervals (P) in the transverse direction of workpieces to be processed for producing a jet flow from said nozzles in a columnar shape, said header having coupling parts being coupled to a driving means for rotation with a radius (e), means for moving said plurality of nozzles in circles at speeds ranging between 100 rpm and 3000 rpm with said radius (e) in accordance with said circular motion of said coupling parts of said header means, and means for forming a locus on the conveyed workpieces by the jet flow jetted from one of said nozzles onto the workpieces in a helical shape so as to generally uniformly apply high pressure fluid stream energy across the surface of each of the workpieces, wherein said radium (e) and said nozzle interval (P) satisfy the equation: e≧P/2.
