Method and apparatus for high-pressure water jet cutting of thick webs of soft material

摘要

The invention concerns the cutting of thick webs (2) of fibrous material, using a device comprising a base (3) to which is fixed a blade (4) carrying at its end a jet (5) which, fed with pressurized water via a duct (7, 8), emits a fine and ultra-fast jet of water (6). At each pass, a new thickness H is cut in the web (2) while the edges (12a, 12b) of the part already cut out are separated from each other by the blade (4); the jet (6), thus protected, retains its full cutting power. …IMAGE…
