ABSTRACT:
A method and apparatus for cutting up thick layers of fibrous material, the apparatus comprising a base to which a blade is fixed. The end of the blade carries a nozzle which emits an ultrafast fine water jet when fed with water under pressure via a duct. On each cutting pass, an additional thickness (H) of the layer is cut while the flanks of the cut that has already been made are held apart from each other by the blade, thereby ensuring that the jet is not disturbed by the flanks and retains its full cutting power.
