ABSTRACT:
A method and apparatus for cutting a continuously moving sheet material in which a nozzle for directing a jet stream of fluid under high pressure is driven in predetermined directions along a closed track consisting of a pair of straight paths intersecting each other symmetrically at a predetermined angle relative to the cutting direction of the sheet material and a pair of curved paths connecting the associated ends of the straight paths. In the method and apparatus, the moving velocity of the jet nozzle is controlled as a function of the feeding velocity of the sheet material and the desired length of sheets cut from the sheet material, and the energy of the fluid under high pressure directed from the moving jet nozzle toward the sheet material is utilized to cut the sheet material into the sheets of desired length.
