Fluid jet cutting knife apparatus

摘要

The cutter for processing multiple transversely cut fish section workpieces, each having flat opposing surfaces connected with a peripheral curved surface comprises a fluid jet frame with a fluid jetting knife movably supported with respect to the frame, and the knife having a nozzle that can emit a high velocity jet of fluid for cutting the fish section workpieces to be processed. The nozzle has a fluid discharge orifice. A drive simultaneously rotates the fluid jetting nozzle about a pair of selected pivots that rotate the knife about a pair of intersecting axes. A workpiece support frame is spaced from the fluid jet frame so that the fluid jet knife is positioned to cut a workpiece supported upon the workpiece frame.
