  • Board-supporting assembly for fluid jet cutting system
    Patent number: 4949610
    Abstract: A platen assembly is described for supporting a master board of material to be cut by a fluid jet cutting device. The platen assembly comprises a layer of resiliently compressible material bonded to a lattice-like network of relatively uncuttable structural material. The resiliently compressible material is adapted to be compressed by the contacting topography of the supported master board to act as a cushion, as well as to anchor the master board against movement. The lattice-like network of relatively uncuttable structurable material prevents the compressible material on opposite sides of a cut from migrating towards the cut.
