  • Method for the manufacture of cleaving tiles
    Patent number: 4351788
    Abstract: A method for manufacturing cleaving split tiles from a continuous extrusion including forming a plurality of internal channels during extruding followed by the shaping of the corners and exterior surfaces of the extrusion and forming shaped vertical surfaces defining two of the tiles sides so that they blend with the other shaping of the extrusion with the formation of the vertical surfaces occurring so that the internal channels are not compressed. The extrusion is severed along a vertical groove formed when the vertical surfaces are formed with the severed portions being subsequently fired and thereafter split into tiles.
