  • Patent number: 6120569
    Abstract: A method for production of stone pattern processing mills including the steps of application of compression to resin, cellulose, and milling material in a mold module. The resin and milling material are combined to form milling granules to be bound to the cellulose substances so as to form a milling grain cellulose layer. The backside of the milling grain cellulose layer is covered with suitable flexible substances to form a hollow-set machine/grind cushion meant for coupling with a mill chassis for use. Alternatively, the backside of the machine/grind cushion may be filled with flexible or hard material so as to form a one-piece mill.
