Abstract
Abstract A BOTTOM CARRIER SHEET OF MATERIAL HAVING MEMORY IS PASSED OVER A ROLL HAVING DEPRESSIONS THEREIN, AND A CURABLE RESIN UNDER PRESSURE FORCES THE SHEET INTO THE DEPRESSION AND FILLS THE DEPRESSIONS IN THE SHEET MATERIAL. EXCESS RESIN IS SCRAPED FROM THE SHEET LEAVING THE RESIN WHICH FILLS THE DEPRESSIONS IN PLACE. THE SHEET IS THEN REMOVED FROM THE ROLL AND CAUSED TO ASSUME A FLAT CONDITION TO MOVE THE RESIN UP OF THE DEPRESSIONS AND PROVIDE RAISED INDICIA OF THE CONFIGURATION OF THE DEPRESSIONS. INDICIA OF DIFFERENT COLORS CAN BE ADDED IN LIKE MANNER, AND FINALLY A FILM OF RESIN IS COVERED BY A TOP SHEET RAISED INDICA. THE FILM OF RESIN IS COVERED BY A TOP SHEET OF SEPARATION MATERIAL AND THE COMPOSITE SANDWICH OF RESIN AND TOP AND BOTTOM SEPARATION SHEETS ARE ROLLED INTO A PACKAGE AND CURED TO PRODUCE A SHEET MOLDING COMPOUND.
