THE METHOD OF MAKING A FIBROUS ABRASIVE MATERIAL COMPRISES EXTRUDING A FIBER-FORMING ELASTOMERIC COMPOSITION CONTAINING ABRASIVE PARTICLES THROUGH A MULTIPLICITY OF ARIFICES INTO A LIQUID COAGULATING MEDIUM TO FORM A MULTIPLICITY OF CONTINUOUS FIBERS, DEPOSITING SAID FIBERS WHILE STILL IN A TACKY CONDITION IN A RANDOM OVERLAPPING FASHION UPON A MOVING SURFACE TO WHICH SAID FIBERS WILL NOT ADHERE TO THUS FORM A POROUS WEB OF BONDED TOGETHER FIBERS EACH OF WHICH CONTAINS ABRASIVE PARTICLES EMBEDDED THEREIN, CURING SAID POROUS WEB, AND STRIPPING SAID WEB FROM THE MOVING SURFACE.
