Claims

1. A PROCESS OF MAKING ELASTOMERIC TERRAZZO TYPE FLOORING, COMPRISING THE STEPS OF UNIFORMLY COATING A SHEET OF TEXTILE BACKING MATERIAL WITH AN UNFUSED LIQUID PIGMENTED POLYVINYL CHLORIDE PLASTISOL, DISTRIBUTING A CHARGE OF LOOSE UNHEATED PLASTIC GRANULES OF SOLID POLYVINYL CHLORIDE COMPOUND UPON THE COATED BACKING SHEET AND ADHESIVELY EMBEDDING THEM IN SAID LIQUID PLASTISOL, FUSING THE PLASTISOL OF FIX THE POSITION OF THE OTHERWISE LOOSE GRANULES ON THE BACKING SHEET, AND THEN BY THE APPLICATION OF HEAT AND PRESSURE, MOLDING THE COMPONENTS THUS ASSEMBLED INTO A FLAT PRODUCT OF UNIFORM THICKNESS.
