Abstract: A METHOD OF PREPARING DIMENSIONALLY STABLE SOLID VENYL RESIN-BACKED CARPET TILES CHARACTERIZED BY A FIBROUS FACE, WHICH METHOD COMPRISES: LAYING THE SURFACE OF A PRECOATED TUFTED CARPET UNDER PRESSURE BETWEEN OPPISING ROLLS HAVING A FIXED ADJUSTABLE GAP THEREBETWEEN ONTO THE WET SURFACE OF A HEAVILY LOADED VINYL RESIN PLASTISOL LAYER DEPOSITED ON A RELEASE SURFACE WHILE MAINTAINING A ROLLING BANK OF A LIQUID RESINOUS MATERIAL AT THE CARPET, COOLING ING ROLLS DURING THE LAYING PROCESS, FUSING THE HEAVILY LOADED VINYL RESIN LAYER TO THE BACK OF THE CARPET, COOLING THE FUSED LAYER, STRIPPING THE FUSED LAYER FROM THE RELEASE SURFACE, AND CUTTING THE SOLID VINYL RESIN-BACKED CARPET SO PREPARED INTO CARPET TILE SECTIONS.
