THE METHOD OF MAKING AN EMBOSSING ROLLER FOR EMBOSSING THERMOPLASTIC SHEET MATERIAL TO REPRODUCE THE SURFACE TEXTURE OF A POROUS FABRIC, COMPRISING THE STEPS OF; SIZING THE FABRIC WHICH HAS THE SURFACE TO BE REPRODUCED CURING THE SIZED FABRIC, ADHERING SAID FABRIC UPON THE INNER SURFACE OF A PERVIOUS HOLLOW CYLINDER, WITH THE OPPOSITE ENDS OF SAID FABRIC BUTTED TOGETHER TO FORM A CONTINUOUS CASTING PATTERN, INSERTING INTO SAID CYLINDER IN CONTACT WITH SAID FABRIC A TUBE OF POLYETHYLENE HAVING A WALL THICKNESS OF APPROXIMATELY ONE ANDD ONE-HALF MILL, SUBJECTING THE OUTSIDE OF SAID CYLINDER TO A NEGATIVE PRESSURE TO BRING THE POLYETHYLENE INTO DIRECT AND INITMATE SURFACE CONTACT WITH THE FABRIC TO ACHIEVE A CYLINDER ASSEMBLY, HEATING SAID CYLINDER ASSEMBLY TO BETWEEN ABOUT 180*F. AND ABOUT 230*F. WHILE BEING SUBJECTED TO SAID NEGATIVE PRESSURE AT WHICH TEMPERATURE SAID POLYTHYLENE IS SUFFICIENTLY SOFTENED TO MOLD ITSELF INTIMATELY AGAINST SAID FABRIC, COOLING THE CYLINDER ASSEMBLY WHILE SAID NEGATIVE PRESSURE IS MAINTAINED, INSERTING CONCENTRICALLY INTO SAID CYLINDER ASSEMBLY A DEMOUNTABLE INNER SHELL THE OUTSIDE DIAMETER OF WHICH IS SOMEWHAT LESS THAN THE INNER DIAMETER OF
