摘要： FABRIC BACKED POLYVINYL CHLORIDE SHEET MATERIAL IS PASSED OVER AN EMBOSSING ROLL CONTAINING THE DESIRED SURFACE PATTERN AND A PLURALITY OF SMALL STUDS THAT PRODUCE DEPRESSIONS EXTENDING THROUGH ABOUT 80-95% OF THE POLYVINYL CHLORIDE FILM THICKNESS. HEATED AIR THEN IS DIRECTED AGAINST THE SHEET MATERIAL. THE HEAT AND PRESSURE OF THE AIR COMBINE TO REMOVE THE THIN SECTIONS REMAINING AT THE BOTTOMS OF THE DEPRESSIONS AND SMOOTH THE EDGES OF THE RESULTING PERFORATIONS.
