for producing a fused fabric a fluid is passed in contact with the surface of a fabric on the surface opposite that exposed to sufficient infrared radiation to fuse at least a portion of the synthetic thermoplastic fibers which comprise at least a portion of the fabric application_number US 10844079 A description again referring to fig1 an infrared heating means indicated generally by reference numeral 10 comprises four infrared heaters 10a 10b 10c and 10d although only one infrared heater is necessary to practice the invention a group of heaters can be used as shown in the drawing it has been found that the foil type electric heaters produce good results although any type infrared heater can be employed including those using gas or similar fuels instead of electricity the infrared heating means 10 is positioned adjacent to and spaced a distance from a conveying means 12 having an expanding width section 14 and an essentially constant width section 16 a conveying means having an expanding width section 14 and a constant width section 16 is frequently referred to as a tenter frame and these are often used for transporting nonwoven fabrics however most any conveying means suitable for transporting a fabric can be used whether it contains an expanding width section or not provided the fabric is transported so that the two surfaces of the fabric are unrestricted and exposed simultaneously the expanding.
