Abstract of the Disclosure A belt structure including a carrier formed from a plurality of intermeshing spiral coils with adjacent coils interconnected by hinge yarns. The spiral coil carrier is placed under tension and heated to cause the spiral coils to extend longitudinally to define spaced upper and lower substantially flat surfaces. A yieldable, porous batt of synthetic fibrous material is needled into and onto one surface of the carrier. As an alternative structure, a yieldable, porous, open cell foam is applied to the spiral coil carrier to fill the interior thereof, and to extend outwardly from one surface to form an outer foam layer. The belts are particularly suitable as pressure and transporting belts in a corrugating machine, but can also be used in wet press and dryer sections of papermaking machines. 8120c -29-
