Belt

Abstract

A belt assembly is provided for use as an endless belt traveling relative to a frame structure. The belt assembly comprises a first plain woven fabric layer having an inner surface and an outer surface that at least partially forms an upper surface of the belt. The first fabric layer includes synthetic yarns having a denier of at least about 1000. A second lofty woven fabric layer has an inner surface and an outer surface that at least partially forms a bottom surface of the belt. The second fabric layer includes an effective amount of textured synthetic yarns and/or synthetic staple filament yarns. An adhesive composition comprising an elastomeric material is adhered to the inner surface of the first fabric layer and the inner surface of the second fabric layer for joining the fabric layers.
