ABSTRACT:
This invention relates generally to a dryer fabric belt used in the dryer section of a papermaking machine. The dryer fabric belt is subjected to tension forces in a machine direction by a stretch roll over which the belt travels, and is substantially free from tension forces in the cross-machine direction. The dryer fabric belt includes a plurality of hinge yarns, each extending in the machine direction continuously throughout the length of the dryer fabric. A plurality of spring coils are disposed in a common plane in a side by side relationship. Each of the coils extends in the machine direction. Adjacent coils of the spring coils are intermeshed and held together in intermeshing relationship by at least one of the hinge yarns.
