Abstract: An endless work fabric having a loop seam construction and a method of manufacture thereof is disclosed, wherein the fabric is used as a papermaker felt, a papermaker dryer fabric, a forming wire, or filter fabric. An endless belt formed of a preselected material preferably having longitudinally extending yarns included therein is collapsed upon itself to form folded ends that are stripped to expose end loops. The loops as formed in the ends of the fabric are intermeshed to define a transversely extending channel through which a pintle member is extended for joining the two ends of the folded fabric to define the endless work fabric. An alternate construction includes forming the fabric of nonwoven materials and interconnecting the ends of the collapsed fabric by a hinge-like construction through which a pintle member is extended.
