(54) Felt with seam for paper manufacture


(57) In a seam felt for paper manufacture, seam loops formed at opposite ends of a length of ground fabric to which layers of batt fiber are integrated by needle punching, are formed as groups of loops composed of machine direction yarns. When the opposite ends of the ground fabric are brought together, the groups of loops are intermeshed in an alternating arrangement to form a common bore for receiving a seam thread by which the intermeshed groups of loops are secured together. The loops of each group can be held together by adhesive bonding, or by heat adhesion if the machine direction yarns are core-in-sheath composite fibers wherein the sheath has a lower melting point than that of the core.
