Abstract Of The Disclosure A seamed papermaking fabric having a multilayer base fabric includes an endless woven fabric forming a tubular belt that is flattened to form a base fabric with at least one helical coil Reaming member inserted between opposing sidewall portions at each respective lengthwise extremity of the base fabric. The helical axes of the seaming members extend transverse to the lengthwise direction of the fabric and the coils of the seaming member extend through space between adjacent machine direction yarns and supportably engage the machine direction yarns. The opposed lengthwise extremities of the base fabric are joined together by interengagement of the coils of the respective seaming members and insertion of the pintle member axially through the interengaged coils to form a seamed endless fabric of substantially twice the predetermined thickness.
