An on-machine-seamable multi-axial press fabric for a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in contiguous turns, and flattened to produce first and second fabric plies joined at folds at their widthwise edges. Crosswise yarns are removed at the folds at the widthwise edges to produce unbound sections of lengthwise yarns. A seaming element having seaming loops is disposed between the first and second fabric plies at each of the folds. The seaming loops extend outwardly between the unbound sections of the lengthwise yarns from between the first and second fabric plies. The first and second fabric plies are laminated to one another by needling staple fiber batt material therethrough. The press fabric is joined into endless form during installation on a paper machine by directing a pintle through the passage formed by the interdigitation of the seaming loops.
