Abstract
An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto. The resulting endless base fabric layer is flattened to produce first and second fabric plies joined to one another at folds at their widthwise edges. Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce unbound sections of lengthwise yarns. An on-machine-seamable base fabric, having seaming loops along its widthwise edges, is disposed between the first and second fabric plies of the flattened base fabric layer. The seaming loops extend outwardly between the unbound sections of the lengthwise yarns from between the first and second fabric plies. The first fabric ply, the on-machine-seamable base fabric and the second fabric ply 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 at its two widthwise edges.
