A method of seaming an on-machine-seamable multiaxial papermaker~s fabric to prevent yarn migration. The multiaxial fabric (22) is in the form of an endless loop flattened into two layers (40, 42) along fold lines (38). CD yarns (28) are removed from the folds (38) to create extended ravel areas. This leaves the MD yarns (26) unbound in the ravel areas. Seam loops (56) are then formed from the unbound MD yarns (26) at the folds (38). CD materials (82, 84) (e.g. continuous CD yarns) are affixed to (rewoven into) the fabric along the edges of the ravel area at each fold (38). The affixed CD materials bind the CD yarn tails along the edges of the ravel areas to prevent migration of CD yarn tails into the seam area.

Méthode pour assembler une toile synthétique multiaxiale sur une machine permettant d~éviter la migration des fils textiles. La toile multiaxiale (22) a la forme d~une boucle sans fin pressée en deux couches (40, 42) le long de deux lignes de pliage (38). Les fils CD (continu/discontinu) (28) sont retirés des plis (38) pour créer des zones d~effilochage étendues. Cela laisse les fils MD (26) non reliés dans les plis. Des boucles assemblées (56) sont ainsi formées à partir des fils MD non reliés (26) au niveau des plis. Des matériaux CD (82, 84) (par ex. des fils CD continus) sont attachés (retissés) à la toile synthétique le long des extrémités de la zone d~effilochage à chaque pli (38). Les matériaux CD fixés lient les queues de fil le long des extrémités des zones d'effilochage pour éviter la migration des queues de fil CD dans la zone d~assemblage.
