A multi-layer woven papermaker~s fabric having at least two sets of seam loops. Longer and a shorter seam attachment mechanisms (220a, 220b, 220c, 220d) are used to connect the bottom and top layer seam loops. The longer attachment mechanism (220a) in the top layer (216a) being over the shorter attachment mechanism (220c) in the bottom (layer216b); and vice versa. A pintle or installation cable (222) is positioned between each set of connectors to form a seam. The pair of connectors for each set of seam loops comprises different lengths in the MD direction such that the pintle or installation cables on adjacent layers are offset in the MD direction.
La présente invention concerne un textile feutré tissé multicouche présentant au moins deux ensembles de boucles de couture. Un mécanisme de fixation de couture long et un mécanisme de fixation de couture court (220a, 220b, 220c, 220d) sont utilisés pour connecter les boucles de couture de couche inférieure et de couche supérieure. Le mécanisme de fixation long (220a) de la couche supérieure (216a) recouvre le mécanisme de fixation court (220c) de la couche inférieure (216b) et vice versa. Un câble d'accrochage ou d'installation (222) est disposé entre chaque ensemble respectif de connecteurs pour former une couture. La paire de connecteurs pour chaque ensemble de boucles de couture a différentes longueurs dans la direction MD de sorte que les câbles d'accrochage ou d'installation de couches adjacentes se trouvent décalés dans la direction MD.
