A multi-tier fabric loading harness for installing a fabric onto a papermaking machine. The loading harness has a first portion (400) with a supporting rigid member (410) that attaches to an end of the fabric in the cross-machine direction and a plurality of apertures (420) spaced across its width. The first tier (430) is formed by a rope sequentially laced through the apertures to form self-aligning loops. A second rope is sequentially laced through the loops of the first tier to form self-aligning loops for a second tier (440). A pull ring (450) gathers the loops of the second tier and is used to pull the fabric onto the papermaking machine.

L'invention concerne un harnais permettant de charger un tissu multi-niveau destiné à installer un tissu sur une machine à papier. Le harnais présente une première partie (400) dotée d'un élément rigide de support (410) fixé à une extrémité du tissu dans le sens transversal de défilement et une pluralité d'ouverture (420) espacées sur sa largeur. Le premier niveau (430) est obtenu par un câble qui est enfilé séquentiellement à travers les ouvertures afin de former des boucles à autocentrage. Un second câble est enfilé séquentiellement à travers les boucles du premier niveau afin de former des boucles à auto centrage pour un second niveau (440). Une bague de traction (450) réunit les boucles du second niveau et sert à tirer le tissu sur la machine à papier.
