The invention relates to a laminated clothing for a papermaking or cellulose manufacturing machine, as well as a method and a blank for manufacturing thereof. The clothing comprises two laminated layers (O, I), each having an inclined direction-defined thread system, the thread systems being inclined relative to the machine direction of the clothing and relative to each other. The two layers (O, I) constitute an upper and an inner part, respectively, of an endless band (40), which is so flattened that two edge folds (48, 50) are formed transversely of the machine direction, and which is then doubled with the edge folds (48, 50) coupled together. As a result, the band comprises a direction-defined thread system which is inclined relative to the machine direction and which, owing to the flattening and doubling of the band, forms the thread systems, inclined relative to each other, of the first and the second layer (O, I).
La présente invention concerne un matériau de montage stratifié destiné à une machine à papier ou à cellulose. L'invention concerne également un procédé et un flanc permettant la fabrication dudit matériau. Le matériau de montage est constitué de deux couches superposées (O, I) caractérisées par des systèmes de droit-fil inclinés par rapport au sens machine du matériau et l'un par rapport à l'autre. Les deux couches (O, I) constituent respectivement la partie supérieure et la partie intérieure d'une bande sans fin (40) qui est aplatie de façon que les deux plis de lisière (48, 50) se forment transversalement au sens de la machine, la bande se dédoublant alors en raison du couplage des plis de lisière (48, 50). Il en résulte une bande présentant un système de fils à orientation définie, incliné et qui, en raison de l'aplatissement par rapport au sens machine et du dédoublement de la bande, forme les systèmes de droit-fil inclinés l'un par rapport à l'autre de la première et la seconde couche (O, I).
