Abstract

La présente invention se rapporte notamment à un procédé de fabrication d'un matériau (6) constitué de fibres et conformé en bande, par voie papetière humide, ce matériau (6) étant multicouches et comportant une première couche (4) de fibres et au moins une deuxième couche (5) de fibres assemblées l'une à l'autre, procédé au cours duquel chaque couche de fibres (4, 5) est formée individuellement par égouttage sur une toile de formation (3) dans une section de formation (1), puis acheminée en bande vers une section d'assemblage (2) dans laquelle lesdites couches (4, 5) sont assemblées pour former le matériau multicouches (6), et ensuite vers une section de déshydratation et de séchage, caractérisé par le fait que l'on procède à l'enlèvement, à l'aide d'un fluide sous pression, entre lesdites sections de formation (1) et d'assemblage (2), d'au moins un ruban longitudinal (R) de matière fibreuse dans l'une (4) seulement desdites couches (4, 5) de manière à y former une fenêtre longitudinale continue.The present invention relates in particular to a method of manufacturing a material (6) consisting of fibers and shaped as a strip, by the wet papermaking process, this material (6) being multilayer and comprising a first layer (4) of fibers and at least a second layer (5) of fibers joined together, a process in which each layer of fibers (4, 5) is individually formed by draining onto a forming wire (3) in a forming section ( 1), then conveyed in a strip to an assembly section (2) in which said layers (4, 5) are assembled to form the multilayer material (6), and then to a dewatering and drying section, characterized by the causes the removal, with the aid of a pressurized fluid, between said forming (1) and assembly (2) sections of at least one longitudinal strip (R) of material fibrous in only one (4) of said layers (4, 5) so as to form a longitudinal window therein. dinale continues.
