摘要

Method for obtaining sheets, cartons or other bodies of fibrous material, pressing this material in wet to a reduced weight per unit volume, providing at least one face of the material of alternate recesses and protrusions by pressing with mold, and pressing or squeezing with greater hardness or compactness the bottoms of the recesses than the material of the shoulders; characterized in that the body is produced by combining at least two essentially similar sections, which are pressed separately and assembled so that the projections of one face of one of the sections fit into the recesses of the opposite face of the other fibrous element, and both sections combine to form a composite body, suitably employing an adhesive applied to the bonding surfaces.
