Beschreibung
Zusammenfassung:	The invention relates to a multilayered paper for the production of valuable documents which contains reinforcing strips in certain places along the length and/or width of the paper web and is characterized in that the reinforcing strips are produced by the formation of an additional fibrous layer on the surface of the paper, wherein the specific weight of the paper in the places where the additional fibrous layer is formed is greater than the specific weight of the main field of the paper. The additional fibrous layer on the surface of the paper can be formed as a result of additional grooves on the surface of the mesh of a mesh cylinder. The invention offers a simpler and more reliable solution to the problem of bent corners and mechanical damage to the edges of banknotes and other documents and also of reinforcing the entire structure of the paper. L'invention concerne un papier multicouche pour la fabrication de documents de valeur comportant des bandes de renfort dans des endroits prédéterminés sur la longueur et/ou la largeur de bande de papier, caractérisé en ce que les bandes de renfort sont obtenues en formant une couche fibreuse supplémentaire sur la surface du papier, le poids spécifique du papier aux endroits où est formé la couche fibreuse supplémentaire étant supérieur au poids spécifique du champ principal du papier. La couche fibreuse supplémentaire à la surface du papier peut être formée à l'aide de gorges supplémentaires à la surface de la grille d'un cylindre d'impression. L'invention offre une solution plus simple et plus fiable au problème d'écornage des coins et des dommages mécaniques sur les bords des billets de banque ou d'autres documents, et simplifie en outre toute la structure du papier.
