Abstract

L'invention concerne un dispositif permettant la fabrication d'un papier de sécurité, une première partie humide (1) d'une machine à papier formant une première bande de papier et étant éventuellement pourvue de caractéristiques d'individualisation, telles qu'une ouverture, un élément de sécurité sans fin ou un filigrane, et une deuxième partie humide (2) d'une machine à papier formant une deuxième bande de papier. Un dispositif d'aspiration élimine de la première et/ou de la deuxième bande de papier, lorsqu'elles sont encore humides, et en au moins un emplacement, des fibres de papier, de préférence en repérage avec les caractéristiques d'individualisation éventuellement présentes de la première bande de papier. Ensuite, la deuxième bande de papier et la première bande de papier sont réunies par une bande amovible (8) et assemblées solidement. Selon l'invention, le dispositif d'aspiration comprend une bande transporteuse sans fin (9) composée d'un tissu du type toile ou d'une surface fermée, la bande transporteuse sans fin présentant au moins un évidement en repérage avec le ou les emplacements au niveau desquels les fibres de papier seront éliminées de la bande de papier encore humide. La bande transporteuse sans fin est tendue sur au moins deux rouleaux-guides (3) réglables en position. Un cylindre aspirant (4) ou une caisse aspirante (7) est disposé(e) sur la face de la bande transporteuse sans fin opposée à la bande de papier, le cylindre aspirant ou la caisse aspirante produisant une dépression et aspirant les fibres de papier à travers les évidements de la bande transporteuse.
