A method for producing a material strip (1) comprising microstructures, particularly a laminated material strip having at least two layers and comprising security-relevant features (18), in that at least one material strip formed by two strips (1', 1") running parallel to each other in an aligned manner is guided through a machine containing at least heating (8, 9), pressing (12, 13) and cooling means (10, 11), wherein transport means (2, 3) for the material strip are equipped with elements (19) that have a profile comprising the respective microstructures, and said profile is reproduced on the material strip over the course of the heating and pressing operations.
La présente invention concerne un procédé de fabrication d'une bande de matériau (1) contenant des microstructures, notamment une bande de matériau stratifiée ayant un minimum de deux couches et contenant des caractéristiques (18) touchant à la sécurité. Au moins une bande de matériau, formée de deux bandes (1',1' ') parallèles alignées, est insérée dans une machine comportant au moins des moyens de chauffage (8, 9), de compression (12,13) et de refroidissement (10,11), des moyens de transport (2, 3) de la bande de matériau étant équipés d'éléments (19) présentant un profilé contenant les microstructures respectives et ce profilé étant formé sur la bande de matériau au cours du processus de chauffage et de compression.
