Abstract

L'invention concerne un procédé de paquets monolithiques protégés contre les contrefaçons de feuilles de polycarbonate afin de produire différents papiers valeur, ceci en appliquant sur ces derniers des images perforées afin de rendre plus complexe les possibilités de contrefaçon d'un produit donné et réduire la quantité de paquets monolithiques rejetés de feuilles de polycarbonate. Le procédé consiste à former un paquet de feuilles distinctes de polycarbonate d'une épaisseur de 50-100 microns, à les relier afin de former un paquet monolithique et à perforer une section donnée du paquet monolithique à l'aide d'un rayonnement laser. Le paquet est disposé entre deux plaques parallèles rigides, et le paquet ainsi formé est chauffé graduellement depuis la température ambiante jusqu'à la température de ramollissement du polycarbonate; il est maintenu à chaque étape à des valeurs prédéterminées de température et de pression pendant 10-15 secondes afin d'égaliser et de stabiliser le gradient de température sur tout le plan du champ du paquet et, simultanément, lors de chaque étape suivante, on augmente la valeur de pression sur le paquet assemblé. On maintient le paquet lors de la dernière étape à l'état compressé jusqu'à la formation d'un paquet monolithique de 500-1000 microns d'épaisseur, on refroidit le paquet monolithique ainsi formé en même temps que les plaques jusqu'à la température ambiante, on dégage le paquet des plaques et on le dépose verticalement entre deux cadres parallèles; la perforation d'une section donnée du paquet monolithique de feuilles distinctes de polycarbonate se fait par rayonnement laser dans un champ de travail défini par les cadres.
