Abstract

PROCESSO PARA A PRODUçãO DE PAPEL EM CAMADAS MúLTIPLAS E DISPOSIçãO PARA UMA REALIZAçãO. A presente invençãio fornece um papel que inclui pelo menos duas camadas na direção z, que por sua vez estão na direção y, dividido em pelo menos dois campos com propriedades que diferem entre si e que se estendem na direção x. Essas propriedades podem ser óticas ou tácteis, preferencialmente óticas. Tal papel é seguro contra falsificação por apresentar uma aparência quando observado de cima para baixo, e apresentando um outro padrão escondido que se torna evidente quando olhado através do papel. Uma disposição para a produção de tal papel inclui meio de disposição de matérias-primas em posições exátas na tela de laminação, ambas nas direções y e x do papel. A presente invenção inclui também um processo para a produção de tal papel.PROCESS FOR THE PRODUCTION OF PAPER IN MULTIPLE LAYERS AND A PROVISION FOR IMPLEMENTATION. The present invention provides a paper that includes at least two layers in the z direction, which in turn are in the y direction, divided into at least two fields with properties that differ from each other and that extend in the x direction. These properties can be optical or tactile, preferably optical. Such paper is safe from counterfeiting because it has an appearance when viewed from the top, and has another hidden pattern that becomes evident when looked through the paper. A provision for the production of such paper includes means of disposing raw materials in exact positions on the lamination screen, both in the y and x directions of the paper. The present invention also includes a process for producing such paper.
