Abstract

L'invention concerne un rouleau de presse à héliogravure. Ce rouleau comprend un corps ou manchon (15) moulé à partir de compositions synthétiques comprenant des microbilles de plastique, de verre ou de céramique, par exemple, dans une matrice de polyuréthane. Le manchon (15) est usiné à la taille requise et ensuite un revêtement de cuivre (17) est déposé sur la surface usinée, et traité au chrome. Un revêtement électriquement conducteur est d'abord déposé sur la surface usinée, lequel revêtement comprend un agent conducteur comme un métal finement divisé.
