  • each sheet When transporting sheets through the printing unit, each sheet is provided with an adhesive pattern. Thereafter, the sheet is passed through the confining module, wherein by means of the press roller, the pressure sheet resting on the counter-pressure cylinder is brought into contact with the sheet material. In this case, the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet. After further transporting the printing sheet, the metallic layer adheres only in the area provided with the adhesive pattern. The carrier film is thus removed from the metallic layer in the region of the adhesive pattern. The used in this way transfer film is wound up again. The print sheet is laid out in the coated state.

Abstract

L'amenée des feuilles dans un module de revêtement en vue du transfert de couches de formation d'image depuis une feuille de transfert jusqu'à un matériau à imprimer doit pouvoir être réalisée de manière plus large. Dans ce but, un dispositif de revêtement qui applique des couches, des informations ou des éléments utiles sur la feuille de transfert est associé selon l'invention au guide de feuilles. Les couches supplémentaires sont transmises en même temps que la couche utile de la feuille de transfert dans le module de revêtement sur le matériau à imprimer. La feuille de transfert est amenée de préférence sensiblement tangentiellement sur un cylindre de presse.
