  • the sheet with the tesserae is positioned inside the mould, so that the surface of the laminated sheet without tesserae is in contact with the bottom of the mould.

  • the mosaic pattern or its contour may be printed on the sheet.
  • the sheet thus obtained is positioned inside the mould. Obviously since the visible face of the slab will be that directed towards the bottom of the mould, the pattern must be prepared accordingly, namely mirrored.

Since there is the possibility of using inert materials which have a more uniform particle size distribution, slabs with superior aesthetic qualities and greater mechanical strength characteristics are obtained.

  • the mixture is vibrated under a vacuum, with obvious advantages in terms of elimination of the air from the mixture. It is possible to obtain a finished product with superior aesthetic and mechanical properties since it is does not have air bubbles which negatively affect the mechanical strength as well as the resistance to staining with absorption of liquids and dust inside the pores.
  • the product of the present invention in view of its characteristics described above, may be advantageously used both for flooring as well as for internal and external cladding and for furnishing.
  • the laminated sheet is positioned inside the mould after the tesserae of the mosaic have been applied beforehand on top of it, in the manner described above, namely with the use of a special adhesive, manually or also using robotic devices.

Abstract

La présente invention concerne un procédé de fabrication de dalles ayant une composition mosaïque comportant les étapes consistant à : placer sur un moule une feuille laminée sur laquelle une pluralité d'éléments mosaïques sont fixés ; verser dans le moule un mélange comprenant un granulé de matériau de pierre naturelle, et un mélange de liant composé d'un liant cimentaire, d'eau et d'un fluidiseur pour les mélanges de ciment, afin d'obtenir une couche d'épaisseur prédéfinie ; désaérer le mélange en appliquant un vide avec une première valeur durant un laps de temps prédéterminé, lesdites valeurs de vide et de temps étant conçues pour permettre une désaération essentiellement complète des cavités interstitielles et pour évacuer l'air restant qui peut être incorporé au mélange de départ ; appliquer un mouvement vibratoire dans une condition de vide ayant une seconde valeur inférieure à la première valeur de vide, durant un laps de temps prédéterminé. Ensuite, une première étape de prise et de durcissement du liant cimentaire formant la dalle est réalisée ; la dalle est retirée du moule, la feuille est retirée et la cuisson peut avoir lieu, avant l'étalonnage et le polissage de la dalle.
