Definitions

  • the present invention relates to a method for manufacturing antique mosaic tesserae and to a mosaic comprising tesserae as obtainable thereby.
  • tesserae are shaped by cutting a matrix which can be constituted by a slab of marble or by a glazed tile.
  • Cutting is performed by using a plurality of circular blades which are all keyed on a single motorized shaft rotationally driven by an adapted motor unit.
  • Said blades rotated and locked on the shaft with gaps which are preset according to the dimensions of the tesserae to be produced, cut the marble or the tile starting from the exposed surface until they cut through the entire thickness.
  • Another method for forming said tesserae consists in performing pre-scoring, on both faces of the matrix, with a sort of glass cutter provided with a wheel made of diamond or equivalent material, and in then fracturing said matrix along the pre-scoring lines, which in this case are perfectly straight too.
  • Another specific problem of mosaics composed of tesserae manufactured according to conventional technologies is the fact that after laying, due to the limited contact surface of the tesserae and to the consequently limited surface for gluing to the application surface, if said tesserae are stressed for example by intensive treading, some of them may detach from the laying surface, spoiling the figurative composition of the mosaic and even compromising its integrity due to the natural tendency of the effects of weather to creep through the openings left by the missing tesserae, attacking and degrading the foundation adhesive.
  • the technology used i.e., the cutting of the marble or of the tiles starting from the exposed surface, causes a significant waste of valuable material due to the loss produced by the thickness of the blades when they cut into it.
  • the principal aim of the present invention is to solve the above problems of the prior art by providing a method for manufacturing antique mosaic tesserae which makes them visually different from each other, as if manufactured by hand one by one, and at the same time makes them significantly more stable once they have been laid and also allows a significant saving in the material used to manufacture them.
  • the reference numeral 1 generally designates a cutting unit composed of a plurality of circular blades 2 keyed on a motorized shaft 3 which is rotationally driven by a corresponding motor 4.
  • the cutting unit 1 by moving downwards to a preset level, scores the back, and only the back, of said matrix 5, forming thereon lines 6 for preferential fracture caused by the reduced resisting cross-section of the thickness, at the same time saving the valuable material used for the exposed face.
  • the scoring is performed usually, but not exclusively, in the two perpendicular planar directions (i.e., along the directions that form the edges of the perimeters of the tesserae to be manufactured), so as to create on the back of the matrix 5 a sort of grid which has, in the example, a square mesh.
  • the matrix 5 is then passed, for example, through a fracturing machine of a conventional type, which separates the various tesserae 7 formed previously by the grid.
  • the resulting tesserae 7 are all placed in a so-called “tumbling barrel", so that said irregular and sharp edges become rounded and safe.
