Definitions

  • the present industrial invention patent relates to a special configuration of the reverse face of ceramic paving or facing tiles.
  • Normal ceramic tiles are known to be constituted by a clay support which after forming is fired and glazed by one of the known ceramic double or single firing processes.
  • the reverse face or rear of these tiles is also known to comprise a series of feet or studs which have the double purpose of acting as spacers during the firing of the material when in a stacked condition, and of facilitating their grip against the respective surfaces on which they are laid.
  • a first drawback derives from the fact that the clay is more compacted at said studs than in the adjacent zones of the corresponding support, so that the differently compacted zones react differently to the application of the glaze and/or any decoration, so that different colour tones appear after firing said glaze and/or decoration.
  • tiles which have just been formed are particularly sensitive to impact acting in the plane orthogonal to that in which they lie, for example during their transfer along conveying lines, and they are thus easily subject to breakage.
  • the present invention provides and protects a special tile rear configuration able to obviate the aforesaid. This is attained according to the invention by providing a tile rear having a plurality of uniformly distributed hexagonal cells which cover the reverse face of the tile with the exception of a narrow perimetral rim, and which have a depth of between 0.5 and 3 mm.
  • said tile rear is configured as a honeycomb, so as to provide a perfectly plane rear resting face. Furthermore, according to the invention, a tile with this rear has very regular cross-sections, so that a tile which has just been formed is uniformly compacted and thus more resistant to impact, and during its firing there is almost regular shrinkage without appreciable variation in the planarity of the support or in the linearity of its sides, and its front face reacts uniformly to the application of glaze and/or decoration.
  • the tile rear according to the invention provides a coefficient of grip which has not been obtainable up to the present time.
  • Said figures show a ceramic tile 1 of right square or rectangular shape, but which can assume any other known tile shape.
  • the plane rear of this latter with the exception of a narrow perimetral band 2 which is internally coplanar with said rear whereas externally it extends into a bevel, is provided with a plurality of uniformly distributed hexagonal impressions 3.
  • the depth of these impressions 3 is of the order of 0.5-3 mm, and the average thickness of the separation ribs is between 1 and 2.5 mm.
  • the side of the hexagon can vary from 3 to 5 mm, and is preferably 4 mm.
  • the density of these impressions 3 is therefore between 4 and 1.5 impressions per square centimetre.
