Definitions

  • the present invention relates to a procedure and equipment for the manufacture of slabs of ceramic and/or stone material.
  • the manufacture of slabs of ceramic and/or stone material generally involves a deposition phase of a basic material on a supporting surface, such as a belt or a mould, to form a slab to be compacted, and a subsequent pressing phase, in order to obtain a compacted slab.
  • the basic material may be made of a ceramic material or a mixture of minerals in granular form (e.g. marble, granite, glass, fragments of mirrors, and/or others) as well as quartz powder and, precisely, resins that act as binders.
  • phase is then carried out, such as e.g. firing and subsequent cooling, in order to obtain a product having high mechanical and chemical properties.
  • the equipment required to carry out these phases therefore includes the presence of a supporting surface, means for depositing the basic material on the supporting surface so as to form a slab to be compacted and pressing means to obtain a compacted slab.
  • a well-known type of equipment used to obtain this effect involves the use of a hopper that extends over the entire width of the slab to be obtained and inside which the basic material to be deposited on the supporting surface is loaded, since a relative movement is provided between the latter surface and the hopper itself.
  • the slabs obtained in this way have“longitudinal” veins, i.e. they do not cross the entire thickness thereof.
  • This drawback therefore prevents the creation of a so-called “through vein”, typical of natural stones, and is particularly evident in the case of slabs being manufactured with two surfaces that are orthogonal to each other, such as in the case of kitchen tops, bathroom tops or other similar applications, so that it is not possible to obtain a substantially continuous vein along the two orthogonal surfaces.
  • the layers of material are not deposited evenly on the supporting surface, so that the intensity of the color of the veins obtained is faded.
  • the main aim of the present invention is to devise a procedure and equipment for the manufacture of slabs made of ceramic and/or stone material that allows obtaining a wide variety of aesthetic effects in a simple and reliable manner.
  • one of the objects of the present invention is to create aesthetic variations characterized by colors and/or patterns not achievable using the natural materials mentioned above, thus allowing a particularly versatile and customizable production.
  • Another object of the present invention is to allow the predictability and reproducibility of the aesthetic effects obtained.
  • Another object of the present invention is to devise a procedure and equipment for the manufacture of slabs made of ceramic and/or stone material that allows overcoming the aforementioned drawbacks of the prior art in a simple, rational, easy, effective to use and low-cost solution.

  • pressing means 7 of the slab to be compacted L are arranged along the direction of forward movement 4.
  • the pressing means 7 are of a type known to the technician of this sector and generally involve the presence of a buffer, adapted to exert a force of predefined intensity on the slab to be compacted, and a counteracting element.
  • the pressing means 7 can vary constructively according to the type of material used and can be of a dynamic type (in particular in the case where the material used is of the ceramic type), i.e. they can comprise a pair of belts adapted to contact the opposite faces of the slab to be compacted L during its forward movement, where one of these belts acts as a buffer and the other as a counteracting element, or they can be of a static type, i.e. the buffer exerts the pressing force on the slab to be compacted when this is stationary.
  • the material contained in the collecting chamber 6 may be of the ceramic type, in atomized form, granules or flakes, and/or stone form (such as marble, granite, minerals or other natural stones), in the form of powder and/or granules and/or flakes and mixed with a cement or resin binder.
  • the material contained in the collecting chamber 6 may consist of a single type of material, or of a plurality of primary materials of different type and/or having different colours.

  • various aesthetic effects such as, e.g., veins V that cross the entire thickness of the slab to be compacted L.
  • the slabs to be compacted L thus obtained can therefore be of the ceramic type, intended to be subjected to a firing procedure, or of the type of slabs of mineral grit (also called quartz slabs), intended to be subjected to a vibro-compression procedure under vacuum.
