Definitions

  • This invention relates to an apparatus and a method for obtaining a product, in particular a product intended for the installation of finishes of building products in general; also a new product being included within the scope of the present invention.
  • the through openings can be obtained by removing from the already formed support a certain quantity of material that makes it up initially.
  • This removing operation can be achieved by computer controlled water-jet cutting machines advancing continuously to perform the cutting operation along the corresponding perimeter of the opening that is to be defined.
  • Such machines have to be programmed afresh to change over from the creation of openings having a preset shape to the creation of openings having different shapes.
  • a not insignificant time is also required for programming the cutting machines whenever one wishes to change the shape of the openings to be obtained on the ceramic products.
  • a further drawback is that the cutting machines are programmed to obtain openings of different shapes without taking into account any variations in the thickness of the ceramic products, due for example to the presence of bas-relief on the surface thereof.
  • the openings are obtained directly during the phase of forming the support.
  • moulds are used that are provided with cores fixed to the base of the mould cooperating with punches that have holes corresponding to the section of the cores and are shaped according to the particular shape of the openings to be made.
  • One drawback of the system disclosed above is that it requires dedicated moulds that must be built on demand and that must to be replaced whenever one wishes to modify the number and/or the shape and/or the position of the openings provided on a given product.
  • One object of the invention is to simplify the methods and the apparatuses for obtaining products.
  • a further object is to supply an apparatus and a method for obtaining products that may be used independently of the particular configuration of the products that one wishes to obtain.
  • Yet another object is to supply products that are provided with openings made with great precision whilst keeping cost very moderate.
  • a method comprising forming a product, providing cavity means extending to the inside of said product and defining on an intended visible surface a contour of an opening, characterized in that it further comprises subsequently providing further cavity means extending from a surface opposite said intended visible surface for such a depth that a bottom part of said cavity means is removed.
  • said cavity means is shaped like an indentation that delimits the perimeter of a rusticated element having any desired shape.
  • an apparatus comprising removing means arranged for making an opening in a product provided with cavity means extending from an intended visible surface of said product, characterized in that said removing means is configured in such a way as to remove a part of said product from a surface opposite said intended visible surface until a bottom portion of said cavity means is removed.
  • said removing means enables a portion of said product to be removed having a length approximately corresponding to the length of said product.
  • said removing means enables a portion of said product to be removed having a width less than or also approximately corresponding to the width of said product.
  • a product comprising cavity means extending to the inside of body means of said product starting from its own intended visible surfaces and defining on said intended visible surface a contour of an opening, characterized in that it further comprises further cavity means having a greater extent than said cavity means and extending from a surface opposite said intended visible surface for such a depth that said cavity means is lacking in its own bottom portion.
  • said cavity means is delimited by edge means having at least one portion that is tilted in relation to said intended visible surface.
  • the further cavity means can have a preset shape, for example rectangular or square, completely independently of the shape of the openings, particularly when the latter have tilted edges.
  • the further cavity means may have an extent equal to a longitudinal and/or transversal dimension of said products.
  • a composite element comprising product means provided with a plurality of opening means and decorating means associated with said product means and comprising a plurality of protruding means shaped in such a way as to be shapingly coupled with said opening means.
  • this decorating element has significantly larger dimensions than the single tesseras
  • handling operations are further simplified, furthermore, as the dimensions of the decorating element do not depend on the dimensions of the openings of the product means, it is possible to create openings with dimensions that are even very small without being consequently forced to use tesseras of the corresponding dimensions.

  • the tiles 31 have a thickness S1 that is the same as the thickness S2 of the decorating element 14.
  • the decorating element 14 can be obtained by cutting a tile 31 so as to obtain a tessera having dimensions that are such as to be able to be received inside the through channel 26.
  • the presence of the net 18 enables transport and installation of the composite product 20 to be facilitated and furthermore enables the stability thereof to be increased, preventing, for example, mutual shifts between the listel 1 and the decorating element 14.
  • a further decorating element 140 having a thickness that is less than the distance between the bottom surface 8 and the resting portions 3 can be associated with the ceramic listel 1.
  • Adhesive materials are used in this case in order to ensure stable cohesion between the further decorating element 140 and the ceramic listel 1.

  • Figure 12 furthermore shows that the listel 1 has a substantially constant thickness even in shaped zones 28 obtained at opposite ends thereof.
  • the uniform thickness enables, in cases in which the listels are obtained by pressing, substantially constant density to be obtained at all points of the ceramic listels. This enables dimensional lack of uniformity between listels of the same type to be avoided.
  • listel 1 provided on its not visible surface 6 with a pair of hollows 29 having the same function as the above-disclosed grooves 11.
  • the hollows 29 are not made by tools but are obtained during forming of the listel 1.
  • listel 1 provided on its not visible surface 6 with a pair of throats 30 performing the same function as the grooves 11 and the hollows 29 disclosed above.
  • the throats 30 are obtained during forming of the listel 1.
  • the grooves 11, the hollows 29 and the throats 30 have a greater depth S than the further distance D2 identified between the bottom surface 8 and the not visible surface 6.
  • Figures 18 to 22 show subsequent phases of a production cycle of a composite product according to the invention made by associating a listel 1 with a decorating element 14.
  • FIG 18 there is shown a listel 1 obtained by forming, for example by pressing ceramic powders.
  • Figure 19 there is shown with cross-hatching a volume of material that has to be removed from the ceramic listel 1.
  • Figure 20 shows grooves 11 made by a disc tool in the not visible surface 6 of the listel 1.
  • the grooves 11 enables the sides 19 of abrading means arranged for removing the afore said volume not to interfere with the material that forms the listel 1.
  • Figure 21 shows the listel 1 after the volume of material has been removed.
  • Figure 22 shows the decorating element 14 fixed to the listel 1 by appropriate amounts 141 of adhesive material that are interposed between the listel 1 and the decorating element 14.
  • the phase of the processing cycle during which the grooves 11 are made can be eliminated if, as shown in Figures 12 and 13 disclosed above, the listel 1 is provided with hollows 29, or throats 30 made during forming.
