Definitions

  • the present invention relates to a method for cutting stone-like elements into layers.
  • the ceramics industry has long employed stone-like elements or even just stones of different kinds which, cut appropriately into layers of various thicknesses are inserted in products as a natural decorative complement in order to improve the already high aesthetic qualities of these products.
  • Cut stones in fact show, on their cutting planes, all the veins and colors of the elements that form them; accordingly, decorations formed with them assume particular effects which are currently highly sought by the market.
  • the stone-like elements are currently cut by resorting to an absolutely crude method, by using a blade or a plurality of blades assembled in a pack, to which each stone is individually offered for cutting, one stone at a time.
  • the technical aim of the present invention is to solve the above-cited problems of the prior art by providing a method for cutting stone-like elements into layers which allows to perform the cutting rapidly, can be applied industrially by using automatic machines, and has a substantially high cycle efficiency with respect to the one obtainable by applying current manual methods.
  • a method for cutting stone-like elements into layers characterized in that it comprises the steps of arranging stone-like elements in mutual contact in a substantially impermeable container; filling said container with a liquid until at least part of the height of the stone-like elements is covered; freezing said container, said stone-like elements and said liquid thus prepared, obtaining a monolith; and cutting said frozen monolith into layers.
  • the reference numeral 1 designates a tray-like container, optionally but not necessarily of the throwaway type and substantially impermeable, in which the stone-like elements 2 are arranged side by side so that they stabilize each other.
  • Water or a fast-freezing liquid is then poured into the container 1 in such an amount as to reach a level which covers, at least to a significant extent (preferably completely), the height of the stone-like elements 2; the container 1 is provided with at least one opening 1a for the overflow of the liquid in order to provide uniform vertical dimensions for each frozen monolith to be produced.
  • the container 1 thus prepared is then placed in a conventional freezer means and can be stacked and stored together with others on shelves, ready for use.
  • the monolith After complete freezing of the container and of the water, which accordingly includes in the monolith the stone-like elements 2 as well, the monolith is removed from the freezer in order to be subjected to the actual cutting step.
  • the container 1 is of the throwaway type, it is cut together with the monolith, whereas if the container is of the conventional type, for example made of plastic, it separates by leaving it outside the freezer means for a few minutes and is then recovered.
  • Cutting of the resulting monoliths, optionally placed on a conveyor 3 and performed even by conventional cutting machines 4, is extremely easy and precise and allows to slice into preferably but not exclusively vertical layers each monolith and therefore the stone-like elements 2, which once they return to ambient temperature can be separated and employed to form decorations.
  • the entire method has a substantially short execution and completion cycle and therefore the overall production efficiency is considerably higher than the conventional manual method.
