Definitions

• the present invention relates to a method for manufacturing stratified panels made of stone-like material and glass, particularly for providing furniture components or light diffusers.
• stratified panels which are formed by a slate of stone-like material, typically marble, and by a glass plate, which is mated to the slate of stone-like material by means of a layer of bonding material.
• Such panels are used for making architectural or furniture components, such as dividing walls, doors, items of furniture or the like, or to make lampshades or light diffusers to be applied to lamps or other lighting devices, such as skylights or the like.
• stratified panels with a glass plate of thickness 2-3 mm especially if they have sides of large dimensions, often undergo damage or breakage owing to the vibrations transmitted to the slate of stone-like material and to the glass plate by the tools used to carry out the cuts to measure of the panel.
• Another problem that arises during the manufacture of this type of stratified panel is that of contouring the ends of the stratified panel with an angle of inclination, for example 45°, with respect to the flat faces of greatest extension, in order to make it possible to angularly join multiple stratified panels at their edges, in order to make, for example, architectural or furniture objects or components that are complex in form, such as, for example, shower stalls, tables, wash basins, lampshades or the like.
• tempered glass plates is not compatible with current procedures for working on stratified " panels made of stone-like material and glass.
• tempered glass plates owing to the considerable mechanical resistance characteristics conferred by the tempering process, are not suitable either for cutting to measure or for other types of processing, such as making through holes or finishing at the perimetric edges.
• the aim of the present invention is to solve the above-mentioned drawbacks, by providing a method for manufacturing stratified panels made of stone-like material and glass, particularly for providing architectural or furniture components or light diffusers, which makes it possible to produce this type of stratified panel using tempered glass plates.

• Figure 12 is a sectional schematic view of the slate of stone-like material according to the embodiment of Figure 11.
• a method for manufacturing stratified panels made of stone-like material and glass involves, initially, mating, on at least one face of a slate of stone-like material 1, at least one tempered glass plate 2, which has smaller dimensions than those of the slate of stone-like material 1 , so that the tempered glass plate 2 can be mated to the slate of stone-like material 1 over the entire extent of one of its faces.
• the tempered glass plate 2 has a predefined contour, which conveniently is executed on it, together with any provision of holes, beading or other work, before being subjected to the thermal tempering treatment.
• the tempered glass plate 2 is obtained from a normal sheet of glass which first is cut to measure, contoured and finished according to the end requirements of the stratified panel to be made, and then is sent to the tempering process.
• the ends of the tempered glass plate 2 are polished and cut at right angles or at an angle inclined to its faces of greatest extension, before the tempering treatment, so that the tempered glass plate 2 is already prepared in order to allow the angular joining of the finished stratified panel with other panels along their perimetric edges, as shown, for the purposes of example, in Figure 10.
• any through holes that are required in the tempered glass plate 2 must be made before tempering as well.
• the starting thickness of the slate of stone-like material 1 can be, for example, comprised substantially between 6 mm and 3 mm, while the glass plate 1 can have, conveniently, a thickness of about 2-5 mm or even higher.
• At least one sheet-like safety element 3 is positioned, which, in addition to giving a high mechanical resistance to the assembly, acts to keep fragments of glass or of stone-like material in position, in the event of breakage of the panel.
• the sheet-like safety element 3 can be, for example, constituted by a cloth fabric of glass fiber or by a sheet of plastic material with high mechanical resistance, such as, for example, ethyl vinyl acetate (EVA) or polyvinyl butyral (PVB).
• EVA ethyl vinyl acetate
• PVB polyvinyl butyral
• the mating between the slate of stone-like material 1 and the tempered glass plate 2 is carried out by means of interposing a layer of bonding material 4, which can be, for example, constituted by an epoxy resin or by the same sheet of EVA or PVB which is optionally used to make the sheet-like safety element 3.
• a layer of bonding material 4 can be, for example, constituted by an epoxy resin or by the same sheet of EVA or PVB which is optionally used to make the sheet-like safety element 3.
• a retaining element constituted, for example, by an adhesive tape 5
• an adhesive tape 5 can conveniently be applied around the slate of stonelike material 2 and the glass plate 3, so as to keep both locked in position during the mutual adhesion operation.
• the action of mutually compressing the tempered glass plate 2 against the slate of stone-like material 1 can, for example, be performed by using rollers for the purpose.
• evacuating the air present between the slate of stone-like material 2 and the tempered glass plate 1 can also be achieved by placing the slate of stone-like material 1 and the tempered glass plate 2, mutually mated, in an autoclave in which a vacuum is created before performing the heating and obtaining, as a consequence, the hardening of the layer of bonding material 4.
• this progressive removal of material is carried out along a direction that has at least one component which is substantially perpendicular to the perimetric edge of the slate of stone-like material 1 and proceeds until the perimetric edge of the slate of stone-like material 1 is substantially flush with the edge of the glass plate.
• the removal of the portion la of the slate of stone-like material 1 comprises, advantageously, the execution of a lateral milling of the slate of stone-like material 1.
• this lateral milling is earned out, in general, using at least one tangential mill 8, which is turned about an axis 8a that is substantially perpendicular to the plane of arrangement of the slate of stone-like material 1 and which has, for example, on its lateral working surface, a plurality of diamond teeth, which are not shown for the sake of simplicity.
• the tangential mill 8 is brought to engage, with its lateral working surface, against the perimetric edge of the slate of stone-like material 1. During the processing, the tangential mill 8 is, therefore, moved, with respect to the slate of stone-like material 1 , along a direction that has at least one component which is substantially perpendicular to the perimetric edge of the slate of stone-like material 1, so as to progressively remove the portion la of the slate of stone-like material 1.

• abutment and positioning element 13 On the resting surface 12 there is at least one abutment and positioning element 13, which is constituted, conveniently, by a block of material with a low friction coefficient with respect to tempered glass, such as for example the material known by the commercial name TEFLON.
• the abutment and positioning element 13 is, advantageously, movable on the resting surface 12 as a function of the dimensions of the semifinished panel 7 and is designed to engage an edge of the tempered glass plate 2 of the semifinished panel 7.

• this gauging step is performed in multiple passes by means of the use of a frontal mill 15 which is turned about an axis that is substantially perpendicular to the plane of arrangement of the slate of stonelike material, as shown schematically in Figures 7 and 8.
• the slate of stonelike material 1 can be, conveniently, subjected to other forms of finishing, such as polishing, buffing, brushing, sandblasting and so on, according to the aesthetic characteristics required.
• finishing of the ends of the slate of stone-like material 1 can be executed so as to buff them and/or cut them in such a way as to match the ends of the tempered glass plate 2, so as to give the stratified panel thus obtained the function and appearance of a single panel.
• a finished stratified panel that has a first layer, made from the slate of stone-like material 1, and a second layer, which provides robustness to the panel and which is made from the tempered glass plate 2, so as to give the panel considerable mechanical resistance characteristics.
