Definitions
- the invention relates to a method of decorating a flat element, in particular a floor element, and a flat decorated element.
- a raised floor sometimes also called a floating floor, consists of: column supports, of adjustable length, which rest on the surface to be paved; a weight-bearing structure, for example a reticulated structure, consisting of beams arranged according to a flat net having generally square meshes, supported at the nodes of the meshes by the column supports; panels, generally square and of a size substantially analogous to the size of the meshes, resting on or fixed to the beams of the weight-bearing structure at the perimeter edges of each panel; a top cladding that covers each panel and performs several functions, including that of giving the desired appearance to the floor.
- top cladding such as PVC, linoleum, rubber, carpet, laminate, wood, ceramics, marble, granite or cement or resin agglomerate.
- the panels comprise a bottom lamina which is rested on the weight-bearing structure, a central body arranged on the bottom lamina and possibly a further metallic lamina that acts as a base plane for the top cladding.
- One disadvantage of the prior-art panels is that, in order to obtain a desired appearance, onto each panel a cladding element must be glued made of a material having the desired appearance.
- the process of manufacturing the clad panel is therefore complex and expensive.
- the manufacturer in order to be able to manufacture clad panels of various types, the manufacturer must use cladding elements of various materials and fix them to the base panel by means of adhesives and with applying methods that depend on the material of the cladding element.
- a manufacturer of clad panels must therefore have a warehouse supplied with many adhesives that are different from one another and use machines and equipment that are specially dedicated to preparing and applying each adhesive.
- Another disadvantage is that in order to obtain clad panels having a standardised thickness, it is necessary to use, in combination with each type of cladding element, a special type of panel conformation.
- the thickness of the panel or the presence and type of lamina that covers the central body varies according to the chosen top cladding element. For example, the central body has low thickness when it has to be clad with a marble slab and has high thickness when it has to be covered with a rubber cladding element.
- the cladding element causes a significant increase in the weight of the panel, particularly when said element is made from a material with a high specific weight such as marble or agglomerates. This complicates the operations of transport and maintenance of the panel.
- a further disadvantage is that certain types of cladding elements such as linoleum, PVC, carpets and wood are flammable and when they burn they produce an enormous quantity of smoke; therefore, in the event of a fire, said cladding elements, by burning, cause the escape routes to be obscured and people to be possibly asphyxiated or intoxicated.
- An object of the invention is to improve the methods of decorating panels, in particular floor elements.
- a further object is to provide a method of decorating flat elements that enables a wide range of decorations to be obtained.
- a still further object is to simplify and make more versatile the production systems of flat elements, particularly those intended to be used in raised floors.
- a further object of the invention is to provide a flat element, in particular for floors, having a non-corrodible surface that is easily cleanable and washable with common detergents, having good resistance against fire and which does not require maintenance.
- the decoration comprises a decal.
- the decoration comprises a sublimable decoration.
- the decoration transferred onto the flat element has a much lower thickness than the thickness of the top cladding elements envisaged by the state of the art, the weight of the flat element is reduced in relation to a flat element provided with a known cladding element and the operations of transporting the flat element are simplified and less costly. Furthermore, in the event of a fire, the decoration produces a quantity of fumes or toxic substances that is much less than that occurring during the combustion of a carpet or of a linoleum cladding element.

Abstract
In a method of decorating a flat element, said decorating comprises transferring a decoration from a support member to a laminar member of said flat element.
A flat element comprises a laminar member on which a decorative arrangement is arranged, said decorative arrangement being free of cladding elements glued to said laminar member.
Description
- The invention relates to a method of decorating a flat element, in particular a floor element, and a flat decorated element.
- It is known to use floor elements, for example panels, to create raised floors. A raised floor, sometimes also called a floating floor, consists of: column supports, of adjustable length, which rest on the surface to be paved; a weight-bearing structure, for example a reticulated structure, consisting of beams arranged according to a flat net having generally square meshes, supported at the nodes of the meshes by the column supports; panels, generally square and of a size substantially analogous to the size of the meshes, resting on or fixed to the beams of the weight-bearing structure at the perimeter edges of each panel; a top cladding that covers each panel and performs several functions, including that of giving the desired appearance to the floor.
- There are different types of top cladding such as PVC, linoleum, rubber, carpet, laminate, wood, ceramics, marble, granite or cement or resin agglomerate.
- The panels comprise a bottom lamina which is rested on the weight-bearing structure, a central body arranged on the bottom lamina and possibly a further metallic lamina that acts as a base plane for the top cladding.
- One disadvantage of the prior-art panels is that, in order to obtain a desired appearance, onto each panel a cladding element must be glued made of a material having the desired appearance. The process of manufacturing the clad panel is therefore complex and expensive. In fact, in order to be able to manufacture clad panels of various types, the manufacturer must use cladding elements of various materials and fix them to the base panel by means of adhesives and with applying methods that depend on the material of the cladding element. A manufacturer of clad panels must therefore have a warehouse supplied with many adhesives that are different from one another and use machines and equipment that are specially dedicated to preparing and applying each adhesive.
- Another disadvantage is that in order to obtain clad panels having a standardised thickness, it is necessary to use, in combination with each type of cladding element, a special type of panel conformation. In fact, the thickness of the panel or the presence and type of lamina that covers the central body varies according to the chosen top cladding element. For example, the central body has low thickness when it has to be clad with a marble slab and has high thickness when it has to be covered with a rubber cladding element.
- Furthermore, the cladding element causes a significant increase in the weight of the panel, particularly when said element is made from a material with a high specific weight such as marble or agglomerates. This complicates the operations of transport and maintenance of the panel.
- A further disadvantage is that certain types of cladding elements such as linoleum, PVC, carpets and wood are flammable and when they burn they produce an enormous quantity of smoke; therefore, in the event of a fire, said cladding elements, by burning, cause the escape routes to be obscured and people to be possibly asphyxiated or intoxicated.
- An object of the invention is to improve the methods of decorating panels, in particular floor elements.
- A further object is to provide a method of decorating flat elements that enables a wide range of decorations to be obtained.
- A still further object is to simplify and make more versatile the production systems of flat elements, particularly those intended to be used in raised floors.
- A further object of the invention is to provide a flat element, in particular for floors, having a non-corrodible surface that is easily cleanable and washable with common detergents, having good resistance against fire and which does not require maintenance.
- According to a first aspect of the invention, there is provided method of decorating a flat element, wherein said decorating comprises transferring a decoration from a support member to a laminar member of said flat element.
- In one embodiment, the decoration comprises a decal.
- In a further embodiment, the decoration comprises a sublimable decoration.
- Owing to this aspect of the invention, it is possible to obtain on a flat element a wide range of decorations having high print definition. Since the decoration can be printed on the support member with print techniques that ensure high definition, such as rotogravure or silkscreen printing, it is possible to transfer onto the flat element a pattern no matter how complex and multicoloured.
- Furthermore, the process of manufacturing flat elements, particularly floor elements, for example for use in raised floors, is considerably simplified inasmuch as it is no longer necessary to use a top cladding element of a material having the desired appearance. In fact, if for example it is desired to obtain a flat element having the appearance of wood rather than marble, it is sufficient to modify the decoration and there is no need to change the material of the top cladding element as envisaged by the state of the art. This eliminates the need to use adhesives and application techniques that are specific to each type of chosen cladding element, and enables the same structure of the floor element to be used to produce floors with any desired appearance.
- Since the decoration transferred onto the flat element has a much lower thickness than the thickness of the top cladding elements envisaged by the state of the art, the weight of the flat element is reduced in relation to a flat element provided with a known cladding element and the operations of transporting the flat element are simplified and less costly. Furthermore, in the event of a fire, the decoration produces a quantity of fumes or toxic substances that is much less than that occurring during the combustion of a carpet or of a linoleum cladding element.
- According to a second aspect of the invention, there is provided a flat element comprising a laminar member on which a decorative arrangement is arranged, wherein said decorative arrangement is free of cladding elements glued to said laminar member.
- Owing to this aspect of the invention, it is possible to obtain flat elements decorated in various ways according to the desired finish that are easily handled and transportable. The invention can be better understood and carried out with reference to the enclosed drawings, which show an exemplifying and not restrictive embodiment thereof, in which:
- FIG. 1 is a perspective view of a raised floor according to the prior art;
- FIG. 2 is an enlarged and interrupted cross-section of a flat floor element according to the prior art;
- FIG. 3 is a perspective view of a flat element, for example a floor element;
- FIG. 4 is a front view of the flat element of FIG. 3;
- FIG. 5 is an enlarged cross section taken along the plane V-V of FIG. 4;
- FIG. 6 is a schematic view of a decorating apparatus for manufacturing the flat element of FIG. 2.
- With reference to FIGS. 1 and 2, a raised
floor 101 is shown comprisingcolumn supports 102, which rest on theground 103 to be paved, and a weight-bearingstructure 104, composed ofsection bars 105 so arranged as to form a flat net with square meshes. The weight-bearingstructure 104 is supported at the nodes of the mesh by the column supports 102. The raisedfloor 101 further comprisessquare panels 106 arranged in rows adjacent to one another, resting along their perimeter edge on the meshes of the weight-bearingstructure 104. Eachpanel 106 comprises atop cladding 107 which defines the appearance of the floor. In the configuration in FIG. 1, somepanels 106, which are moved by asuction cup 108, still have to be positioned to complete the floor. - As shown in FIG. 2, each known
panel 106 consists of abottom lamina 109 intended to rest on the weight-bearingstructure 104, acentral body 110 arranged on thelamina 109 and ametallic lamina 111, for example a galvanised sheet metal, that acts as a base plane for thetop cladding 107. Thetop cladding 107 may be of various types of material such as PVC, linoleum, rubber, carpet, laminate, wood, ceramics, marble, granite or cement or resin agglomerate and is fixed to themetallic lamina 111 by means of suitable adhesives or by exploiting the cohesive properties of the cladding (for example in the case of cement or resin agglomerate). - FIG. 3 shows a flat element according to the invention, for example a
floor element 1, intended to be installed on a weight-bearing structure of a raised floor, for example of the type shown in FIG. 1. The decorative pattern on thefloor element 1 may be complex and multicoloured as desired and may reproduce the veining of wood or the appearance of marble or granite or natural rock. - As shown in FIG. 5, the
floor element 1 comprises acentral body 3, possibly abase lamina 2 and atop lamina 4. Thebase lamina 2 may be a sheet of aluminium or laminated plastic or galvanised metal or stainless steel. Thecentral body 3 may be an agglomerate of cellulose fibres of wood, or of calcium sulphate or of calcium silicate. Thetop lamina 4 may be made of metallic material, and may comprise for example a sheet of galvanised or stainless steel. - In one embodiment, the
base lamina 2 may be shaped like a tray, provided withside walls 5 suitable for containing thecentral body 3. Theside walls 5 are obtained by bending by about 90° the edge zones of the sheet metal that forms the base lamina. Thetop lamina 4 may be shaped as a cover or it may haveside edges 6 obtained by bending by an angle of about 90° the strips obtained on the sides of the sheet metal that forms thetop lamina 4. The cover has a perimeter that is slightly greater than the perimeter of the tray and is arranged on thecentral body 3 in such a way that theside edges 6 extend from thetop lamina 4 to thecentral body 3. In the same way, theside walls 5 of the tray extend from thebase lamina 2 towards thecentral body 3. The tray and cover are reciprocally arranged in such a way as to give thefloor element 1 the appearance of a box closed by a cover. The tray and cover are both firmly anchored on thecentral body 3, for example by gluing. - An alternative structure, which is not shown, of the
floor element 1 comprises thecentral body 3, thetop lamina 4, possibly thebase lamina 2, and side walls covered by strips, each strip having a length equal to the length of the respective edge of the floor element and a height that is about the same as the thickness of the floor element. The strips are fixed or glued to the side walls. The strips may be of plastic material of various colours. - On the
top lamina 4 there is adecoration 8, for example comprising a plurality of layers. Thedecoration 8 may comprise a base layer 9 in contact with thetop lamina 4. The base layer 9 defines the base colour of the desired final decoration. The base layer 9 further improves adhesion of the subsequent layers to thetop lamina 4. - The manufacturer of decorated
floor elements 1 may apply the base layer 9 on thetop lamina 4, or may purchasefloor elements 1 provided withtop laminas 4 on which the respective base layer 9 has already been applied. In this latter case, thetop lamina 4 is for example obtained from a sheet metal in the form of a strip continuously prepainted by means of a suitable system. - The base layer9 may be absent if the colouring of the
top lamina 4 already corresponds to the desired base colour. - The base layer9 may comprise a thermosetting base paint, which uniformly covers the whole
top lamina 4 and which becomes anchored to thetop lamina 4 after setting. The base paint can be applied onto thetop lamina 4 in liquid form by means of a spray or roller device. Subsequently, the base paint freely polymerises in air, possibly with the help of a catalyst, or in a suitable heating apparatus within which theelement 1 is subjected to a time-temperature cycle that causes complete firing of the base layer 9. The base paint may also be applied onto thetop lamina 4 in powder form by means of known methods, for example of electrostatic or spray type. In this case, the powder softens and polymerises in a suitable heating apparatus. The powder may also be exposed firstly to infrared rays which soften it and then to ultraviolet rays which polymerise it. - On the base layer9 a
decorative layer 10 is then applied by means of a transfer technique. - The
decorative layer 10 may be applied by means of thedecorating apparatus 12 shown in FIG. 6. Thedecorating apparatus 12 comprises an unwindingroller 13 that unwinds from a reel 14 atransfer support 15. Thetransfer support 15 may comprise a film, for example made of polypropylene, on which thedecorative pattern 16 to be transferred onto the surface of thefloor element 1 has been printed. Thedecorating apparatus 12 further comprises a windingroller 17 that winds onto afurther reel 18 theexhausted transfer support 15, i.e. the transfer support free of thedecorative pattern 16 which has already been transferred onto thefloor element 1. Apressing drum 19 is provided for pressing thetransfer support 15 against the surface to be decorated. A supporting device, comprising for example a supportingroller 20, supports thefloor element 1 when thepressing drum 19 presses thetransfer support 15 against thefloor element 1. - The
decorative pattern 16 may comprise a decal previously printed on thetransfer support 15 by means of known printing techniques, such as gravure or silkscreen printing, the decal being suitable for being transferred onto thefloor element 1 by means of heat and pressure. The decal is transferred onto thefloor element 1 by applying temperatures comprised between about 50° C. and about 150° C. - In one alternative embodiment, the
decorative pattern 16 may comprise a sublimable decoration that is transferred onto thefloor element 1 by means of sublimation when heat and pressure are applied. The temperature at which the sublimable decoration is transferred onto thefloor element 1 is between about 130° C. and about 220° C. - Decals are particularly suitable for
floor elements 1 made of materials that cannot be exposed to high temperature, as may happen to certain adhesives or glues used between thecentral body 3 and thetop lamina 4 or thebase lamina 2. - The unwinding
roller 13, the windingroller 17 and thepressing drum 19 have respective rotation axes which are substantially parallel to one another and rotate in the same direction. - When the
rollers drum 19 rotate, thetransfer support 15 unwinds from thereel 14 and rewinds around thefurther reel 18. Thetransfer support 15 is maintained in a substantially taut configuration by thedrum 19 arranged in a roughly intermediate position along the path of thetransfer support 15. - The
pressing drum 19 exerts a pressure on the surface of thefloor element 1 as shown by the arrow P, thereby allowing thedecorative pattern 16 to be transferred from thetransfer support 15 to the surface of thefloor element 1, to form thedecorative layer 10. To enable detachment of the decal or of the sublimable decoration from thetransfer support 15, thepressing drum 19 is heated. Also the supportingroller 20 can be heated. Thefloor element 1 is conveyed along an advance direction A towards the pressingdrum 19 by a conveying device arranged below thepressing drum 19. The conveying device may comprise aroller conveyor 23. - After transferring the
decorative pattern 16 onto thefloor element 1, a transparent and highly viscousliquid varnish 21 may be applied onto thedecorative layer 10 by means of acurtain coating device 22. Thevarnish 21 forms aprotective layer 11 for thedecoration 8. - The
protective layer 11, shown in FIG. 5, can also be applied by means of roller or spray devices. Theliquid varnish 21 may be capable of polymerising when subjected to ultraviolet radiation that activates photoinitiators possibly included in theliquid varnish 21. Polymerisation of theprotective layer 11 is a rapid reaction that occurs by inserting thefloor element 1 into a UV kiln. - It is noted that the
protective layer 11 can also be applied in powder form. - To improve transfer of the
decorative pattern 16 from thetransfer support 15 onto thefloor element 1 it is possible to preheat thefloor element 1 before it enters theapparatus 12. Thefloor element 1 may be preheated at temperatures of between approximately 30° C. and approximately 100° C. with an infrared lamp, or in a suitable kiln.
