Titolo: PROCEDIMENTO PER LA REALIZZAZIONE DI PANNELLI PER LA COSTRUZIONE DI COMPONENTI DI ARREDO E SIMILI Title: PROCEDURE FOR THE REALIZATION OF PANELS FOR THE CONSTRUCTION OF FURNITURE COMPONENTS AND SIMILAR
D E S C R I Z I O N E DESCRIPTION
Il presente trovato ha come oggetto un procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili, nonché un pannello con opportune caratteristiche estetiche e meccaniche ed un elemento di arredo che comprenda almeno uno dei pannelli citati. The present invention relates to a process for manufacturing panels for the construction of furniture components and the like, as well as a panel with suitable aesthetic and mechanical characteristics and a furniture element that comprises at least one of the aforementioned panels.
L'utilizzo del legno massello per la produzione di pannelli strutturali, in particolare pannelli per l'arredamento, è sempre meno frequente e, comunque, relegata a prodotti molto costosi. The use of solid wood for the production of structural panels, in particular panels for furniture, is less and less frequent and, in any case, relegated to very expensive products.
Infatti si tratta di una materia prima estremamente costosa. In fact it is an extremely expensive raw material.
E' normale ricorrere a pannelli ottenuti dall'aggregazione di unità elementari di legno, reciprocamente aggregate per mezzo di resine e collanti. It is normal to use panels obtained from the aggregation of elementary wood units, mutually aggregated by means of resins and adhesives.
In questo gruppo di materiali costituiscono le soluzioni tecniche di maggiore rilievo il cosiddetto compensato, il cosiddetto truciolare e l'MDF (medium density fiberboard, pannello di fibra a media densità). The most important technical solutions in this group of materials are the so-called plywood, the so-called chipboard and the MDF (medium density fiberboard).
Il compensato è prodotto da strati sottili di legno: gli strati sono generalmente incollati in modo che la direzione delle fibre di ogni strato sia perpendicolare al livello precedente, per garantire resistenza e stabilità, specie in condizioni di particolare umidità. The plywood is produced from thin layers of wood: the layers are generally glued so that the direction of the fibers of each layer is perpendicular to the previous level, to ensure resistance and stability, especially in conditions of particular humidity.
Il truciolato, o truciolare, è il nome con cui sono indicati, comunemente, i pannelli in fibra di legno composti di trucioli risultanti dallo scarto delle normali lavorazioni del legno. I trucioli sono impastati con materiali leganti e quindi pressati per produrre i pannelli; i pannelli ottenuti possono essere di diversi tipi a seconda del tipo di truciolo. Chipboard, or chipboard, is the name commonly used to indicate wood fiber panels composed of chips resulting from the waste of normal woodworking. The shavings are mixed with binding materials and then pressed to produce the panels; the panels obtained can be of different types depending on the type of chip.
L’MDF è realizzato con fibre di legno pressate insieme a resina o colla ad alte temperature, producendo così un materiale molto resistente: per certi versi potrebbe essere considerato un sottoinsieme del truciolare, ma la grande diffusione e l'interesse per questo specifico materiale rendono opportuno identificarlo come una classe autonoma. MDF is made with wood fibers pressed together with resin or glue at high temperatures, thus producing a very resistant material: in some ways it could be considered a subset of chipboard, but the great diffusion and interest in this specific material make it it should be identified as an autonomous class.
L'MDF è un materiale che si presta alla realizzazione di pannelli con buone prestazioni meccaniche e la possibilità di sottoporlo a laminazione consente di conferire alla faccia del pannello rivestita anche un buon aspetto (caratteristica fondamentale nel settore dell'arredamento). MDF is a material that lends itself to the production of panels with good mechanical performance and the possibility of subjecting it to lamination allows to give the face of the coated panel also a good appearance (a fundamental characteristic in the furniture sector).
Purtroppo però, osservando il pannello in MDF laminato, si riscontra necessariamente la presenza di una cornice di bordatura che identifica la discontinuità tra l'aspetto della lamina di rivestimento e quello della cornice stessa. Unfortunately, however, observing the laminated MDF panel, one necessarily finds the presence of an edging frame that identifies the discontinuity between the appearance of the covering sheet and that of the frame itself.
Tali caratteristiche escludono la possibilità di utilizzare i pannelli in MDF laminati per la realizzazione di componenti di arredo di alto livello estetico e qualitativo. These characteristics exclude the possibility of using laminated MDF panels for the creation of high-quality aesthetic and quality furniture components.
Compito principale del presente trovato è quello di risolvere i problemi sopra esposti, proponendo un procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili che consenta di realizzare pannelli con aspetto simile ed anche confondibile con quello del legno massello. The main aim of the present invention is to solve the above problems by proposing a process for the production of panels for the construction of furniture components and the like which allows to produce panels with a similar appearance and also confusable with that of solid wood.
Nell'ambito di questo compito, uno scopo del trovato è quello di proporre un procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili semplice ed applicabile su tavole in materiali del tipo dell'MDF, del truciolare e simili. Within this aim, an object of the invention is to propose a method for manufacturing panels for the construction of furniture components and the like which is simple and applicable on boards made of materials such as MDF, chipboard and the like.
Un altro scopo del trovato è quello di proporre un pannello per la costruzione di componenti di arredo e simili che presenti caratteristiche estetiche simili a quelle del legno massello e costi inferiori rispetto al medesimo. Another object of the invention is to propose a panel for the construction of furniture components and the like which has aesthetic characteristics similar to those of solid wood and costs lower than the same.
Un altro scopo del trovato è quello di proporre un elemento di arredo avente caratteristiche estetiche sostanzialmente simili a quelle del legno massello, pur presentando costi inferiori. Ulteriore scopo del presente trovato è quello di realizzare un procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili di costi contenuti relativamente semplice realizzazione pratica e di sicura applicazione. Another object of the invention is to propose a piece of furniture having aesthetic characteristics substantially similar to those of solid wood, while having lower costs. A further object of the present invention is to provide a method for manufacturing panels for the construction of furniture components and the like of low cost, relatively simple to make in practice and safe to apply.
Questo compito e questi scopi vengono raggiunti da un procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili a partire da un elemento laminare avente uno spessore predefinito, elemento laminare costituito da materiale scelto tra truciolato di legno, composito a base di fibra di legno a media densità, composito a base di fibra di legno a bassa densità e composito a base di fibra di legno ad alta densità, che consiste nel This task and these purposes are achieved by a process for the production of panels for the construction of furniture components and the like starting from a laminar element having a predefined thickness, laminar element consisting of material chosen from wood chipboard, composite based on medium density wood fiber, composite based on low density wood fiber and composite based on high density wood fiber, which consists of
- sottoporre detto elemento laminare ad un processo di taglio secondo dimensioni esuberando tra 0,5 e 10 mm rispetto alle dimensioni di interesse del pannello finito; - subjecting said laminar element to a cutting process according to dimensions extending between 0.5 and 10 mm with respect to the dimensions of interest of the finished panel;
- sottoporre almeno un bordo di detto elemento laminare tagliato ad una lavorazione per asportazione di truciolo atta a generare un piano inclinato in corrispondenza di detto almeno un bordo; - subjecting at least one edge of said laminar element cut to a machining by chip removal capable of generating an inclined plane in correspondence with said at least one edge;
- rivestire la faccia di detto elemento laminare, comprendendo anche la superficie di detto piano inclinato e parte delle porzioni contigue dei rispettivi bordi, con un primo foglio in materiale polimerico; - covering the face of said laminar element, also comprising the surface of said inclined plane and part of the contiguous portions of the respective edges, with a first sheet of polymeric material;
- sagomare e rifinire a misura i bordi dell'elemento laminare parzialmente rivestito; - shape and finish to size the edges of the partially coated laminar element;
- rivestire l'altra faccia di detto elemento laminare ed anche parte dei rispettivi bordi, escludendo parte della superficie di detto piano inclinato, con un secondo foglio in materiale polimerico. - covering the other face of said laminar element and also part of the respective edges, excluding part of the surface of said inclined plane, with a second sheet of polymeric material.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, del procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili secondo il trovato, illustrata a titolo indicativo e non limitativo, negli uniti disegni, in cui: Further characteristics and advantages of the invention will become clearer from the description of a preferred but not exclusive embodiment of the method for manufacturing panels for the construction of furniture components and the like according to the invention, illustrated by way of non-limiting example, in the joined drawings, in which:
la fig.1 rappresenta, in vista schematica, procedimento per la realizzazione di pannelli per la costruzione di componenti di arredo e simili secondo il trovato. Fig. 1 represents, in a schematic view, a process for manufacturing panels for the construction of furniture components and the like according to the invention.
Con particolare riferimento a tali figure è indicato globalmente con 1 un procedimento per la realizzazione di pannelli 2 per la costruzione di componenti di arredo e simili. With particular reference to these figures, the reference numeral 1 generally designates a process for manufacturing panels 2 for building furniture components and the like.
Il procedimento secondo il trovato prevede l'utilizzo di un elemento laminare avente uno spessore predefinito: tale elemento laminare 3 deve essere costituito da materiale scelto tra truciolato di legno, composito a base di fibra di legno a media densità, composito a base di fibra di legno a bassa densità e composito a base di fibra di legno ad alta densità. The method according to the invention provides for the use of a laminar element having a predefined thickness: this laminar element 3 must be made of material chosen from wood chipboard, composite based on medium density wood fiber, composite based on fiber low density wood and composite based on high density wood fiber.
Il procedimento secondo il trovato prevede una serie di fasi consecutive. The method according to the invention provides for a series of consecutive steps.
In una prima fase è necessario sottoporre l'elemento laminare 3 ad un processo di taglio secondo le dimensioni previste. In a first step it is necessary to subject the laminar element 3 to a cutting process according to the foreseen dimensions.
In particolare il taglio previsto nella prima fase dovrà risultare esuberante rispetto alle dimensioni del prodotto finito di una lunghezza (per ciascuna dimensione principale) tra 0,5 e 10 mm. In particular, the cut foreseen in the first phase must be exuberant compared to the dimensions of the finished product of a length (for each main dimension) between 0.5 and 10 mm.
Si specifica che secondo una soluzione realizzativa di indubbio interesse pratico ed applicativo, si prevede di tagliare l'elemento laminare 3 con una lunghezza ed una larghezza di circa 5 mm superiori a quelle delle rispettive dimensioni del prodotto finito (non si prevedono invece interventi per la riduzione dello spessore dell'elemento 3). It is specified that according to a realization solution of undoubted practical and applicative interest, it is envisaged to cut the laminar element 3 with a length and a width of about 5 mm greater than those of the respective dimensions of the finished product (on the other hand, no interventions are foreseen for the reduction of the thickness of the element 3).
Nel corso di una successiva seconda fase del procedimento 1 secondo il trovato è invece validamente prevista la sottoposizione di almeno un bordo dell'elemento laminare 3 tagliato ad una lavorazione per asportazione di truciolo atta a generare un piano inclinato 4 in corrispondenza di tale almeno un bordo. In the course of a subsequent second phase of the method 1 according to the invention, on the other hand, the subjecting of at least one edge of the cut laminar element 3 to a machining by chip removal capable of generating an inclined plane 4 in correspondence with said at least one edge is validly provided .
Per ottenere il piano inclinato 4 si potrà procedere ad una fresatura, ad esempio a pantografo (macchinario nel quale un tastatore segue un superficie di riferimento ed un utensile asporta materiale dal componente in lavorazione fino a riprodurre la sagoma della superficie di riferimento). To obtain the inclined plane 4, it is possible to proceed with milling, for example with a pantograph (machinery in which a feeler follows a reference surface and a tool removes material from the component being machined to reproduce the shape of the reference surface).
Si specifica che, secondo una ipotesi realizzativa, il piano inclinato 4 potrebbe avere una inclinazione di 45° rispetto alle superfici contigue; non si esclude comunque di realizzare differenti inclinazioni, forme e sagome per il medesimo. It is specified that, according to a constructive hypothesis, the inclined plane 4 could have an inclination of 45 ° with respect to the contiguous surfaces; however, it is not excluded to realize different inclinations, shapes and shapes for the same.
Una terza fase del procedimento consiste nel rivestire la faccia 5 dell'elemento laminare 3, comprendendo anche la superficie di piano inclinato 4 e parte delle porzioni contigue dei rispettivi bordi, con un primo foglio in materiale polimerico 6. A third step of the process consists in coating the face 5 of the laminar element 3, also comprising the inclined plane surface 4 and part of the contiguous portions of the respective edges, with a first sheet of polymeric material 6.
Una volta eseguito questo primo rivestimento superficiale si procederà (nel corso di una quarta fase) a sagomare e rifinire a misura i bordi dell'elemento laminare 3 parzialmente rivestito. Una quinta fase richiederà il rivestimento dell'altra faccia 7 dell'elemento laminare 3 ed anche i rispettivi bordi, escludendo parte della superficie del piano inclinato 4, con un secondo foglio 8 in materiale polimerico. Once this first surface coating has been carried out, the edges of the partially coated laminar element 3 will be shaped and finished to size (in the course of a fourth phase). A fifth step will require the coating of the other face 7 of the laminar element 3 and also the respective edges, excluding part of the surface of the inclined plane 4, with a second sheet 8 of polymeric material.
In questo modo l'elemento laminare 3 risulterà rivestito con una continuità estetica del rivestimento sulla sua faccia 5, in cui il foglio 6, rivestendo anche il piano inclinato 4 conferisce un aspetto complessivo fino ad ora non ottenibile utilizzando elementi laminari 3 del tipo di quelli elencati in precedenza. In this way, the laminar element 3 will be coated with an aesthetic continuity of the coating on its face 5, in which the sheet 6, also covering the inclined plane 4, gives an overall appearance up to now not obtainable by using laminar elements 3 of the type listed above.
In particolare si evidenzia che le fasi di rivestimento (la terza e la quinta fase del procedimento 1) possono vantaggiosamente essere eseguite esercitando una pressione di valore predefinito e mantenendo almeno un componente scelto tra il foglio in materiale polimerico 6, 8, l'elemento laminare 3 ed il pressore (proposto ad esercitare la citata pressione sul foglio giustapposto ad una faccia 5, 7 dell'elemento laminare 3 stesso) ad una temperatura di valore predefinito, superiore alla temperatura ambiente. L'applicazione dei fogli 6, 8 attraverso una azione di tipo termo-meccanico (una sorta di presso-fusione di ciascun foglio 6, 8 sulla rispettiva faccia 5, 7) garantirà una ottimale adesione di alcuni tipi di polimeri all'elemento 3. In particular, it should be noted that the coating phases (the third and fifth phases of the process 1) can advantageously be carried out by exerting a pressure of a predefined value and maintaining at least one component selected from the sheet in polymeric material 6, 8, the laminar element 3 and the presser (proposed to exert the aforementioned pressure on the sheet juxtaposed to a face 5, 7 of the laminar element 3 itself) at a temperature of predefined value, higher than the ambient temperature. The application of the sheets 6, 8 through a thermo-mechanical action (a sort of press-fusion of each sheet 6, 8 on the respective face 5, 7) will ensure optimal adhesion of some types of polymers to the element 3.
In alternativa è prevista la possibilità di accoppiare i fogli 6, 8 alle rispettive superfici 5, 7 attraverso l'interposizione di opportuni collanti o resine o polimeri termoplastici (coerenti e quindi facilmente accoppiabili con quelli che costituiscono i fogli 6, 8 e con le facce 5 e 7 dell'elemento laminare 3). Alternatively, it is possible to couple the sheets 6, 8 to the respective surfaces 5, 7 through the interposition of suitable adhesives or resins or thermoplastic polymers (coherent and therefore easily coupled with those that make up the sheets 6, 8 and with the faces 5 and 7 of the laminar element 3).
Si specifica che, con particolare riferimento ad una soluzione realizzativa di indubbio interesse applicativo, l'elemento laminare 4 di spessore predefinito è costituito da composito a base di fibra di legno a media densità (tra i 500 e gli 800 kg/m3), del tipo denominato MDF: l'elemento 4 sarà cioè preferibilmente costituito da fibre di legno finissime legate tra loro da particolari collanti e/o resine, che rendono l'insieme estremamente compatto. A differenza del truciolato o del compensato, il composito MDF si presta a essere lavorato come il legno massello rendendo così questa tipologia di legno particolarmente adatta realizzare arredi, piani e mobili di vario genere. It is specified that, with particular reference to a construction solution of undoubted application interest, the laminar element 4 of predefined thickness is made of a composite based on medium density wood fiber (between 500 and 800 kg / m3), of the type called MDF: the element 4 will preferably consist of very fine wood fibers linked together by particular glues and / or resins, which make the whole extremely compact. Unlike chipboard or plywood, MDF composite lends itself to being worked like solid wood thus making this type of wood particularly suitable for making furnishings, tops and furniture of various kinds.
Si evidenzia inoltre che il primo foglio 6 ed il secondo foglio 8 possono favorevolmente essere realizzati in un polimero preferibilmente scelto tra cloruro di polivinile, in sigla PVC, polietilene, in sigla PE, polietilene tereftalato, in sigla PET e simili. It is also pointed out that the first sheet 6 and the second sheet 8 can be favorably made of a polymer preferably selected from polyvinyl chloride, in the abbreviation PVC, polyethylene, in the abbreviation PE, polyethylene terephthalate, in the abbreviation PET and the like.
In linea generale si specifica che tutti i polimeri termoplastici potrebbero essere potenzialmente utilizzati per la realizzazione dei fogli 6 ed 8 a seconda di specifiche esigenze che potrebbero emergere relativamente alla caratteristiche del pannello 2 che si intenda realizzare. In general, it is specified that all the thermoplastic polymers could potentially be used for the realization of the sheets 6 and 8 according to specific needs that could emerge with regard to the characteristics of the panel 2 to be made.
Va evidenziato che può essere utilmente prevista una fase addizionale di giustapposizione stabile sui bordi perimetrali 9 dell'elemento 4 rivestito, i quali non risultano essere rivestiti con i rispettivi fogli polimerici 6, 8, con un nastro polimerico di finitura. It should be pointed out that an additional stable juxtaposition step can be usefully provided on the perimeter edges 9 of the coated element 4, which are not coated with the respective polymeric sheets 6, 8, with a polymeric finishing tape.
In tal modo il pannello 2 ottenuto presenterà caratteristiche estetiche del tutto similari a quelle di un componente realizzato in legno massello (l'aspetto estetico dipenderà dalla tipologia e dalle immagini riprodotte sulle superfici dei fogli 6 ed 8). In this way the panel 2 obtained will have aesthetic characteristics which are entirely similar to those of a component made of solid wood (the aesthetic appearance will depend on the type and the images reproduced on the surfaces of sheets 6 and 8).
La tutela della presente domanda si estende anche ad un pannello 2 per la costruzione di componenti di arredo e simili. The protection of the present application also extends to a panel 2 for the construction of furniture components and the like.
Tale pannello 2 secondo il trovato comprende favorevolmente un elemento laminare interno 3, avente uno spessore predefinito, costituito da materiale scelto tra truciolato di legno, composito a base di fibra di legno a media densità, composito a base di fibra di legno a bassa densità e composito a base di fibra di legno ad alta densità. Said panel 2 according to the invention favorably comprises an internal laminar element 3, having a predefined thickness, consisting of material selected from chipboard, composite based on medium density wood fiber, composite based on low density wood fiber and composite based on high density wood fiber.
Il pannello 2 comprende inoltre almeno un bordo perimetrale sagomato, provvisto di superficie inclinata 4 di raccordo tra le due facce principali 5 e 7. The panel 2 also comprises at least one shaped perimeter edge, provided with an inclined surface 4 for connecting the two main faces 5 and 7.
Il pannello 2 secondo il trovato risulterà convenientemente provvisto di un rivestimento costituito da un primo foglio 6, stabilmente accoppiato ad una sua prima faccia 5, ed un secondo foglio 8, stabilmente accoppiato ad una sua seconda faccia 7. The panel 2 according to the invention will conveniently be provided with a coating consisting of a first sheet 6, stably coupled to its first face 5, and a second sheet 8, stably coupled to its second face 7.
Il primo foglio 6 ed il secondo foglio 8 avranno vantaggiosamente i bordi terminali con disposizione preferibilmente scelta tra giustapposta (in cui tali bordi sono affacciati e combaciano, conferendo una continuità al rivestimento da essi costituito) e parzialmente sovrapposta, in corrispondenza della superficie inclinata 4 del bordo perimetrale sagomato. The first sheet 6 and the second sheet 8 will advantageously have the terminal edges with an arrangement preferably chosen between juxtaposed (in which these edges face and match, giving continuity to the coating constituted by them) and partially superimposed, in correspondence with the inclined surface 4 of the contoured perimeter edge.
L'adozione di un primo foglio 6 e di un secondo foglio 8 realizzati in un polimero termoplastico consente di realizzare una adesione ottimale di ciascun foglio all'elemento laminare 3: in particolare si segnala che saranno preferibilmente adottati fogli in cloruro di polivinile, in sigla PVC, o in polietilene, in sigla PE, o in polietilene tereftalato, in sigla PET, in quanto consentono di ottenere un prodotto finito di particolare pregio estetico. The adoption of a first sheet 6 and a second sheet 8 made of a thermoplastic polymer allows an optimal adhesion of each sheet to the laminar element 3 to be achieved: in particular, it should be noted that polyvinyl chloride sheets will preferably be used, in abbreviation PVC, or polyethylene, in the initials PE, or in polyethylene terephthalate, in the initials PET, as they allow to obtain a finished product of particular aesthetic value.
Se specifica inoltre che il primo 6 ed il secondo foglio 8 possono proficuamente presentare un aspetto di tipo preferibilmente scelto tra una superficie laccata di colore predefinito, una superficie evocante le venature di una particolare essenza di legno, una superficie disegnata/decorata e simili. If it also specifies that the first 6 and the second sheet 8 can profitably have an appearance of a type preferably chosen from a lacquered surface of a predefined color, a surface evoking the veins of a particular wood essence, a designed / decorated surface and the like.
In questo modo il rivestimento e la particolare conformazione dell'elemento 3 (dotato della superficie inclinata 4 su cui i fogli 6 e 8 sono giustapposti e/o parzialmente sovrapposti) potranno conferire al pannello 2 una finitura estetica particolarmente pregevole. In this way, the coating and the particular shape of the element 3 (equipped with the inclined surface 4 on which the sheets 6 and 8 are juxtaposed and / or partially overlapped) can give the panel 2 a particularly valuable aesthetic finish.
In particolare l'aspetto del pannello 2 potrà anche essere sostanzialmente analogo a quello di un pannello di legno massello provvisto di una faccia laccata. In particular, the appearance of the panel 2 can also be substantially similar to that of a solid wood panel provided with a lacquered face.
La tutela offerta dal presente trovato si estende anche ad un componente di arredo del tipo di un mobile, un tavolo, una mensola e simili, il quale comprenda almeno un pannello 2 secondo la rivendicazione 6. The protection offered by the present invention also extends to a piece of furniture such as a piece of furniture, a table, a shelf and the like, which comprises at least one panel 2 according to claim 6.
In particolare pannello 2 potrà costituire una parte del componente di arredo scelta tra un'anta, un montante, un fianco, un frontale, una mensola ed un ripiano. In particular, panel 2 can constitute a part of the furniture component chosen from a door, an upright, a side, a front, a shelf and a shelf.
Vantaggiosamente il presente trovato risolve i problemi esposti in precedenza, proponendo un procedimento 1 per la realizzazione di pannelli 2 per la costruzione di componenti di arredo e simili che consente di realizzare pannelli 2 con aspetto simile, ed anche confondibile, con quello del legno massello. Advantageously, the present invention solves the problems set out above, proposing a method 1 for manufacturing panels 2 for the construction of furniture components and the like which allows to produce panels 2 with a similar and even confusing appearance with that of solid wood.
Tale circostanza è molto vantaggiosa in quanto l'elemento laminare 3 utilizzato è estremamente meno costoso di un equivalente lastra in legno massello. This circumstance is very advantageous since the laminar element 3 used is extremely less expensive than an equivalent solid wood slab.
Convenientemente il procedimento 1 secondo il trovato è infatti semplice ed applicabile su tavole in materiali del tipo dell'MDF, del truciolare e simili. Conveniently, the method 1 according to the invention is in fact simple and applicable on boards made of materials such as MDF, chipboard and the like.
Favorevolmente il pannello 2 per la costruzione di componenti di arredo e simili secondo il trovato presenta caratteristiche estetiche simili a quelle del legno massello e costi inferiori rispetto al medesimo, caratteristiche che lo rendono estremamente interessante nel settore dell'arredamento. Advantageously, the panel 2 for the construction of furniture components and the like according to the invention has aesthetic characteristics similar to those of solid wood and lower costs than the same, characteristics that make it extremely interesting in the furniture sector.
Proficuamente il componente di arredo secondo il trovato presenterà quindi caratteristiche Advantageously, the furniture component according to the invention will therefore have characteristics
