DESCRIZIONE DESCRIPTION
del trovato avente per titolo: of the invention entitled:
"Procedimento atto ad ottenere, da pannelli di composto a media-densita o simili, listelli sagomati curvabili e rivestibili per mobili in genere, e listelli ottenuti con detto procedimento." "Process suitable for obtaining, from panels of medium-density composite or the like, curved and upholsterable shaped strips for furniture in general, and strips obtained with said process."
Il trovato in oggetto concerne un procedimento atto ad ottenere da pannelli pressati di materiale composto, del tipo a media densit? o simili, listelli sagomati curvabili e rivestibili, da utilizzare per bordature di finitura di piane, zoccoli o cimase, o per cornici di mobili in genere, applicabili su pannelli curvi. The present invention relates to a process suitable for obtaining from pressed panels of composite material, of the medium density type. or similar, curved and covered shaped strips, to be used for finishing edges of tops, plinths or moldings, or for furniture frames in general, applicable on curved panels.
Il trovato comprende anche gli elementi ottenuti con detto procedimento. The invention also includes the elements obtained with said process.
Le cornici curve dei mobili vengono comunemente ottenute tagliando, con la curvatura desiderata, una striscia da una tavola di massello, che viene poi sagomata con frese, per ottenere scanalature e rilievi. Poich? la cornice curva cosi ottenuta non e' rivestibile con impiallacciature o simili, nel caso di finitura con legno a vista occorre utilizzare essenze pregiate, con conseguenti danni all'ambiente e costi rilevanti. Pur con accurate lavorazioni, si possono avere molti scarti, a causa della non omogeneit?' del massello. The curved frames of furniture are commonly obtained by cutting, with the desired curvature, a strip from a solid wood board, which is then shaped with cutters, to obtain grooves and reliefs. Since? the curved frame thus obtained cannot be covered with veneers or the like, in the case of finishing with exposed wood it is necessary to use precious woods, with consequent damage to the environment and significant costs. Even with accurate processing, there can be a lot of waste, due to the non-homogeneity? ' of solid wood.
Le cornici curve vengono anche realizzate incollando e pressando in uno stampo strati sovrapposti di legno. Anche queste cornici non sono pero' rivestibili ed inoltre richiedono la preparazione di stampi di forme corrispondenti a quelle desiderate. Curved frames are also made by gluing and pressing overlapping layers of wood into a mold. However, these frames too cannot be coated and furthermore require the preparation of molds having shapes corresponding to those desired.
I listelli sagomati fino ad ora ottenuti da strisce tagliate da pannelli pressati di composto a media densit?', fresate su una superficie esterna del pannello originario, possono essere applicati solo su superfici piane, perche' non sono adeguatamente flessibili. Infatti i pannelli pressati di composto a media densit?' vengono appositamente costruiti in modo da avere adeguata rigidit?' superficiale, per il prevalente impiego al quale sono destinati (piani, fiancate di mobili, ecc). The shaped strips up to now obtained from strips cut from pressed panels of medium density compound, milled on an external surface of the original panel, can be applied only on flat surfaces, because they are not adequately flexible. In fact, the pressed panels of medium density composite? are purposely built in order to have adequate rigidity? ' superficial, for the prevalent use for which they are intended (tops, sides of furniture, etc.).
Lo scopo del presente trovato e' quello di permettere la costruzione di listelli sagomati per cornici, flessibili e rivestibili, utilizzando un comune pannello pressato di composto a media densit? , o simili. The object of the present invention is to allow the construction of shaped strips for frames, which are flexible and can be covered, using a common pressed panel of medium density compound. , or similar.
Il procedimento consiste essenzialmente nel sezionare un pannello, del tipo sopra specificato e di spessore uguale o maggiore della larghezza del listello finito, in modo da ottenere strisce che vengono successivamente fresate non sulle superfici a vista del piano originario, ma su facce perpendicolari al piano stesso, in modo da far lavorare a trazione e compressione, durante la curvatura, prevalentemente gli strati interni del materiale, che hanno minore resitenza di quelli superficiali. In tal modo viene inoltre maggiormente snervato il materiale, le cui le fibre tendono ad orientarsi in senso orizzontale, per effetto della pressatura. The procedure essentially consists in cutting a panel of the type specified above and having a thickness equal to or greater than the width of the finished strip, in order to obtain strips that are subsequently milled not on the visible surfaces of the original plane, but on faces perpendicular to the plane itself. , in order to make mainly the internal layers of the material, which have less resistance than the superficial ones, work in traction and compression during bending. In this way, moreover, the material is more yielded, the fibers of which tend to orient themselves horizontally, due to the effect of pressing.
Il profilo ottenuto dopo la fresatura pu?' essere rivestito con impiallacciatura, o con carte o pellicole di rivestimento in genere, successivamente ricoperte con vernice trasparente di finitura. Esso potrebbe pero' anche essere semplicemente laccato. The profile obtained after the milling can? be coated with veneer, or with coating papers or films in general, subsequently covered with transparent finishing varnish. However, it could also be simply lacquered.
Il listello sagomato potrebbe anche presentare una contro-sagomatura posteriore, per migliorarne le caratteristiche di flessibilit?'. The shaped strip could also have a rear counter-shaping, to improve its flexibility characteristics.
Il trovato viene ora descritto in dettaglio, facendo riferimento alle tavole di disegni allegate, che illustrano a solo titolo esemplificativo una sua poss i bi le attuazi one . The invention is now described in detail, with reference to the attached drawings, which illustrate, by way of example only, one of its possible embodiments.
La fig.l mostra come viene attualmente ottenuto un listello sagomato 1 da un pannello pressato 2 di composto a media densit? . In tal caso il listello risulta rigido, poich? , in caso di tentativo di curvatura, verrebbero essenzialmente sollecitati a trazione e a compressione gli strati superficiali del pannello, di maggiore rigidit? . In questo caso lo spessore del pannello non ? strettamente in relazione con la larghezza della cornice sagomata che si vuole ottenere. Figure 1 shows how a shaped strip 1 is currently obtained from a pressed panel 2 of medium density compound. . In this case, the strip is rigid, since? , in the event of an attempt to bend, the surface layers of the panel, of greater rigidity, would be essentially stressed by traction and compression. . In this case the thickness of the panel is not? strictly related to the width of the shaped frame to be obtained.
La f?g.2 illustra come viene ricavato un listello sagomato 1 partendo da un pannello 2 di spessore corrispondente, o eventualmente maggiore della larghezza del listello. In tal caso si ? verificato, con prove sperimentali, che il listello ottenuto pu? essere facilmente curvato: infatti le porzioni di materiale prevalentemente sottoposte a trazione e a compressione, durante la curvatura, sono quelle interne, di minore rigidit? . Figure 2 illustrates how a shaped strip 1 is obtained starting from a panel 2 of corresponding thickness, or possibly greater than the width of the strip. If so, yes? verified, with experimental tests, that the strip obtained can? be easily bent: in fact the portions of material mainly subjected to traction and compression, during bending, are the internal ones, with less rigidity? .
La fig.3 rappresenta un listello sagomato 1, la cui flessibilit? e' stata migliorata fresando una contro-sagomatura posteriore 3. Fig. 3 represents a shaped strip 1, whose flexibility? It has been improved by milling a rear counter-shaping 3.
La fig.4 mostra la possibilit? di ricavare contemporaneamente due listelli 1 e 1? da un pannello 2, di spessore pari alla somma delle larghezze dei listelli stessi. Fig. 4 shows the possibility? to obtain two strips 1 and 1 at the same time? from a panel 2, with a thickness equal to the sum of the widths of the strips themselves.
I listelli ottenuti come sopra spiegato possono essere agevolmente rivestiti e curvati, come ad esempio in fig,5, per contornare un bordo curvilineo di un piano 4. The strips obtained as explained above can be easily coated and curved, as for example in fig, 5, to surround a curvilinear edge of a plane 4.
La fig.6 mostra una cornice rettangolare 5, formata con i listelli sagomati in oggetto, la quale, per la sua flessibilit? , pu? essere applicata su un pannello curvo 6, fig.7. Fig. 6 shows a rectangular frame 5, formed with the shaped strips in question, which, due to its flexibility? , can? be applied on a curved panel 6, fig. 7.
Ovviamente i dettagli costruttivi non essenziali potrebbero anche essere diversi da quelli illustrati a solo titolo esemplificativo, senza per questo uscire dall'ambito del presente trovato. Obviously, the non-essential construction details could also be different from those illustrated by way of example only, without thereby departing from the scope of the present invention.
