Sono noti cassonetti per serramenti avvolgibili del tipo comunemente denominato tapparella. Essi nel passato venivano realizzati in legno ma attualmente vengono realizzati in lamiera metallica piegata ed aggraffata oppure in alluminio estruso od anche con pannelli ottenuti in materiale plastico estruso e reciprocamente agganciati. Boxes for roller shutters of the type commonly referred to as roller shutter are known. In the past they were made of wood but currently they are made of folded and crimped metal sheet or extruded aluminum or even with panels obtained from extruded plastic material and mutually hooked.

E' stato anche proposto di realizzare i cassonetti formati da pannelli formati ciascuno da due fogli di lamiera metallica tra i quali è interposto uno strato di materiale espanso, detti pannelli essendo reciprocamente congiunti fra loro lungo i bordi a contatto. It has also been proposed to make the boxes formed by panels each formed by two sheets of metal plate between which a layer of expanded material is interposed, said panels being mutually joined together along the edges in contact.

Scopo dell'invenzione è di realizzare un pannello per cassonetti per serramenti avvolgibili che presenti le stesse caratteristiche dei pannelli metallici con rivestimento interno ma che possa essere ottenuto in modo più semplice e con un costo ridotto. The object of the invention is to produce a panel for boxes for roller shutters which has the same characteristics as the metal panels with internal lining but which can be obtained in a simpler way and with a reduced cost.

Altro scopo dell'invenzione è di realizzare un pannello che presenti una buona stabilità dimensionale e resistenza alla deformazione rispetto ai pannelli in plastica. Another object of the invention is to provide a panel which has good dimensional stability and resistance to deformation with respect to plastic panels.

Tali scopi ed altri che risulteranno dalla descrizione che segue sono raggiunti secondo l'invenzione con un procedimento per realizzare pannelli per cassonetti caratterizzato dal fatto di comprendere le fasi di: These objects and others that will emerge from the following description are achieved according to the invention with a process for making panels for boxes characterized in that it comprises the steps of:

- profilatura di un nastro di lamiera per ottenere un profilato continuo, - profiling of a sheet metal strip to obtain a continuous profile,

- iniezione di una schiuma poliuretanica all'interno del profilato, - injection of a polyurethane foam inside the profile,

- applicazione di una pellicola deformabile al di sopra di detta schiuma, - application of a deformable film on top of said foam,

- deformazione di detta schiuma secondo un contorno definito, - deformation of said foam according to a defined contour,

- polimerizzazione della schiuma fino all'indurimento, e - polymerization of the foam until hardened, e

-taglio del profilato per ottenere il pannello delle desiderate dimensioni. - cutting of the profile to obtain the panel of the desired dimensions.

La presente invenzione viene qui di seguito ulteriormente chiarita in una sua preferita forma di pratica realizzazione riportata a scopo puramente esemplificativo e non limitativo con riferimento alla allegata tavola di disegni in cui: The present invention is further clarified hereinafter in a preferred embodiment thereof reported for purely illustrative and non-limiting purposes with reference to the attached drawing table in which:

la figura 1 mostra in vista schematica una attrezzatura per effettuare il procedimento secondo l'invenzione, e Figure 1 schematically shows an apparatus for carrying out the process according to the invention, and

la figura 2 rappresenta un pannello per formare cassonetti. figure 2 represents a panel for forming boxes.

Come si vede dalle figure il procedimento secondo l'invenzione comprende sostanzialmente un aspo 2, di avvolgimento di un nastro di lamiera 4, posto a monte di una macchina profilatrice 6 alla cui uscita è prevista una stazione 8 di iniezione di schiuma poliuretanica. As can be seen from the figures, the method according to the invention substantially comprises a reel 2, for winding a strip of sheet metal 4, placed upstream of a profiling machine 6 at the outlet of which a polyurethane foam injection station 8 is provided.

A valle di detta stazione è previsto un aspo 10 di avvolgimento di una pellicola 12 in alluminio o plastica ed una unità 14 di sagomatura. Detta unità 14 è costituita da due trasportatori sovrapposti a nastro, 16 e 18 con il trasportatore inferiore 16 a superficie piana per sostenere e far avanzare il profilo e con il trasportatore superiore 18 a superficie sagomata conformemente alla forma da far assumere allo schiumato allo stato non indurito. Downstream of said station there is a reel 10 for winding an aluminum or plastic film 12 and a shaping unit 14. Said unit 14 consists of two superimposed belt conveyors, 16 and 18 with the lower conveyor 16 having a flat surface to support and advance the profile and with the upper conveyor 18 having a shaped surface in accordance with the shape to be taken by the foamed product in the untreated state. hardened.

Al'uscita del trasportatore è previsto un tunnel 20 di polimerizzazione alla cui uscita è prevista una tranciatrice 22. At the exit of the conveyor a polymerization tunnel 20 is provided, at the exit of which a shearing machine 22 is provided.

Il procedimento secondo l'invenzione prevede che il nastro di lamiera 4 venga svolto dall'aspo 2 e fatto passare attraverso la macchina profilatrice dove esso viene sagomato secondo la forma desiderata. All'interno del The method according to the invention provides that the sheet metal strip 4 is unwound by the reel 2 and passed through the profiling machine where it is shaped according to the desired shape.

profilato così ottenuto viene iniettata schiuma poliuretanica 21 sulla quale viene successivamente distesa la pellicola 12 proveniente dall'aspo 10. Il profilato viene fatto avanzare dal nastro 16 all'interno della unità di sagomatura dove il trasportatore superiore impartisce la forma desiderata al rivestimento interno schiumato. Il profilato viene quindi inviato al tunnel di polimerizzazione 18 dove lo schiumato indurisce e successivamente il profilato viene tagliato ad ottenere il pannello 24 della lunghezza desiderata. Da quanto detto risulta chiaramente che il procedimento secondo l'invenzione presenta numerosi vantaggi ed in particolare: - consente di ottenere pannelli in modo più semplice, - presenta un minor costo di impianto così come un prodotto finito a costo ridotto.
