DISPOSITIVO E METODO PER LA REALIZZAZIONE DI UN PROFILO RINFORZATO E PROFILO COSÌ OTTENUTO DEVICE AND METHOD FOR THE REALIZATION OF A REINFORCED PROFILE AND PROFILE SO OBTAINED
DESCRIZIONE DELL'INVENZIONE DESCRIPTION OF THE INVENTION
La presente invenzione s'inquadra nel settore dell’estrusione e dei profili estrusi e si riferisce ad un dispositivo e ad un metodo per la realizzazione di un profilo rinforzato ed al profilo così ottenuto, particolarmente adatto alla realizzazione di infissi, imposte, persiane profili strutturali, parti di mobili ed arredi e simili. The present invention is part of the extrusion and extruded profiles sector and refers to a device and a method for making a reinforced profile and to the profile thus obtained, particularly suitable for making frames, shutters, shutters, structural profiles , parts of furniture and furnishings and the like.
Sono noti metodi di realizzazione di profili rinforzati che prevedono l’inserimento di rinforzi metallici longitudinali nel materiale. Uno svantaggio di tali profili consiste nel fatto che risultano di complessa utilizzazione nelle fasi di preparazione, montaggio e messa in opera. Methods of making reinforced profiles are known which involve the insertion of longitudinal metal reinforcements in the material. A disadvantage of these profiles consists in the fact that they are complex to use in the stages of preparation, assembly and installation.
Sono anche noti metodi di realizzazione di profili rinforzati che prevedono una prima fase di preparazione del rinforzo, di tipo fibroso e flessibile, che viene impregnato a caldo con un materiale plastico ed una seconda fase di estrusione del profilo con inglobamento del rinforzo pre-impregnato. Methods for producing reinforced profiles are also known which provide for a first step of preparing the reinforcement, of the fibrous and flexible type, which is hot impregnated with a plastic material and a second step of extrusion of the profile with incorporation of the pre-impregnated reinforcement.
Uno svantaggio di tali metodi e dei dispositivi noti consiste nel fatto che sono molto complessi, richiedono molto spazio e sono di difficile messa a punto. A disadvantage of these methods and known devices is that they are very complex, require a lot of space and are difficult to set up.
Altro svantaggio consiste nel fatto che non si prestano ad essere applicati ed attuati in impianti di tipo preesistente. Another disadvantage consists in the fact that they do not lend themselves to being applied and implemented in pre-existing plants.
Uno scopo della presente invenzione è quello di proporre un dispositivo ed un metodo per la realizzazione di un profilo rinforzato che siano semplici, affidabili e di facile attuazione. An object of the present invention is to propose a device and a method for making a reinforced profile which are simple, reliable and easy to implement.
Altro scopo è di proporre un dispositivo adatto ad essere installato, con poche ed economiche modifiche, anche in impianti preesistenti per renderli atti ad attuare il metodo dell’invenzione. Another purpose is to propose a device suitable to be installed, with few and inexpensive modifications, even in pre-existing systems to make them suitable for implementing the method of the invention.
Ulteriore scopo è di proporre un profilo in materiale termoplastico rinforzato avente elevata stabilità dimensionale in modo che, anche dopo lunghe esposizioni a condizioni ambientali sfavorevoli, presenti variazioni delle dimensioni, principalmente di quella longitudinale, molto piccole o nulle. A further object is to propose a profile made of reinforced thermoplastic material having high dimensional stability so that, even after long exposure to unfavorable environmental conditions, there is very little or no size variation, mainly of the longitudinal one.
Ulteriore scopo è di proporre un profilo in materiale termoplastico rinforzato con cordoni o nastri di materiale fibroso di rinforzo aventi sezioni trasversali circolari, ovali, rettangolari, piatte o pressoché di ogni altra forma. A further object is to propose a profile in thermoplastic material reinforced with cords or ribbons of reinforcing fibrous material having circular, oval, rectangular, flat cross-sections or almost any other shape.

The reinforced profile object of the present invention and made by means of the device described above, comprises a body in plastic material of the profile 101 preferably made of thermoplastic material such as for example PVC and incorporating at least one reinforcement means 102 having a cross section of circular, oval shape, rectangular, polygonal or curved and made of bare or dressed or intertwined fibers of glass or other inorganic or organic material.
Un vantaggio della presente invenzione è di fornire un dispositivo ed un metodo per la realizzazione di un profilo rinforzato che siano semplici, affidabili e di facile attuazione. An advantage of the present invention is to provide a device and a method for making a reinforced profile which are simple, reliable and easy to implement.
Altro vantaggio è di fornire un dispositivo adatto ad essere installato, con poche ed economiche modifiche, anche in impianti preesistenti per renderli atti ad attuare il metodo dell’invenzione. Another advantage is to provide a device suitable for installation, with few and inexpensive modifications, even in pre-existing systems to make them suitable for implementing the method of the invention.
Ulteriore vantaggio è di fornire un profilo in materiale termoplastico rinforzato con cordoni o nastri di materiale fibroso di rinforzo aventi sezioni trasversali circolari, ovali, rettangolari, piatte o pressoché di ogni altra forma. A further advantage is to provide a profile in thermoplastic material reinforced with cords or ribbons of reinforcing fibrous material having circular, oval, rectangular, flat cross-sections or almost any other shape.
Ulteriore vantaggio è di fornire un profilo in materiale termoplastico rinforzato avente elevata stabilità dimensionale anche dopo lunghe esposizioni a condizioni ambientali anche sfavorevoli. A further advantage is to provide a profile in reinforced thermoplastic material having high dimensional stability even after long exposures to even unfavorable environmental conditions.
