DESCRIZIONE DESCRIPTION

dell’ invenzione industriale dal titolo: of the industrial invention entitled:

“Supporto tessile sintetico per guaine bituminose, per la copertura di tetti.” "Synthetic textile support for bituminous membranes, for roofing."

La presente invenzione si riferisce ad un supporto tessile sintetico per guaine bituminose, per la copertura di tetti. The present invention refers to a synthetic textile support for bituminous sheaths, for covering roofs.

È noto nelle tecniche di copertura di tetti l'utilizzo di guaine bituminose, aventi un supporto tessile sintetico. Il supporto tessile sintetico consta di due falde non tessute di fiocco di poliestere o di fibre continue. Tra le due falde è interposto materiale di rinforzo di vario genere che va da fili di vetro a velo di vetro, a velo di fibre di poliestere con filamenti corti discontinui e così via. The use of bituminous sheaths, having a synthetic textile support, is known in roof covering techniques. The synthetic textile support consists of two non-woven layers of polyester staple or continuous fibers. Reinforcing material of various kinds is interposed between the two flaps, ranging from glass yarns to glass fleece, to polyester fiber fleece with short discontinuous filaments and so on.

Nel brevetto EP 0862667, a nome della Richiedente, si illustra un supporto tessile sintetico consistente di due strati di falda non tessuta di fibre di poliestere, tra i quali è interposta una pluralità di filamenti continui di rinforzo, realizzati con fili di poliestere, disposti in parallelo uno rispetto all'altro, nella direzione longitudinale del supporto tessile. Patent EP 0862667, in the name of the Applicant, illustrates a synthetic textile support consisting of two layers of non-woven layer of polyester fibers, between which a plurality of continuous reinforcing filaments are interposed, made with polyester threads, arranged in parallel to each other, in the longitudinal direction of the textile support.

Si ottiene in questo modo un supporto tessile sintetico, che risolve sia il problema dello stiramento trasversale del prodotto durante la fase d'impregnamento di bitume, sia il problema di assicurare un'adeguata resistenza della guaina bituminosa all'escursione termica che la copertura può subire. In this way, a synthetic textile support is obtained, which solves both the problem of the transversal stretching of the product during the bitumen impregnation phase, and the problem of ensuring adequate resistance of the bituminous sheath to the thermal excursion that the roof can undergo. .

Tuttavia un supporto così realizzato ha come limite il numero di filamenti che possono essere inseriti tra le due falde. However, such a support has as a limit the number of filaments that can be inserted between the two flaps.

Infatti, il numero di filamenti che possono essere utilizzati non può essere superiore ad una certa quantità, in quanto sussistono problemi d'insufficienza di spazio fisico per le teste di estrusione dei filamenti stessi. In fact, the number of filaments that can be used cannot exceed a certain quantity, as there are problems of insufficient physical space for the extrusion heads of the filaments themselves.

Inoltre l'inserimento dei fili di rinforzo rappresenta una complicazione per il processo produttivo e l'apparecchiatura utilizzata. Furthermore, the insertion of the reinforcing threads represents a complication for the production process and the equipment used.

In vista dello stato della tecnica descritto, scopo della presente invenzione è quello di ovviare ai problemi della tecnica nota. In view of the state of the art described, the object of the present invention is to obviate the problems of the known art.

In accordo con la presente invenzione, tale scopo è raggiunto mediante un supporto tessile sintetico per guaine bituminose, comprendente un primo ed un secondo strato di falda a filamento continuo, caratterizzato dal fatto di comprendere inoltre tra detto primo e secondo strato di falda un terzo strato di falda costituita da filamenti continui disposti nella direzione longitudinale di detto supporto tessile. In accordance with the present invention, this object is achieved by means of a synthetic textile support for bituminous sheaths, comprising a first and a second continuous filament layer, characterized in that it also comprises a third layer between said first and second layer. flap consisting of continuous filaments arranged in the longitudinal direction of said textile support.

Grazie alla presente invenzione è possibile realizzare un processo di fabbricazione in cui le tre falde, costituenti nel loro complesso la copertura per tetti, sono maggiormente integrate tra loro. Thanks to the present invention it is possible to carry out a manufacturing process in which the three pitches, constituting the roof covering as a whole, are more integrated with each other.

Grazie alla presente invenzione è possibile realizzare un processo di fabbricazione delle falde di copertura più resistente agli stress termici e agli stress di trazione rispetto ai processi dell'arte nota. Thanks to the present invention it is possible to realize a manufacturing process of the roofing flaps more resistant to thermal stresses and tensile stresses with respect to the processes of the known art.

Grazie alla presente invenzione si ottiene un processo di fabbricazione delle falde di copertura che risulta essere più semplice da realizzarsi rispetto ai processi dell'arte nota. Thanks to the present invention, a manufacturing process of the roofing flaps is obtained which is simpler to carry out than the processes of the known art.

Le caratteristiche ed i vantaggi della presente invenzione risulteranno evidenti dalla seguente descrizione dettagliata di una sua forma di realizzazione pratica, illustrata a titolo di esempio non limitativo negli uniti disegni, nei quali: The characteristics and advantages of the present invention will become evident from the following detailed description of a practical embodiment thereof, illustrated by way of non-limiting example in the accompanying drawings, in which:

la figura 1 mostra schematicamente una forma realizzativa del processo di produzione del supporto tessile secondo la presente invenzione; Figure 1 schematically shows an embodiment of the production process of the textile support according to the present invention;

la figura 2 mostra schematicamente il supporto tessile in una vista in pianta secondo la presente invenzione; Figure 2 schematically shows the textile support in a plan view according to the present invention;

la figura 3 mostra il supporto tessile in sezione lungo la linea III - III di figura 2. figure 3 shows the textile support in section along the line III - III of figure 2.

Secondo quanto schematizzato in figura 1 una prima falda 1 a filamenti continui 2 è confezionata per estrusione di un polimero poliestere fuso tramite una prima serie di teste di estrusione A e deposta su un nastro di trasporto 3. According to what is schematised in Figure 1, a first continuous filament flap 1 2 is packaged by extrusion of a molten polyester polymer through a first series of extrusion heads A and placed on a conveyor belt 3.

Con eguale procedimento si ottengono anche una seconda falda 5 ed una terza falda 6, quest'ultima con filamenti continui 7 disposti in direzione longitudinale, interposta tra detta prima falda 1 e detta seconda falda 5. With the same procedure, a second flap 5 and a third flap 6 are also obtained, the latter with continuous filaments 7 arranged in the longitudinal direction, interposed between said first flap 1 and said second flap 5.

In particolare la falda 5 è ottenuta per estrusione dal medesimo polimero fuso tramite una seconda serie di teste di estrusione B, così come la falda 6 è ottenuta tramite estrusione dello stesso o diverso polimero fuso per mezzo di una terza serie di teste di estrusione C. In particular, the pad 5 is obtained by extrusion from the same molten polymer through a second series of extrusion heads B, just as the pad 6 is obtained by extrusion of the same or different melted polymer by means of a third series of extrusion heads C.

In questo modo si ottiene un supporto tessile multistrato 4 (mostrato nelle figure 1 e 2), costituito dalla sovrapposizione delle tre falde, rispettivamente 1, 6 e 5. In this way a multilayer textile support 4 is obtained (shown in Figures 1 and 2), consisting of the overlapping of the three flaps, respectively 1, 6 and 5.

Il supporto tessile secondo l'invenzione è quindi costituito da due strati di falda 1 e 5 di filamento continuo, tra cui è interposto a guisa di sandwich una terza falda 6 realizzata con i medesimi materiali delle altre due falde 1 e 5 o con materiale diverso, ma comunque ancora a filamento continuo, disposto stavolta nella direzione longitudinale. The textile support according to the invention is therefore constituted by two layers of flaps 1 and 5 of continuous filament, between which a third flap 6 is interposed in the manner of a sandwich, made with the same materials as the other two flaps 1 and 5 or with different material , but still with a continuous filament, this time arranged in the longitudinal direction.

In questo modo si ottiene un supporto tessile multistrato che è maggiormente omogeneo rispetto alle realizzazioni note, e può essere realizzato con caratteristiche e forme differenti rispetto a quelli noti. In this way, a multilayer textile support is obtained which is more homogeneous with respect to known embodiments, and can be made with different characteristics and shapes than known ones.

Inoltre con l'interposizione di detta terza falda 6 si ha una maggiore densità di filamenti, così da fornire una resistenza del supporto multistrato superiore a quanto previsto nell'arte nota. Furthermore, with the interposition of said third layer 6 there is a greater density of filaments, so as to provide a resistance of the multilayer support higher than that envisaged in the known art.

Infine un supporto siffatto è ottenibile con un processo e un'apparecchiatura più semplice rispetto a quanto previsto nell'arte nota, perché le serie di teste A, B e C necessarie alla realizzazione del complesso multistrato presentano le medesime caratteristiche tecniche. Finally, such a support can be obtained with a simpler process and apparatus than that envisaged in the known art, because the series of heads A, B and C necessary for the realization of the multilayer assembly have the same technical characteristics.

Il supporto tessile multistrato secondo la presente invenzione serve per la formazione di supporti per guaine bituminose per la copertura di tetti. The multilayer textile support according to the present invention is used to form supports for bituminous sheaths for covering roofs.
