DESCRIZIONE DESCRIPTION

del brevetto per Modello di Utilità of the patent for Utility Model

Il presente Modello di Utilità ha come oggetto un tubo flessibile perfezionato per conduzione d'acqua, utilizzato preferibilmente per irrigazione . The present Utility Model relates to an improved hose for water conduction, preferably used for irrigation.

La novità del tubo flessibile consiste nell 'utilizzare una maglia di filo rinforzato e una maglia di filo tessuto, con la quale si ottiene un ottimo comportamento del tubo per quanto riguarda la pressione e la resistenza alla torsione, essendo la torsione uno dei principali problemi che si verificano in questo tipo di tubi flessibili utilizzati per irrigazione, giacché essendo tubi di lunghezze considerevoli si producono torsioni nel tubo che strangolano la circolazione dell’acqua. The novelty of the flexible hose consists in the use of a reinforced wire mesh and a woven wire mesh, with which an excellent behavior of the pipe is obtained with regard to pressure and resistance to torsion, being the torsion one of the main problems that occur in this type of flexible pipes used for irrigation, since being pipes of considerable lengths, there are twists in the pipe that strangle the circulation of water.

Generalmente i tubi flessibili tradizionali si ottengono attraverso la macchina d'intrecciatura della tessitura. Traditional hoses are generally obtained through the weaving machine.

Il tubo flessibile presenta uno strato interno cilindrico dalla superficie liscia sulla quale si arrotola una maglia tessuta o intrecciata di rinforzo e uno strato esterno di copertura. The flexible hose has a cylindrical internal layer with a smooth surface on which a woven or braided reinforcement mesh and an external covering layer are rolled up.

Il tubo dell'invenzione presenta uno strato interno tubolare sul quale si arrotola un rinforzo di filo di poliester e su questo rinforzo si dispone uno strato tubolare di rivestimento sul quale anche esteriormente si dispone uno strato di maglia tessuta protetta con uno strato tubulare di rivestimento esterno. The tube of the invention has an internal tubular layer on which a reinforcement of polyester thread is rolled up and on this reinforcement a tubular coating layer is arranged on which a layer of woven mesh protected with an external tubular layer is also arranged on the outside. .

Successivamente il tubo dell'invenzione utilizza in combinazione i due processi di rinforzo in una sola realizzazione; da qui la miglior qualità, resistenza alla trazione e alla pressione che presenta il tubo dell'invenzione rispetto ad altri tubi flessibili conosciuti. Subsequently, the tube of the invention uses the two reinforcement processes in combination in a single embodiment; hence the best quality, resistance to traction and pressure that the tube of the invention presents with respect to other known flexible tubes.

I tubi flessibili vengono realizzati in materia plastica (PVC, HLFE) gomma o altri ottenuti generalmente con un processo di estrusione . The flexible pipes are made of plastic (PVC, HLFE) rubber or others generally obtained with an extrusion process.

Perché questi tubi siano più resistenti alla torsione ed alla pressione vengono coperti tradizionalmente con uno strato di filo di poliester . To make these tubes more resistant to torsion and pressure, they are traditionally covered with a layer of polyester wire.

In questa copertura i fili sono intrecciati tra di loro ottenendo una maglia uniforme. In this cover the threads are intertwined to obtain a uniform knit.

Questa copertura viene realizzata per mezzo di macchine che intrecciano e tessono simultaneamente, le quali coprono a loro volta lo strato interno del tubo. This covering is made by means of machines that weave and weave simultaneously, which in turn cover the inner layer of the tube.

L'invenzione, oltre a combinare i due sistemi con il tubo, permette di ottenere una maggior resistenza in confronto ad altri prodotti commercializzati nel mercato. The invention, in addition to combining the two systems with the tube, allows to obtain greater resistance compared to other products marketed on the market.

Successivamente, in base a quanto indicato precedentemente, il tubo dell'invenzione è flessibile perfettamente cilindrico ed è rinforzato con una maglia intrecciata di poliester che è coperta a sua volta da un microstrato e su di esso un nuovo rinforzo di poliester tessuto, dando come finitura interna un quinto strato perfettamente cilindrico. Subsequently, on the basis of what has been indicated above, the tube of the invention is flexible perfectly cylindrical and is reinforced with a braided polyester mesh which is in turn covered by a microlayer and on it a new reinforcement of woven polyester, giving as a finish inside a fifth perfectly cylindrical layer.

Questo tubo ha caratteristiche più positive per quanto si riferisce all'elasticità e torsione e con riferimento a tubi normalmente fabbricati con maglie che si commercializzano nel mercato. This tube has more positive characteristics as regards elasticity and torsion and with reference to tubes normally manufactured with meshes that are marketed on the market.

Il tubo dell'invenzione è costituito da: - Uno strato interno composto da PVC plastificato. The tube of the invention consists of: - An internal layer made of plasticized PVC.

- Uno strato di filo rinforzato di poliester. - A layer of polyester reinforced wire.

Un microstrato composto da PVC plastificato. A microlayer made of plasticized PVC.

- Uno strato di filo tessuto di poliester. - Uno strato esterno composto da PVC. - A layer of polyester woven thread. - An outer layer composed of PVC.

Per comprendere più facilmente non solo la costituzione, ma anche l'uso proprio del tubo dell'invenzione, si riporta di seguito un esempio pratico di realizzazione, essendo tale esecuzione puramente enunciativa e in nessun caso limitativa della medesima, tutto questo così e come viene mostrato nel disegno accluso nel quale si rappresenta una prospettiva del tubo flessibile 1 dell 'invenzione. In order to understand more easily not only the constitution, but also the proper use of the tube of the invention, a practical example of realization is reported below, since this execution is purely enunciative and in no case limiting it, all this as and how it is shown in the accompanying drawing which shows a perspective of the flexible tube 1 of the invention.

Il tubo flessibile 1 è costituito da uno strato interno tubolare 2 di PVC per il cui esterno si dispone uno strato di rinforzo 3 di filo di poliester che dispone una maglia intrecciata sulla quale va disposto un microstrato di rivestimento coassiale 4 di PVC. The flexible pipe 1 is constituted by an internal tubular layer 2 of PVC, on the outside of which there is a reinforcing layer 3 of polyester thread which has a braided mesh on which a coaxial coating microlayer 4 of PVC is arranged.

Su questo microstrato va disposto un nuovo rinforzo che definisce uno strato 5 di maglia tessuta di filo di poliester e come finitura esterna uno strato perfettamente cilindrico 6 di rivestimento esterno di PVC. A new reinforcement is placed on this microlayer which defines a layer 5 of woven polyester wire mesh and as an external finish a perfectly cylindrical layer 6 of external PVC coating.

Descritta sufficientemente la natura dell'invenzione, così come la forma di realizzazione pratica, si deve far constare che le disposizioni anteriormente indicate e rappresentate nel disegno accluso sono suscettibili a modifiche di particolari sempre che non alterino il principio fondamentale. Having sufficiently described the nature of the invention, as well as the practical embodiment, it must be pointed out that the provisions previously indicated and represented in the attached drawing are susceptible to modifications of details as long as they do not alter the fundamental principle.
