La solución clásica a los problemas de perforación anteriormente citados consiste en la disposición de elementos metálicos, generalmente de forma laminar, en unos casos monopieza y en otros a base de láminas debidamente interrelacionadas, generalmente recubiertas para ocultar su presencia. Esta solución clásica presenta una problemática que afecta a aspectos muy variados, tales como complejidad de montaje, dificultad de adaptación a la superficie a proteger, elevado peso, etc.The classic solution to the problems of drilling mentioned above consists of the provision of metallic elements, generally of laminar form, in some cases single piece and in others based on sheets properly interrelated, usually coated to hide your presence. This classic solution presents a problem that it affects very varied aspects, such as mounting complexity, difficulty adapting to the surface to be protected, high weight, etc.
Tratando de obviar este problema se viene utilizando desde hace tiempo tejidos anti-perforación a base de aramidas, como por ejemplo el kevlar, de manera que los tejidos actúan como soporte para las aramidas, que son las que realmente generan el efecto barrera, bien pegadas a los tejidos o bien formando sándwich con los mismos.Trying to ignore this problem is coming using fabrics for a long time aramid-based anti-perforation, as per example the kevlar, so that the tissues act as support for aramids, which are the ones that really generate the effect barrier, either glued to the tissues or forming a sandwich with the same.
Estos tejidos resultan también caros por los materiales que participan en los mismos y por su complejidad de fabricación, presentando un grado de adaptabilidad que todavía deja mucho que desear.These tissues are also expensive for the materials that participate in them and because of their complexity of manufacturing, presenting a degree of adaptability that still leaves Much to be desired.
Existen otras soluciones en las que se combinan diferentes materiales con también diferentes características, que se alejan aun más de los objetivos perseguidos en este ámbito, la simplicidad del producto, el bajo costo y su fácil aplicación.There are other solutions that combine different materials with also different characteristics, which move further away from the objectives pursued in this area, the product simplicity, low cost and easy application.
El tejido anti-perforación que la invención propone constituye un notable avance tecnológico en este campo, más concretamente una solución de bajo costo, enorme simplicidad, con gran facilidad de adaptación a cualquier superficie a proteger, muy útil y simple en su aplicación y permitiendo además la utilización integral del producto.The anti-perforation fabric that the invention proposes constitutes a remarkable technological advance in this field, more specifically a low cost, huge solution simplicity, with great ease of adaptation to any surface to be protected, very useful and simple in its application and also allowing the integral use of the product.
Para ello y de forma más concreta el tejido anti-perforación que la invención propone esta constituido a partir de una pluralidad de capas de tejido de poliéster, solidarizadas entre sí mediante capas intermedias a base de látex, EVA o poliuretano que actúan como ligante o adhesivo para las capas de tejido.For this and more specifically the fabric anti-perforation that the invention proposes this constituted from a plurality of tissue layers of polyester, solidarity with each other through intermediate layers of latex, EVA or polyurethane that act as a binder or adhesive for the layers of tissue.
Dichas capas de tejido de poliéster tienen un espesor comprendido entre 0,6 y 0,8 mm, la fijación de las mismas se lleva a cabo a una temperatura comprendida entre 140 y 160°C, y con una presión a su vez comprendida entre 8 y 12 Kilos.Said layers of polyester fabric have a thickness between 0.6 and 0.8 mm, fixing them it is carried out at a temperature between 140 and 160 ° C, and with a pressure in turn between 8 and 12 Kilos.
En el ámbito preferente de aplicación de la invención, la obtención de plantillas de seguridad para calzado, en el sándwich constitutivo de dicha plantilla se utilizan de cinco a seis capas de tejido de poliéster, para la obtención de un sándwich de espesor comprendido entre 3,7 y 4 mm, que ofrece una resistencia a la perforación del orden de 110 Kg.In the preferred scope of the invention, obtaining safety insoles for footwear, in the sandwich constituting said template are used from five to six layers of polyester fabric, to obtain a sandwich thickness between 3.7 and 4 mm, which offers resistance to the drilling of the order of 110 Kg.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
