DESCRIPCIÓN DESCRIPTION
FUNDA DE PROTECCIÓN FLEXIBLE Y PROCEDIMIENTO DE FABRICACIÓN.FLEXIBLE PROTECTION CASE AND MANUFACTURING PROCEDURE.
Objeto de Ia invenciónObject of the invention
La presente invención se refiere a una funda de protección flexible y procedimiento de fabricación, destinada principalmente a Ia protección térmica de substratos longitudinales y su acomodación al lugar de instalación.The present invention relates to a flexible protection sheath and manufacturing process, mainly intended for the thermal protection of longitudinal substrates and their accommodation to the installation site.
Antecedentes de Ia invención.Background of the invention.
En muchos sectores industriales y de construcción, se utilizan tubos y fundas de protección de mazos de cables y conductos de fluidos, por ejemplo en Ia fabricación de automóviles. Estas fundas pueden estar realizadas por elementos tubulares de tejido de punto que permiten una flexibilidad adecuada y Ia utilización de materiales resistentes al calor y al rozamiento y de propiedades aislantes necesarias para realizar estas funciones.In many industrial and construction sectors, tubes and sheaths of cable harnesses and fluid conduits are used, for example in the manufacture of automobiles. These covers can be made of tubular knitting elements that allow adequate flexibility and the use of heat and friction resistant materials and insulating properties necessary to perform these functions.
Así, ya son conocidas fundas que presentan una configuración general tubular, abierta longitudinalmente, con una sección transversal a modo de espiral y que están conformadas por unos hilos tejidos entre sí. Estos tejidos están constituidos por tejidos de punto en máquinas de calada o de tricotado. Esta funda permite Ia introducción lateral de los substratos, por ejemplo cables o tubos a proteger, y tiene cierta flexibilidad para su colocación a Io largo de las curvas y codos del recorrido donde se va alojar. Sin embargo existe el problema de que las fundas se realizan con un punto excesivamente tupido para tener una resistencia elevada, pero a cambio, dicha funda es difícil de doblar o curvar. A su vez, si Ia funda está tejida con un punto que permite una flexibilidad mayor, resulta que no tiene el cuerpo suficiente para mantener en su interior los cables o tubos a guardar.Thus, covers are already known which have a general tubular configuration, longitudinally open, with a spiral cross-section and which are formed by woven threads. These fabrics are made up of knitted fabrics in openwork or knitting machines. This cover allows the lateral introduction of the substrates, for example cables or tubes to be protected, and has some flexibility for placement along the curves and elbows of the path where it is to be housed. However, there is the problem that the covers are made with an excessively thick point to have a high resistance, but in return, said cover is difficult to bend or bend. In turn, if the sheath is woven with a point that allows greater flexibility, it turns out that it does not have enough body to keep inside the cables or tubes to be stored.
Un ejemplo de estos tubos está descrito en Ia patente ES2158763 por "Elemento textil de fibras que contienen silicio y procedimiento para mejorar su estabilidad térmica", en Ia que se describe un elemento textil recubierto de una emulsión de silicona, Ia cual utiliza para su recubrimiento Ia impregnación y curado a una temperatura adecuada, consiguiéndose así un elemento textil con una gran resistencia al desgaste. Descripción de Ia invenciónAn example of these tubes is described in the patent ES2158763 for "Textile element of fibers containing silicon and process to improve its thermal stability", in which a textile element coated with a silicone emulsion is described, which it uses for its coating The impregnation and curing at a suitable temperature, thus achieving a textile element with great wear resistance. Description of the invention
La funda de protección flexible y el procedimiento de fabricación, objeto de esta invención, presentan unas particularidades técnicas destinadas a conseguir una protección térmica de substratos longitudinales, y que, además, presenta una flexibilidad, adaptabilidad y facilidad para curvarse mejoradas.The flexible protection sheath and the manufacturing process, object of this invention, have technical particularities intended to achieve thermal protection of longitudinal substrates, and which, in addition, have improved flexibility, adaptability and ease of bending.
En efecto, Ia funda comprende un tejido de punto por urdimbre en máquinas tipo Raschel, con hilo de fibra de vidrio, de fibra de cuarzo, de fibra de sílice, de fibra mineral y/o de fibra metálica. Se ha previsto que dicho tejido se pueda realizar en Ia máquina Raschel utilizando dos barras o tres barras de pasadores y sus variantes estructurales.In fact, the cover comprises a warp knitted fabric in Raschel type machines, with fiberglass, quartz fiber, silica fiber, mineral fiber and / or metal fiber yarn. It is envisioned that said fabric can be made in the Raschel machine using two bars or three pin bars and their structural variants.
Incluso se puede combinar en el mismo tejido zonas realizadas con porciones a dos hilos y porciones a tres hilos, configurando zonas de mayor diámetro y zonas de menor diámetro, si se estima necesarioEven areas made with two-wire portions and three-wire portions can be combined in the same fabric, configuring zones of larger diameter and areas of smaller diameter, if deemed necessary
La galga de las agujas para Ia formación del tejido puede ser de 4 a 32 agujas por pulgada. A su vez Ia densidad de mallas puede comprender de 3 a 20 mallas en 10 milímetros de longitud.The gauge of the needles for tissue formation can be from 4 to 32 needles per inch. In turn, the density of meshes can comprise from 3 to 20 meshes in 10 millimeters in length.
El procedimiento de fabricación de dicha funda comprende los pasos siguientes: tisaje del tejido de Ia funda en máquina del tipo Raschel, - enrollado transversal del tejido de Ia funda en espiral, conformación del tejido de Ia funda para que mantenga su estructura tubular.The manufacturing process of said sheath comprises the following steps: weaving of the fabric of the sheath in machine of the Raschel type, - transverse winding of the fabric of the spiral sheath, conformation of the fabric of the sheath so that it maintains its tubular structure.
Este tisaje del tejido se puede realizar mediante simple fontura o doble fontura y en máquina circular, obteniéndose así un tejido, ya sea en forma de cinta o tubular, que no presenta cuerpo ni consistencia como para mantener los substratos o cables en su interior y que es necesario estabilizar y darle consistencia. En caso de que Ia cinta de tejido sea tubular se procede a un cortado previo del tejido para configurar Ia estructura en espiral.This weaving of the fabric can be done by simple font or double font and in a circular machine, thus obtaining a fabric, either in the form of a tape or tubular, which does not have a body or consistency to keep the substrates or cables inside and that It is necessary to stabilize and give consistency. If the fabric tape is tubular, a previous cut of the tissue is carried out to configure the spiral structure.
La conformación de Ia funda, en Ia que el tejido de punto gana cuerpo, estabilidad y consistencia, puede realizarse por diferentes medios, tales como: Calentamiento del tejido, para reordenar las fibras de forma más estable. Impregnado el tejido de Ia funda con resinas o emulsiones de siliconas que favorecen su resistencia al desgaste. Utilizando hilos de fibra de vidrio del tipo torcido, que son más resistentes al deshilado por fricción y reduciendo Ia velocidad de urdido de Ia máquina o, laminando sobre el tejido diferentes materiales plásticos y/o metálicosThe conformation of the sheath, in which the knitting gains body, stability and consistency, can be carried out by different means, such as: Heating of the tissue, to rearrange the fibers in a more stable way. Impregnated the fabric of the case with resins or emulsions of silicones that favor its resistance to wear. Using twisted type fiberglass threads, which are more resistant to friction fraying and reducing the speed of warping of the machine or, rolling on the fabric different plastic and / or metallic materials
