MECHA PARA ARTEFACTO PIROTECNICODATE FOR PIROTECHNICAL ARTIFACT
DESCRIPCIONDESCRIPTION
Objeto de la invencionObject of the invention
La presente invencion se refiere a una mecha para artefacto pirotecnico con una configuration tal que facilita el procedimiento de fabrication de la propia mecha y asegura el perfecto funcionamiento de la mecha cuando dicha mecha se prende.The present invention relates to a fuse for pyrotechnic artifact with a configuration that facilitates the manufacturing process of the wick itself and ensures the perfect functioning of the wick when said wick is ignited.
Problema tecnico a resolver y antecedentes de la invencionTechnical problem to solve and background of the invention
Las mechas conocidas en el estado de la tecnica estan formadas por un hilo trenzado de algodon, que recibe el nombre de estopln introducida en un conducto que habitualmente es de papel.The wicks known in the state of the art are formed by a braided cotton thread, which is called a cheesecloth inserted in a conduit that is usually made of paper.
El estopln esta formado por una serie de filamentos de algodon, que se entrecruzan entre si y se impregnan con una materia explosiva en un bano y al que se realiza una operation de secado posterior, en la que el conjunto se cura para formar el estopln conocido.The cheesecloth is formed by a series of cotton filaments, which intersect with each other and are impregnated with an explosive material in a bath and to which a subsequent drying operation is performed, in which the whole is cured to form the known cheesecloth. .
Una de las mayores utilizaciones del estopln es formar una traca, cuando se emplea junto con una pluralidad de petardos. Para formar la traca el citado estopln se introduce en el conducto de papel que alsla el estopln del exterior dando lugar a una especie de canalization de papel con el estopln dentro de la canalization, de manera que se van colocando los diferentes petardos pinchados en la canalizacion para prender el estopln y que la ignition avance prendiendo la pluralidad de petardos que va encontrando dicha ignition en su avance por el citado estopln. De esta manera se prenden los diferentes petardos en el orden en que se van pinchando en la canalizacion formando una traca de las comunmente conocidas.One of the biggest uses of the rapier is to form a traca, when used together with a plurality of firecrackers. To form the berth, the aforementioned rapier is introduced into the paper duct that allays the rapier from the outside, giving rise to a kind of paper canalization with the rapier inside the canalization, so that the different punctured firecrackers are placed in the canalization. to ignite the estopln and that the ignition advances igniting the plurality of firecrackers that this ignition finds in its advance by the mentioned estopln. In this way the different firecrackers are lit in the order in which they are punctured in the canalization forming a traca of the commonly known.
Con las tracas as! fabricadas, ocurre en ocasiones, que el estopln en su procedimiento de fabricacion no se ha impregnado bien de materia explosiva y una vez prendido se apaga en el interior del conducto, con lo que la traca queda sin explotar o con una explosion a medias.With the freckles ace! manufactured, it happens sometimes, that the rapier in its manufacturing process has not been impregnated well with explosive matter and once turned on it is turned off inside the duct, so that the traca is left unexploded or with a half explosion.
La fabricacion del estopln que va por el interior de la canalizacion es una tarea complicada ya que dicho estopln debe impregnarse de material explosivo y para su secado posterior se situa en unas columnas de secado donde el estopln se cuelga y se somete bien a un proceso de secado mediante aire caliente o con cualquier otro agente que aporte el calorThe manufacture of the lining that goes through the interior of the canalization is a complicated task since said lint must be impregnated with explosive material and for its subsequent drying it is located in drying columns where the lint is hung and is well subjected to a process of drying by hot air or with any other agent that provides heat

necesario para el secado del estopln, o bien a temperatura ambiente.necessary for drying the cheesecloth, or at room temperature.
Este procedimiento de fabrication del estopln presenta el inconveniente de la manipulation del citado estopln cuando se pasa de la etapa de impregnation a la etapa de secado, ya que el estopln se encuentra impregnado de material explosivo y una mala manipulacion en el paso a la etapa de secado puede hacer que el estopln quede mal impregnado y no resulte en una explosion del citado estopln como se desea.This procedure of manufacture of the lint presents the disadvantage of the manipulation of the mentioned lint when it is passed from the impregnation stage to the drying stage, since the lint is impregnated with explosive material and a bad manipulation in the step to the stage of Drying can cause the gasket to be impregnated poorly and not result in an explosion of the said gasket as desired.
Adicionalmente a lo anterior la tarea de conformar la mecha mediante la introduction del estopln por el interior de la canalization es una tarea tediosa que implica un trabajo manual que resulta poco efectivo y en ocasiones resulta en una rotura de la canalizacion que limita la longitud de la mecha fabricada.In addition to the above, the task of shaping the wick by introducing the cheesecloth inside the canalization is a tedious task that involves manual labor that is ineffective and sometimes results in a rupture of the pipeline that limits the length of the manufactured wick
As! pues la mecha objeto de la invention trata de afrontar todos los inconvenientes que presentan las mechas conocidas en el estado de la tecnica as! como los problemas ocasionados en el procedimiento de fabricacion de las mechas conocidas en el estado de la tecnica.Ace! since the wick object of the invention tries to face all the inconveniences that the known wicks have in the state of the art as! as the problems caused in the manufacturing process of the wicks known in the state of the art.
La principal novedad de la mecha objeto de la invencion es que el material explosivo (habitualmente polvora) se impregna unicamente en un lado de la lamina. Ello es importante porque, a diferencia de la mecha actual, conformada por hilos de algodon impregnados en todo su perlmetro por la polvora, esta mecha laminar posee una de las caras de la lamina soporte sin material explosivo, lo que mejora sustancialmente las operaciones de trasiego, loglstica, secado, etc. del producto, en su proceso de fabricacion.The main novelty of the wick object of the invention is that the explosive material (usually powder) is impregnated only on one side of the sheet. This is important because, unlike the current wick, made up of cotton threads impregnated throughout its perimeter by the powder, this laminar wick has one of the faces of the support sheet without explosive material, which substantially improves the transfer operations , logistic, drying, etc. of the product, in its manufacturing process.
