Sin embargo, hasta el momento no se tiene conoci¬ miento de la existencia de un procedimiento para la fabrica¬ ción de bolsas de plástico para basura o similares que esté dotado de las características señaladas como idóneas.However, to date there is no knowledge of the existence of a procedure for the manufacture of plastic garbage bags or the like that is endowed with the characteristics indicated as suitable.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El procedimiento para la fabricación de bolsas de plástico para basura que la invención propone, constituye por sí mismo una evidente novedad dentro del área industrial en la cual se va a utilizar, ya que a partir del mismo, no solamente se logra disponer de un procedimiento que permite la fabricación de bolsas o tiras de bolsas de unas características apropiadas y perfectamente determinadas a partir del reciclado de materias plásticas constitutivas del producto empleado como materia prima, si no que todas las bolsas obtenidas son adaptables a cualquier situación y consideración, y al mismo tiempo permite multiplicar por dos el número de producto obtenido en una sola línea de fabricación, estando el producto obtenido dotado de unas características particulares que potencian sustancial- mente los productos similares introducidos hasta el mo ento en el mercado, debido a que este producto está provisto de unas características propias e inherentes al mismo.The procedure for the manufacture of plastic garbage bags that the invention proposes, constitutes by itself an obvious novelty within the industrial area in which it will be used, since from it, not only is it possible to have a procedure that allows the manufacture of bags or strips of bags of appropriate and perfectly determined characteristics from the recycling of plastic materials constituting the product used as raw material, if not all the bags obtained are adaptable to any situation and consideration, and at the same time allows to multiply by two the number of product obtained in a single manufacturing line, the product obtained being endowed with particular characteristics that substantially enhance the similar products introduced up to the moment in the market, because this product is provided of its own characteristics and inherent to it.
De forma más concreta, el procedimiento paraMore specifically, the procedure for
HOJA SUSTITUIDA la fabricación de bolsas de plástico para basura objeto de la invención, está constituido a partir de la utilización de una máquina convencional que permite la fabricación normalizada de bolsas de plástico con la incorporación de fuelles laterales, pudiendo igualmente sustituirse la existencia de los dos fuelles laterales por uno solo, sa¬ liendo al exterior debidamente plegadas incorporado el citado fuelle lateral, o dos fuelles que originados por los laterales, ocupan toda la superficie del cuerpo interno con excepción de la línea central.SUBSTITUTED SHEET The manufacture of plastic garbage bags object of the invention, is constituted from the use of a conventional machine that allows the standard manufacturing of plastic bags with the incorporation of side bellows, and the existence of the two side bellows can also be substituted by only one, when the aforementioned lateral bellows are incorporated to the outside, or two bellows that originate from the sides, occupy the entire surface of the internal body with the exception of the central line.
En esta máquina se ha incorporado, en la línea central de salida, un elemento situado apropiadamente y posicionado de forma pertinente, permite su actuación longi- tudinal sobre el fabricado, y realiza de forma paulatina dos líneas de soldadura lateral y en la línea central situa¬ da entre las áreas de soldadura laterales una línea de corte, consiguiendo consecuentemente que el fabricado que se extrae por este procedimiento de fabricación quede divi- dido en dos productos idénticos, determinados por la línea de corte que actúa a continuación de la línea de soldadura, siendo la línea de soldadura de actuación doble, ya que se realiza una soldadura en la zona interna, y otra poste¬ riormente en la zona cortada, con objeto de que no existan bordes inconexos en esta rama del fabricado.In this machine, an appropriately positioned and positioned element is incorporated into the central outlet line, allows its longitudinal action on the manufactured one, and gradually performs two lateral welding lines and in the central line located ¬ it gives a cutting line between the lateral welding areas, consequently ensuring that the fabrication that is extracted by this manufacturing process is divided into two identical products, determined by the cutting line that acts next to the welding line , the double acting welding line being, since a welding is carried out in the internal zone, and another subsequently in the cut zone, so that there are no unconnected edges in this branch of the manufactured one.
De esta forma, se va realizando la obtención paulatina de dos tiras de bolsas, las cuales son enrolladas posteriormente, disponiendo en los laterales opuestos de una línea de plegado, lo cual determina en el momento de su utilización que en la zona inferior o fondo de la bolsa se presenten unas líneas de refuerzo, determinadas por la propia soldadura realizada en la etapa de soldado del fondo, situada alineada en paralelo con la línea de precor- tado, actuando la línea de soldadura en colaboración conIn this way, the gradual obtaining of two strips of bags is carried out, which are subsequently rolled up, having on the opposite sides a folding line, which determines at the time of use that in the lower area or bottom of The bag is provided with reinforcement lines, determined by the welding itself carried out in the bottom welding stage, located aligned in parallel with the pre-cut line, the welding line acting in collaboration with
HOJA SUSTITUIDA el fuelle para determinar una serie de líneas de refuerzo en el fondo de la propia bolsa.SUBSTITUTED SHEET the bellows to determine a series of reinforcement lines at the bottom of the bag itself.
Lógicamente, si no se realiza la incorporación de los fuelles en el momento de la configuración del tubo del film que determina la existencia de la materia principal a partir de la cual se realiza la línea de bolsas, la obten¬ ción de bolsas se verá sensiblemente mermada en su configu¬ ración final.Logically, if the bellows are not incorporated at the time of the configuration of the film tube that determines the existence of the main material from which the bag line is made, the obtaining of bags will be noticeable diminished in its final configuration.
