Definitions

  • the present specification refers to a patent of invention relating to a process for the manufacture of plastic garbage bags, whose obvious purpose is to allow the manufacture of a plurality of plastic bags, applicable as garbage bags or waste , which are subsequently distributed in rolls, in which a certain amount of them is contemplated, the manufacture of the bags being made from a single manufacturing stage, being subsequently provided with a welding line and central cut, which consequently allows its division into antagonistic and twin bags, having in the corresponding area a transverse weld that delimits, on the one hand the background area and the precut area and at the same time, due to the special configuration of This soldier zone in collaboration with a lateral folding zone, results in the existence in the lower zone of the bag as well as Nfigured, of a reinforcement area determined by the shape of the bag itself, which substantially enhances the use of the bag, and the manufacture of plastic garbage bags can also be carried out on a unit manufacturing line, with all the guarantees obtained in the configuration contemplated in the double manufacturing.
  • SUBSTITUTED SHEET This invention has its application within the industry dedicated to the manufacture of plastic bags.
  • the bags may be provided with or without side bellows.
  • plastic bags are manufactured in an appropriate way to the constitutive dimensions, consequently using a mouthpiece that performs the corresponding fusion and the relevant formation, using appropriate means, regardless of the texture of the plastic with which they are made, color, configuration, quality, etc., etc.
  • SUBSTITUTED SHEET with a procedure that would allow the obtaining of two similar manufactured products from the use of a single production line, obtaining those manufactured gradually in accordance with their manufacturing with the simple incorporation of a welding and cutting line,
  • the manufactured ones can be provided with a wide internal fold that, in collaboration with the transversal welding, results in the existence of a reinforcement area or line.
  • 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.
  • 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.
  • SUBSTITUTED SHEET the bellows to determine a series of reinforcement lines at the bottom of the bag itself.
  • Figure number 1 Shows a perspective view of a manufacturing made by the process according to the invention, relative to a procedure for the manufacture of plastic garbage bags, in a first embodiment of bags in a double line , provided with bellows.
  • Figure number 2.- Shows a view in fontral elevation of the object represented in figure number 1.
  • Figure number 3. Shows a perspective view of a unit object obtained from the stages developed and represented in the previous figures, detached from the roll in which it is distributed.
  • Figure number A.- Shows a perspective view
  • SUBSTITUTED SHEET The object represented in figure number 3, obtained by the procedures represented in figures numbers 1 and 2, full of garbage or filth, properly closed and appreciating in this figure, the reinforcements generated by transverse welding and the performance of the fold.
  • Figure number 5 Finally shows a perspective view of a possible embodiment according to the invention, which results in the configuration of a bag provided with a central fold with reinforcements at the bottom, obtained by the welding line made transverse entity, being able to obtain this manufacturing line in a unitary way instead of using a film that is split in half by having bellows in the lateral areas.
  • the procedure for the manufacture of plastic garbage bags is constituted from the corresponding stages of the treatment of the product used for the manufacture of the film, regardless of its origin characteristics, which gives as a result, the obtaining of a continuous film that adopts the tubular configuration, emerging from the relevant formation nozzle, which optionally according to the first embodiment, may be provided with two lateral folds, being subsequently subjected to an action of folding and going outside configured as a quadruple sheet, existing in the central area a double sheet line, which is used for the performance of a welding-cutter element, which generates two central welding lines, subject to same time to the film, a cutting action and a second double welding action, which makes the union
  • this device that acts for the formation of the double lateral welding line, central cutting line and double welding line of the side fringes of both bags, manages to multiply the manufactured ones obtained linearly by two.
  • the bags are subjected to the pre-cut and shortcut welding stage of transverse action, which determines the bottom and separation areas of the bags incorporated in cylinders, in which they are distributed and cut into a specific number of bag units, subsequently leaving for a packaging machine, in which the external package is incorporated for later sale.
  • FIG. 1 it can be seen in figure number 1 as the procedure for the manufacture of plastic bags (1), it is constituted from a plastic tube subjected to the action of the lateral elements that form the folds (5) of two bags (2) and (2 '), separated by a double welding, cutting and double welding line (3), determining the formation of independent rolls (5), in which it incorporates a certain number - Combination of units in bags, (2) or (2 '), each of these bags being provided with a side fold (6), a mouth (8), and a transverse welding line (A) and precut ( A 1 ) which determines in collaboration with the fold (6) the existence of reinforcement lines (7) at the bottom of the bag (2) or (2 '), as
  • SUBSTITUTED SHEET shown in figure number A, obtaining on the one hand that the bags (2) or (2 '), obtained separated from the existing bag below, of similar characteristics by a welding line (A) and precut (A') f are properly formed so that at the time of use, thanks to the fold (6) and the welding line (A), the existence in the rear area of the reinforcement lines (7) is determined, shown in figure number A as stated above.
  • the film tube used to obtain the bags is provided with a fold similar to that shown in figure number 3, and as in all cases It will be distributed in a roll (5) separating the bags from each other by a welding line (A), which forms the bottom reinforcements, and a pre-cut line

Abstract

Procédé de fabrication de sacs en plastique pour les ordures, consistant en la configuration sur un cylindre en plastique flexible de deux plis latéraux (6) qui occupent pratiquement toute la surface interne à l'exception d'une zone centrale située longitudinalement et sur laquelle, après obtention du film de plastique préformé, on effectue deux lignes de soudure latérales, une coupure centrale (3) et ensuite deux soudures latérales, ce qui permet de diviser le produit obtenu en deux éléments similaires (2, 2').
