Definitions

  • the present invention relates to improvements introduced in the invention patent number 200102600 relative to a method for obtaining a continuous mesh tubular for forming bags for fruit and vegetable products and the like, especially applicable to obtaining a continuous tubular that alternately transversely webbed mesh bands with plastic bands and reinforcing ribbons located on the inner face of said tubular, which act, together with said laminar bands, as reinforcement and support for different types of graphic prints.
  • the tubular obtained by the procedure described in the patent No. 200102600 is constituted from four longitudinal bands, two lateral mesh bands and two plastic lamellar bands, disposing each other in alternate positions being partially overlapped, specifically the bands being located laminar externally to the mesh side bands.
  • the union between the laminar bands and the mesh sidebands was carried out by heat welding, this manufacturing process has the following disadvantages: the heat applied to the mentioned union causes that sometimes the laminar band is wrinkled and that the graphic impressions are deformed and the letters are illegible.
  • the procedure is limited to the use of certain materials for the mesh bands and the lamellar bands, since for the safe union of the materials to occur, it is necessary that both have similar melting points, and therefore it is not allowed The union of materials of different nature and melting point such as: polypropylene, polyethylene, paper, ... etc.
  • the production speed of the tubular is quite slow since it is necessary to wait for the molten material to cool, to be able to manipulate the tubular without causing deformations.
  • the objective of the present improvements is to solve the exposed problems, making that the union between the laminar bands and the mesh side bands can be done by simple gluing, as well as by heat welding, for which the introduction of additional tapes located is necessary on the inner face of the free ends of the lateral mesh bands, whose main mission is to reinforce the union between the laminar bands and the mesh side bands.
  • the present invention relates to improvements introduced in the invention patent No. 200201660 relative to a procedure for obtaining a continuous mesh tubular for forming bags for fruit and vegetable products and the like and tubular obtained by said method , whose tubular is constituted by four bands, two laminar and two other mesh, one and the other arranged in alternate positions, partially overlapping along strips that join together, additionally providing the aforementioned laminar bands four reinforcing tapes located in the vicinity of both free ends of each of the mesh bands, being attached to its inner face and to the laminar bands.
  • a sandwich arrangement is defined in each of four the joints that exist in the tubular, formed by three layers a first layer constituted the end of the corresponding laminar band, an intermediate layer constituted by the end of the mesh band and a third layer constituted by the corresponding tape, said arrangement makes the bags constituted from the tubular defined in the present invention to be of great resistance and that a greater verticality or rigidity of the tubular is caused causing the storage of bags full of products be more secure and stable.
  • the placement of the reinforcing belts coinciding with the handle that incorporates each bag makes the fixing of said handles more solid than if they were only attached to the laminar bands, thus preventing the detachment of said handles during the transport of the bags and therefore that the transported product is damaged.

  • the continuous improved tubular mesh for the formation of bags for fruit and vegetable products object of the present invention is constituted from four bands two 1-1 'laminar bands and two other mesh bands 2- 2 ', one and the other arranged in alternating positions, partially overlapping along strips that join together.
  • the tubular has four reinforcing bands 3-3 'and 4-4', located in the vicinity of both free ends of the mesh bands, specifically the bands 3 and 3 'are located in the free ends of the mesh band 2 and the ribbons 4 and 4 'on the free ends of the mesh band 2', joining its inner face and at the same time to the laminar bands 1 - 1 ⁇
  • Said laminar bands 1-1 'each one of them will be arranged above one of the free ends of the two mesh bands 2-2' by gluing, that is to say the laminar band 1 will be placed on the ends 5 and 6 of the mesh bands 2-2 'respectively and the laminar strip 1' will be placed on the ends 5 'and 6' of the mesh bands 2-2 'respectively, in Figure 1 the arrangement described can be clearly seen.
  • the mesh bands 2-2 ' are embedded in a plate 7 that forms part of the bench, surrounding the edges of said plate in order to continue adopting its "C" shape, by its part of the reinforcing tapes 3 and 4 are initially placed on a second plate 8 of smaller width connected to the previous one so that they are located internally to the mesh bands, the tapes 3 and 4 are above said second plate 8 and the 3 'and 4' tapes are below it.
  • rollers 9-9 ' are placed, at a certain distance from the bench, through which the laminar bands 1 and 1' pass respectively, at that moment four glue applicators, two of them 10 located above the tubular and two of them 10 'below it, apply glue on the inner face of the lamellar bands 1-1' respectively.
  • Each of the laminar bands 1-1 ' are driven towards a pressure roller 11-11' respectively, by means of intermediate rollers 12-12 'that tension said laminar bands, said pressure rollers tighten to each laminar band, whose inner face is previously impregnated with glue, against the corresponding mesh band and in turn against the reinforcing tapes located below the free ends of each laminar mesh, achieving that the union reinforced by the mentioned tapes occurs, between the laminar bands and the free ends of the mesh bands I defend a closed tubular of great resistance, whose sides are normally extruded mesh and whose front are laminar band Ia which is capable of being printed with commercial and informative reasons.
  • the union achieved between the laminar and mesh bands is of great resistance, which is due to the fact that the mesh band is placed in a position intermediate between the corresponding laminar band and the reinforcing tape and due to its mesh structure the glue deposited on the laminar layer passes through the holes of the mesh band and manages to reach the tape, making it in a single step of Pressed, by means of the pressure rollers 11-11 ', the three layers are joined, defining a sandwich structure in which the mesh band layer is retained between the corresponding laminar band layer and the layer constituted by the reinforcing tape .

Abstract

Ce procédé d'obtention d'un tube en continu de maille pour la formation de sacs pour produits hortofruiticoles et analogues est constitué de quatre bandes, dont deux sont stratifiées et deux sont en maille, toutes étant disposées dans des positions alternées, partiellement superposées sur les franges qui s'assemblent. Le tube dispose aussi de quatre bandes de renfort placées à proximité des deux extrémités libres de chaque bande en maille; elles sont assemblées sur leur face interne entre elles et avec les bandes stratifiées par collage.
