Definitions

  • the present invention relates to a canvas bag, a canvas for the manufacture of said bag and a method of manufacturing the said canvas.
  • woven canvas bags especially synthetic material such as polypropylene or polyethylene in particular.
  • Some, called big bags in circles interested, are used for transport, handling and storage of the most diverse goods, but others smaller bags in the shape of a rectangular pillow well filled are also used for larger quantities small. How large and small bags are made is very close and the manufacturers are essentially the same. All these bags are well known in port places, rail and road, in particular.
  • the purpose of the present invention is to provide a bag in synthetic material whose texture makes it stackable better than normal synthetic bags, but without involve son of different qualities.
  • the invention relates to a method of manufacturing, on a circular or flat loom, of a canvas with warp threads and weft threads, characterized in what we use in the weft at least one ribbon wire and in this apply a weaving tension lower than that of other wefts, ribbons or not, of weft, lower tension chosen so that said ribbon wire forms, on the surface of the canvas, protruding loops with at least one edge vivid, so that the friction coefficient of the canvas in is increased, in particular the canvas / canvas coefficient.
  • the invention also relates to a canvas suitable for the manufacture of bags and comprising chain threads and weft yarns, characterized in that at least one of the yarns weft is a ribbon yarn and in that said ribbon yarn forms, protruding loops on the surface of the canvas presenting minus a live slice, so the coefficient of canvas friction is increased, especially the canvas / canvas coefficient.
  • the invention also relates to a bag for transport and storage of bulk goods, characterized in that it is achieved, at least in part, by means of said canvas.
  • Figure 1 shows a piece of canvas according to invention and illustrates the willful, willful and ordered, caused by the application of the process according to the invention.
  • Figure 2 illustrates a detail of the piece of canvas shown in figure 1.
  • Figure 3 illustrates a detail of a thread of the canvas shown in Figures 1 and 2.
  • the process consists of voluntarily disrupting the loom to weave, that is to say to use it according to parameters which know perfectly well that they are not optimal, in theory everything at least.
  • FIG 2 which illustrates the preferred variant canvas and bag according to the invention
  • a canvas woven 1 with a thread which is in the form of a thin ribbon or strip which means that the weaving constitutes a sort of checkerboard.
  • Such sons are from of extruded films cut into thin ribbons using knives. Once cut into ribbon, the wire is rewound to then be used on a loom.
  • each loop 2 has a fairly sharp edge 3, which acts as a scraper, which considerably increases the sliding resistance.
  • the fabric 1 produced according to the process just described has the particularity of a overall regular weaving, however, with an anomaly (or more if you reduce the tension of several shuttles) which consists in the repetition at regular intervals of a succession of protuberances 2 which correspond to the wire (s) which winds more freely and with more amplitude than the others.
  • the canvas has a coefficient of higher friction than a traditional fabric with the same supplies and on the same loom.
