Definitions

  • the present invention relates to an improvement made in the production of perforated bags making it possible to provide packaging for the storage, transport of various products and in particular of bulk products, such as food products (fruits, vegetables, etc.).
  • perforated bags are used, in the form of a closed pocket on three of its sides and open on the fourth, to allow the placement of the products and which is then closed after filling.
  • the bag is in the form of a continuous chain which is unrolled in front of the filling assembly, so that its open side is arranged opposite this zone, each bag being closed after filling and the said bags then being separated from each other along their connecting zone before being evacuated.
  • no gauze is meant the technique which, compared to a conventional warp and weft fabric, consists not only of moving the warp threads relative to the weft threads to make their connection, but also to move the warp threads with respect to each other, two by two, so that one of the so-called “tower threads” passes alternately on either side of the other thread called “warp thread”", the weft being trapped and being blocked between these two threads, which makes it possible to obtain an openwork fabric the days of which are perfectly defined, the warp threads being unable to slide relative to the weft threads.
  • Such a weaving technique of the "gauze” type has been known for a very long time and essentially consists in adapting the looms so that the warp threads can not only receive vertical movements to form the crowd, but also transverse movements to bind them. between them two by two.
  • so-called "two-body” assemblies equipped with so-called “gauze” type meshes are used for the control of the warp threads, the best known being those sold by the company GROB.
  • each body consists of two heddle frames which alternately control a "gauze” mesh through which passes a warp thread.
  • the present invention aims to remedy these drawbacks and relates to an improvement to the process which is the subject of the aforementioned Belgian patent making it possible, as mentioned above, to produce a fabric on a conventional loom equipped with a mechanism for controlling warp threads according to a "gauze" weave by producing a double fabric made up of two plies spaced apart from each other, said plies being linked to each other by respective interweaving of the warp and weft threads which compose them along the selvedges and also being intermittently linked, at determined spaces, over their entire width also by respective interlacing of the weft and warp threads which compose them.
  • connection of the two sheets woven along one of the selvedges will be designated by the expression “longitudinal connection” and that carried out at regular intervals in the width direction of the fabric, by the expression “transverse bond”.
  • the improved process according to the invention is characterized in that a conventional weaving loom is used equipped with a dobby ensuring the control of four bodies not of gauze mounted head to tail (two bodies above the warp threads, the two others below), each body consisting of two frames which alternately control a "gauze" mesh through which passes a warp thread, the supply of warp threads being obtained from a single food roller.
  • the control of the bodies not of gauze is carried out in such a way that if we consider a weave ratio in the warp direction which is of four threads, that we form an upper layer using two of these threads , one forming a chain wire, the other the lathe wire, and a lower layer with the other two, one forming the chain wire, the other the lathe wire and that, in the areas of connection, the thread of turn of the upper ply and the thread of turn of the lower ply come to cross each other around the wefts forming a strip of monolayer fabric.
  • a weaving loom which comprises, as shown schematically in FIG. 1, a supply of warp threads (1) (in the following the description, the warp threads will be designated by this reference (1) assigned an index a, b, c, d corresponding to a weave ratio) and a weft feed (2).
  • the fabric obtained is returned to (3).
  • the frames (6) are, in accordance with the invention, eight in number and are grouped respectively in the form of two upper bodies designated by the general reference (7) and two lower bodies designated by the general reference (8). In each body, the frames are grouped two by two, frames referenced (7a) and (7b) for the upper body (7) and (8b, 8c) for the lower body (8), and allow alternately to control a mesh " gauze "(9a, 9b, 9c, 9d) inside which pass the warp threads (1a, 1b, 1c, 1d) respectively.
  • the chain wire (1a) passes through the mesh (9a) of the upper body controlled by the two frames (7a)
  • the wire (1b) passes through the mesh (9b) of the lower body controlled by the two frames (8b )
  • FIG. 6 illustrates how the upper gauze fabric is made, Figure 7 how the lower fabric is formed and Figure 8 how the warp threads work to make the intermediate bonding area.
  • SC warp direction
  • FIG. 5a it can clearly be seen that in the central part, the warp and weft threads form two superimposed layers spaced from each other respectively (11) and (12) and, on either side of these spaced plies, the warp and weft threads are interconnected to form connecting zones (13,14) constituted by a monolayer fabric.
  • a rosary is obtained in the form illustrated in FIG. 3, that is to say made up of a succession of pockets (20a, 20b, 20c, 20d), each comprising two spaced sides (11,12) an airy fabric with gauze weave, these pockets being linked together in the weft direction (ST) by continuous strips of fabric (13,14 ). Furthermore, along one of the selvedges, for example the straight selvedge, the warp and weft threads work to form a monolayer fabric (15).
