Definitions

  • the present invention relates to an improved process allowing the production of knitted articles, usable either as, as reinforcements, or associated with other materials, in particular incorporated inside a resin, natural or synthetic rubber in view of making flat or shaped "composite” or “laminate” articles (molded for example), in order to strengthen them and / or give them specific characteristics.
  • a woven structure and a knitted structure In general, the choice between a woven structure and a knitted structure depends on the intended application, the knitted structures having the essential advantage of being able to be easily deformed, which makes them particularly suitable for making articles. molded. On the other hand, this deformability makes them totally unsuitable for applications in which it is necessary to have a transverse blocking.
  • tubular reinforcements of constant or variable diameter, and this in different dimensions, for example to produce artides such as pipes, belts, tires, or even conical, oval, ball-shaped structures ....
  • the knitted articles are divided into two large families, namely those obtained according to the technique known as "tossed mesh”, and the technique known as “picked mesh” implemented either on circular looms or on rectilinear looms.
  • the jersey thread is always distributed on the same needle bed, while for the production of tubular elements, the two needle beds are worked alternately, the row of jersey being made so that, according to a predetermined frequency, a needle of the needle bed on which the jersey is formed is not supplied with thread in order to allow the transfer of a stitch formed on the corresponding needle of the opposite needle bed.
  • the process according to the invention makes it possible to use any type of filiform material as a weft thread which does not mesh with the needles.
  • any type of filiform material as a weft thread which does not mesh with the needles.
  • Figures 1 and 2 schematically illustrate the manner in which the knitted structures according to the invention are produced, namely respectively a flat structure (Figure 1) and a tubular structure ( Figure 2), these knits being produced on a rectilinear loom with discarded stitches, double needle bed, and which allows the transfer of stitches from the needles of the front needle bed (AV) to those of the rear needle bed (AR), and vice versa.
  • the knitted structures according to the invention are produced from two threads (F) and (T), one meshing with the needles in a jersey weave and the other not meshing with said needles.
  • the cross arrow indicates the direction of movement of the carriage; moreover, the references (T) and (F) used to designate the threads are positioned on the side of the needle bed where the thread is located awaiting distribution or after distribution to the needles.
  • the knitting cycle or ratio is carried out on three round trips of the yarn distribution carriage and control of the movements of the needles.
  • phase 1 a jersey row on the needles of a needle bed (AR in the case present) with wire F which is put on hold at the end of this row on the right of the machine.
  • the thread F forms a jersey knit on a single needle bed, the back needle in the present case, said thread being distributed over all the needles.
  • the rows of jersey are made alternately on the front and the back needle and, in this case, the distribution of the thread is not done on all the needles but according to a predetermined frequency, for example three, five, seven needles ..., supplied with thread for a non-supplied needle, the transferred stitch is preferably the central stitch of the sequence.
  • This first row of jersey being formed when the carriage returns (phase 2), a selection of jersey stitches is transferred to the second needle bed (front).
  • the second row of jersey (phase 4) is made on the same needle bed as the first row, whereas in the case of a tubular article as illustrated in FIG. 2, the yarn distribution is done on the front bed and transfer on the back bed, on needles that have not been supplied with yarn during the first row of jersey knit.
  • the knits in accordance with the invention can be produced on all types of looms with straight throws, allowing a transfer of the stitches from the front bed to the rear bed (or vice versa) and which, preferably, make it possible to vary the width of knitting by increases and decreases, thus obtaining flat or tubular shaped structures.
  • the non-meshed wire being trapped between the flanges of the knitted stitches, is maintained in a practically rectilinear manner and therefore makes it possible to obtain a transverse (or diametral) blocking.
  • This thread can be of any kind and size, since it is simply distributed in a rectilinear manner and is never engaged with the needles.
  • Such knits can be used in many applications, in particular as mentioned in the preamble to make reinforcements for reinforcing composite articles.
  • Such knits could of course be used in other sectors where it is desired to have tubular, cylindrical or variable-shaped structures, for example conical.
  • the presence of the straight wire inside the knitted fabric also allows the porosity of the latter to be modulated at will by varying the weft density.
