Definitions
- the present invention relates to a method for connecting along a line, at least two blanks.
- the present invention aims to overcome these drawbacks.
- water jet means any jet of fluid likely to generate the same results or results of the same order.
- the fibrous material is an integral part of at least one of said exterior blanks.
- This outer blank may in particular include at at least one layer of fiber mat and / or at least one layer of a fiber cloth.
- said fibrous material can be lined with at least one other layer of another material.
- the fibrous material can be placed inside and said jet of water projected onto said other material, or placed outside and said jet of water projected onto said fibrous material.
- the material fibrous is fed continuously as the displacement of the water jet, and is simultaneously secured by this jet of water to said blank and embedded in said others blanks.
- Figures 1a and 1b illustrate the implementation case of the simplest invention, where a blank of fibrous material such as a fabric or mat 1 is "sewn" onto a substrate 2.
- the blanks of materials 1 and 2 are first put in contact, then a nozzle 3 for projecting a water jet 4 is brought above the assembly thus obtained, on the side of the blank 1, at the start of a connection line to be obtained between the blanks, or tablecloths, 1 and 2.
- the nozzle 3 is then moved so that the water jet 4 follows the planned connection line.
- the water jet strikes the fibers of the material 1 and drives them, in their providing part of its kinetic energy, in contact with blank 2. Because of this energy, the fibers penetrate into the material 2.
- the power of the water jet is however adjusted by so that the fibers, while penetrating into the substrate, remain linked to the blank 1. These fibers thus ensure the connection between the blanks 1 and 2 along the planned connecting line.
- the fabric or the mat 1 is thus "sewn", along the connecting line, such a line being represented in the figure 1b.
- jet diameters (nozzle 3) of of the order of 0.15 mm were suitable, with pressures of the order from 1000 to 4000 bar and jet displacement speeds between 25 and 400 mm / s.
- each parameter must be chosen between two limits, one where the connection is not made, and the other where the blanks are cut by the violence of the jet.
- the principle is the same as before, except that the blank 1 of fibrous material is here doubled on the outside of a layer 5, especially of any suitable plastic such as, for example, a foam.
- the assembly consisting of layers 1 and 5 is placed against the blank 2 and the water jet 4 is directed against the layer 5.
- the water jet crosses, at least locally, layer 5 of so that the fibers of the blank 1 ensure the connection between the blanks 2 and 5.
- FIG. 3a and 3b A variant is shown in Figures 3a and 3b where the layer 5 is replaced by a two-layer structure. This last one is made of a plastic sheet 10, for example foam, bonded, for example by calendering, to a protective sheet 11. The assembly is assembled as previously to substrate 2.
- FIG. 5 it provides the connection between a blank 30 of plastic, and a composite blank 31, consisting of a fiber mat 32, foam 33, and fabric 34 pre-assembled anyway suitable.
- the mat 32 is opposite of the blank 30.
- the jet 4 is applied on the side of the fabric 34. Fibers of this last therefore cross foam 33 and mix with certain fibers of mat 32 to become embedded in the blank material 30. Along the line of displacement of the nozzle, the fabric 34 is therefore pressed against the blank 30 by crushing the foam 33 and mat 32. This results in a "style line" 35, a sort of false saddle stitching. Two such parallel lines are shown in Figure 5b.
- FIG. 6 illustrates another embodiment in which the fibrous bonding material 40 is not part of a blanks to be assembled, namely blanks 41 and 42, for example of plastic.
- the material 40 is here brought under the nozzle 3, for example in the form of a wire, a wick or a ribbon of mat, from a reel 43.
- material 40 is fed at the speed of advance of the nozzle 3, so that its fibers penetrate and become embedded in the material of the blanks 41 and 42, ensuring the connection of the latter as in the previous embodiments.

Abstract
Description
- amener lesdits flans au contact les uns des autres;
- provoquer la solidarisation d'une matière fibreuse à au moins un des flans extérieurs;
- projeter un jet d'eau sur ledit flan auquel la matière fibreuse est solidarisée, de manière à amener des fibres de cette matière à s'incruster dans les autres flans; et
- déplacer ledit jet d'eau le long de ladite ligne.
- les figures 1a à 5a et, respectivement, 1b à 5b, représentent les premières et dernières phases de cinq modes de mise en oeuvre de l'invention; et
- la figure 6 illustre un autre mode de mise en oeuvre.
