Description

NCEUD ENABLING THE CONNECTION BETWEEN TWO LINES EXTENDING CABLE TO CABLE

  The present invention relates to a node capable of ensuring the connection between two lines extending side by side, more particularly adapted to ensure the connection between a support end supporting at least one net and a waterline or ballast, as well as the net thus obtained.

  In the case of a fishing net, the one or more layers are connected at their upper meshes to a first mounting wire and at their lower meshes to a second mounting wire. Subsequently, the first mounting wire is connected to a water line and the second mounting wire to a ballast line. Such an assembly requires a large number of hours of manpower. To reduce production costs, manufacturers are increasingly seeking to relocate most of this assembly to low-cost areas. However, the installation on the water lines and the ballast lines can only be done near the home ports of the boats. Indeed, the transport of a net equipped with water lines and ballast (with possibly a transport to the lines to be equipped) is relatively expensive and has a cost higher than that of assembly, contrary to the nets of nets which are light and can be transported from one continent to another with relatively low transport costs. Thus, the plies of nets are pre-assembled in countries with low labor costs. This pre-assembled assembly is then connected to the waterline and ballast using the mounting wires.

  There are many techniques to ensure the connection between the one or more layers and mounting son. For example, the mounting wire may pass through half-meshes reported to the upper edge and / or lower of the or layers. However, other techniques could be considered.

  The mounting wires must be connected to the waterline or ballast in a solid manner, while ensuring a homogeneous distribution of the mesh of the layers along the waterline or ballast. According to a first technique, the mounting wire is stitched at regular intervals on the waterline or ballast by isolating between the stitching points a predetermined number of stitches. Even if this technique makes it possible to keep, during use, the sheets homogeneously distributed over the entire length of the water lines and ballast, it does not give full satisfaction because the mounting on the water lines and / or ballast is relatively long and therefore expensive. In addition, the separation of the waterlines during the change of water tables is relatively long and expensive. According to another technique, the waterline or ballast is threaded into loops formed at the level of the mounting wire. For faster assembly, the loops can be threaded onto a conduit in which the water line or ballast can pass. By pulling on the waterline and the mounting wire, the loops are transferred from the conduit to the waterline or ballast. Although this technique allows assembly and rapid assembly, it is not satisfactory because the meshes may not be evenly distributed, loops being able to slide along the waterline or ballast.

  According to a last technique, instead of each loop, one can realize a node in the form of inverted half-keys. As before, these nodes can slide which can affect the distribution of meshes along the waterline or ballast.

  Also, the present invention aims to overcome the drawbacks of the prior art by proposing a nceud to ensure the connection between a mounting wire and a waterline or ballast and more generally between two lines extending side by side .

  To this end, the invention relates to a nceud capable of providing a connection between two lines, ropes or the like, including a waterline or ballast and a mounting wire which is connected at least one net ply, characterized in that it consists in: forming, at a line, a first loop comprising two strands connected at the level of the top of said first loop and deviating at the level of the foot of the first loop, bending downwards the upper part of the first loop and arranging the lower portions of the strands between the upper portions of the strands connected to the top so as to form a second loop, - forming a third loop with the lower parts of the strands under the second loop, - introducing the third loop in the second loop, - move the end of the third loop and the lower parts of the strands, so as to form said nceud. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings in which: FIG. 1 is a schematic representation illustrating two lines connected punctually by nodes according to the invention, - Figures 2 to 5 schematically illustrate the different steps for the realization of a nceud according to the invention, - Figure 6 is a perspective view illustrating a node according to the invention made on a first line forming a sliding loop through which another line passes. FIG. 1 shows a first line 10, a second line 12, said lines 10 and 12 being connected punctually by nodes 14. By line, we mean all types of ropes, in particular lines, ends, yarns, strands, ropes or other that may be stranded, braided, intertwined, crisscrossed, milled or otherwise. Lines 10 and 12 can be made from different materials. According to the variants, the lines 10 or 12 may have different diameters. According to an application example more particularly adapted, the first line 10 could be a waterline or ballast and the second line 12 a mounting wire which would be connected at least one net ply so as to constitute a fishing net.

  The node 14 is of sliding type and it comprises a loop 16 formed from a line, according to the example the second line 12, whose opening dimensions are likely to vary so as to grip the other line, according to the example the first line 10. According to the invention, the nceud 14 is made in the following manner As illustrated in Figure 2, from one of the lines, is formed a loop 18 comprising two strands 20, 20 'connected at the top 22 of the loop 18 and deviating at the foot of the loop 18. As shown in Figure 3, the upper part of the loop 18 is bent downwards and the lower parts 24, 24 'of the strands are placed between the upper portions 26, 26 'of the strands connected to the top 22 so as to form a loop 28. As illustrated in Figure 4, a loop 30 is formed with the lower portions 24, 24' of the strands under the loop 28.

  This loop 30 is introduced into the loop 28, as shown in Figure 5. By removing the end 32 of the loop 30 and the lower portions 24, 24 'of the strands, we obtain a nceud as shown in Figure 6 Preferably, a plurality of nodes 14 each with a loop 30 are made at the second line 12, the nodes 14 being separated by a predetermined distance and isolating a predetermined number of meshes from the one or more layers of net. The set of loops 30 are threaded and distributed homogeneously on the first line 10, then the knots are tightened so as to stop and no longer slide on said first line 10. According to another characteristic of the invention the length of the second line between two consecutive nodes 14 is greater than that of the first line between the same two nodes 14. According to a mounting technique, the loops 30 of the nodes 14 can be threaded onto a rigid or flexible tube, then transferred to a line, when that line is threaded into the tube. However, other technical solutions can be envisaged. According to the invention, this node allows rapid assembly and disassembly due to the presence of a sliding loop.

However, thanks to its design, when it is tightened, this node stops at the line on which it is threaded, which makes it possible to maintain a homogeneous distribution of the nodes 14 along said line. Of course, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all variants, particularly with regard to the nature, the dimensions of the lines and the application .
