Description

[Detailed Description of the Invention] This invention relates to nets such as fishing nets, and particularly relates to the structure of a multilayer net having extremely high strength.

Conventionally, in order to increase the strength of the net, it has often been done to change the material of the net yarn, increase the diameter of the yarn, or improve the way the net is knitted. However, there is a limit to how much the strength of the net can be increased by such improvements, and it has not been possible to dramatically increase the strength of the net.

This idea proposes that the strength of the net can be dramatically improved by overlapping multiple layers of netting. At the same time, considering that even a highly strong net would be meaningless if it were to spread if it were to break, we also worked to ensure the integrity of the layers and to ensure that no run-through occurs even when the net breaks. The aim is to provide a new network structure based on

That is, the net according to this invention is a net in which a plurality of layers of net portions are stacked one on top of the other in the vertical direction, and a braided part is formed in the netting portion of each of the net portions, so that the net portions are integrally overlapped. It is characterized by the presence of

Hereinafter, a detailed explanation will be given according to the attached drawings. FIG. 1 is a partial perspective view showing an embodiment of the net according to this invention, and FIG. 2 is a schematic diagram illustrating the overlapping state of the net portion. It is.

The illustrated net 10 includes an upper net portion 20 and a lower net portion 3.
0, the braided cord part 40 is formed in the net legs 21 and 31 of each of the net parts, and the upper net part 20 and the lower net part 30 are integrally polymerized. It is.

The net portions in this invention, that is, the main body portions of the upper net portion 20 and the lower net portion 30, can have the same configuration as independent nets. Illustrated upper mesh part 2
0 and the lower net portion 30 are constructed of knotless net portions in which the intersecting portions of the twisted yarns, that is, the knotted portions 22 and 32 are not knotted.

The braided part 40 can be braided using a conventionally known braiding method such as a so-called four-strand or six-strand braid.

In all of the examples, a net consisting of two layers of upper and lower layers is shown, but nets with three or more layers can also be integrally polymerized by forming a braided part in the legs of the net in the same manner as above. .

In the multi-layered net of this invention having the above configuration, the net has a plurality of layers stacked on top of each other in the vertical direction, and a braided part is formed in the net leg of each of the nets, so that each net Since the parts are integrally polymerized, the net has the same strength as the overlapped net parts, so-called 2-ply, 3-ply
It was possible to obtain a net with extremely high strength, which is the same as in the conventional method of using a layered net.

In particular, in this invention, since a braided part is formed in the net leg part of each of the net parts and each of the net parts are integrally superposed, a reinforcing part made of the braided part is formed in the relatively easily damaged part of the net leg part. At the same time, even if the threads constituting the net legs are cut, the so-called run-through phenomenon in which the net legs are untwisted by the braided portions can be prevented.

Furthermore, since this invention forms and integrates the braided part at the net leg, it has the great advantage of being extremely easy to manufacture compared to the case where it is integrated at other parts, such as the knitted part. It is something to be prepared for.
