Description

【発明の詳細な説明】この発明は漁網の結節構造に関し、特に二重結節構造の
結節工程において、最初に形成されるタテ糸のループと
ヨコ糸のループとをからませるように構成した変形蛙又
結節構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knotted structure for fishing nets, and in particular to a modified frog constructed to entangle warp thread loops and weft thread loops that are first formed in the knotting process of a double knotted structure. It also relates to the nodal structure.

従来、モノフィラメント製の漁網では、モノフィラメン
トの表面が平滑で滑り易く、結節が弛み易いことから、
二重結節構造とし、その構造にも弛みを防止するため種
々の構成のものが提案されているが、これ等の結節構造
においては結節工程の最初の段階で形成されるタテ糸の
ループとヨコ糸のループは単に重ねられるのみで、これ
等のループ相互がからみ合った構成のものではなく、大
きな力で目じめしても、そのめじめ保持力が弱く、目ず
れ、目がえり等が生じ易かった。Conventionally, monofilament fishing nets have a smooth and slippery surface, and the knots tend to loosen.
Various configurations have been proposed to prevent loosening of the double-knotted structure, but in these knotted structures, the loops of the warp yarn and the weft yarn formed in the initial stage of the knotting process are The thread loops are simply overlapped, and these loops are not intertwined with each other, so even if it is moistened with a large force, its retention force is weak, causing misalignment, burrs, etc. It was easy to occur.

そのため漁網使用時、その目ずれ、目がえりがなく安定
した漁網とする目的で、結節部にヒートセット加工、樹
脂含浸加工または、これらの併合加工等の後処理を施こ
している。Therefore, when using a fishing net, the knots are subjected to post-processing such as heat-setting, resin impregnation, or a combination of these processes in order to make the fishing net stable without misalignment or burrs.

しかしながら、これ等の後処理のために漁網製造の生産
性は低下し、製造原価が高くなる等の欠点がある。However, such post-processing reduces the productivity of fishing net manufacturing and increases manufacturing costs.

提供するものである。In view of the above, the present invention is constructed so that warp thread loops and weft thread loops formed at the initial stage of the tying process are intertwined with each other, thereby eliminating misalignment and curvature of the eyes without the need for post-processing. The present invention provides a knotted structure that has a firm clenching holding force that does not cause sagging.

るものである。The gist of this invention is to connect the root of the weft loop and the warp entry portion below the warp loop to the lower part of the warp thread so as to entangle the warp thread loop and the weft thread loop formed in the first stage of the knotting process. The loop wraps around the base of the warp thread loop and the lower weft thread entry part of the weft thread loop. It is characterized by being configured so that it passes through and wraps around.
