る。<Prior art and its problems> Gill net fishing is a method in which each member of a school of visiting fish plunges into the mesh of a net suspended vertically in the water, entangling its gills with the threads of the net. This is a method of catching fish using In gillnets used in this fishing method, if the strength of the nodules' slippage is low, fish that penetrate the net will be attacked, causing slippage before the net line breaks and failing to catch the fish. As a result, it becomes impossible to maintain the correct diamond pattern, and the coverage rate of the fishing net decreases.At the same time, the tension applied to the net legs becomes uneven, leading to an increase in broken nets, and the performance of the fishing net is significantly reduced.

欠点があつた。 Traditionally, nylon monofilament has been widely used for the gillnets mentioned above due to its transparency and strength and elongation properties, but the fiber itself has relatively high rigidity and the surface of the fiber is smooth. Various methods have been proposed for making knots to prevent the misalignment that tends to occur due to the presence of knots. This has resulted in disadvantages such as deformation of the cross section of the fibers, which reduces the hooking strength due to unreasonable force being applied to the net threads, and also makes it difficult to open the net legs in all directions.

択したのであつては完成し得ない。 However, as a method for forming a nodule having a relatively strong structure, there is a method disclosed in, for example, Japanese Patent Application Laid-open No. 81273/1983. However, according to this method, the warp threads are wound once around the upper hook, then removed, and then wrapped once more. Generally, in order to wind or unwind the warp threads around the upper hook, it is necessary to use a thread swinger, but in order to wind the warp threads twice around the upper hook as described above, the method disclosed in the above publication does not allow Since it includes a process of removing the product, it becomes intermittent.
Therefore, even though it ends up being wrapped twice, it inevitably takes a long time to complete the entire process. In addition, in the same publication, there are actually many movements in which the warp threads once hung on the upper hook are removed from the upper hook, and the warp threads are re-hanged from the side opposite to the side from which it was removed. The reality is that it is not possible to hang accurately on all of the upper hooks. Generally, as a matter of course, the warp threads are connected to a large number of upper hooks as mentioned above.
Must be multiplied by 100%. However, due to some circumstances, the tension of the warp yarns may become uneven, and such nets themselves result in a decrease in quality, so defective areas must be repaired.
In order to eliminate this complication, the knitting net worker must concentrate on preventing the warp threads from failing to hook onto the upper hooks, and the equipment required to adjust the warp thread tensions must also be extremely sophisticated. Especially in this case, when the warp threads are hung for the second time, the tension on the warp threads is loosened because the warp threads that were hung for the first time have been removed, making the above problem even more serious. be. Furthermore, the method of hanging the warp threads on the upper hook requires not only vertical movement of the thread swinger, but also horizontal movement. Of course, if the thread swinger were simply moved up and down, the warp threads would collide with the upper hook, so in order to avoid this, the cited example revolves around the upper hook, resulting in a two-dimensional movement of up and down, left and right. Because of the forced movement, the shape of the cam for performing this movement is complicated, and the shape of the sliding surface of the cam is also complicated, so precision in the swinging movement is strongly required. As shown in the above publication, when the process of removing the warp that has been hung once on the upper hook and hanging it again, the warp on the swinging side becomes one warp on the knotting side and two wefts, totaling 3. In order to wrap the book 3/2 of the way around the book, the second time the warp threads are hooked onto the upper hook, they will not be wrapped yet, so they should be wrapped around the upper hook 1/2 of the way and finished with the warp threads facing the side of the book. I have no choice but to do so. With the upper hook facing the bunsen side, the front hook passes through both the warp and weft loops formed on the upper hook, pulls out the warp, passes through the weft, and then removes the upper hook from both the warp and weft loops. The operation and the subsequent tightening operation are extremely unsmooth, and the disadvantage is that the tightening is incomplete. In other words, both the warp and weft loops formed on the upper hook are always pulled toward the swinging side by the warp on the swinging side, so in order to remove both the warp and weft loops from the upper hook, pull the upper hook toward the swinging side. Therefore, it must be tilted extra. Moreover, since the knotting point is pulled by the warp threads on the swinging side and moves extra toward the swinging side, an extra stroke is required for tightening the stitches, resulting in poor stitching. ,
This results in defects such as decreased productivity. Generally, in this type of knotting method, a conventionally known device is used to form the knots, and various knots are formed by a combination of the rotation of the upper hook and the vertical movement of the thread swinger. However, in the case of the special knot that is to be obtained with this invention, at least it does not exist in the past, and the rotation speed of the conventional upper hook,
Otherwise, it cannot be completed if the direction, timing, etc. are simply selected.

ある。<Means for Solving the Problems> Therefore, in order to solve the above-mentioned drawbacks, the knotting method of the net according to the present invention suppresses the extreme increase in the amount of net yarn required for forming knots, and the knotting method of warp yarns and weft yarns. There is no mutual twist between the loops, the warp loops and weft loops are parallel, and there is no entanglement between the warp and weft threads between the loops, allowing for smooth and uniform tightening, as well as warp threads on the knotted side that have already been knotted. By winding both the warp and weft 1.5 turns with the warp to form a condition in which both the warp and weft on the knot side are aligned, it is possible to achieve more uniform and strong tightening, and it also improves the exchange strength and makes it possible to tighten the mesh in all directions. It is an object of the present invention to provide a highly productive manufacturing method for obtaining a tuberosity that allows for good leg opening.

鳥の効果を有するのである。<Effects of the Invention> As described above, in the method for knotting a net according to the present invention, warp loops and weft loops are formed by the rotation of the upper hook 1, the vertical movement of the thread swinger 3, and the vertical movement of the lifting plate 5. This allows for smooth movement and contributes to higher speed knitting machines. According to the above publication, the warp threads are wound once around the upper hook (referred to as the maki hook in the above publication), and then this is removed.
There is one more winding process, but at this point, the number of windings for the warp on the swinging side is zero for a total of three threads, one warp and two wefts on the knotting side, so there are 3 windings. In order to obtain two turns of winding, the upper hook must be rotated two-thirds of the way so that the upper hook faces the dividing direction, which causes the above-mentioned drawback. In the present invention, the warp is wound twice in succession,
Since the process of removing the warp threads is done once in the later process, in order to wrap the warp threads around the upper hook twice, this process must be performed continuously in this invention. That being said, it will take much less time to complete the entire process. Also, by winding it twice in succession in this way, it is possible to accurately hook all of the large number of upper hooks. Furthermore, in the method of hanging the warp threads on the upper hook,
In this invention, since it is a one-dimensional movement of only vertical movement, the cam sliding surface is small and the movement is simple. Therefore, the shape of the cam for performing this movement is simplified, and it is also effective in terms of maintenance of the device. Not only is this excellent, but it also has various effects such as shortening the time required for the swinging motion. The greatest effect of this invention is that the operation of winding the warp threads around the upper hook twice in succession and then removing them once in the subsequent process creates a state in which the upper hook is directly facing the thread swinger at the end of this operation. The warp on the swinging side also serves as an operation in which a total of three threads, one warp and two wefts on the knotting side, are wound one-half turn (see Figure 1, 15). By adopting such a clever method,
Thereafter, the upper hook faces directly in front of the thread swinger, that is, the upper hook faces in a direction that makes it easier to remove both the warp and weft loops formed on the upper hook from the upper hook, which has the effect of killing two birds with one stone.

締めつけて目締めする工程。[Scope of Claims] 1. A method for knotting a mesh, characterized by comprising the following steps 1 to 9. 1st step: The step of turning the rotatable upper hook facing the thread swinging side a quarter turn. 2nd step: After raising the thread swinger, turn the upper hook half a turn in the opposite direction, then lower the thread swinger to hang the warp threads on the upper hook. 3rd step: Move the upper hook 1/2 in the same direction as the 2nd step
After rotation, the thread swinger is raised, then the upper hook is rotated a further half turn in the same direction, and then the thread swinger is lowered to wind the warp threads around the upper hook. 4th step: move the upper hook 1/2 in the same direction as the 2nd step
The process of raising the lifting board after rotation. 5th step: With the lifting plate raised, attach the upper hook to the first position.
The process of making a half turn in the same direction as the process, hooking the weft to the upper hook from the opposite side to the warp, lowering the lifting plate, lowering the weft to the upper hook, and raising the thread swinger. 6th step: Move the upper hook 1/2 in the same direction as the 1st step
The process of rotating and passing the weft thread under the warp on the swing side to remove the warp on the swing side from the upper hook, and then lowering the swing. 7th step: Move the upper hook 5/4 in the same direction as the 2nd step
The process of rotating. 8th step: A step in which the warp threads are pulled out using the front hook from the warp and weft loop formed on the upper hook, and the weft threads are passed through. 9th process: The process of removing the upper hook from the loop and tightening the warp and weft threads.
