Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for tying a branch thread for repair to the original thread at a torn place in a torn fishing net or the like when repairing a torn fishing net or the like. The present invention relates to a device for tying a branch yarn to a main yarn.

[Problems to be solved by conventional techniques and inventions] Generally,
To repair a torn fishing net, etc., tie one end of the repair branch to one of the threads at the torn point of the net, and tie the other end of the repair branch to the other thread at the torn location. Conventionally, the repair branch threads are tied to the original thread in the net by using a shuttle around which the repair branch threads have been wrapped in advance, as is well known. I try to do it manually.

However, tying the repair branch yarn to the main thread in the net requires a high level of skill, as a special knotting method must be used to prevent the repair branch thread from shifting in the longitudinal direction of the main thread. It was extremely inefficient.

In the present invention, when repairing a torn net, when tying a branch yarn for repair to the original yarn at the torn part of the net,
The present invention proposes a device that can mechanically tie branch yarns to the original yarn without shifting in the longitudinal direction of the original yarn.

[Means to solve the problem]

In order to achieve this goal, the present invention has a guide part that reciprocates a chatotre with a built-in bobbin wound with branch threads, a main thread holder part that inserts the main thread to tie the branch threads, and a front three-way main thread. and a loop-forming body that moves forward toward the guiding part and then retreats while rotating with the original thread in the system insertion part being locked at two points, and the chatotre is formed by the loop-forming body. It is configured to pass through the loop of the original yarn, move forward to a position beyond the original yarn insertion portion, and then move backward to the original position.

[For production]

In this configuration, as the loop-shaped body moves forward while rotating, a loop portion of the main thread is formed in the middle of the main thread inserted into the main thread insertion section.

Next, when the chasol moves forward and passes through the loop of the original yarn, and the branch yarn is inserted into the loop of the original yarn, one end of both ends of the original yarn loop is inserted. Then, the shuttle is wound around the intersection of both ends so that the other end is aligned with the other end, and then the shuttle is moved back to the original position passing through the original yarn loop.

Then, the branch yarn let out from the chatotre passes through the original yarn loop, is folded back in a U-shape around one end of the original yarn loop, and then passes through the original yarn loop again. Since the branch yarns are folded back in a U-shape and intertwined with the loops, the branch yarns can be tied to the original yarn without shifting in the longitudinal direction of the original yarn.

〔Effect of the invention〕

Therefore, according to the present invention, when repairing a torn net, when tying a branch yarn for repair to the original yarn at a torn location in the net, the branch yarn is misaligned in the longitudinal direction of the original yarn with respect to the original yarn. Since it is possible to tie the wires together without having to do it manually as in the conventional method, work such as repairing the net can be done extremely easily and quickly without requiring any skill. have an effect.
