Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for repairing a torn fishing net or the like by tying a branch thread for repair to the main thread at a torn part of the net. This invention relates to a device for tying a branch yarn to the middle of a main yarn.

[Problems to be solved by conventional techniques and inventions] Generally,
To repair a torn fishing net, tie one end of the repair branch yarn to the middle of one of the main threads at the torn point of the fishing net, and tie the other end of the repair branch thread to the other main thread at the torn point. This is done by tying it to the middle of the , but conventionally,
As is well known, the tying of the repair branch line to the original line in a fishing net is carried out manually using a chatsol around which the repair branch line has been wound in advance.

However, tying the repair branch line in the middle of the main line in a fishing net requires a special knotting method that prevents the repair branch line from shifting in the longitudinal direction of the main line. It required skill and was extremely inefficient.

When repairing a torn net, the present invention is capable of attaching a branch yarn to the middle of the original yarn, such as when tying a branch yarn for repair to the original yarn at a torn part of the net. To provide a device that can mechanically connect devices reliably without shifting in the longitudinal direction.

[Means to solve the problem]

In order to achieve this object, the present invention includes: a pair of left and right locking bodies that lock the source yarn; a pair of left and right hook bars that open away from each other after passing between the two locking bodies; It consists of a hook rod that moves forward between the two hook rods and a hollow needle rod through which a branch thread for tying the original thread is inserted, and the hook rod moves backward from between the two locking bodies. When the hook lever and the hollow needle rod are opened, the hook rod and the hollow needle rod are configured to enter between the two, and the branch yarn drawn out from the tip of the hollow needle rod,
A configuration is provided in which a transition means is provided so that the hollow needle rod and the hook rod are hooked on and transferred to the hook rod in the advanced state.

[For production]

In this configuration, when the middle of the main thread is locked in both the locking bodies, both hook bars hook the main thread between the two locking bodies, move backward, and then open to separate from each other. A loop portion is formed in the middle. Next, by entering the hook rod and the hollow needle rod into this loop part,
A branch thread, which has been previously inserted into the hollow needle rod, is passed through the loop portion in a folded state.

Then, when the transition means detours the branch yarn passed through the loop portion in a bifold state so as to wrap around the proximal end of the loop portion, and then hooks it onto the hook rod and moves on its own, the hook rod and the hollow needle rod are By retreating so as to come out of the loop part, the branch thread hooked on the hook rod is passed through the loop part again, so the branch thread is shifted in the longitudinal direction of the main thread with respect to the middle of the main thread. It is possible to connect them reliably without any problems.

〔Effect of the invention〕

Therefore, according to the present invention, when tying a branch yarn to the middle of the original yarn, the branch yarn is prevented from shifting in the longitudinal direction of the original yarn! Since the f3+ mouth can be tied mechanically without manual work as in the conventional method, work such as repairing the net can be done extremely easily and quickly without requiring any skill. has.
