Description

[Detailed description of the invention] This invention relates to a rope slit forming device, and more specifically, the rope is formed by loosening a portion of the strands of the rope while loosening a portion of the rope strands. This invention relates to a rope forming device for winding ropes along the twisting direction.

When making a ring at the end of a rope by inserting it into a loop, you can loop the end of the rope and secure it with a sleeve or fastener, or you can make a ring by looping the end of the rope and securing it with a sleeve or fastener. A base-to-base splicing method involves sequentially inserting a part of the strand into a loosened part, winding the separated strands along the twisting direction of the rope, and then inserting and fixing the strands in the same way. be.

In the former case, the work is easy, but in the case of fishing equipment that is submerged in seawater, the metal fasteners corrode and may come off unexpectedly, which is dangerous, and in the latter case, the work is easy because the metal fasteners are corroded and may come off unexpectedly. In order to loosen the strand, insert the strand with the loose end into the loose part and wrap it around the waist.There was no efficient work tool available, so I used multiple sharpened iron rods (spikes) and a pipe spike to loosen the strand. The procedure is to loosen a part of the strand and insert the strand with the end separated during this time, and it takes 2 to 3 people to do it.
It was not a good method as the strands were easily damaged as the spikes were driven in with a hammer over and over again.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a stand made of plywood, etc., and a pair of self-returning beaks attached to the top of the stand. A fluid pressure piston that opens these beaks against the return force, a fluid pressure mechanism that operates this piston, and a spiky that locks the rope to be processed and is inserted into the beak attachment part. and a spiky inserter that presses the strands to form a gap between the strands.
