Description

[Detailed explanation of the idea] The present invention relates to improvement of net thread used in fishing nets and the like.

In order to increase the specific gravity of fishing nets, ropes, etc., lead wires are embedded or twisted together, but when lead wires with a circular cross section are used, even if the surrounding area is covered with fiber strips, the lead wires are It cannot cope with the elasticity of the net threads, so it protrudes from the rope or the net yarns, and especially when the net yarns are mixed and twisted, the twists are not included, and the knots or knotted parts cannot be securely fixed.

In order to prevent this defect, after forming lead into a tape shape and covering its surroundings with synthetic resin, a core rope with fiber threads attached around it was embedded or burned in other fiber threads. −
Although it is considered in Publication No. 30446, not only is it not possible to effectively increase the specific gravity of the net yarn by simply mixed twisting, but also the twist balance is poor when mixed and twisted with other fibers as a net yarn, and it still ensures that the lead tape will come out. Is it not possible to prevent this?It is the current situation.

The present invention is an attempt to improve these defects, and consists of a plurality of threads bonded with adhesive so as to cover the entire circumference of an ultra-thin tape made of lead or lead alloy with synthetic fibers along its longitudinal direction. The gist is that the book is first twisted and then twisted in the opposite direction.

An embodiment of the present invention will be described with reference to the drawings. Synthetic fiber strips 2 are adhered to the entire circumferential surface of a narrow, ultra-thin tape 1 made of lead or lead alloy so as to be densely coated with adhesive in the longitudinal direction. A thread 3 is formed, a plurality of threads 3 are first twisted, and then twisted in the opposite direction to form a mesh thread 4.

Therefore, it is preferable to use polypropylene, polyethylene, polyester, etc. as the synthetic fiber thread 2, and to use a split yarn of these materials, and for the thread 3, two to three threads are first twisted and then twisted in the opposite direction. It is best to twist them together.

In this invention, the entire surface of an ultra-thin tape made of lead or lead alloy is bonded with an adhesive so as to cover the synthetic fiber strip along its longitudinal direction, and after that, multiple threads are twisted in the opposite direction. , each yarn forming the net yarn is of the same quality and twisted in a well-balanced manner while maintaining sufficient elasticity, and the lead or lead alloy tape of each yarn is also twisted. It can reliably prevent the lead alloy tape from flying out, maintain sufficient strength and elasticity as a net yarn, and efficiently form a large specific gravity of the net yarn, and can also be used to form knots or knots when made into a net. It can also be securely fixed, and has excellent features and practicality that are not found in conventional net yarns, such as fixed nets and other high-density net yarns.
