Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for forming reinforcing mesh rows in a knotless mesh fabric.

[Conventional technology]

Fishing nets, nets for golf practice ranges, etc. often require wide net fabrics, and in such cases, the nets are constructed with thick threads called power threads or double threads at appropriate intervals. Reinforcing mesh rows are required for strength as well as for convenience in tailoring.

In Kajimata knotted netting, the warp threads of the knitting machine flow in a staggered manner between the left and right weft threads to form knots while manufacturing the net fabric, so the net fabric can be fabricated with tension threads arranged vertically at arbitrary positions. However, in the case of a penetrating knotless mesh fabric, a mesh fabric in which force threads are placed outside the edges of the mesh fabric is known from the specification of Patent No. 148179.
In this case, the thick threads that serve as force threads are arranged in a diagonal manner on the mesh fabric, and in the staggered knotless fabric, the force threads are inserted along the mesh rows as disclosed in Publication of Utility Model No. 12-1562. It is well known that each of the net yarns that make up the net fabric is continuously folded back in a zigzag pattern for each net leg, and this is because the thick yarns that serve as force yarns are thicker than the other net yarns. It is a yarn, and the number of twists must be smaller than other mesh yarns, and it is necessary to form an effective reinforcing mesh row for the penetration type knotless mesh that is generally put into practical use. Netting is not known, and when a wide netting is required with a through-type knotless netting, the netting and netting are done while inserting force threads.
It has to be used edge to edge, requiring many means.

In addition, in the matters described in the above-mentioned specification of Patent No. 148179 and Japanese Utility Model Publication No. 12-1562, a thick strand is used as the power thread, so the winding length around the weight is short, and the weight of this part is short. Machines have to stop frequently for thread changes,
The net-making efficiency is reduced, and the technology of Patent No. 148179 uses plied yarn strands for the portions of the net yarn that are not reinforced, so most of the net fabric uses expensive strands that require a lot of twisting processes. In addition, in the technology of Utility Model Publication No. 12-1562, the number of twists of the thick power yarn must be smaller than that of other net yarns, which reduces the rotation of the spindle of the net making machine. The gear ring had to be replaced every time, and this work was required every time the thickness of the thread of the net fabric changed, which was a pain, and the fact is that it has not been put into practical use until now, more than 40 years after its invention. be.

[Purpose of the invention]

The present invention was made in view of these circumstances, and solves the conventional problems with a simple configuration.
Fold back the reinforcing yarn, which is the same yarn as the net fabric constituent yarn, in a zigzag pattern every three net legs at the required location so that the net yarns of all the net legs are composed of two identical yarns over the width of one stitch and a half. Moreover, it is an object of the present invention to rationally and inexpensively manufacture and provide a knotless net in which a reinforcing mesh row is provided by being arranged in parallel with the net fabric constituent threads and braided simultaneously with the net fabric body at the knitting portions. be.

[Structure of the invention]

The configuration of the present invention that solves the problems of the prior art is as follows:
When manufacturing a penetrating knotless mesh fabric, reinforcing yarns that are the same as the threads that make up the fabric are added to the required areas over one stitch and a half width so that every mesh leg is composed of two mesh threads. It is characterized in that it is folded back in a zigzag pattern for every three net legs, and is arranged in parallel with the net fabric constituent threads, and is braided at the knitting section at the same time as the net fabric main body.

〔Example〕

To explain the embodiment of the present invention with reference to the drawings, the net fabric constituent yarn 1 flowing from the upper right to the lower left is two strands twisted together, and the net fabric constituent yarn 2 flowing from the upper left to the lower right is similarly two strands. This is due to the twisting of strands. At each intersection of the net fabric constituent yarns 1 and 2, each strand is combined vertically to form a penetrating knotless net fabric A.

Reference numeral B denotes a reinforcing mesh row of one stitch and a half width formed at a predetermined portion of the above-mentioned knotless mesh fabric A, and the reinforcing mesh row B is made of other reinforcing threads 3, 3,
4 and 5 are sequentially folded back in a zigzag manner at the knots on both sides of the reinforcing mesh row every three mesh legs as shown in the figure, and at the other joints 7 of the reinforcing mesh row B,
All the mesh legs of the reinforcing mesh row B are formed of two common threads.

The knotted parts 6 on both sides of the reinforcing mesh row B are formed by the composition method of the combined knotted parts of six lower twisted yarns described in Japanese Patent Publication No. 36-8134, and the other knotted parts 7 of the reinforcing mesh row B is composed by the composition method of a combination of eight loosely twisted yarns as described in Japanese Patent Publication No. 53-28546.

〔effect〕

In this way, the present invention is not just an invention of a net leg intersection, but also a method for rationally forming and arranging reinforcing mesh rows in a penetrating knotless net fabric commonly used by fishermen. A knotless mesh can be provided. Furthermore, when using the method of forming a reinforcing mesh row of a knotless mesh according to the present invention, there is no need to manually insert power threads, or a mesh containing reinforcing threads as disclosed in Patent No. 148179 and Japanese Utility Model Publication No. 12-1562. There is no need to reduce the net-making efficiency due to yarn changes or to use expensive plied yarn for most of the net fabric, and the net yarn thickness is the same as that of the regular net fabric part A. Since the reinforcing mesh row B is formed using the same yarns with the same number of twists, the same strands can be used for making the net, making it possible to change the yarns all at once, and making it possible to provide wide nets at low cost for mass production and industrial purposes. The practical effects are significant.

The introduction of this technology has had extremely important industrial effects, such as making it possible to produce knotless nets with only 200 nets, whereas previously there were only 100 knots.

The reason why the width of the reinforcing mesh row was made one stitch and a half width is as follows.
The range in which force threads are inserted for reinforcing this type of net fabric is:
This is because a reinforcing mesh row of about one and a half mesh width is sufficient, and no more reinforcing mesh rows are required.
