Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is for interposing a plurality of net fabrics into a laced knotless net in which lacing yarns are arranged substantially parallel to the knitting direction of the net fabrics. In particular, when removing the lacing yarn and separating the fabric, only the lacing yarn is cut, and the fabric can be easily separated without cutting the fabric.

<Prior art and its problems> In general, a wide net is required to manufacture large nets for fishing, nets spread over a wide space, such as nets for golf driving ranges, etc. .

Conventionally, in order to manufacture such mesh fabrics, the number of meshes was small,
A plurality of narrow net fabrics are prepared and these fabrics are connected by hand knitting, but this method is time consuming and extremely expensive. Therefore, recently it has been started to connect these at the same time using a knitting machine. The reason for connecting multiple net fabrics in this way is that a knitting machine capable of manufacturing a wide area of net fabric has not yet been developed (according to the knitting machines currently in use, the width is 200 stitches). ), not only because the area of one piece of net fabric is small, but also when knitting a wide area of net fabric,
If a broken net occurs in one place, there is an economical problem in that the entire wide area of the net must be replaced with another new one. This is based on the expectation that when the mesh fabrics are connected and each of the connected fabrics breaks, the fabric can be replaced with a new one. In order to connect multiple pieces of fabric in this way, lacing yarn is used, but the reason why the lacing yarn is provided is to prevent the width of the net from becoming wider and its strength to decrease. This is because reinforcement was also taken into consideration.

A conventional knotless net in which lacing yarns are disposed on the net fabric in this way is, for example, one or more lacing yarns arranged approximately parallel to the knitting direction at an arbitrary position on the net fabric, and In some cases, the lacing yarn was overlapped with the mesh yarn of the net fabric and knitted, and knots were formed at all intersections of the silk yarn and the lacing yarn forming the entire mesh. according to this,
If only a part of the mesh is broken, the lacing yarn has the inherent effect of preventing the spread of the broken mesh, but it is difficult to remove the broken mesh and replace it with a new one. It is necessary to separate the lacing thread from the mesh, but since all the intersections of the lacing thread with the mesh are knotted, the number of meshes to be cut is large, which is very time-consuming. Therefore, it is customary to pull out only the lacing yarn around the fabric and replace the entire wide fabric including the unbroken areas, but this is also very uneconomical. . In addition, even if you want to use one roll of net fabric by cutting it into a narrow net width from the beginning using the lacing threads provided at arbitrary positions on the net fabric, cutting the lacing threads is still very time-consuming. , which requires a considerable amount of time and effort, and is inconvenient.

There is also a method in which, for example, a lacing thread is passed through the mesh at the end of an adjacent mesh fabric, and then the lacing thread is sewn onto the mesh fabric using a sewing machine. , the cost is high, and when sewing with a sewing machine, the lacing thread is separated into the upper thread and the lower thread, and when sewing the meshes of adjacent net fabric alternately on the left and right with the lacing thread in between, the upper thread and the lower thread are separated. Since these lacing threads are simply intertwined with each other, there was a problem in that if these lacing threads were to break, the lacing threads would easily come off and the net fabric would be separated. Roughly speaking, it is also possible to prevent the lacing thread from coming off by passing the lacing thread through the mesh an appropriate number of times and then sewing the mesh threads that form the mesh at the ends of the fabric on both sides. However, there were also problems such as the strength of the silk thread becoming weaker.

Therefore, in order to solve the above problem, as shown in FIG. 3, in a knotless net in which a lacing yarn a is arranged approximately parallel to the knitting direction of the net, the lacing yarn a is In the end area of the adjacent mesh fabrics, c, pass through the meshes of both fabrics, c, and connect to the meshes of both fabrics, c, which are connected in the knitting direction. On the other hand, a mesh yarn d forming a mesh and a knitting knot e was also developed in a discontinuous depth in the knitting direction, but
According to this, the lacing yarn a and the mesh yarn d forming the mesh are
Since a knot elr is formed by this, 6. In order to separate both the net fabrics S and C, the lacing yarn a must be cut, but if only the lacing yarn a is cut, the net fabric will be cut.

A whisker-like residual thread will be left on the mesh thread d of C. The whisker-like remaining threads get in the way during lacing, so they need to be cut and removed. When cutting and removing them, the threads are often cut by mistake, resulting in damage to the threads themselves. It also means giving. Even if the net is broken, it is common practice to reuse the unbroken part depending on the degree of the break, so unnecessary loss i should not be caused.

Means for Solving the Problems〉 Therefore, the laced knotless net according to the present invention has the following features:
In order to solve the above problem, a plurality of lacing yarns are arranged approximately parallel to the knitting direction of the net, and this yarn group is divided into two,
Each thread group passes through the mesh of the mesh fabric and the other lacing yarn that has been bisected in the end region of the fabric fabric, and by forming a braid using only the bisected yarn groups and cutting only the lacing thread, both meshes are separated. This made it possible to separate the earth.

Embodiment Next, an embodiment of the laced knotless net according to the present invention will be described with reference to FIGS. 1 and 2. This is a knotless net formed by knitting the net fabrics 3 and 4 at the same time as the lacing yarn 2 arranged substantially parallel to the knitting direction of the net. In this case, two or more lacing threads 2 are used, one of which, the lacing thread 2a, passes through the mesh at the end of one of the mesh fabrics 3, and the other lacing thread 2b passes through the mesh at the end of the other fabric 4. Pass through, and both lacing threads 2a and 2b
They are also constructed so that they fit through each other. Each of the net fabrics 3.4 is knitted in the same way as a normal knotless net by forming knots at each intersection using a large number of silk threads. During knitting of these fabrics 3, 4, the lacing yarns 2a, 2b are applied to both fabrics 3.4 in the end regions where the respective fabric yarns of each fabric 3.4 are folded back.
The lacing yarns 2a and 2b pass through the mesh at the ends of the lacing yarns 2a and 2b to form knots 5 in some parts. This knot 5 is created when a part of the lacing threads 2a, 2b is accidentally cut.
This is to prevent b from unraveling over a long distance, and for that purpose, the knots 5 may be formed at one point each at appropriate intervals, or may be formed at several points in succession. There is no particular limitation on the structure of the lacing yarn 2a, and it may be one that has been generally used for knotless nets in the past. In this case, the lacing yarn 2b passing through the mesh fabric 4 may transfer to the other fabric 3. Alternatively, it may return to its original side after forming the knot 5. In addition, in the illustrated embodiment, only one lacing thread 2 is shown on each side, or a plurality of lacing threads 2 may be used.

In addition, in the embodiment described above, the lacing yarns 2a, 2b
The threads were passed through only the early stitch rows of the mesh at the adjacent ends of each of the mesh fabrics 3 and 4, but for example, it could be made to pass through the silk threads in one or more stitch rows from the end. In general, the number of lacing threads 2 may be increased compared to the embodiments described above.

What is shown in FIGS. 1 and 2 differs only in the direction of the peaks and valleys at the ends of both net fabrics 3.4, and there is no other difference.

However, if one of the mesh fabrics 3 and 4 is broken and you want to remove only the broken fabric, that is, if the mesh fabric 3
, 4, by simply cutting only the part of the lacing yarns 2a, 2b that are knotted 5, the net fabric 3 can be separated.
, 4 can be separated, and the lacing threads 2a, 2b can be easily pulled out. This is lacing thread 2a
, 2b is not tied 5 to the net fabrics 3 and 4. Therefore, the work of cutting and pulling out the lacing threads 2a, 2b becomes easy, and the work time is shortened, work efficiency is improved, and labor is saved. In addition, the knotless mesh can be easily cut and removed as a partial mesh.
The net fabric can be used effectively, and economic efficiency is also improved.

Incidentally, the knotless net is not limited to that of the above embodiment, and may be modified in various ways depending on the purpose of use, conditions, etc.

<Effects of the Invention> As described above, according to the laced knotless net according to the present invention, a plurality of lacing yarns are arranged approximately parallel to the knitting direction of the net, and this yarn group is divided into two. The yarn group passes through the mesh of the net fabric and other lacing yarns that are bisected in the edge area of the net fabric, and only the bisected yarn groups form a knot. By forming knots with only the lacing yarn without using the lacing yarn, and cutting only the knotted part of the lacing yarn, each fabric can be separated immediately and easily without causing unnecessary damage to the fabric. This has the effect that it can be done.
