JPH0892850A - Production of square-hole net - Google Patents

Abstract

PURPOSE: To provide a method for producing a new square-hole net not causing the untwisting of the net leg from a cut part of the net and thereby capable of being used as the square-hole net in the cut state as such without fixing the cut fibers. CONSTITUTION: This method for producing a square-hole net comprises a process for knitting net legs composing the main body of the net fabric 10 with twisted yarns 11, a process for integrally knitting the net legs on both the sides of a predetermined cut line A-A having a prescribed width W and preliminarily determined along the stitch direction of the main body of the net fabric 10 with braid knitted parts 12, 13, and a process for cutting the net fabric 10 knitted in the knitting process along the preliminarily determined line to obtain the square-hole net 20 having net legs comprising the braid knitted parts on both the sides.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a square mesh.

[0002]

2. Description of the Related Art For example, in a net such as a stationary net or a ball-proof net, a square mesh in which the meshes are arranged in a vertical and horizontal series is often used. This square mesh can be obtained by knitting a cylindrical mesh having meshes arranged obliquely by a known circular knitting machine and cutting this mesh linearly along the mesh direction. it can.

However, since the conventional net cloth is generally a through-type knotless net in which the respective strands intersect at right angles, when the mesh is cut, the twists of the net legs are unwound from the cut portion and the net is separated. There was a problem of being kicked. Therefore, conventionally, as shown in FIG. 6 of the accompanying drawings, a cut thread 55 is attached to the cut net leg portion 52 (generally referred to as a beard) to the net leg portion 51 which is an end row of the square mesh 50. The work of so-called whisker pressing, which is to connect them by means of, was essential. However, this mustache pressing is currently performed manually by a skilled person, and it is a complicated and inefficient work.

[0004]

As described above, the whisker pressing work is carried out to prevent the untwisting of the net leg from the cut portion.
If the mesh fabric is constructed so that the twists of the cut legs cannot be unraveled,
Such work is completely unnecessary. From this point of view, the present inventor has proposed a novel method of manufacturing a square-mesh which can be used as a square-mesh in the cut state as it is, without untwisting the mesh leg from the cutting section, and thus without pressing down the beard. It is a proposal.

[0005]

That is, the present invention provides:
At the same time as the step of knitting the net legs constituting the main body of the net by the twisted yarn portion, and the net knitting step of the net main body, at a predetermined width along the mesh direction of the net main body. The step of integrally braiding the net legs on both sides of the planned cutting line by the braided knitting part, and cutting the net knitted by the step along the planned cutting line, and the braided part from both side rows And a step of obtaining a square-mesh having a mesh leg. The method for manufacturing a square-mesh.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a tubular net cloth showing an example of the present invention, and FIG. 2 is a square mesh obtained from the net cloth of FIG. The front view of the net, FIG. 3 is an enlarged front view of a part of the cut portion of the square mesh.
FIG. 4 is a schematic diagram showing the flow of yarn when knitting a square mesh according to the present invention, and FIG. 5 is a schematic diagram showing another embodiment.

According to the present invention, at the same time as the step of knitting the net legs constituting the main body portion of the net cloth with the twisted yarn portion and the knitting net step of the net main body portion, along the mesh direction of the main net body portion. A step of integrally knitting the net legs on both sides of a predetermined cut line of a predetermined width by a braided knitting part, and cutting the net knitted by the step along the cut line, And a step of obtaining a square mesh having mesh legs made of a braided braid in a row.

The tubular net 10 shown in FIG. 1 is a through-type knotless net knitted by a known circular knitting machine.
In this net cloth 10, the net legs constituting the main body are knitted by the twisted yarn portion 11, and at the same time as the net of the net main body, it is predetermined along the mesh direction of the main net. The net legs on both sides of the planned cutting line AA having the predetermined width w are knitted integrally by the braid knitting parts 12 and 13.

The mesh 10 of FIG. 1 has its cutting line A-.
When it is cut linearly (here, in a spiral shape) along A and opened, a square mesh 20 having a predetermined width w is formed as shown in FIG.
The mesh legs of both end rows 20a and 20b of the square mesh 20 are composed of mesh leg portions 12 and 13 which are braid mesh portions divided by the cutting line AA.

FIG. 3 is an enlarged view of a part of the cut portion AA of the square mesh material 10. As shown in the figure, the cut mesh leg 11a is firmly woven into the braided braid portion 12 or 13. It is not possible to solve it because it has been done. It will be understood that, in the conventional product shown in FIG. 6 for comparison, the twist is easily unwound from the cut knitted leg portion when it is not stopped by the stop thread 55. As shown in FIG. 3, in the square mesh material 10, the cut portion of the mesh leg 11a can be located near the root of the knitting portion with the braid knitting portions 12 and 13. It can be preferably processed from the above.

4 and 5 show that the net legs constituting the main body of the net are knitted by the twisted yarn portion, and at the same time, a predetermined cut line having a predetermined width is provided along the mesh direction of the main body of the net. It is the figure which showed typically the flow of the thread for knitting the net legs on both sides of AA integrally by the braid knitting part. The example of FIG. 4 is called a so-called four-piece set, and FIG. 5 is for forming a so-called six-piece set braid.

Reference numerals 31 and 32 are weft threads. Reference numeral 41,
Reference numeral 42 is a warp thread that is adjacent along the cutting line A-A and forms an end portion of a square mesh. The warp threads 41 and 42 may be thick threads or the like having high strength. Further, although the reference numerals 43 and 44 are warp threads which are one inside each of the end portions, the thread 43 and 44 may be a thread having high strength if necessary.
Furthermore, a braid knitted portion may be formed also on the warp yarns 43 and 44. In this case, the braided braided portion is formed in two rows at the end portion of the square mesh, and the end portion can be made stronger. Although the example of the tubular mesh is described in the above embodiment, it is needless to say that the present invention can be applied to the non-cylindrical mesh.

[0013]

As shown and described above, according to the manufacturing method of the present invention, the knitted net forming the main body of the net is knitted by the twisted yarn portion by the known knitting machine, and at the same time, the net main body is formed. The net legs on both sides of the predetermined cutting line AA having a predetermined width along the mesh direction of the part can be integrally knitted by the braid knitting part.

Since the square mesh net obtained by this method is formed by braided braid portions of parallel net legs that are adjacent to each other along the cutting line, the square mesh is cut along the cutting line. When the net is obtained, the end row of the braided net is composed of the braided braid, and the cut net leg is firmly incorporated in the braided braid and cannot be unraveled. Therefore, the end row (ear) of the square mesh is reinforced, and the conventional complicated and inefficient whisker pressing work is not required at all, and the square mesh can be used as it is in a cut state. .

Further, according to the present invention, since the end portions of the square mesh are not excessively processed as in the above, the appearance can be finished beautifully. It can be optionally reinforced. As described above, the present invention is extremely versatile and excellent in practicality as a method for producing this kind of mesh grid.
