Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape-shaped woven wire mesh in which a web (so-called web) of a woven wire mesh and fray stoppers are formed on both side edges, and a method for producing the same.

[0002]

2. Description of the Related Art To manufacture a woven wire mesh, conventionally,
A method of once weaving a raw fabric of a normal woven wire mesh, slitting it, and cutting it into a tape having a predetermined width in parallel with a vertical line has been adopted.

[0003]

However, the tape-shaped woven wire mesh obtained by the above-described method tends to have vertical lines frayed on the cut side edges, and once frayed, the vertical line deviates from a predetermined standard width. There was a problem that the quality of the product deteriorated and handling during rework became difficult.

Accordingly, an object of the present invention is to provide a woven wire netting, a tape-shaped woven wire mesh, and a method for manufacturing the same, in which when cutting a woven wire mesh to produce a tape-shaped woven wire mesh, both side edges are hardly frayed. To provide.

[0005]

In order to solve the above-mentioned problems, a woven wire mesh according to the present invention opens two adjacent vertical lines at predetermined intervals in the width direction of the wire mesh on both sides, and each of these vertical lines is opened. By making the line close to another vertical line adjacent on both sides, a configuration is adopted in which the interval between the two adjacent vertical lines is wider than that between the other vertical lines.

Further, the tape-shaped woven wire gauze of the present invention employs a configuration in which the vertical lines on both sides are brought close to the inner vertical lines, respectively, and a fray stopper is formed at each side end.

Further, in the manufacturing method of the present invention,
Two adjacent vertical lines at predetermined intervals in the width direction of the wire mesh are opened on both sides at the reed part, and are passed through other passing openings adjacent on both sides, so that the intervals between the vertical lines are at predetermined intervals. A woven wire mesh is formed in which a wider portion is formed than the interval between the other vertical lines, and two vertical lines are close to each other on both sides of the wide portion to form a fray-stop, and then the horizontal line of the wide portion is cut. As a result, fray stoppers were formed on both side edges of the tape-shaped woven wire mesh.

[0008]

According to the present invention, when the woven wire mesh is cut in parallel with the vertical wire to produce a tape-shaped woven wire mesh, the vertical lines on both side edges of the tape-shaped woven wire mesh are close to the vertical wire of the wire mesh. , Compared to the part with the normal vertical line spacing, the bending of the horizontal line is larger, and because the two vertical lines are close to each other, the horizontal line is more strongly sandwiched between the vertical lines, preventing fraying can do.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

A plain woven wire mesh is manufactured as follows using a wire mesh loom as shown in FIG. First, a number of vertical lines 2 drawn from the warping beam 1 are aligned in parallel via a guide roll 3 and a back-top roll 4, and a group of every other vertical line from the end and a group of the remaining vertical lines are formed. The healds are divided into two groups, and are passed through a pair of front and rear healds 5 (so-called Kasari) corresponding to each group, and all the healds coming out of each heald are passed through the passage of the reed 6.
The healds 5 can move up and down, respectively, and as shown in FIG. 2, by moving the pair of healds 5 up and down in opposite directions, an opening 7 is formed between the vertical lines. The horizontal line 8 is passed through the opening 7, and the horizontal line 8 is woven between the vertical line groups using the reed 6. Next, the pair of healds 5 is moved up and down to a position opposite to the previous position. Thereby, a new opening is formed between the vertical lines, a horizontal line is passed through the opening, and the horizontal line is woven between the vertical line groups by the reed 6. As described above, each time the pair of healds 5 is repeatedly moved up and down, an opening is formed, and each time the opening is formed, a horizontal line is passed through each line, and the horizontal line 8 is woven between the vertical line groups by a reed. To manufacture plain weave wire mesh.

In order to efficiently weave the horizontal lines, a rapier type in which continuous horizontal lines are cut and woven one by one is adopted. Gear 2 in rapier 22 (ie, horizontal line insertion device)
As the 4 rotates, the rapier band 25 engaged with it moves, and the rapier head 23 grabs the horizontal line 8 on the opposite side of the vertical line 2. The horizontal line 8 is then passed to the side where the rapier 22 is located by the rotation of the gear 24 in the opposite direction. Then, although not explicitly shown in FIG. 1, the horizontal lines 8 are cut at both ends of the vertical line 2 by a cutter, and are woven by the reed 6. According to this rapier type, since the vertical lines on both side edges are easily frayed, as shown in FIG.
a is formed close to the inner vertical line 2b and passed through the same reed passage to form the fray stopper 9.
By bringing two vertical lines close to each other, the horizontal line has a greater bending than a case where the vertical line has a normal vertical line interval,
Since the horizontal line is more strongly sandwiched by the vertical line, fraying can be prevented.

When a plain woven wire mesh is cut in parallel with a vertical line to produce a tape-shaped plain woven wire mesh, as shown in FIG. 3, predetermined gaps are provided in the width direction of the wire mesh to form fray stoppers on both side edges to be cut. Then, the two adjacent vertical lines (2d, 2e) are opened on both sides by the reed 6, and are passed through the other passing openings adjacent on both sides thereof, and are respectively brought close to the adjacent vertical lines. That is, the vertical line 2d is brought close to 2c, and the vertical line 2e is brought close to 2f to form a fray stopper. In this way, a plain woven wire mesh 20 having a fray preventing portion in the wire mesh is obtained, and can be used as a raw material of the tape-shaped plain woven wire mesh. As shown in FIG. 4, the above-mentioned raw material includes two adjacent vertical fray stoppers 9 each having a vertical line (2 a, 2 b) and a width of another adjacent vertical line at a predetermined position inside. The structure has a wider vertical line (between vertical lines 2d and 2e) and two vertical lines (vertical lines 2c and 2d and vertical lines 2e and 2f) close to both sides. A tape-shaped plain woven wire net 21 having a fray-stopped portion formed on both side edges by cutting the above-described web into a wide portion between vertical lines (between the vertical lines 2d and 2e) as a cut line 18 and cutting this portion. (FIG. 5) can be obtained. The cutting is performed as follows. That is, as shown in FIG. 1, the wire mesh woven by the reed 6 passes through the front top roll 11, the press roll 12, and the guide roll 13, and is prevented from winding by the winding prevention roll 14. When the wire mesh is wound by the roll 15, a cutter 16 is set in front of the curling prevention roll 14, and the position of the cutting blade 17 is set in the cut line 18 during the cutter, thereby forming a tape-shaped plain-woven wire mesh. Is wound up on a winding roll 15. The cutter 16 has a cutting blade 17 as shown in FIG. 6, and a holding block 19 of the cutting blade 17 can be moved to match a predetermined cut line 18.

By setting the cutter 16 at the above position, a tape-shaped plain woven wire mesh can be manufactured in a wire mesh loom. In addition, the raw material is wound around a take-up roll without attaching a cutter. You may let it. In this case, if necessary, it may be cut later using a cutting device such as a slitter, if a cutter is not installed on the wire mesh loom, or if the above-described web is cut at a location different from the web manufacturing location. Can be used.

Further, in the case of the twill-woven wire mesh, as in the case of the plain-woven wire mesh, the horizontal line is woven into the vertical line, so that the twill-woven wire mesh is also unraveled in the wire mesh in the same manner as in the case of the plain-woven wire mesh. The stopper can be formed, and a tape-shaped wire mesh can be manufactured.

[0015]

As described above, the tape-shaped plain woven wire mesh thus obtained is provided with fray stoppers on both side edges, thereby preventing fraying on both side edges. In addition, a high-quality product can be manufactured without deviating from a predetermined standard width due to fraying, and handling during rework is facilitated.
