術上の問題として残されている。2. Description of the Related Art Steel cords for reinforcing rubber products are generally formed by twisting a plurality of cords, but the strength of the cords is improved, the weight is reduced, and the production cost of the steel cord is reduced. Effective in reducing, the steel cord is thin, and therefore has anisotropic bending stiffness, high transverse bending stiffness and low longitudinal bending stiffness, significantly improving tire performance For this reason, a plurality of cords are arranged and arranged in a plane, and a thin wrapping wire is spirally wound around the steel cord. The steel cord has been developed and put into practical use. An example of this is disclosed in JP-A-62-149.
929 and JP-A-63-240402. As shown in FIGS. 7 and 8, this has a simple structure in which a plurality of straight cord wires 1 are arranged on a plane and a wrapping wire 2 is wound around the wires. Therefore, there remain problems such as low fatigue resistance. In order to improve the characteristics of the steel cord, there has been known a steel cord in which the elasticity in the longitudinal direction of a steel cord is enhanced by applying a wavy pattern (Japanese Patent Application Laid-Open No. H8-120578). Although it is certain that the above-mentioned conventional one increases the elasticity in the longitudinal direction, the following problems remain. That is, the wrapping wire has a thickness (for example, 0.15 m).
m) protrudes from the surface of the steel cord by
Also, since there is no entanglement with the cord, the degree of freedom in the longitudinal direction of the cord with respect to the cord surface of the wrapping wire is large, and therefore, it is weak against ironing, the shape is unstable, and the winding or unwinding at the time of cord production, The wrapping wire is easily cut by rubbing with a guide or the like, and the handling workability is poor. Further, the wrapping element and the cord are rubbed during running of the tire, causing fretting wear. In addition, the cord width increases by the amount that the wrapping wire protrudes from the side surface of the cord, and although the wire diameter of the wrapping wire is small, several hundreds of wires are aligned. The effect of the decrease in the number of embedded lines is large. In order to solve the problem of this conventional example,
In order to prevent the wrapping wire from projecting from the cord surface and to reduce the degree of freedom of the wrapping wire in the longitudinal direction of the cord, the wavy shape of the steel cord in the width direction (horizontal direction) and the thickness direction (vertical direction) is used. And invented a steel cord having a novel structure in which a wrapping wire is wound along a valley of a waveform. The steel cord of this new structure is a flat structure, with a wrapping wire wound around it with the waveforms in the horizontal direction (width direction of the steel cord) and the vertical direction (thickness direction of the steel cord) aligned. Therefore, it is not easy to form the flat shape due to the collapse of the flat shape due to the tightening force of the wrapping wire, and how to form it accurately and efficiently is a technical problem. Has been left as.

よい。[Operation] After applying a waveform in the horizontal direction to each of the code strands, aligning the phase of the waveform, aligning a plurality of code strands, and wrapping the wires at the same pitch as the horizontal waveform. , The wrapping element wire is wound around the valley portion of the wavy pattern, and a plurality of cord elements are bundled. This steel cord is pressed in the vertical direction (thickness direction) by, for example, a large number of pressing rollers arranged in a staggered manner in the vertical direction (thickness direction), thereby flattening the steel cord and forming a waveform in the vertical direction (thickness direction) at the same pitch. , The steel cord becomes a corrugated steel cord in the horizontal direction (width direction) and the vertical direction (thickness direction). The steel cord formed as described above becomes a corrugated steel cord having the same pitch in the width direction and the thickness direction, and the wrapping wire in both the horizontal direction (width direction) and the vertical direction (thickness direction) It fits into the valleys of the corrugations and fits inside the apparent outer surface of the steel cord. Since the process of applying the horizontal waveform is performed at the stage of the cord strand, the horizontal waveform is applied very easily, easily, and accurately. By wrapping the wrapping wire at the same pitch while aligning and aligning the pitch, the wrapping wire naturally fits into the valley of the waveform, so the winding work of the wrapping wire is accurate and efficient. At this stage, since the wrapping wire is fitted into the valley of the corrugation in the horizontal direction at this stage, the wrapping wire is firmly and stably engaged with the cord in the longitudinal direction. As described above, the wrapping element wire is fitted into the valley of the waveform in the horizontal direction and is securely and stably wound, and a bundle of a plurality of cord elements is bundled,
It is flattened through a pressing means such as a pressing roller, and it is given a wavy shape in the vertical direction (thickness direction). When the wavy shape is applied in the vertical direction, the wrapping wire slips in the longitudinal direction of the steel cord and collapses. And the wrapping wire is securely fitted into the valley portion of the vertical waveform formed by the pressing means. Note that, as long as the waveform in the horizontal direction applied to the cord element has a waveform on a plane, the above-described effect is achieved. Therefore, a small spiral waveform may be used in addition to the so-called waveform waveform.

The steel cord for reinforcing rubber products in this example is obtained by wrapping three wrapping wires 1 around a wrapping wire 2 and arranging the wrapping wires 2 on a plane.
mm, and the diameter of the wrapping wire is 0.15 mm. Each of the cord strands is subjected to a wavy waveform (see FIGS. 2 and 4) having a wave height of 0.5 mm and a pitch of 5 mm in a lateral direction.
The wrapping wire is wound at a winding pitch of 5 mm.
While the wrapping wire is wound, the steel cord is pressed in the vertical direction to flatten it, and the steel cord is given a vertical waveform of 5 mm pitch (see FIGS. 1 and 3).
The wrapping wire is wound along the vertical wavy valley and in the horizontal wavy valley, and the relationship between the cord and the wrapping wire is as shown in FIGS. .
That is, in the AA cross section of FIG. 4, the wrapping strand is at one end of the steel cord (FIG. 5, AA),
It is on the back side of the steel cord in section B (Fig. 5, B
-B), at the other end of the steel cord in the CC section (FIG. 5, CC), and further on the surface of the steel cord in the DD section (FIG. 5, DD). As described above, since the wrapping element wire 2 is within the apparent thickness T of the steel cord, the wrapping strand 2 fits inside the apparent front and back surfaces of the steel cord (FIG. 5, BB, DD), and ,
The wrapping strand is wound along the valley of the wavy wavy line in the horizontal direction, and is within the apparent width W of the steel cord, so that it is contained inside the apparent side surface of the steel cord (FIG. 5, A). -A, CC). Three payout reels 6
The code strand 1 fed out from the line 1 is given a waveform by a wave customizing device 62.
And the three twisted cords are passed through a wrapping machine 63, passed through a pressing device 64, and finally wound up by a take-up reel 65. The three wrapping wires are aligned by the wrapping machine 63 in a state where the phases of the waveforms are aligned, and the wrapping wires 2 are relatively loosely wound around the valleys of the waveform at the same pitch as the waveforms. Be bundled. By passing the bundled material through a pressing device 64 in which five rollers are arranged in a staggered manner vertically, the bundle is pressed in the vertical direction to be flattened and has a wavy shape in the vertical direction. As a result, a steel cord which is flat and corrugated in the vertical direction (thickness direction) is formed. At this time, the winding pitch of the wrapping wire is equal to the vertical (thickness direction) wavy pitch,
The wrapping wires are fitted along the valleys of the waveform. The above embodiment is an example of a manufacturing method in a case where cords are arranged in a horizontal row to form a single step. For example, when a cord in which three cords are stacked in two steps is produced, a flat steel sheet is used. The width of the cord is restricted to three cord strands by the pressing roller of the pressing device.
What is necessary is just to pass a bundle of the cord strands by the wrapping strands through a pressing device by the pressing roller.

Since the wavy processing is performed, the wrapping strand does not shift with respect to the cord in the longitudinal direction,
Therefore, the forming accuracy is high, and the shape of the finished steel cord is stable. In addition, the wrapping process is performed at the stage of the cord strand, and the wrapping machine aligns the phases of the waveform, aligns the phase, and winds and wraps the wrapping strand to provide excellent workability and work efficiency. ,
As described above, the flattening process and the vertical (thickness direction) corrugation process are performed through the pressing device while the wrapping element wire is wound, so that the flattening process and the vertical direction (thickness direction) are performed. Can be stably and efficiently performed. The steel cord manufactured by the above manufacturing method has the following advantages. Since the wrapping wire is wound around the valley of the corrugated cord, the wrapping wire is firmly fixed, the shape of the steel cord itself is stabilized, and the handling workability is improved. Also, since the wrapping wire is fitted in the valleys of the cord in the vertical and horizontal directions of the cord, the wrapping wire does not slide in the longitudinal direction of the cord to cause fretting wear. Since it is also possible to avoid applying excessive force to the wrapping wire by winding, feeding, etc.,
There is no problem that the wrapping wire is broken. In addition, since the wrapping wires are fitted into the valleys of the wavy lines in the vertical and horizontal directions, the width and thickness of the steel cord are prevented from increasing due to the wrapping wires protruding from the surface of the cord. As a result, the number of steel cords per unit width that can be embedded in the rubber product can be increased, and the reinforcing strength can be increased.
