There are known monofilament close-contact springs described in JP-A-48624 and JP-A-61-55417. An advantage of the synthetic resin wire as a spring is that it is light without being rusted, but its use is limited because it is inferior in elastic strength and shape stability as compared with a coil made of steel wire. Although the tensile strength and rigidity of the synthetic resin wire are improved by stretching, the wire diameter needs to be increased as much as possible because there is a remarkable difference as compared with metal, especially spring steel. However, there are problems that a relatively strong force is required to wind a thick wire around a thin cored bar, and that wrinkles can be formed inside the wire even if it is forcibly wound.

Therefore, a single wire having a large diameter exceeding conventional common sense of synthetic resin wire monofilaments can be used as the element wire, and therefore, it can also be used in applications where conventional synthetic resin monofilament coils cannot withstand use.

いては、撚りピッチが細かいほど小さくなる。When a synthetic resin wire is wound around a metal core to form a coil, a single wire is likely to wrinkle inside the wire,
The torsion line is less likely to wrinkle. In addition, since the spiral continuous ridge is formed on the surface of the strand, it looks like a stranded coil in appearance. In the case of a single line with a smooth surface, the degree of contact with other articles during use is large, so it has a high degree of friction and has the property of sticking easily, but there is a spiral continuous ridge on the surface. As a result, the contact area with other articles is reduced, so that the sliding property is good.
In addition, since it is a single wire, it is needless to say that the ends are not loosened like a stranded wire. The smaller the twist pitch, the larger the spring constant within the elastic limit of the coil. The characteristics of the coil can also be selected by changing the twist pitch. Still further, the hardness of the coil in the radial direction of tension or compression decreases as the twist pitch decreases.

用する際には、特に有利な性質である。 [0007] As a characteristic of a coil when the pitch is widened beyond the elastic limit, there is a case where the pitch is extremely widened in some fields of use, but the behavior of the tension depends on the torsion direction of the deformed wire. Large differences occur. In a coil with a combination of Z-twisted right-handed and S-twisted left-handed winding, when the coil is stretched, the twist increases once per pitch, so that the tension increases. Thus, the actual length of the strand increases, and the increase in tension is slow. With S-twisted right-handed and Z-twisted left-handed windings, if the pitch is greatly widened, the heat-set torsion in a twisted state will be forced back, so if the material deteriorates over time, the strands will crack vertically. There is a risk. Since the strand is stretched only in the uniaxial direction, the strength in the stretching direction is high, but the strength in the transverse direction of the strand is relatively weak, which is not preferable because the strand may be torn. Therefore, in the twisting direction of the strand and the winding direction of the coil, the two types of Z-twisted right-handed and S-twisted left-handed are excellent in both adhesion and form stability, as is clear from the above table. . Also pull the coil
When stretched, S-twisted right-handed or Z-twisted left-handed carp
The coil ends rotate with the entire coil and stretch
Work easily, but Z-twisted right-handed or S-twisted
Left-handed coils do not cause such a phenomenon.
This characteristic can be achieved, for example, by using a coil as a cable hanger.
This is a particularly advantageous property when used.

い。[0009] When the initial tension is increased by increasing the adhesion of the coil, the wire is conventionally twisted in the reverse direction of the winding direction and wound or twisted. Synthetic resin wires have basically the same effect, but the effect of the twisting direction is stronger than the winding angle. In addition, since the rigidity of the synthetic resin wire is low, unless the spring index (average coil diameter / element wire diameter) is as small as, for example, 6 or less, the coil may be broken. Therefore, it is better not to set the winding angle.

や、作業性の点で大きな問題になっている。[0010] The coil of the modified cross-section synthetic resin wire of the present invention comprises:
It is suitable for use not only as a spring but also in a long pitch coil state outside the limit of spring elasticity. For example, it can be used as a continuous cable hanger. Conventionally, in the market wiring of a cable television, a communication cable is attached to a messenger wire of a hard steel wire stranded wire stretched over a telephone pole by 40 to 50 cm.
Everything is suspended by metal cable hangers. As another method, the messenger wire and the cable are wound together with a lashing rod (spiral made of resin-coated steel wire) having a length of about 70 cm, so that the wires are bundled together. However, these operations must be manually stopped one by one using an aerial work vehicle, which is a major problem in terms of worker safety and workability.

As a concrete working method, first, when the messenger wire is wired on the power pole, a lead lobe for drawing the messenger wire and the cable through a closely wound coil having a length corresponding to the distance between the power poles is previously wired. . After fixing the messenger wire, one coil applied between the utility poles is extended to stop both ends, and finally, the cable may be pulled into the coil with a lead lobe . Such improvement in workability contributes to alleviation of traffic congestion due to the work vehicle occupying the road for a long time. In addition,
Work efficiency is improved because the coil ends do not rotate

まない。The deformed synthetic resin wire coil of the present invention has an inner diameter of 60 mm when a closely wound coil having a wire diameter of 5.2 mm and a coil diameter of 82 mm is stretched to a pitch of 150 mm between wires.
mm spiral. At that time, the force required to spread the coil is about 5 kg , and as described above,
Since the coil does not rotate during the work, it can be easily extended manually. The weight of the cable drawn into the coil is 1 even if the outer diameter of the coating is 10 mm.
Since it is about kg / m, there is no problem in the load resistance of the coil. Furthermore, regarding the resistance applied when the cable is pulled into the coil, the contact surface is small and slippery because the inner surface of the coil is a stranded wire, and the wire drawing operation is easy. Also, in the event that the coil is cut for any reason, if the coil returns to the original tight winding, there is a concern that the cable will hang down between the utility poles. It is convenient to leave the material stretched beyond the limit for a long time, since the residual strain is relaxed and does not return to the original tightly wound state. For example, the above-mentioned wire diameter of 5.2 m
m, a tightly wound coil with a coil diameter of 82 mm with a pitch of 150
Even if it is stretched to mm and both ends are fixed and stretched outdoors, and the fixing is removed one week later, the pitch does not shrink to about 100 mm or less.

As other applications, it can be used as a culvert pipe in the form of a coil wrapped with a non-woven fabric, or an underground heat exchange pipe for civil engineering and agricultural use. Because it can be folded compactly, the transportation fee is low, and it is inexpensive as a pipe and can be easily constructed.

伸加工が容易で、均質な延伸を行うことが出来る。Next, with respect to the modified synthetic resin wire coil of the present invention, a method for producing a modified synthetic resin wire serving as a strand and then a method for producing a coil will be described. The coil wire used in the present invention uses polyethylene terephthalate resin as its material. Further, as the extrusion nozzle when the molten polyethylene terephthalate resin of the material is extruded from the nozzle, an extrusion nozzle whose extrusion port is not a simple circular cross-section but has an irregularly shaped cross section having projections of various shapes around it is used. The wire with a deformed cross section extruded from the nozzle with the deformed cross section is once cooled and then uniaxially heated and drawn to obtain a deformed synthetic resin wire in which continuous ridges are formed on the surface of the wire. The nozzle having an opening with an irregular cross section used in the method for manufacturing a coil wire according to the present invention has a cross sectional shape as shown in FIG. 4 or 5, for example. It is sufficient if the shape is such that a spiral continuous ridge is formed on the surface after twisting the filament after being extruded from the nozzle, but a line-symmetrical shape with the diameter direction of the nozzle as a base line or the center of the nozzle is sufficient. It is desirable to have a point symmetric shape as a base point. You may use the nozzle of a cross-sectional shape so that the hollow of the center of a wire and other places may be formed. The size of the nozzle diameter cross section is appropriately determined so that the final product (the wire after being twisted) has a diameter of about 1.5 to 10 mm. The synthetic resin filament obtained by extruding from the nozzle having the above-described cross section, that is, the synthetic resin filament having a modified cross-section corresponding to the above-described nozzle cross-section is once cooled and solidified in the next step, and is a deformed cross section having a stable shape. It is assumed to be striated. Next, it is desirable to stretch at the time of heating in order to increase the strength of the wire. The preferred heating temperature is 80 to 120 ° C., and the preferred stretching ratio is 3.5.
About 6 times. Since the irregular cross-section filament has a larger surface area than a normal circular cross-section filament of the same cross-sectional area, the temperature difference between the surface and the center at the time of cooling and heating is small. Can be performed.

意に調節することが出来る。The wound synthetic resin wire is wound around a bobbin with a bobbin winding machine, and then attached to a strander (a rope twisting machine) as shown in FIG. The twisted wire is caused to twist,
Next, the core metal is attached to a device that can be rotated like a lathe, for example, and the element wires are wound in close contact with the rotated core metal in a line.
At this time, the wire can be supplied at a fixed angle to the pipe by a movable guide. Subsequently, the core is heated together with the core metal in a hot air heating layer in a state where both ends of the coil are fixed, water-cooled to fix the shape, and the core metal is removed to form a coil. The bending strength of the wire can be adjusted mainly by changing the cross-sectional shape and the pitch. For example, in the case of a three-stranded twisted wire, the farther apart the projections and the finer the pitch of twisting, the softer the torsion wire becomes. Conversely, the closer the center of the circle or ellipse that constitutes each projection is, the closer the entire outer shape is to a circle, and the coarser the pitch of torsion, the stronger the torsion line and the greater the bending strength are obtained. The resulting synthetic resin wire coil thus obtained has a spiral continuous ridge formed on the surface of the element wire, and thus looks like a stranded wire coil in appearance. In addition, in the case of a single wire having a smooth surface, the degree of contact with other articles during use is large, so that the degree of friction is large or it is easily adhered.However, there is a spiral continuous ridge on the surface. Since the contact area with other articles is small, the sliding property is good. In addition, since it is a single wire, it is needless to say that the ends are not loosened like a stranded wire. In addition, a coil having the above-mentioned single wire of the deformed synthetic resin as a strand can be continuously produced in a much simpler process than that of a stranded coil. The bending strength of the dovetail wire, the tensile strength of the coil and the like can also be arbitrarily adjusted.
