いる。一部の電線はダンボール箱に収納している。2. Description of the Related Art Most bundled electric wires used for indoor and outdoor low-voltage wiring in buildings, houses, and factories employ a method in which kraft paper A is wrapped in a layered form along an extruded nut-shaped bundle. Some wires are stored in cardboard boxes.

抱えている。[Problems to be Solved by the Invention] In the case of wrapping kraft paper, it takes time and effort to unwind the wrapped kraft paper, and since the wires cannot be seen from the outside, erroneously delivering a different bundle of wound wires to the site. I have a misdelivery problem.
【０００４】なお、ダンボール箱はコストが高いため、
小さな束巻き電線に一部使用されているだけである。[0004] Since cardboard boxes are expensive,
It is only partially used for small bundled wires.

【課題を解決するための手段】本発明は、包装を解くこ
となく電線を繰り出せ、且つ包装したままで内部の電線
を確認できる束巻き電線に関するものである。SUMMARY OF THE INVENTION The present invention relates to a bundled wire in which an electric wire can be paid out without unwrapping, and the inner electric wire can be checked while being packed.
【０００６】熱収縮プラスチックシートを束巻き電線の

明では、電線束の外円周方向にのみ熱収縮する１軸延伸
熱収縮プラスチックシート（Ｃ）を使う。When the heat-shrinkable plastic sheet is covered on the entire surface of the bundled electric wire, wrinkles frequently occur after the heat-shrinkage. Therefore, in the present invention, the uniaxially stretched heat-shrinkable plastic sheet heat-shrinks only in the outer circumferential direction of the electric wire bundle. Use (C).
【０００７】電線束（Ｂ）の高さ（７）より幅の広い熱

穴明きとする。[0007] A heat-shrinkable plastic sheet wider than the height (7) of the wire bundle (B) is placed on the outer circumference (1) of the wire bundle.
And the sheet overlap portion (8) is integrated by heat fusion. The inner surface (5, 6) of the central portion of the wire bundle is perforated without the sheet.

レンテレフタレートが適していることが判明した。更に
強度を上げるためには、ポリエチレンとポリプロピレン
またはポリエチレンテレフタレートをラミネートすれば
よい。It has been found that polyethylene and polypropylene polyethylene terephthalate are suitable as the material of the heat-shrinkable plastic because of its strength, ease of heat shrinkage, and no generation of harmful gas during incineration. To further increase the strength, polyethylene and polypropylene or polyethylene terephthalate may be laminated.
【０００９】また、熱収縮前のプラスチックシートの厚

００μｍを越えると従来のクラフト紙包装より不経済と
なることから５０〜２００μｍとすることが望ましい。The thickness of the plastic sheet before heat shrinkage must be 50 μm or more from the viewpoint of strength.
If it exceeds 00 μm, it is more uneconomical than conventional kraft paper packaging.
【発明の効果】本発明は、以上説明したように構成され
ており、以下に記載されるような効果を奏する。The present invention is configured as described above, and has the following effects.
【００１０】プラスチックシートが１軸延伸であるこ
と、電線束の内面を包被していないことから熱収縮後も
プラスチックシートにはシワが生じない。Since the plastic sheet is uniaxially stretched and does not cover the inner surface of the wire bundle, the plastic sheet does not wrinkle even after heat shrinkage.
【００１１】電線束中央を穴明きとしているため、包装
を解くことなく電線を繰り出すことができる。Since the center of the wire bundle is perforated, the wire can be paid out without unpacking.
【００１２】プラスチックシートを透明若しくは半透明
とすれば、包装したままで内部の電線を確認することが
でき、誤送を防止できる。If the plastic sheet is made transparent or translucent, it is possible to check the electric wires inside the package as it is, thereby preventing erroneous transmission.

製造方法。1. A method for producing a bundle wound wire comprising a VVF wire (flat vinyl insulated vinyl sheathed cable) or an IV wire (indoor vinyl wire), wherein a uniaxially stretched heat-shrinkable plastic sheet having a width larger than the thickness of the bundle is used. After the heat-shrinking direction is matched with the outer circumferential portion of the wire bundle and wrapped along the outer circumferential portion, the sheet connecting portion is integrated by heat fusion, and then the heat-shrinkable sheet is heat-shrinked. A method for manufacturing a bundled wire in which the outer surface of the wire bundle is tightly covered except for the hollow portion of the wire bundle.
