本発明は絶縁ケーブルのテープ巻方法の改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a tape winding method for an insulated cable.
OFケーブルで代表される絶縁ケーブルでは紙，
プラスチツクフイルム等のテープ状絶縁体を数＋
〜数百枚巻付ける作業が行われる。 Insulated cables such as OF cables use paper,
Several tape-shaped insulators such as plastic film
~The work of winding several hundred pieces is performed.

は極めて重要である。 Conventionally, in the above-mentioned tape winding method, the tape was wound carelessly without paying attention to the relationship between the direction of the selvedge part M of the tape and the winding direction of the paper winding machine. (Typically wound in the same direction) Figures 2A and 2B are explanatory views of the state of the tape wound around the conventional cable core, cut in the axial direction and enlarged. The lower side is the cable conductor side. If the selvage part M is facing upward as shown in Fig. B or downward as shown in Fig. A, in the same direction, the layer change point (A
- In the part of line B), the selvedge part M falls into or gets stuck in the gap g, so if the cable is bent, the paper tape will not slide easily against each other, and wrinkles will occur on both sides of the paper tape. In extreme cases, it may tear and cause the cable's pressure resistance to deteriorate. Therefore, it is extremely important to prevent this phenomenon.

とするものである。 In view of the above points, the present invention has been developed by winding either the upper layer or the lower layer inverted by 180 degrees at each portion where the winding direction of the bent portion of the insulating tape changes during tape winding. The purpose of this is to prevent wrinkles and tears in a tape having a laminated structure.
以下図面に示す実施例により本発明を説明す
る。 The present invention will be explained below with reference to embodiments shown in the drawings.
第３図イはテープ切断部の耳かえり部Ｍが導体
側に向つて配置されている場合を示し、同ロ図は
耳かえり部Ｍがケーブル表面側を向いている場合
を示す。 FIG. 3A shows a case where the selvedge part M of the tape cutting part is arranged toward the conductor side, and FIG. 3B shows a case where the selvedge part M faces the cable surface side.

では下層の上の１枚のテープT2を180゜反転させて
巻付けるようにしたものである。 That is, in the present invention, in any case, at the part where the gap g of the tape intersects at the layer transition point shown by line A-B, the upper layer is The lower layer of tape T 1 is reversed by 180 degrees and wound, and in the case of figure B, the upper tape T 2 of the lower layer is reversed by 180 degrees and wound.
本発明は上記のようなテープの巻付け方法を施

防止することが出来る利点がある。 The present invention employs the above-described tape winding method, so that even if the tape moves when the cable is bent, the selvage parts M of the tape will not slide against each other at the part where the gap intersects at the transition point between layers. This has the advantage that wrinkles and cracks caused by the selvage portion can be prevented from occurring.

Figures 1A and 2B are explanatory diagrams of how burrs are formed on the tape when the tape is cut. Figures 2A and 2B are diagrams showing the state of tape wound around a conventional cable core, cut in the axial direction. FIGS. 3A and 3B show enlarged explanatory views cut in the axial direction of the tape subjected to the method of the present invention. T is a tape, M is a selvedge part, T 1 and T 2 are tapes to which the present invention has been applied, and the line A-B shows a transition point between layers.
