紙１４を貼り合せることもある。 Conventionally, these composite tapes were connected to each other by a method as shown in FIG. In the figure, numerals 11 and 11 are composite tapes to be connected, which are made by laminating kraft paper 13 on both sides of a plastic film 12. The connection is performed by butting the ends of the composite tapes 11, 11 together and pasting thin (20 to 100 μm) kraft paper 14 on both sides of the abutting portion using an adhesive. Note that thin kraft paper 14 may be pasted only on one side of the abutting portion.

１４が切れてテープ切れを起し易い欠点がある。 However, in this method, since the connection kraft paper 14 is pasted on the outside of the connection part, this part becomes locally thick and tends to create local discontinuities in the power cable after the conductor is wound. Also, when it thickens locally,
That part becomes locally hard, and when it passes through various rollers just before being wound onto the conductor, it is unable to follow the radius of curvature of the rollers, and the connecting kraft paper 14 breaks at the connection part, causing the tape to break. There are some easy drawbacks.

いてしまうことがある。 In addition, when connecting the above-mentioned base paper rolls, the thin kraft paper 14 is generally adhered to the outside of the connection part using a natural water-soluble adhesive, so that the adhesive passes through the connection kraft paper 14. The tape may smudge, and the kraft paper of the composite tape on the outer layer or the inner layer and the connecting kraft paper 14 may get stuck together. In particular, when the kraft paper of the composite tape is moistened and used as known in Japanese Patent Publication No. 52-38237 as a measure against swelling of the composite tape in oil, the adhesive may be dry at first. However, over time, it absorbs moisture and softens, and eventually oozes through the connecting kraft paper 14 into the outer layer or the inner layer, and as mentioned above, the connecting kraft paper becomes the kraft paper of the composite tape in the outer layer or the inner layer. Sometimes I get stuck.

てしまう恐れがある。 If it is plucked as described above, when the paper winding machine starts winding the conductor, the kraft paper of the outer layer or the inner layer of the composite tape will be peeled off starting at the point where it was plucked, and it will no longer look like a composite tape. There is a risk of losing it.

程度であるから、この作業は容易である。 Hereinafter, the present invention will be explained by examples using the drawings. FIGS. 2A to 2F are longitudinal cross-sectional views of a connecting portion for explaining an embodiment of the method of the present invention. In the figure, 1 and 1' are composite tapes to be connected,
Kraft papers 3 and 3' are laminated on both sides of plastic films 2 and 2', respectively. These composite tapes 1 and 1' are first coated with kraft paper 3 (or 3') on one side of the terminal part or with plastic film 2 (or 2'), depending on the form of the respective connection parts shown in Figures A to F. is removed and cut into steps (hereinafter, this operation is referred to as "step peeling"). In this case, since the adhesive force between the kraft paper 3 (or 3') and the plastic film 2 (or 2') of the composite tape is such that it can be peeled off manually, this operation is easy.

好ましい。 In the method shown in Fig. 1, the end portion 4 of the composite tape 1 on one side is cut and removed by peeling off the kraft paper 3 on one side, and the end portion 4' of the composite tape 1' on the other side is separated from the kraft paper 3' on one side and the plastic. After peeling off the film 2' all at once and cutting it to the same length as the kraft paper 3, the tapes 1 and 1' on both sides of these peeled steps are connected, and the plastic films 2 and 2' on both sides are brought into contact with each other. The plastic film 2 and the kraft paper 3' are placed one on top of the other, and the inside surfaces of this overlap are bonded together with an adhesive 5. During this bonding, if heat is applied with an iron or the like from above the kraft paper 3', moisture in the adhesive 5 will be absorbed into the kraft paper 3'.
Because it comes out easily through the adhesive, it dries and hardens quickly after being applied. As the adhesive 5, for example, natural water-soluble rubber glue, starch glue, etc. are preferable because they do not deteriorate the electrical properties after being immersed in oil, are inexpensive, and are easy to handle.
この方法によると、接続部の厚さ増加は無い。
なお複合テープ厚がうすい場合、片面接続で強度
は充分である。 According to this method, there is no increase in the thickness of the connection part.
Note that if the composite tape is thin, one-sided connection will provide sufficient strength.

２個所となるので、接続はより強固となる。 The method shown in Fig.
The end portions 4, 4' of the kraft paper 3,
3', the plastic films 2 and 2' are peeled off in this order, and the cut lengths of the kraft paper 3 and 3' are made longer and the cut lengths of the plastic films 2 and 2' are made shorter and the steps are peeled off. The tapes 1 and 1' are connected, the plastic films 2 and 2' on both sides are pressed together, the plastic film 2 or 2' and the kraft paper 3' or 3 are overlapped, and the inside surfaces of these overlaps are coated with adhesive 5. , 5 are pasted together in the same manner as in Figure A. In the case of this method as well, there is no increase in the thickness of the connection part, and since there are only two adhesives, the connection becomes stronger.

である。 In the method shown in Figures A and B above, when there is no risk of the adhesive oozing through the kraft paper 3, 3', that is, when the composite tape is not subjected to humidity control treatment, the amount of kraft paper compared to the amount of adhesive is 3,
If 3' is thick, if kraft paper 3, 3' is thin, there is enough time to dry it after adhesion and there is no risk of smearing, or if you do not have enough time to dry it with humidity control treatment or use thin paper. Even if the composite tape is connected, it will not cause any damage to the composite tape.
For example, it is effective when applied to the connection of composite tapes fed from one tape pad in a paper roll of a paper winding machine.

ラフト紙１枚分増加するが、外側のクラフト紙３
は接着剤５が外側ににじみ出すのを防止する。 The method shown in Figure C is to leave the kraft paper 3 on one side of the end portion 4 of the composite tape 1 on one side in Figure A by peeling it off without cutting it, and leaving the adhesive overlapping surface 6 of the plastic film 2 and the kraft paper 3'. The outside of the paper is covered with the peeled kraft paper 3. In this way, the thickness of the connection part increases by one sheet of kraft paper, but the thickness of the outer kraft paper increases by 3
prevents the adhesive 5 from seeping outward.
