Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of bonding audio tapes, cleaning tapes, etc., and particularly relates to a method of bonding different types of tapes such as sensing tapes.

Normally, an endless type cleaning tape 2 in a cleaner device such as an 8-track cartridge type tape recorder has a so-called sensing tape 3 made of conductive metal foil for position detection.
is pasted. This sensing tape 3 is often overlapped at the point where both ends of the cleaning tape 2 are joined, but in particular, the belt-shaped cleaning tape 2 is made of highly liquid-absorbent cloth, and the sensing tape 3 is made of metal foil such as an aluminum sheet. Since the adhesion force is weak when directly bonded, a method is used in which bonding is performed through a splicing tape 1 coated with adhesive 6 on both sides, as shown in FIG. However, in the past, the cleaning tape 2, splicing tape 1, and sensing tape 3 were simply overlapped, and as a result, the tape thickness at the tape joint increased locally, and as shown in FIG. When passing through 5,
The running load increases, and running shock, poor running, and peeling of the sensing tape 3 are likely to occur, and in the worst case, the running becomes impossible, which is inconvenient.
Therefore, the present invention improves the method of bonding the sensing tape 3 and the pricing tape 1, and provides a tape in which the thickness of the tape joint portion is reduced compared to the conventional tape.

The present invention will be explained below with reference to the drawings.

As shown in FIG. 3, both ends of a cleaning tape 2 made of cloth, paper, etc. are positioned with a certain distance between them, and the splicing tape 1 coated with adhesive 6 is superimposed on the bottom thereof. Next, a sensing tape 3 of approximately the same size as this interval is pasted from above within the above-mentioned interval between the cleaning tapes 2 to fill the interval between the cleaning tapes 2. This results in
The thickness of the tape joint is sensing tape 3.
Furthermore, since both the sensing tape 3 and the cleaning tape 2 come into contact with the splicing tape 1 during adhesion, the adhesive force is strong.

Since the thickness of the joint between the cleaning tape 2 and the sensing tape 3 can be reduced by the invention of the adhesion method described above, the increase in the load when the capstan 4, the pinch roller 5, etc. come into contact with each other while the cleaning tape 2 is traveling can be reduced. By being able to reduce the adhesive strength and having the same adhesive strength as conventional tapes, it is possible to perform good tape running.

This method can also be used when the sensing tape 3 is attached to the end of the cleaning tape 2 formed in the shape of a so-called Möbius strip by inverting both ends of the tape as shown in FIG.

As another example, as shown in FIG. 5, when it is desired to attach a magnetic reproducing audio tape 8 to a part of the reel-to-reel type cassette cleaner 7, which serves as an indicator of the running time of the cleaning tape 2. The thickness can be reduced using the method according to the invention.

Furthermore, as shown in FIG. 6, the splicing tape 1 may be made to have the same length as the cleaning tape 2. In this case, there is almost no change in thickness, and an even better product can be obtained.

In other words, the present invention is effective when joining both ends of a tape together with a small piece that is of a different type and has weak adhesion between the tapes and requires the splicing tape 1 to be interposed.

As described above, the two ends of the strip tape 2 are adhered to the adhesive coated side of the adhesive tape 1 with a certain gap between them, and different types of tape pieces are bonded within that gap from the same side as the adhesive side of the strip tape 2. Then, the local thickness of the joint can be reduced without reducing the adhesive strength of the tape, and the tape can run smoothly.
