ものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bonding structure for adhesive tapes that lose their release effect due to heat and a method for manufacturing diapers. The adhesive tape is used for applications in which a release-treated surface and an adherend are to be bonded, and specifically, it is not limited to tape systems for attaching disposable diapers, but is also used for stationery, sanitary materials, medical supplies, etc. It can also be effectively used for materials.

る。BACKGROUND OF THE INVENTION Conventionally, various adhesive tapes have been used as means for securing disposable diapers, but if the adhesive strength of the adhesive tape is weak, it is impossible to securely secure the disposable diapers.
The tape may separate from the diaper, making it unsuitable for practical use.

A tape-type fixing structure disclosed in Japanese Patent No. 34978 is known. In this conventional example, the front and back parts of the Y-shaped tape are
The tape is attached individually to the front and back surfaces of the side edges of the diaper, and the fixing portion of the tape is used as a means for attaching the diaper.

って、幼児の肌を傷付けるおそれがある。However, in this conventional example, the fixing part of the tape is bent and overlapped with the surface part of the tape, so bending takes time and the manufacturing process becomes complicated. Moreover, since the tapes are overlapped, the thickness of the fastening portion of the diaper increases, and as a result, the fastening portion becomes hard and may damage the infant's skin.

その結果、該止着部分が硬くなるのを防止できるという
メリットが生じる。On the other hand, as a second conventional example,
A sanitary article disclosed in Japanese Patent No. 95105 is known. In this conventional example, one end of the tape (fastening piece) is sandwiched between the top sheet and back sheet of the diaper to adhere them to each other, and the tensile force applied to the tape is distributed between the top sheet and back sheet. In addition to preventing the tape from coming off, since the tape does not have a double structure unlike the first conventional example, the thickness of the portion where the diaper is attached can be reduced. As a result, there is an advantage that the fastening portion can be prevented from becoming hard.

布する工程が必要となる。However, in the second conventional example, an adhesive is applied to both the top sheet and the back sheet of the diaper, and then a tape is adhered to the applied area. Therefore, a step of applying adhesive to two locations on the diaper is required.

ことができない。[0007] When applying the adhesive to the sheet surface, if the thickness of the adhesive is not set uniformly, the adhesive force with the tape will weaken, causing the problem that the tape will come off during use of the diaper. However, adhesives are generally susceptible to conditions such as temperature and dryness, and it is difficult to control their thickness. Therefore, it takes time and effort to adjust the thickness of the adhesive, and the process of applying the adhesive cannot proceed smoothly.

This has the disadvantage of causing a decrease in efficiency.

The purpose of the present invention is to provide an adhesive tape bonding structure and a diaper manufacturing method that can facilitate the process.

ことに成功した。[Means for Solving the Problem] After extensive research, the inventor applied a release treatment to one or both sides of the tape, and applied heat to the release treatment surface to an adherend such as a synthetic resin film or nonwoven fabric. By focusing on the fact that when bonded, the release effect is lost and the effect shifts to an adhesive effect, even a single-sided tape coated with a conventional adhesive on only one side can be used as a separator-less double-sided tape. Furthermore, it has been found that even a tape that has been subjected to release treatment on both sides can be used as a double-sided tape. In addition, when performing mold release treatment using a long-chain alkyl mold release agent, the mold release agent is generally less affected by conditions such as temperature and dryness than adhesives, and its thickness can be controlled. It was found that it was easy to do this, and as a result, it was possible to prevent troubles as much as possible during the adhesive tape release process.

。[0011] Through further research, the inventor found that when the adhesive tape was used as a diaper fastening tape, the adhesive strength between the diaper fastening part and the adhesive tape, especially the shear adhesive strength, was significantly improved. understood. Moreover, as mentioned above, it is possible to prevent troubles from occurring during the release process of adhesive tapes, so we discovered that even when the adhesive tape manufacturing process is directly connected to the diaper manufacturing line, manufacturing can be made smoother. This led to the completion of the invention.

As shown in FIG. 1, the adhesive tape has, for example, a release-treated surface 3 formed on one side of a base material 2, and a conventional adhesive 4 coated on the other side. Further, the left half of the adhesive tape 1 is sandwiched between a top sheet 6 and a back sheet 7 at the side end portion of the diaper 5, and the release-treated surface 3 is bonded to the top sheet 6 side by thermal adhesion.

Ru. This mold release agent is pattern-coated over a portion or the entire surface of one or both sides of the tape, and in the next step is thermally bonded to the side edges 5a, 5b of the diaper as shown in FIG.
