である。 One embodiment will be described based on the drawings. The manufacturing method of the present invention includes a known high-frequency welding machine that includes a blade mold 2 having a blade 2' corresponding to the outer circumference 1' of a band body 1, and a blade mold 2 having a blade 2' corresponding to the outer circumference 1' of a band body 1. A receiving mold 3 facing the mold is installed, and the receiving mold 3 is provided with a cylindrical part 4 of a band body into which a fixing pin or the like is inserted along the tip, and a natural or A band material 6 made of a flexible material such as synthetic leather or fiber is placed before the band body 1 is welded and cut, and the receiving mold 3 is placed on the cylindrical portion 4 of the band body.
The cylinder part 7 corresponding to the cylinder part and the main body part 7' corresponding to the main body part 4' of the band body excluding the cylinder part are divided and configured to be movable, and the blade mold 2 is pressed against the band material 6. When welding the front and back materials 5, 5' along the outer circumference 1' of the band body using the blade mold 2 and the receiving mold 3 as electrodes,
The cylindrical part 7 of the receiving mold is set further apart from the main part 7',
By providing a gap 8 between the cylindrical part 4 of the band body and the receiving mold, only the main body part 4' of the band body is welded, excluding the cylindrical part 4 of the band body, and the blade mold 2 is further pressed to form the band. When cutting the outer periphery 1' of the body, the cylindrical part 7 or the main body part 7' of the receiving mold slides so that the cylindrical part and the main part are on the same plane, so that the cylindrical part 4 and the main part 4' of the band body are separated. It is characterized by cutting simultaneously.

A welded inclusion such as a nylon film or a nonwoven fabric is interposed between the front and back materials 5 and 5', and 9' is a butting portion of the front and back materials 5 and 5'. Note that the front and back materials may be the same material or different materials, and it is convenient to temporarily weld or adhere the entire surface of the main body 4' in a polymerized state.For welding the entire surface, use a press mold instead of the blade mold 2 of the embodiment. It can be easily welded by using.

る。 The blade mold shown in FIG. 4 and the receiving mold shown in FIGS. 4 to 7 show the general structure, and the receiving mold 3 shown in FIGS. An example is shown in which the body part 7' is movably configured, and when welding, the main body part 7' is pushed up by hydraulic pressure or spring pressure, etc., as shown in Fig. 4, and a step is provided on the cylindrical part 7 to form a step shape, and when cutting. In this case, the main body part 7' is lowered as shown in Fig. 5 without using hydraulic pressure, etc. (or the main body part is lowered by the pressing force of the blade 2), and the cylindrical part 7 is made flush. .

のである。 The receiving mold 3 in Fig. 6 shows another embodiment in which the cylindrical part 7 is configured to be movable, and when welding, the cylindrical part 7 is stepped against the main body part 7' as shown in Fig. The tubular portion 7 is made into a step-like shape, and when cutting, the cylindrical portion 7 is pushed up by hydraulic pressure or the like so that it is flush with the main body portion 7'.
刃型２を複数並べて受型３をそれに相対して設
ければ、複数のバンド体１を同時に製造すること
ができる。 By arranging a plurality of blade molds 2 and providing a receiving mold 3 facing them, a plurality of band bodies 1 can be manufactured at the same time.

利である。 In actual manufacturing, a timer device is used to press the blade mold by applying pressure, weld by applying high frequency, then cool it, and then press the same surface and the blade mold again by rocking the receiving mold to cut, sequentially. It would be convenient if this could be done continuously and automatically.
なお、バンド体の形状は任意である。 Note that the shape of the band body is arbitrary.

４′を同時に切断し、同一の刃型によつて溶着と
切断を行なうことができる。 As described above, in this invention, the receiving mold 3 is divided and configured to be movable, so when welding by applying high frequency, the cutting mold is made into a stepped shape as described above. A strong electric field is generated only between the mold 2 and the main body part 7' of the receiving mold, and only the main body 4' of the band body can be dielectrically heated and welded.When cutting, the receiving mold 3 is moved as described above. By making them flush, the blade die 2 presses against the cylindrical part 7 and the main body part 7' of the receiving mold simultaneously and bites into the band material 6, thereby cutting the cylindrical part 4 of the band body. and the main body portion 4' can be cut at the same time, and welding and cutting can be performed using the same blade type.
それに対して従来のこの種製造方法は、例えば

して、切断を不確実にする欠点がある。 On the other hand, conventional manufacturing methods of this type, as seen in Japanese Patent Publication No. 47-45482 and Japanese Patent Publication No. 47-45483, have a structure in which the mold is not divided.
Unlike this invention, it is not possible to weld and cut the band body using only the same blade type. That is, when welding by applying high frequency, the main body part of the band body is welded with a first cutting edge with the cylindrical part of the band body released so that only the main body part of the band body can be welded. Cutting only the main body part of the band body with one blade type, and then preparing a second blade type to cut the cylindrical part of the band body, etc. not only takes time and effort, but also requires two steps of cutting. Therefore, there is a drawback that the cutting positions of the main body portion and the cylindrical portion may deviate, making cutting uncertain.

ことができる製造方法を提供する効果がある。 However, as described above, in this invention, the receiving mold is divided into a cylindrical part and a main body part and made movable, the cylindrical part is stepped when welding the band body, and the cylindrical part and the main part are flush with each other when cutting. Furthermore, by making the blade-shaped blade correspond to the outer periphery of the band body, it is possible to continuously weld and cut the band body with the same blade type, and furthermore, it is possible to simultaneously weld and cut the band body at the same time. This has the effect of providing a manufacturing method that can be performed in one step, solves the drawbacks of conventional methods, and allows welding and cutting operations to be performed easily and reliably.
