本願のような時計バンドの製造方法において問
題になる点は、バンド体の溶着と切断に際して、
バンド体の筒部をどのような方法で加工するかに
あります。 The problem with the method of manufacturing a watch band as in the present application is that when welding and cutting the band body,
It depends on the method used to process the cylindrical part of the band body.

に行なうことを目的としたものである。 That is, in order to insert a pin or the like, it is necessary to open both sides of the cylindrical part of the band body to the outer periphery of the band body, so when welding, only the main body part of the band is welded and the cylindrical part is To avoid welding, it is necessary to cut the cylindrical part and the main body part as one piece when cutting, but this invention uses the same blade type and cuts the main body part of the band body excluding the cylindrical part when welding. The purpose is to easily and reliably perform the work of welding and cutting the band body by simultaneously cutting the cylindrical part of the band body in one piece when welding and cutting (or cutting) the band body. It is.

る。 One embodiment of the invention will be described with reference to the drawings. The manufacturing method of the present invention uses a known high-frequency welding machine made of a conductive material such as steel having a blade 2' corresponding to the outer periphery 1' of the band body 1. A blade mold 2 and a receiving mold 3 facing the blade mold are installed. A band material 6 made of a flexible material such as natural or synthetic leather or fibers which has been polymerized with the band material 6 before welding and cutting the band body 1 is placed thereon, and a receiving mold 3
is divided into a cylindrical portion 7 corresponding to the cylindrical portion 4 of the band body, a main body portion 4′ of the band body excluding the cylindrical portion, and a corresponding main body portion 7′, and the cylindrical portion 7 is made of an insulating material such as plastic material. By making the main body portion 7' of a conductive material such as steel, the blade 2 can be connected to the band material 6.
When welding the front and back materials 5, 5' along the outer periphery 1' of the band body by applying high frequency waves using the blade mold 2 and the receiving mold 3 as electrodes, the main body part 4' of the band body By welding only the cylindrical part 7 and the main body part 7' of the receiving mold on the same surface (flush), when cutting the outer periphery 1' of the band body by further pressing the cutting mold 2, Another feature is that the cylindrical portion 4 and main body portion 4' of the band body are cut at the same time.

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 butt portion of the front and back materials 5 and 5'. 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 part 4' in a polymerized state.For welding the entire surface, a press mold is used instead of the blade mold 2 of the embodiment. This makes it easy to weld. If a plurality of blade molds 2 are arranged and a receiving mold 3 is provided facing them, a plurality of band bodies 1 can be formed.
can be manufactured at the same time.

なお、図面に示した刃型と受型は概略の構造を
示すものであり、バンド体の形状等も任意であ
る。 It should be noted that the blade mold and the receiving mold shown in the drawings show the general structure, and the shape of the band body etc. can be arbitrary.

切断を行なうことができる。 As described above, this invention is achieved by dividing the receiving mold 3, configuring the cylindrical portion 7 with an insulating material and the main body portion 7' with a conductive material, and configuring the cylindrical portion and the main portion on the same surface. When welding by applying high frequency, a strong electric field is generated only in the main body part 7' of the blade die 2 and receiver die, and only the main body part 4' of the band body is dielectrically heated and can be welded. In this case, the blade die 2 simultaneously presses against the cylindrical part 7 and the main body part 7' of the receiving mold and bites into the band material 6, thereby cutting the cylindrical part 4 and the main body part 4' of the band body at the same time. The blade shape allows welding and cutting.

断を不確実にする欠点がある。 On the other hand, conventional manufacturing methods of this kind do not divide the mold, as seen in Japanese Patent Publication No. 47-45482 and Japanese Patent Publication No. 47-45483, and
Since it is not composed of an insulating material and a conductive material, it is not possible to weld and cut the band body using only the same blade type as in the present invention. That is, when welding by applying high frequency, the main body part of the band body is welded with a first blade type 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 of the band body with a second blade type, and then preparing a second blade type to cut the cylindrical part of the band body. This has the disadvantage that the cutting positions of the main body and the cylinder may be misaligned, making the 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 configured flush and divided into a cylinder part and a main body part, the cylinder part is made of an insulating material, the main part is made of a conductive material, and the mold is made of a conductive material. By using a blade with a blade shape that corresponds 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.
