（産業上の利用分野）
この発明は、甲材の表面が樹脂層で覆われ、かつ底部を
二層構造からなる樹脂層で成形する靴の製造法に関する
ものである。[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a method for manufacturing shoes in which the surface of the upper is covered with a resin layer, and the bottom is molded with a resin layer having a two-layer structure. .
（従来の技術）
表面が樹脂層で覆われている靴の、従来の製造方法は、
特許６３−２７９８０１に見られるごとく、表底と甲被
樹脂層とが同時に一体成形されるものであった。(Prior art) The conventional manufacturing method for shoes whose surfaces are covered with a resin layer is as follows:
As seen in Patent No. 63-279801, the outsole and the upper resin layer were integrally molded at the same time.
（発明が解決しようとする問題点）
上記従来の靴製造方法の問題点は、表底と甲被とか同時
に一体成形されるため、両者の材質、発泡倍率、色など
すべてが必然的に同一属性のものとなり、表底と甲被の
色や発泡倍率（耐摩耗性、硬さ、などに影響）、材質な

、耐熱性などが要求されるのに対して、甲被は良質の触
感や美観などが求められるというように、両者は、色、
発泡倍率、材質等を異ならせることを求められることが
多い。(Problems to be Solved by the Invention) The problem with the conventional shoe manufacturing method described above is that because the outsole and the upper are integrally molded at the same time, the materials, foaming ratio, color, etc. of both are necessarily the same. Even if one wanted to change the color, foaming ratio (affecting abrasion resistance, hardness, etc.), material, etc. of the outsole and upper, it would not have been possible. However, for example, the outsole is required to have abrasion resistance, oil resistance, heat resistance, etc., while the upper is required to have a good feel and aesthetic appearance.
It is often required to vary the foaming ratio, material, etc.
発明者は、甲被の部分と表底の部分とを同時かつ一体的
でなく、二段階またはそれ以上に分けて成形すれば、こ
れらの問題点が解決できることに着目した。The inventor noticed that these problems could be solved by molding the upper part and the outsole part in two or more stages, instead of molding them simultaneously and integrally.
すなわち、第一段階で甲被および表底第一層を成形し、
第二段階で表底第二層を形成すれば、両者の色、発泡倍
率、材質は任意のものに設定することか可能である。That is, in the first step, the instep and the first layer of the outsole are formed,
If the second layer of the top and bottom is formed in the second step, the color, expansion ratio, and material of both can be set to any desired value.
さらに、最近、表底部分は、たとえば対摩耗性を有する

明者は表底部分を二段階で成形すればこれに応えられる
ことに着目した。Furthermore, recently, outsole parts are often required to have multiple properties, such as being required to have abrasion resistance and impact resistance at the same time. It is necessary to mold it from the following materials. The inventor noticed that this could be achieved by molding the top and bottom parts in two stages.
また、甲被として樹脂層が形成される部分は、外観上甲
材かがくれて見えなくなるので、その部分を切欠いだ甲
材を採用することも可能であり、この点で甲材の節約に
寄与できるし、素材を縫製して継ぎあわせたもの、ある
いは１枚もの等多様な甲材を使用することも可能である
。In addition, since the part where the resin layer is formed as the upper cover is hidden in appearance and becomes invisible, it is also possible to use an upper with a cutout in that part, which saves on the use of the upper material. It is also possible to use a variety of upper materials, such as those made by sewing and joining materials, or one piece.

ことを特徴とする靴の製造方法である。(Means for solving the problem) This manufacturing method involves suspending the upper material and the insole from the last, and then attaching it to the outer surface of the upper of the shoe and from the midsole to just before the outer surface of the finished outsole. It is held in a first female mold that has a kiahiti of the same shape as the outer shape of the temporary sole set in the first female mold, and the first female mold and the upper material, and the first female mold and the middle. Resin such as foamed polyurethane is injected into the gaps formed between the sole and the upper, and the first layer of the outsole is molded with the resin layer.Then, this state is used as the finished surface of the shoe. It is held in a second female mold that has a cavity with the same shape as the outer surface of the bottom, and a resin such as foamed polyurethane is injected into the gap formed between the mold and the second female mold to form the second layer of the top and bottom. This is a method of manufacturing shoes characterized by molding them with a resin layer.

合致する形状を有するキャビティ７が設けられている。(Example) As shown in FIG. 3, the upper material 2 is hung on the last 5 and held in the corresponding position of the first female mold 6. This first female mold 6 is the upper material 2
The purpose is to form an instep resin layer 3 on the surface of the shoe and to form a first outsole layer 4a on the outside of the midsole 9. A cavity 7 having a shape matching the outer shape of the upper part of the shoe is provided.
第一雌型６と甲材との間には甲被樹脂層３用の隙間８が
形成されており、また中底９と割型の一部である雌型６
ｂとの間には数ｍｍの隙間１０を設ける。これは表底第
一層４ａを形成することを目的としている。A gap 8 for the upper resin layer 3 is formed between the first female mold 6 and the upper material, and a female mold 6 that is a part of the inner sole 9 and the split mold is formed.
A gap 10 of several mm is provided between the The purpose of this is to form the outsole first layer 4a.
この隙間１０は、中底９よりは表底に近く、完成表底外
形面よりは中底９に近い範囲内で任意に設定される仮表
底外形面にて確保されるものである。This gap 10 is secured by a temporary outsole outer surface that is arbitrarily set within a range that is closer to the outsole than the insole 9 and closer to the insole 9 than the completed outsole outer surface.

る。In this state, a resin such as polyurethane foam is injected into the gaps 8 and 10. In the case of foamed resin, it is molded while expanding under its own foaming pressure, so there is no need to apply pressure during injection, but in the case of non-foamed resin, it may be necessary to press fit.
次に、ラスト５に吊り込まれ甲被に甲被樹脂層３を成形

完成する。Next, the product suspended in the last 5 and having the upper resin layer 3 molded and coated on the upper is held in the second female mold Yl as shown in FIG. 5 at this time (female mold 11 which is part of the mold)
Although it is possible to use the female mold 6b as is, it is preferable to prepare a separate mold for a. The female mold 11b is provided with a cavity 12 having a shape that matches the outer shape of the 1-formed surface and bottom. Next, a resin such as foamed polyurethane is injected into the gap 13 between the second female mold (i) and the outsole first layer 4a to form the outsole second layer 4b. After the resin hardens, the mold is removed. Once removed, the desired molded shoe is completed.
また、甲被樹脂層と表底第一層の形状、材質、色は自由

できる。In addition, when foamed polyurethane is used as the resin, a material with a low foaming ratio is used for the second layer of the outsole to improve wear resistance, and a material with a high foaming ratio is used for the resin layer of the upper and the first layer of the outsole. In addition to increasing the flexibility of the instep and heel by using the same material, in addition to increasing the number of colors, health performance and physical performance are improved, and demand is expected to be stimulated.
