細書に於て、表のシート材を表地、裏のシート材を裏地
と記す。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sheet material in which the upper part has two layers, front and back (hereinafter, in this specification, the front sheet material will be referred to as the outer material, and the back sheet material will be referred to as the lining).

た履物を開発することに成功した。) and a synthetic resin intermediate layer located between both sheet materials. The present inventor has succeeded in developing footwear with an excellent design, function, and comfort that surpass those of conventional footwear by inserting an outer material such as leather or fabric on the surface of the upper. .

る作業自体も手間が掛って難しく、生産性が悪い。However, the most difficult part of manufacturing footwear using this method is
The problem lies in how the outer material is temporarily attached to the positioning layer of the mold. This is because if the outer material is not temporarily fixed accurately in a fixed position, it will shift after molding, completely destroying its commercial value and significantly reducing the yield of footwear. The reason why it is difficult to temporarily fix the outer material in place in the mold is because the outer material is inserted into the surface of the upper and must be temporarily fixed inside the female mold. Even if some method is used, for example, by carving a recess into the female mold into which the outer material can be inserted, and then temporarily fixing the outer material by inserting iron into this recess, this method alone will not allow the ultra-high pressure synthetic resin to be press-fitted. It is difficult to hold the outer fabric in place due to the injection pressure. Therefore, even if the outer material of a temporary article can be temporarily fixed to the positioning layer and the mold can be closed, the outer material will be displaced by the melt pressure of the synthetic resin press-fitted during molding, and its commercial value will be completely destroyed. Further, the work of temporarily fixing the outer material inside the female mold itself is time-consuming and difficult, resulting in poor productivity.
本発明は、この欠点を一挙に解決すると共に、更にすぐ

履物の製造方法を提供するにある。The present invention solves these drawbacks at once, and has even more excellent features by connecting a part of the outer fabric to the lining so that it can be temporarily fixed to the male core through the lining. An important object of the present invention is to provide a lining that can be easily and easily attached to the outer material, can be attached together with the lining without much effort, and can be attached temporarily to the core without shifting its position. To provide a method for manufacturing footwear which is temporarily fixed to a positioning layer of a molding chamber in a state where the footwear does not shift accurately through the step, and which has good mass productivity and yield.
以下、本発明の実施例を図面に塞いて説明する。Embodiments of the present invention will be described below with reference to the drawings.

ト状部材等が使用される。Thereafter, as shown in FIG. 2, the core 3 and the female mold 4 are closed, and as shown in FIGS. The intermediate layer 6 is formed by press-fitting the synthetic resin. The outer material 2 shown in Figures 1 and 2 is
The upper green is connected to the green around the shoe opening of the lining 1, and the synthetic resin press-fitted presses the outer material 2 and the lining 1 onto the surfaces of the molding chambers of the female mold and core, respectively. The lining 1 has a closed injection hole 7 through which a synthetic resin is injected between the lining I and the outer material 2, and through this injection hole 7, the core 3 penetrates the lining 1 and is injected into the outer material 2 and the lining. 1 and a molten synthetic resin is press-fitted between the two. The outer material 2 is made of, for example, cloth, synthetic or natural leather, and the lining 1 is made of cloth, synthetic or natural leather, or a sheet-like member in which cloth is adhered to the surface of a synthetic resin sheet. .

リッパの場合甲皮部はバンドとなる。表地は、履物の種
類によって、甲皮部にインサートされる状態、即ち、甲
皮部の全面に表地をインサートされるとか、あるいは一
部にインサートするかが決定される。In the sandals shown in Fig. 2, the intermediate layer 5 is made of synthetic resin and is integrally molded with a footwear stand 6. In sandals with this structure, the footwear stand is molded at the same time as the band, which is the leather part, is molded. In addition, the step of hanging the band can be omitted, and the connection between the band and the footwear stand is strong, resulting in sandals with strong ruts.
Figures 1 and 2 show the molded state of the sandals.
The present invention does not limit the footwear to sandals, but also includes shoes and slippers, etc., and in the case of shoes and slippers, the outer material is connected to the lining material as in the above-mentioned slippers, thereby eliminating the need for lining or bands. It is possible to insert the outer material in certain places. However, in the case of shoes, the upper part becomes the upper skin, and in the case of sandals and slippers, the upper part becomes the band. Depending on the type of footwear, it is determined whether the outer material is inserted into the upper, that is, whether the outer material is inserted over the entire surface of the upper or only partially.
