用プリ７しグジートに関するものである。DETAILED DESCRIPTION OF THE INVENTION The second invention in the industrial application field relates to an efficient manufacturing method for shoes having partially reinforced parts such as the toe part and the heel part, and further relates to a shoe reinforcing pre-7 used for manufacturing the shoes. It is about Shigjit.

入する必要に迫られる。As is well known, shoes require more reliable reinforcement depending on the shape of the toe, heel, etc., and depending on the intended use. For example, safety shoes for work require a reinforcing member made of steel or a hard plastic with comparable strength to be inserted into the toe part.

A sheet material integrated with a plastic material or a sheet material integrated with a hot-melt adhesive component such as polycaprolactone is temporarily attached to a predetermined part of the shoe cover before molding, and after heating, softening, and forming molding, Cooling methods were used. However, this conventional technique has the following problems.

難とされていた熱硬化性樹脂の利用に着目した。That is, 2) the hardness of the obtained reinforcing member is low. Especially the above f
P: Forming a reinforcement part made of iron or comparable in strength to the toe part, like in industrial safety shoes, is an excellent option. This is due to the unique properties of thermoplastic materials. Even if we tried to solve the second problem by increasing the thickness of the reinforcing member, it would be necessary to make it unnecessarily thick, which would not only make the shoe molding process extremely difficult, but also make the shoe bulky and warp, increasing the danger. 2) Thermoplastic materials such as polystyrene, vinyl chloride, and vinyl acetate, and hot-melt adhesive components such as polycaprolactone cannot be used unless the temperature drops to about 40°C to 25°C. Because plasticity remains and the product loses its shape, it is necessary to wait for the final temperature to drop after the heating process before cutting it out. Therefore, after the shoe is molded, it is necessary to naturally cool the shoes attached to the last, which increases the amount of work in progress and significantly reduces manufacturing efficiency. In order to solve this problem, extra processes and equipment such as forced cooling are required. We focused on the use of thermosetting resins, which had been considered to be effective.
