Description

Upper Manufacturing Method

The present invention relates to a manufacturing method for shoe uppers, in particular to a method that can not only set different heating temperatures and heating times according to different usage requirements, but also can set different heating temperatures and different heating times for the hot-melt bonding between shoe material fabrics of different materials and thermoplastic elastomers, and use A single upper mold is combined with multiple lower molds, which can effectively improve production efficiency and increase production capacity, and it has more practical and functional characteristics in its overall implementation and use.

By the way, humans have been able to walk and run in a standing posture. After hundreds of thousands of years of evolution and development, they know how to use leaves, bark, and even animal skins to wrap their feet. The purpose is nothing more than keeping warm and protecting their feet. And these shields that wrap the feet are the earliest prototypes of shoes.

Due to the progress of the times, the modern shoe-making industry splits shoes into multiple parts. These different parts include: vamp, sole, shoe root, insole, shoe last, shoelaces, accessories, etc. The department or production line manufactures in order from material preparation, pattern making, cutting, sewing, molding, topping, lasting, quality inspection, and finally packaging.

Among them, the traditional shoe-making industry is a labor-intensive industry with many types of raw materials and trivial manufacturing processes. Especially when making shoe uppers, the toughness of the material, whether the joint is reliable, whether the glue is used correctly, and whether the reinforcement should be reinforced. In addition, lining materials, lining materials, and reinforcing materials are properly matched and sewn together to make the upper. Therefore, there is a proverb in the shoe-making industry that says: "The difference in making clothes is the difference in making shoes", which means that it is difficult to make a pair of good shoes with high standards.
