  • Method of manufacturing shoes
    Patent number: 4777733
    Abstract: In a method of manufacturing shoes, shoes which are integrated by securing bottoms to ones assembled by joining the edges of uppers and insoles fitted to shoe lasts, are taken in a rapid freezing atmosphere cooled by liquefied gas, in which the surfaces thereof are cooled rapidly. The effect of rapid cooling makes it possible to manufacture shoes which maintain their shape when fitted in correspondence to the shoe lasts without causing any disfigurement thereafter as well as shortening the manufacturing time.
