Abstract
A process for the manufacture of rubber footwear, essentially characterized in that a rubber sole, preformed, is joined to an instep also preformed with its lining, by pressure of air or other fluid, which is also maintained during the vulcanization of the aforementioned parts of the footwear, the sole and instep being assembled in corresponding hollow molds provided with means for carrying out their successive hermetic connection and the pressure of the air or other fluid being exerted inside the hollow mold in which it has been previously introduced the instep, the internal surface of the hollow mold presenting negative incisions of the drawings that eventually must be molded by the pressure of the fluid on the surface of the corresponding instep.
