"THE MOLDING DEVICE FOR STRETCHING CAN BODIES", comprises a hard and solid forming block made of steel or any other harder material. It is generally cylindrical which presents the biggest part of its height with a larger diameter corresponding to the inner diameter of the can already stretched having on its upper part a conic section topped by a short cylindrical section with a smaller diameter corresponding to the inner diameter of the can body to be stretched. The forming block receives from below, where it seats, a flange forming tool at the lower part of the can body, the tool formed by a steel disk having a circular groove in fluting section, susceptible to be reached and taken by the lower end of the can body on its stretching and molding process. It is further provided with a flange forming tool on the upper part of the can formed by a steel disk provided on its lower face with a circular groove of a fluting section and having a small circular and salient section which surrounds the inner periphery of the groove. The salient section may be maintained by coupling on the upper end of the can body that will be stretched and molded.
