Abstract

Procedimiento para la formación de elementos en relieve sobre una lámina, por deformación en caliente, caracterizado porque consiste en calentar una parte de la lámina correspondiente al relieve manteniendo a la vez a una temperatura baja las superficies situadas en el interior y en el exterior de esta parte y después en estirar para deformarla la parte caliente , impidiendo la rigidez de la parte fría su deformación.
