Abstract

Perfeccionamientos en dispositivos de moldeado de materias expansibles, y sobre todo para poliestirenos, que se caracteriza por lo que comprende esencialmente una pluralidad de moldes que están constituidos cada uno de ellos por dos relieves de escasa masa y poca capacidad calorífica, los cuales van perforados con una multitud de orificios a fin de que el vapor u otros gases puedan pasar a través de ellos y van montados de modo amovible e individualmente sobre las dos caras opuestas de dos bastidores, *** Ver imagen
