Abstract

Perfeccionamientos en dispositivos para la obtención discontinua de material espumado en bloque, en el cual se ha dispuesto un aparato mezclador dotado de tuberías de alimentación de los componentes y de un agitador, y que se puede mover verticalmente en un armazón bastidor en forma de puente, y que como contenedor mezclador lleva un envolvente cilíndrico sin fondo dispuesto en una placa cabezal y colocable sobre el fondo de una caja de molde dispuesta debajo, caracterizado porque sobre el fondo de la caja de molde se dispone una capa elásticamente flexible cubierta por encima de una lámina de material sintético.
