Abstract

SE DESCRIBE UN METODO PARA LA CONSTRUCCION DE UN CUERPO HUECO, DE MATERIAL ESPONJOSO, PERSISTENTE Y CONFORMABLE A TRAVES DE UN MOLDEO POR SOPLADO. SEGUN EL METODO, SE ENCAJAN EN PRIMER LUGAR UNO O MAS SEGMENTOS DE UN MATERIAL ESPONJOSO TRAS EL CALENTAMIENTO A UNA TEMPERATURA POR ENCIMA DE LA TEMPERATURA DE REBLANDECIMIENTO DE LA MATERIA ESPONJOSA EN UNA FORMA MULTIPARTIDA. A TRAVES DE LA FORMA DE MULTIPLES PARTES SE UNEN PREFERENTEMENTE LOS SEGMENTOS A LO LARGO DE SUS BORDES, SOLDADOS UNOS CON OTROS; Y EL ESPACIO INTERMEDIO ENTRE LOS SEGMENTOS ESTA PLENAMENTE IMPERMEABILIZADO. TRAS LA IMPLANTACION DE UN LIQUIDO QUE SE COLOCA A PRESION, PREFERIBLEMENTE DE AIRE, DENTRO DEL ESPACIO INTERMEDIO ENTRE LOS SEGMENTOS SE IMPRIMEN Y MODELAN LOS SEGMENTOS EN LAS PAREDES DE FORMA MULTIPLE. TRAS LA REFRIGERACION DE LOS ELEMENTOS SE DESMOLDEA LA PIEZA PERFILADA. ESPECIALMENTE SE APLICA, SEGUN LA INVENCION, MATERIAL ESPONJOSO DE POLIOLEFINO HUMEDO
