Abstract
SE DESCRIBE UN PROCEDIMIENTO Y UN DISPOSITIVO PARA LA ELABORACION CONTINUA DE BLOQUES DE MATERIAL ESPONJOSO O BANDAS DE MATERIAL ESPONJOSO CON UNA SECCION TRANSVERSAL ESENCIALMENTE RECTANGULAR A BASE DE UNA MEZCLA DE REACCION LIQUIDA, ESPONJABLE, EVENTUALMENTE EN FORMA DE UN ESPONJAMIENTO PREVIO LIQUIDO. LA MEZCLA DE REACCION SE APLICA A PARTIR DE UN CABEZAL (2) DE MEZCLA ESTACIONARIO SOBRE UNA LAMINA (4) DE FORRO INFERIOR MOVIL, INCLINADA EN DIRECCION LONGITUDINAL, QUE SE ADICIONA DESDE ARRIBA A UNA LAMINA (8) DE CUBIERTA SUPERIOR, QUE ES APLICADA POR MEDIO DE UN ELEMENTO (10) DE INVERSION QUE SE SUMERGE EN LA MEZCLA DE REACCION EN CONTACTO CON LA MEZCLA (13) DE REACCION. EL ELEMENTO (10) DE INVERSION ESTA CONFIGURADO DE FORMA PLANA EN DIRECCION LONGITUDINAL DE TAL MODO, QUE ENTRE LA PARTE INFERIOR DE LA LAMINA (4) DE FORRO Y LA LAMINA DE CUBIERTA SUPERIOR, QUE SE GUIA A TRAVES DEL ELEMENTO DE INVERSION, SE CONFIGURA UN CANAL CON SECCION TRANSVERSAL ESENCIALMENTE CONSTANTE, CUYA DILATACIONL EN DIRECCION LONGITUDINAL SOBREPASA LA ALTURA H MEDIA MULTIPLES VECES. EL ELEMENTO (10) DE INVERSION ES OSCILANTE ALREDEDOR DE UN EJE (17) EN EL LADO DE ENTRADA ASENTANDOSE SOBRE LA MEZCLA DE REACCION CON CARGA A PRESION.
