Abstract

PROCEDIMIENTO PARA LA FABRICACION CONTINUA DE BLOQUES DE ESPUMA POLIMERICA. EL INYECTOR (8) DEPOSITA, CON MOVIMIENTO ALTERNATIVO A LA BANDA BASE (9) EL MATERIAL (11), EL CUAL SE EXPANDE PROGRESIVAMENTE APOYANDOSE EN DICHA BASE MOVIL CONTINUA Y EN UNAS SUPERFICIES LATERALES FIJAS (16) CUBIERTAS POR UN RECUBRIMIENTO TUBULAR ENVOLVENTE MOVIL CONTINUO (17), QUE SE SEPARA DE LA ESPUMA CUANDO ESTA ALCANZA SU MAXIMA ALTURA Y ES CORTADO POR SENDAS CUCHILLAS (24, 25) Y ENROLLADO EN LOS RODILLOS RIGIDOS (30, 31). SE PUEDE VARIAR EL ANCHO DEL BLOQUE MEDIANTE APROXIMACION DE LAS SUPERFICIES LATERALES, TAMBIEN SE PUEDE CAMBIAR DE MATERIAL VARIANDO LA INCLINACION DE ESTAS Y DE LA BANDA INFERIOR. EXISTEN VARIANTES DE FORMA.
