Abstract
Procedimiento para la fabricación de bloques rectangulares de material de espuma, de una mezcla de reacción espumable, especialmente de una mezcla de poliuretano, con curso de superficie ajustable, con preferencia muy plano y con cantos agudos, mediante aplicación de procedimientos conocidos de espumación en rectángulo, en que la mezcla de reacción se aplica sobre un banda de fondo, que se mueve avanzando, caracterizado porque la mezcla de reacción, que sale de la cámara mezcladora, se controla de tal manera que se actúa antagónicamente a las diferencias de altura que se presentan normalmente.
