Abstract

Dispositivo para la aplicación de una mezcla de reacción formadora de material espumado, de como mínimo dos componentes fluibles sobre un substrato en movimiento, compuesto de depósitos de almacenamiento desde los cuales tuberías de alimentación conducen a través de bombas dosificadoras hacia un cabezal mezclador, cuya salida está conectada a través de tuberías de alimentación, con una viga de aplicación dispuesta transversalmente sobre el substrato en movimiento, provista de una ranura de toberas, caracterizado porque en la viga de aplicación se disponen varios escotes uno al lado del otro, que desde las desembocaduras de la tubería de alimentación se ensanchan en forma de abanico formando una ranura de tobera común siendo la longitud de la conducción desde la salida del cabezal mezclador hasta las desembocaduras igual de grandes y disminuyendo la profundidad de los escotes hacia la ranura de tobera de manera que se mantenga una sección de flujo constante.
