Abstract

Aparato para la producción de una longitud continua de material celular polimérico a partir de una mezcla de reactivos líquidos de formación de espuma, que incluye una cubeta con parte superior abierta en la cual la espuma líquida puede dilatarse hacia arriba, un dispositivo para suministrar los reactivos líquidos de formación de espuma al fondo de dicha cubeta, una estructura de barrera asociada con dicha cubeta de modo que la espuma que sube por dilatación en ella fluya por encima de dicha estructura de barrera, un transportador en forma de canal en "U" con parte superior abierta asociado con dicha estructura de barrera y dispuesta para transportar continuamente la espuma que se dilata alejándola de la estructura de barrera mientras completa su proceso de expansión, incluyendo el transportador en forma de perfil en U con parte superior abierta una pared de fondo y unas paredes laterales separadas que se unen a dicha pared de fondo y unas paredes laterales separadas que se unen a dicha pared de fondo río abajo de la estructura de barrera, incluyendo también el aparato unos medios que pueden ser accionados para alterar la longitud de la cubeta y unos medios de reglaje de la anchura de transportador que pueden ser accionados para cambiar la anchura de la pared de fondo del transportador en forma de perfil en U y para desplazar sus paredes laterales de manera correspondiente, en sincronismo con los cambios de anchura de dicha pared de fondo, y un dispositivo de estanqueidad para mantener una junta hermética en la zona donde las paredes laterales en forma de perfil en U durante los cambios de anchura, con lo cual pueden fabricarse anchuras variables de material celular sin detener la producción.
