Abstract

Procedimiento para la fabricación continua de un tubo compuesto (10), con un manguito de tubo (41), que consta de un tubo interior liso (39¿) y un tubo exterior (37¿) soldado a aquél y provisto de ranuras transversales (38), con las siguientes operaciones del procedimiento: - se extruye un tubo flexible exterior (37), - el tubo flexible exterior 37 es provisto de una ondulación con ranuras transversales (38) por medio de una presión positiva relativa, que actúa desde dentro hacia fuera, generada al menos parcialmente mediante un vacío parcial aplicado desde afuera, - se extruye un tubo flexible interior (39) en el tubo flexible exterior (37), - el tubo flexible interior (39) es presionado contra los valles (40) de las ondulaciones del tubo flexible exterior (37) y es allí soldado con el tubo flexible exterior (37), - el tubo flexible exterior (37) es ensanchado a distancias prefijadas, aplicando la presión positiva relativa que actúa desde dentro hacia fuera, para formar un manguito de tubo(41) aproximadamente cilíndrico y esencialmente con paredes lisas, caracterizado porque: por lo menos una de las corrientes de masa de material fundido de plástico por unidad de tiempo, utilizadas para la fabricación del tubo flexible exterior (37) y del tubo flexible interior (39), es modificada durante la fabricación del manguito de tubo (41), independientemente de la otra corriente de masa.
