Abstract

Para la fabricacion continua de un tubo compuesto, con manguito de tubo (41), que consta de un tubo interior liso y un tubo exterior provisto de ranurastransversales y soldado a aquél, se han previsto dos máquinas de extrusion, que realizan laextrus ion de un tubo flexible exterior (37) y un tubo flexibleinterior (39) por medio de una cabeza transversal comun de inyeccion (8). Para la fabricacion de un manguito de tubo (41) están provistos interruptores(50, 51, 56, 57), mediante loscuales se mo difica el numero de revoluciones de las máquinas de extrusion, de manera que, durante la fabricacion del manguito detubo (41), se reduce la corriente de masa fundida de plástico para fabricar el tubo flexible exterior (37) y/o seaumenta la corrient e de masa fundida deplástico para fabricar el tubo flexible interior (39).
