Abstract
Procedimiento para la fabricación de tubos de plástico de doble pared; en los que la pared exterior lleva ondulaciones transversales, mientras que la pared interior es lisa, siendo producidas en las ondulaciones transversales por medio de unas coquillas circulatorias, caracterizado porque en las ondulaciones transversales anulares de la pared exterior, son realizadas en ésta o entre las dos paredes unas aberturas que unen las cámaras interiores de las ondulaciones transversales entre si con el espacio exterior y son cerradas por soldadura después del enfriamiento del tubo interior.
