Abstract
Perfeccionamientos en los aparatos para el estiraje transversal de material tubular, impulsando continuamente el material por una estructura de mandril interior cuya sección transversal aumenta a lo largo de su longitud, caracterizados porque la estructura de mandril comprende un mandril de manera toroidal y porque hay medios de accionamiento asociados con la estructura de mandril corriente abajo del punto de sección transversal máxima del mandril (o el punto de comienzo de la zona de sección transversal máxima del mandril) para impulsar de manera friccional el manguito y el material tubular que se ha alimentado sobre el manguito a lo largo de la superficie exterior del mandril.
