Abstract

El invento se refiere a un procedimiento para el estiramiento en direccion longitudinal de una lámina de por lo menos una capa a base de un material sintético termoplástico. La parte del equipo de estiramiento que se mueve lentamente contiene por lo menos un rodillo propulsado y la parte del equipo de estiramiento que se mueve rápidamente contiene por lo menos dos rodillos propulsados, estando dispuesto el par de rodillos de manera tal que se forma una rendija entre rodillos, dentro de la cual es conducida a la lámina de manera tal que es aprehendida y estirada simultáneamente por el par de rodillos.
