Abstract

1. Un método para el estirado lateral continuo de películas a anchura constante, caracterizado porque una banda no estirada de material en forma de película reticular es hecha pasar a pares de rodillos de sujeción montados a uno y otro lados de la banda, que sujetan a ésta a la anchura deseada y que son controlados por un mecanismo de control de modo que, cuando la anchura de la banda se aparta de la deseada, se reajusta el ángulo comprendido entre los ejes de los rodillos de sujeción y los lados de la banda en el plano de ésta.
