Abstract

Se proporciona un método y aparato para orientación longitudinal de material (20) de película termoplástica que comprende una zona de reducción de anchura corriente arriba de la zona (9, 10) de estirado longitudinal, a través de lo cual se reduce gradualmente la anchura de la película de manera que permite el estirado longitudinal sin estrechamiento. La zona de reducción de anchura comprende por lo menos dos conjuntos de rodillos de plegado (7, 1) que comprenden surcos intermedios o discos para plegar el material. Los rodillos corriente abajo (1) comprenden un mini-rodillo definido por las siguientes medidas: a) el paso de los corrugados, medidos desde la parte media de la punta a la parte media de cada punta aledaña es de 20 mm o menor; b) el perímetro desde la parte media de un punta a la parte media de la siguiente punta aledaña, medido a lo largo de la superficie del rodillo corrugado, dividido entre el paso está en un intervalo entre 1.10 y 1.80; y c) el diámetro del mini-rodillo, medido en las puntas de los corrugados en el máximo, 4 veces el paso. Preferiblemente, un par de conjuntos de mini-rodillos se colocan en lados opuestos de la película en cantidades reciprocantes que permiten entre cruzado alternado de la película alrededor de uno u otro minirodillo. El método permite la obtención de una resistencia a la tensión elevada, un punto de flexibilidad y resistencia a la propagación del desgarre y resistencia a la perforación, especialmente para películas de polietileno y polipropileno.
